RESUMO
The Villa Victoria dam is one of the most important storage reservoirs in Mexico since it distributes water to more than 20 million inhabitants in the Metropolitan Zone of Mexico City. In this dam, the common carp (Cyprinus carpio) is an important food resource for the inhabitants, so the aim of this work was to evaluate the oxidative damage (lipoperoxidation, oxidized proteins, antioxidant enzymes activity and gene expression), AChE, embryotoxicity and behavioral changes in C. carpio embryos and larvae exposed to water from Villa Victoria dam for 24, 48, 72 and 96 h. The embryotoxicity was evaluated trough the General Morphology Score (GMS) and the teratogenic index. Behavioral changes in basal locomotor activity and thigmotaxis were evaluated in a DanioVision, Noldus ™. An increase in lipid and protein oxidation as well as modification of CAT, SOD and GPx enzymatic activity was observed during the exposure times. The GMS indicated a low development in the embryos, the teratogenic index was less than 1, however teratogenic effects as yolk edema, fin malformation, head malformation and scoliosis were observed. In parallel, an increase in AChE activity and gene expression was observed reflecting changes in distance traveled of the basal locomotor activity and thigmotaxis at the sampling points. In conclusion, pollutants in water from Villa Victoria dam caused oxidative damage, changes in SOD, CAT, GPx and AChE activity as well as embryotoxicity and modifications in the behavior of C. carpio larvae. This study demonstrates the need to implement restoration programs for this reservoir since, contamination in the Villa Victoria dam could eventually endanger aquatic life and human health.

The pathophysiology of post-traumatic brain injury (TBI) behavioral and cognitive changes is not fully understood, especially in its mild presentation. We designed a weight drop TBI model in mice to investigate the role of neuroinflammation in behavioral and cognitive sequelae following mild TBI. C57BL/6 mice displayed depressive-like behavior at 72 h after mild TBI compared with controls, as indicated by a decrease in the latency to first immobility and climbing time in the forced swim test. Additionally, anxiety-like behavior and hippocampal-associated spatial learning and memory impairment were found in the elevated plus maze and in the Barnes maze, respectively. Levels of a set of inflammatory mediators and neurotrophic factors were analyzed at 6 h, 24 h, 72 h, and 30 days after injury in ipsilateral and contralateral hemispheres of the prefrontal cortex and hippocampus. Principal components analysis revealed two principal components (PC), which represented 59.1% of data variability. PC1 (cytokines and chemokines) expression varied between both hemispheres, while PC2 (neurotrophic factors) expression varied only across the investigated brain areas. Our model reproduces mild TBI-associated clinical signs and pathological features and might be a valuable tool to broaden the knowledge regarding mild TBI pathophysiology as well as to test potential therapeutic targets.

In a previous Argentine study, we found that, in the critical context of social isolation during the COVID-19 pandemic, there were changes in maternal practices that influenced the relationship with their children. We also found that the impact of mandatory isolation was moderated positively by protective factors such as positive parenting and maternal school support or negatively by risk factors such as maternal stress. Although this study only analyzed maternal behavior, we were interested in studying the behavior of both parents, comparing the parenting (positive parenting, parental stress, and school support) of the father and mother and the perceived behavioral changes in their children. A quantitative ex post facto study was carried out. The sample consisted of 120 Argentinean parents (70 mothers and 50 fathers) aged between 27 and 56 (M = 38.84; SD = 5.03). Questionnaires were administered on sociodemographic and behavioral data of the children, as well as a brief scale to assess parenting. Mann-Whitney U and MANOVA were used to analyze the influence of gender on perceived changes in children's behavior and perceived parenting, respectively. Mothers perceived more significant changes than fathers in their children's behavior. In addition, women reported more parental stress, greater child school support, and greater perceived positive parenting compared to men. These findings support the hypothesis that parenting developed differently in fathers and mothers. These results imply the need for psycho-educational intervention programs aimed at promoting greater involvement of fathers in parenting and better management of parental stress in mothers' and family psychological well-being.

Toll-like receptors (TLRs) are central players in innate immunity responses. They are expressed in glial cells and neurons, and their overactivation leads to the production of proinflammatory molecules, neuroinflammation, and neural damage associated with many neurodegenerative pathologies, such as Huntington's disease (HD). HD is an inherited disorder caused by a mutation in the gene coding for the protein Huntingtin (Htt). Expression of mutated Htt (mHtt) causes progressive neuronal degeneration characterized by striatal loss of GABAergic neurons, oxidative damage, neuroinflammatory processes, and impaired motor behavior. The main animal models to study HD are the intrastriatal injection of quinolinic acid (QA) and the transgenic B6CBA-Tg (HDexon1)61Gpb/1 J mice (R6/1). Those models mimic neuronal damage and systemic manifestations of HD. The objective of this work was to study the participation of TLR4 in the manifestations of neuronal damage and HD symptoms in the two mentioned models. For this purpose, C57BL6/J and TLR4-KO mice were administered with QA, and after that motor activity, and neuronal and oxidative damages were measured. R6/1 and TLR4-KO were mated to study the effect of low expression of TLR4 on the phenotype manifestation in R6/1 mice. We found that TLR4 is involved in motor activity, and neurological and oxidative damage induced by intrastriatal injection of QA, and the low expression of TLR4 causes a delay in the onset of phenotypic manifestations by the mHtt expression in R6/1 mice. Our results show that TLR4 is involved in both models of HD and focuses then as a therapeutic target for some deleterious reactions in HD.

Pyrrolizidine alkaloids (PAs) are secondary plant metabolites playing an important role as phytotoxins in the plant defense mechanisms and can be present as contaminant in the food of humans and animals. The PA monocrotaline (MCT), one of the major plant derived toxin that affect humans and animals, is present in a high concentration in Crotalaria spp. (Leguminosae) seeds and can induce toxicity after consumption, characterized mainly by hepatotoxicity and pneumotoxicity. However, the effects of the ingestion of MCT in the central nervous system (CNS) are still poorly elucidated. Here we investigated the effects of MCT oral acute administration on the behavior and CNS toxicity in rats. Male adult Wistar were treated with MCT (109 mg/Kg, oral gavage) and three days later the Elevated Pluz Maze test demonstrated that MCT induced an anxiolytic-like effect, without changes in novelty habituation and in operational and spatial memory profiles. Histopathology revealed that the brain of MCT-intoxicated animals presented hyperemic vascular structures in the hippocampus, parahippocampal cortex and neocortex, mild perivascular edema in the neocortex, hemorrhagic focal area in the brain stem, hemorrhage and edema in the thalamus. MCT also induced neurotoxicity in the cortex and hippocampus, as revealed by Fluoro Jade-B and Cresyl Violet staining, as well astrocyte reactivity, revealed by immunocytochemistry for glial fibrillary acidic protein. Additionally, it was demonstrated by RT-qPCR that MCT induced up-regulation on mRNA expression of neuroinflammatory mediator, especially IL1ß and CCL2 in the hippocampus and cortex, and down-regulation on mRNA expression of neurotrophins HGDF and BDNF in the cortex. Together, these results demonstrate that the ingestion of MCT induces cerebrovascular lesions and toxicity to neurons that are associated to astroglial cell response and neuroinflammation in the cortex and hippocampus of rats, highlighting CNS damages after acute intoxication, also putting in perspective it uses as a model for cerebrovascular damage.

Aim of the present study was to assess physical activity, nutrition and psychological status of the population during lockdown due to covid-19. Online survey was conductedamong 534 participants within the age range of 16-78 years using convenient sampling. Participantsfrom varied regions within India and abroad were enrolled for the present study. Volunteered participants were solicited to take part in a survey that has to be carried out by filling an online questionnaire form available to them as a URL link in the invitation through WhatsApp/Messenger. The gathered data has been compiled, coded and cleaned using Microsoft Excel. Analysis has been carried out employing descriptive and inferential statistics in SPSS 17.0.Majority of participants in the studied population showed significant change in their nutrition and physical activity status due to lockdown. Covid-19 lockdown did limit their daily activities. It also had impacted their psychological status.The current investigation accentuates the need to pursue suitable life style for the maintenance of optimum metabolism and physiology. Sticking to more regular timetable of meals, effective management of stress levels and continued physical activity during the quarantine and in all the following phases of living is desirable.

Aedine mosquitoes go through unfavorable periods as dormant eggs. However, extended dormancy times lead to a depletion of egg reserves, which might be partially compensated by changes in larval-feeding behavior. Changes in larval behavior may also be induced by parasitism by mermithids probably as a strategy to reduce the impact of the parasite on the host. The most abundant floodwater mosquito in southern South America is Aedes albifasciatus (Diptera: Culicidae), a species naturally parasitized by Strelkovimermis spiculatus (Nematoda: Mermithidae). This study aimed to evaluate the behavior of fourth-instar larvae of Ae. albifasciatus from eggs with 2, 4, and 6 months of dormancy, parasitized or not by S. spiculatus. To achieve this, eight categories of behavior were defined, and then, each individual was observed for 5 min, and its behaviors and their duration were recorded. The behaviors with the highest percentage of observation time were still (50.1%) and wriggle swimming (33.6%), while those with the lowest percentage of observation time were those involving active foraging (less than 8%). A great variability in the behaviors was observed among individuals within the same treatment. The type and duration of each behavior did not vary in relation to egg dormancy time or parasitism, but parasitism affected the level of larval activity. Parasitized larvae performed, on average, fewer behaviors than non-parasitized larvae. This result supports the hypothesis that S. spiculatus parasitism affects the behavior of Ae. albifasciatus larvae by reducing their level of activity.

Foi investigado, nesse artigo, a forma com que a terapia narrativa, a partir da construção de histórias alternativas, pode estimular a plasticidade neuronal, promovendo mudanças psicológicas e comportamentais. Realizou-se uma revisão bibliográfica para analisar as contribuições teóricas e práticas da relação entre histórias alternativas e a neuroplasticidade. Foi observado que esta interface tem sido pouco estudada enquanto tema unificado. Na terapia narrativa o terapeuta ajuda o paciente a olhar detalhes até então não percebidos de sua história, trazendo novos estímulos e permitindo ao paciente recontar repetidas vezes sua própria história alternativa. Isso contribui para uma ressignificação de sua história e o desenvolvimento de novos pensamentos e sentimentos, que resultarão em novos comportamentos. A vivência desse processo, ativa a neuroplasticidade do cérebro e cria novas conexões neuronais, gerando mudanças saudáveis e funcionais na vida do paciente.
This work investigates how narrative therapy can stimulate neuroplasticity, with basis on the construction of alternative histories, thus promoting psychological and behavioral changes. A literature review was carried out to analyze the contribution, theoretical and practical, arising from the relationship between neuroplasticity and alternative histories. It was noticed that this interface has been little studied as a unified theme. In narrative therapy, the therapist helps the patient to look at details of his/her history so far unnoticed, bringing new stimuli and allowing the patient to recall his/her alternative history, over and over again. This contributes to a resignification of his/her history and the development of new thoughts and feelings, which will result in behavioral changes. The experience of the process of creating and recalling such alternative history, activates brains neuroplasticity, establishing new neural connections and contributing to healthy and functional changes in the patient's life.
RESUMO
CASE SUMMARY: This case report describes a 9-year-old neutered male cat with a functional adrenal tumor showing aggression toward other cats in the household, excessive meowing and urine spraying. The diagnosis was made based on the clinical signs, an enlarged right adrenal gland on ultrasound, penile spines and elevated sex hormones on an adrenocorticotropic hormone stimulation test. The cat was submitted to celiotomy and adrenalectomy. Histopathological examination confirmed the adrenocortical adenoma. Three months after surgery the penile spines disappeared and urine spraying, as well as excessive meowing, had greatly decreased; however, aggressive behavior took much longer to stop and required behavior therapy. RELEVANCE AND NOVEL INFORMATION: Functional adrenal tumors producing only sex hormones and behavioral changes are uncommon. The cat reported herein started showing behavioral changes before spines appeared on the penis, and structural alterations in the adrenal gland at the abdominal ultrasonography were detected. Considering all the possible implications resulting from severe behavior problems such as cat-cat aggression, from a permanent separation of the cats to relinquishment, a detailed investigation of underlying medical mechanisms in these animals is crucial from the start. Examinations may need to be repeated later in the course.
RESUMO
The exploitation of coal is an important resource to generate energy worldwide. However, during the processes of coal extraction, transport, and cargo, dust particles are released into the environment. The aim of this study was to determine the toxicological effects of bituminous coal dust (<38 µm), obtained from a sample collected in a coal mine in Colombia, on the annelid Eisenia fetida. The earthworm culture was standardized under laboratory conditions to evaluate mortality, as well as morphological, physiological and histological changes using concentrations varying from 1 to 4% w/w coal dust in artificial soil, after 7, 14, and 28 days of exposure. In addition, an avoidance assay was carried out after 48-h treatment. Histopathological analysis was performed at the end of the experiment. After the sub-chronic exposure, an increase in mortality was observed at the highest coal dust concentration compared to the untreated group. Alterations in morphology and physiology of the exposed annelids were mostly evidenced at the greatest tested concentrations (3-4%) and exposure times (≥14 days). Changes included loss of weight and color, abundant mucus production, constriction, peeling of the epidermis, clitellum involution, violent movements and lethargy. Avoidance of coal dust-polluted soil followed a concentration-response relationship. Histopathological findings revealed changes on the cuticle, as well as in the circular and longitudinal muscle layers in animals living in soils containing 3 and 4% coal particles. In short, E. fetida exposed to coal dust experienced several pathological changes, suggesting that this pollutant may induce population problems in macroinvertebrates present in coal mining areas.

OBJECTIVE: Establishing a social contact data sharing initiative and an interactive tool to assess mitigation strategies for COVID-19. RESULTS: We organized data sharing of published social contact surveys via online repositories and formatting guidelines. We analyzed this social contact data in terms of weighted social contact matrices, next generation matrices, relative incidence and R[Formula: see text]. We incorporated location-specific physical distancing measures (e.g. school closure or at work) and capture their effect on transmission dynamics. All methods have been implemented in an online application based on R Shiny and applied to COVID-19 with age-specific susceptibility and infectiousness. Using our online tool with the available social contact data, we illustrate that physical distancing could have a considerable impact on reducing transmission for COVID-19. The effect itself depends on assumptions made about disease-specific characteristics and the choice of intervention(s).

Dural arteriovenous fistulas (DAVFs) represent 10-15% of intracranial arteriovenous malformations. Of these, only 12-29% cause intracranial hemorrhage. The presentation of DAVF as a subdural hematoma (SDH) and intraparenchymal hemorrhage (IPH) is infrequent; additionally, behavioral changes are not common among these patients. We report, for the first time in our country, the case of a 23-year-old man with no history of head injury, in which a brain computed tomography (CT) scan revealed SDH and IPH with behavioral disturbances. The angiotomography showed ecstatic venous vessels, indicating the presence of a DAVF, which was later confirmed by cerebral angiography. Endovascular therapy, which followed the clinical diagnosis, resulted in satisfactory evolution two years after treatment. A review of the literature concerning cases with DAVF and behavioral disturbances is presented. DAVF may lead to cognitive impairment, behavioral changes, and dementia as a result of diffuse white matter and thalamus modifications related to venous ischemia, and it should be considered as a reversible cause of vascular dementia.
RESUMO
OBJECTIVE: To evaluate if an intraoperative cerebral regional oxygen saturation (crSO2) decrease, less pronounced than 20% below baseline (the current threshold believed to be associated with cognitive dysfunction in adults), is associated with negative postoperative behavioral changes (NPOBC) in the pediatric population after noncardiac surgeries. STUDY DESIGN: A prospective observational study was conducted with 198 children aged 2-12 years old scheduled for noncardiac procedures under general anesthesia. Intraoperatively, crSO2 was monitored with a cerebral oximeter. On postoperative day 7, the Post-Hospital Behavior Questionnaire was used to diagnose NPOBC. RESULTS: The incidence of NPOBC was 38.8%. Logistic regression analysis revealed that with every 1% reduction of crSO2 from the baseline value, the odds of developing NPOBC were 1.199 higher. Likewise, preoperative anxiety (OR 2.832, P = .006), duration of surgery (OR 1.026, P < .0001), and being between the ages of 2 and 3 years (OR 2.604, P = .048) were associated with NPOBC incidence. The multivariable logistic regression model receiver operating characteristic curve showed an area under the curve (95% CI) = 0.820 (0.759-0.881). CONCLUSIONS: During noncardiac surgeries in the pediatric population, an intraoperative decrease in crSO2 less pronounced than 20% from the baseline value is associated with negative postoperative behavior changes on postoperative day 7. The long-term implications remain to be determined, but this supports attention to crSO2 during noncardiac surgeries.

INTRODUCTION: The pathophysiology of normal-pressure hydrocephalus and the correlation with its symptomatology is not well understood. OBJECTIVE: To monitor and evaluate the enlargement patterns of the ventricular system for each ventricle and its correlation with the presenting symptoms. METHODS: Bilateral kaolin injection into the subarachnoid space overlying the cranial convexities was done in 18 adult rats. Magnetic resonance imaging was performed on an 11.7-T scanner 15, 60, 90, and 120 days after injection. Volumes of the ventricular system were measured for each ventricle and correlated with biweekly behavioral findings. RESULTS: There was a progressive increase in the ventricular volume for the lateral ventricles since day 15 in the kaolin-injected animals. There was a nonsignificant trend in volume growth for the third ventricle, but its enlargement was synchronous with the lateral ventricles. No significant change for the fourth ventricle. No symptoms were detected in the first 60 days. Association was found between the ventricular volume and locomotor changes. In addition, the odds of locomotor symptoms increased by 3% for every additional cubic millimeter of volume in the left (P < 0.001) and right (P = 0.023) ventricles, and for the total magnetic resonance imaging volume by 1% (P = 0.013). CONCLUSIONS: Expansion of the lateral ventricles maintained similar proportions over time, accompanied by a synchronous third ventricular expansion with less proportion and a nonsignificant fourth enlargement. Lateral ventricles enlarged most in those animals that were to develop late locomotor deterioration. Further research using this animal model combined with different radiologic imaging techniques, such as diffusion tensor imaging and perfusion studies, is recommended.

INTRODUCCIÓN: La encefalitis es una inflamación grave que involucra el tejido cerebral que se desarrolla de manera aguda o subaguda generalmente en menos de 4-6 semanas, presentando un alto riego de morbi-mortalidad sin un tratamiento adecuado. Las etiologías pueden ser diversas, así como también los tratamientos requeridos. La identificación de la causa constituye entonces un desafío diagnóstico. En la última década, ha habido un aumento en la identificación de formas de encefalitis asociadas con "anticuerpos de superficie neuronal". La patogénesis de las encefalitis autoinmunes radica en una respuesta inmune humoral, de anticuerpos dirigidos contra antígenos neuronales intracelulares, por un mecanismo etiopatogénico diferente, causado por una infección previa o asociado a tumores ocultos, como síndrome para neoplásico, este último más frecuente en adultos. La encefalitis por receptores de glutamato-Nmetil-D-aspartato es la forma más frecuente en niños, seguida a las encefalomielitis desmielinizantes agudas. En la clínica de los pacientes predominan cambios súbitos de conducta y trastornos del movimiento, como así también convulsiones, lo que obliga a descartar causas infecciosas, traumáticas, junto con factores tóxicos, metabólicos y neoplásicos, que a veces conlleva a una demora diagnóstica. Los métodos complementarios diagnósticos pueden ser más o menos específicos para las diferentes fases de la enfermedad. La Resonancia Magnética de cerebro puede mostrar lesiones hipertensas en región límbica o temporal, o ser normal al inicio del cuadro clínico. En la punción lumbar se puede encontrar pleocitosis linfocítica leve a moderada, aumento de la concentración de proteínas o bandas oligoclonales en aproximadamente el 50% de los casos. A nivel electroencefalográfico, un patrón Delta Brush, puede estar presente en un 30-40% de los pacientes. En la bibliografía revisada, se recomienda iniciar la inmunoterapia empíricamente. Aunque algunos pacientes experimentan una recuperación completa espontánea, esto no es frecuente y no es posible identificar a los pacientes con pronóstico favorable. La terapia de primera línea por lo general incluye esteroides, seguida o combinada, con administración de inmunoglobulina intravenosa. En caso de que el tratamiento de primera línea sea insatisfactorio, se debe iniciar tratamiento de segunda línea, con rituximab, ciclofosfamida o micofenolato, solo o en combinación. Con respecto al abordaje terapéutico, se deben esbozar estrategias adaptadas para cada paciente, considerando un enfoque menos agresivo para aquellos con un resultado generalmente mejor, teniendo en cuenta los posibles efectos secundarios versus beneficiosos de los medicamentos inmunoterápicos.

INTRODUCTION: Since the first description, immune-mediated encephalitis (EI), among them, against the anti-NMethyl-D-Aspartate (NMDAr) receptor has been increasingly recognized, being considered the most frequent immunomediated inflammatory process after Encephalomyelitis acute disseminated. OBJECTIVE: To describe trends in pediatric patients diagnosed with El. MATERIALS AND METHODS: Retrospective, observational clinical histories review was performed in the last 4 years. Eight patients with EI described. The mean age at diagnosis was 7.6 years. The delay in the diagnostic ranged from 6 to 65 days, with 26 days' average. Seven presented final EI, EI AntiNMDA el 6 and one Hashimoto El. RESULTS: Within 15 days of evolution, patients had seizures associated with behavioral changes and abnormal movements, the most frequent orofacial dyskinesias in 38%. In all cases first - line treatment was performed. Four required smafé pla resist. In three patients with second line treatment Rituximab was performed and one cyclophosphamide. The Deltha Brush Pattern was observed in a patient. In 6 of the 8 patient's complete remission (75%) was observed. There was no patient in association with occult tumors. Time tracking in an average of 2 2.8 months with a range of 4-48 months. CONCLUSIONS: Since its description to date, EI reports have been increasing. The presence of seizures associated with cognitive and behavioral changes should raise the index of suspicion and their specific study guide. Early initiation of treatment is associated directly with prognosis and evolution. (AU)

We analyzed the effect of human visitors on the behavior of a group of spider monkeys (Ateles geoffroyi) kept on a small tourist island. Although the spider monkey is a common species in zoos, there are very few specific studies on visitor effects on these monkeys. We conducted behavioral observations on the group of spider monkeys to evaluate the effect of visitors. We also used actimetry devices to measure the variations in the spider monkeys' locomotor activity associated with human presence. With regard to the effect on behavior, we found an increase in self-directed behaviors and a decrease in vocalization, both associated with human presence. Moreover, our results suggest that when people feed monkeys, there is an increase in agonistic behaviors. On the other hand, we found that changes in activity levels in response to human presence vary among individuals. We conclude that changes in spider monkeys' behavior could provide evidence of the negative effect of visitors in our study conditions. Although we discuss the differences in activity levels due to differences in social position, further research is required this topic. Our results can be used to inform management plans for this species in captivity. Improving this relationship between humans and non-human primates through tourism education programs would benefit ecotourism and therefore species conservation programs.

Owing to improvements in animal welfare, such as in nutrition, preventive medicine, and diagnostic tools, older dogs have become increasingly more prevalent than before. Unfortunately, there is an increasing number of dogs presenting behavioral changes correlated with this growth in the geriatric population. However, many of these owners consider these signs as normal for old age. This study aimed to determine the prevalence of clinical signs related with behavioral changes in the canine geriatric population admitted to the Veterinary Hospital of the Veterinary Medicine and Animal Science College of Universidade Estadual Paulista. The owners of 800 old dogs completed a questionnaire about disorientation, changes in social interaction, loss of training (house soiling), changes in the wake-sleep cycle, physical activity, memory, learning, consciousness, and perception. The results showed that the prevalence of behavioral changes in the canine geriatric population was 90.7% of dogs that presented at least one of these behavioral changes, and 22.3% with at least six changes, and with changes in physical activity (58.5%) and loss of acquired training (30.2%) being the highest percentage groups that were reported by the owners. We concluded that the prevalence of behavioral changes related with aging in the canine geriatric population was high, and that it was important to include questions about behavioral changes during regular veterinary clinical appointments to identify these clinical signs earlier and investigate the possible causes of the cognitive impairment, including neurological diseases, such as Canine Cognitive Dysfunction Syndrome.

Devido à melhora na nutrição e na medicina veterinária, há mais cães idosos do que antes. Infelizmente, acompanhando este crescimento na população geriátrica, houve um aumento no número de cães demonstrando distúrbios de comportamento e senilidade aparente. Entretanto, muitos dos proprietários têm considerado todos esses sinais decorrentes de uma inevitável velhice. O objetivo deste estudo foi obter a prevalência de sinais clínicos relacionados com alterações comportamentais na população canina idosa, atendida no Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da UNESP. Proprietários de 800 cães idosos responderam um questionário sobre desorientação, alterações na interação social, perda de treinamento (urina e/ou defeca em locais não habituais), alterações no ciclo sono-vigília, atividade física, memória, aprendizagem, consciência e percepção. Os resultados obtidos neste estudo apresentaram uma prevalência de alterações comportamentais na população canina idosa significativa, variando de 22,3% dos cães, com pelo menos seis alterações comportamentais e, chegando a 90,7% com pelo menos uma alteração de comportamento, sendo alterações na atividade física (58,5%) e perda de treinamentos adquiridos (30,2%) os grupos de maior percentual relatado pelos proprietários. Conclui-se que a prevalência de alterações comportamentais relacionadas com o envelhecimento da população canina é alta, sendo importante incluir questões sobre as alterações comportamentais durante as consultas clínicas veterinárias regulares para identificar, o mais precocemente possível, estes sinais clínicos e realizar ações para investigar as possíveis causas de déficit cognitivo, incluindo doenças neurológicas, como a Síndrome de Disfunção Cognitiva canina.

Infelizmente, acompanhando este crescimento na população geriátrica, houve um aumento no número de cães demonstrando distúrbios de comportamento e senilidade aparente. Entretanto, muitos dos proprietários têm considerado todos esses sinais decorrentes de uma inevitável velhice. O objetivo deste estudo foi obter a prevalência de sinais clínicos relacionados com alterações comportamentais na população canina idosa, atendida no Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da UNESP. Proprietários de 800 cães idosos responderam um questionário sobre desorientação, alterações na interação social, perda de treinamento (urina e/ou defeca em locais não habituais), alterações no ciclo sono-vigília, atividade física, memória, aprendizagem, consciência e percepção. Os resultados obtidos neste estudo apresentaram uma prevalência de alterações comportamentais na população canina idosa significativa, variando de 22,3% dos cães, com pelo menos seis alterações comportamentais e, chegando a 90,7% com pelo menos uma alteração de comportamento, sendo alterações na atividade física (58,5%) e perda de treinamentos adquiridos (30,2%) os grupos de maior percentual relatado pelos proprietários. Conclui-se que a prevalência de alterações comportamentais relacionadas com o envelhecimento da população canina é alta, sendo importante incluir questões sobre as alterações comportamentais durante as consultas clínicas veterinárias regulares para identificar, o mais precocemente possível, estes sinais clínicos e realizar ações para investigar as possíveis causas de déficit cognitivo, incluindo doenças neurológicas, como a Síndrome de Disfunção Cognitiva canina.

ABSTRACT: Owing to improvements in animal welfare, such as in nutrition, preventive medicine, and diagnostic tools, older dogs have become increasingly more prevalent than before. Unfortunately, there is an increasing number of dogs presenting behavioral changes correlated with this growth in the geriatric population. However, many of these owners consider these signs as normal for old age. This study aimed to determine the prevalence of clinical signs related with behavioral changes in the canine geriatric population admitted to the Veterinary Hospital of the Veterinary Medicine and Animal Science College of Universidade Estadual Paulista. The owners of 800 old dogs completed a questionnaire about disorientation, changes in social interaction, loss of training (house soiling), changes in the wake-sleep cycle, physical activity, memory, learning, consciousness, and perception. The results showed that the prevalence of behavioral changes in the canine geriatric population was 90.7% of dogs that presented at least one of these behavioral changes, and 22.3% with at least six changes, and with changes in physical activity (58.5%) and loss of acquired training (30.2%) being the highest percentage groups that were reported by the owners. We concluded that the prevalence of behavioral changes related with aging in the canine geriatric population was high, and that it was important to include questions about behavioral changes during regular veterinary clinical appointments to identify these clinical signs earlier and investigate the possible causes of the cognitive impairment, including neurological diseases, such as Canine Cognitive Dysfunction Syndrome.
