Hydrocephalus (Communicating)

Hydrocephalus (Communicating) is a condition where excess cerebrospinal fluid (CSF) builds up in the brain's ventricles, causing increased pressure. This affects the central nervous system, particularly the brain, by compressing brain tissue and disrupting normal function. Unlike other types, communicating hydrocephalus occurs when CSF can still flow between ventricles but is not properly absorbed into the bloodstream. This leads to symptoms such as headache, balance problems, and cognitive difficulties. The condition can develop gradually and may affect people of all ages, impacting their daily activities and overall health.

Hydrocephalus (Communicating) is characterized by an abnormal accumulation of cerebrospinal fluid (CSF) within the ventricular system due to impaired absorption at the level of the arachnoid villi, without obstruction of CSF flow between ventricles. This results in ventricular enlargement and increased intracranial pressure. Common causes include subarachnoid hemorrhage, meningitis, or trauma that disrupts CSF absorption. The condition is clinically significant because it can lead to neurological deficits, including gait disturbance, urinary incontinence, and cognitive decline, especially in normal pressure hydrocephalus. Diagnosis and management are critical to prevent permanent brain damage.
