The symptoms depend on the cause of the blockage, the person's age, and how much brain tissue has been damaged by the swelling. [11] Hydrocephalus ex vacuo is a condition in which there is ventriculomegaly due to loss of brain volume which then results in a subsequent increase in CSF. [19]

Walker–Warburg syndrome (WWS), also called Warburg syndrome, Chemke syndrome, HARD syndrome (Hydrocephalus, Agyria and Retinal Dysplasia), Pagon syndrome, cerebroocular dysgenesis (COD) or cerebroocular dysplasia-muscular dystrophy syndrome (COD-MD), [1] is a rare form of autosomal recessive congenital muscular dystrophy.

Blockage of the aqueduct can lead to hydrocephalus, specifically as a common cause of congenital and/or obstructive hydrocephalus. [ 1 ] [ 2 ] The aqueduct of Sylvius is the channel which connects the third ventricle to the fourth ventricle and is the narrowest part of the CSF pathway with a mean cross-sectional area of 0.5 mm 2 in children and ...
Normal pressure hydrocephalus (NPH), also called malresorptive hydrocephalus, is a form of communicating hydrocephalus in which excess cerebrospinal fluid (CSF) builds up in the ventricles, leading to normal or slightly elevated cerebrospinal fluid pressure.
Macewen's sign or Macewen sign (/ m ə ˈ k j uː ə n / mə-KEW-ən) is a sign used to help to diagnose hydrocephalus [1] (accumulation of excess cerebrospinal fluid) and brain abscesses. Tapping the skull near the junction of the frontal, temporal, and parietal bones will produce cracked pot sound. Positive test is indication of separated ...
Low-pressure hydrocephalus (LPH) is a condition whereby ventricles are enlarged and the individual experiences severe dementia, inability to walk, and incontinence – despite very low intracranial pressure (ICP). [1] Low pressure hydrocephalus appears to be a more acute form of normal pressure hydrocephalus. If not diagnosed in a timely ...
Onset of symptoms are less likely to be present during adulthood in most patients. Younger children generally have a substantially different presentation of clinical symptoms from older children. Younger children are more likely to have a more rapid neurological degeneration with profound brainstem dysfunction over several days. [citation needed]
