Disease Etiology (Causes)There is no definite well-known cause; however certain genetic mutations are responsible for the development of Neurocytoma of the brain.
Disease EpidemiologyThese are rare tumors that account for 0.1 to 0.5% of all brain tumors. Neurocytoma Cases are more common in people of Asian descent. They usually develop in young people between the ages of 20 and 30.
Signs and SymptomsThese Neurocytoma tumors can block or obstructs the flow of cerebrospinal fluid which generates pressures symptoms such as
- A feeling of tightness around the head
- Altered level of consciousness
- Blurred vision or inability to see in the specific area of the visual field
- loss of vision
- the sudden appearance of unstable or unsteady gait
- Loss of memory
- Weakness or paralysis of one side of the body

- Imaging tests such as X-Ray, CT-scan (computerized tomography), PET-scan (Positron emission tomography) help detect the site, size, and location of the tumor.
- Tumor biopsy and histopathological examination
