RESUMEN
The aim of this study was to develop and validate a simple, quantifiable, neurologic examination for infants between 2 and 24 months of age. The assessment consists of 37 items, divided into 3 sections. The first section includes 26 items assessing cranial nerve function, posture, movements, tone, and reflexes; the second section of 8 items documents the development of motor function, and the third section of 3 items evaluates the state of behavior. We applied this assessment to a cohort of ninety-two 12-month-old infants and forty-three 18-month-old infants, with no known perinatal risk factors. The proforma presented has been designed according to the frequency distribution of the neurologic findings in this cohort. Each item is scored individually, and a global score is the sum of all individual scores. The quantitative score enhances the value of this examination, both in clinical practice and in research settings.

Ultrasonography or computed tomography scanning of the brain was performed in 10 infants with congenital myotonic dystrophy between the age of 1 day and 2 months, and showed intracranial abnormalities in all. Ventricular dilation was diagnosed in eight (80%), subarachnoid hemorrhage in one, and white matter infarcts in one. The common finding of ventricular dilation is probably related to developmental brain abnormality dating back to fetal life, because it was already present in three infants scanned on the first day of life. Neonatal asphyxia was present in seven infants, associated with intraventricular hemorrhage in two. The relationship between these changes and mental retardation, which is a common feature in this disease, is unclear.
