RESUMO
PURPOSE: Hydrocephalus is a multifactorial neurological disorder and one of the most common neurosurgical conditions characterized by excessive cerebrospinal fluid (CSF) accumulation within the brain's ventricles. It can result in dilatation of the ventricular system caused by the inadequate passage of CSF from its point of production within the ventricles to its point of absorption into the systemic circulation. Recent findings on the genetics and molecular studies of hydrocephalus have the potential to improve treatment and quality of life. METHODS: Review of literature on the novel studies of the pathogenesis of hydrocephalus. CONCLUSION: Molecular studies on the pathogenesis of hydrocephalus have provided a means to improve the treatment and follow-up of patients with hydrocephalus.
