Overview
Epidemiology and Demographics
- People can develop astrocytomas at any age.
- The low-grade type is more often found in children or young adults, while the high-grade type are more prevalent in adults.
- Astrocytomas in the base of the brain are more common in young people and account for roughly 75% of neuroepithelial tumors.
Age
Subependymal Giant Cell Astrocytoma
- Subependymal giant cell tumours are a well known manifestation of TS, affecting 5-15% of patients with the condition. They are principally diagnosed in patients under 20 years of age, but are occasionally found in older people[1].
Anaplastic Astrocytoma
Anaplastic astrocytomas occur in adulthood with peak incidence between 40 and 50 years of age, which is older than low grade astrocytomas and younger than glioblastoma.[2]
