Hydrocephalus ex-vacuo occurs when a stroke or injury damages the brain and brain matter actually shrinks. The brain may shrink in older patients or those with Alzheimer's disease, and CSF volume increases to fill the extra space. In these instances, the ventricles are enlarged, but the pressure usually is normal.

Signs and symptoms gradually develop; they may include memory loss, speech difficulties, apathy, difficulties with Hydrocephalus is an abnormal build-up of cerebrospinal fluid(CSF) within and around the brain, which can due to excess fluid production, obstruction to its flow, and inadequate absorption[1] If left untreated, the excess fluid can cause increase the pressure put on the skull and brain, which can be damaging[2]. Furthermore, hydrocephalus can be caused by a disturbance in the drainage of cerebrospinal fluid.

Insights into origins of idiopathic normal pressure hydrocephalus, NPH Nasal cerebrospinal fluid leakage, CSF rhinorrhea, is a rare cause of runny nose.

However, the cause is often not known. Hydrocephalus present from birth Congenital hydrocephalus is when a baby is born with excess fluid in their brain. It can be caused by a condition such as spina bifida, or an infection the mother develops during pregnancy, such as mumps or rubella (German measles). In these cases, hydrocephalus may be caused by: inherited genetic abnormalities that block the flow of CSF developmental disorders such as those associated with birth defects in the brain, spine, or spinal cord complications of premature birth such as bleeding within the ventricles Hydrocephalus has many different causes. Some people are born with the condition, while others develop it during their lives. Normal pressure hydrocephalus (NPH) is a type of hydrocephalus that Se hela listan på emedicine.medscape.com underlying cause of hydrocephalus.

Jan 16, 2020 Common causes of congenital hydrocephalus are: Aqueductal Stenosis; Neural Tube Defects; Arachnoid Cysts; Dandy Walker Syndrome; Chiari 

Congenital hydrocephalus is caused by a complex interaction of genetic and environmental factors during fetal development. One of the most common causes of congenital hydrocephalus is “aqueductal stenosis” (a narrowing of the aqueduct of Sylvius, a cerebral aqueduct). Another common cause of hydrocephalus is a neural tube defect (NTD). Hydrocephalus merely denotes an increase in the volume of CSF and thus of the cerebral ventricles (ventriculomegaly).. Although hydrocephalus is typically referred to as either being "obstructive" or "communicating", this can lead to confusion as to the underlying cause of ventriculomegaly as the terms are referring to different aspects of the underlying pathophysiology (namely "why" and "where").

A stroke or traumatic injury causes damage to the brain, which may cause brain tissue to shrink. Premature infants  Both types of hydrocephalus can cause increased pressure within the brain.
