What is Hydrocephalus?
Hydrocephalus is a condition in which the normal flow of cerebrospinal fluid (CSF) is blocked. Hydrocephalus can be caused by a variety of factors, including head injuries, blockages in the ventricular system, and tumors. If left untreated, hydrocephalus can lead to brain damage and death.
Types of Hydrocephalus?
Hydrocephalus is a condition in which excess cerebrospinal fluid accumulates in the brain. Types of hydrocephalus include primary (hereditary), secondary (acquired), and tertiary (non-hereditary).
Primary hydrocephalus is the most common type and occurs when there is a mutation in the SCN9A gene. This gene produces a protein that helps control the movement of CSF in the brain. When this gene is mutated, too much CSF builds up in the brain and results in hydrocephalus.
Secondary hydrocephalus is caused by a problem with the SCN9A pathway that leads from the ventricles (large cavities inside the skull) to the brain. This pathway can become blocked, leading to excess CSF accumulation. Secondary hydrocephalus can be caused by several things, including head injury, tumor, or infection.
Tertiary hydrocephalus is rare and usually occurs as a result of aging. This type of hydrocephalus is caused by abnormalities in the arachnoid mater a protective layer that covers the brain and spinal cord.
Symptoms of Hydrocephalus?
Hydrocephalus is a medical condition in which the water content of the brain exceeds the normal limit. Excess water can cause damage to the brain and lead to symptoms. Hydrocephalus can occur at any point in life but is most commonly diagnosed in infants and young children. Symptoms may include difficulty walking, seizures, slow development, and coma. Treatment typically includes surgically removing the excess water from the brain or installing a shunt to drain it.
