What is meningioma?
Meningioma is a type of brain tumour that arises from the meninges, the layers of tissue that cover the brain and spinal cord. While the majority of meningiomas are benign (non-cancerous), they can vary in their growth rate and potential impact on surrounding neurological structures.
What are the symptoms of meningioma?
The symptoms of meningioma largely depend on the tumour's size and location. Common symptoms include:
- Headaches
- Seizures
- Visual disturbances
- Hearing loss or ringing in the ears
- Memory loss
- Personality changes
- Weakness in arms or legs
- Difficulty speaking
What causes meningioma?
The exact causes of meningiomas are not well understood. However, certain factors have been identified that may increase the risk of developing meningiomas:
- Gender. Women are more likely to develop meningiomas, possibly linked to hormonal factors.
- Radiation exposure. Exposure to ionising radiation is a known risk factor.
- Genetics. Family history of meningiomas may increase risk.
What are the complications and related diseases for meningioma?
While most meningiomas grow slowly, their location and size can lead to serious complications, including:
- Increased intracranial pressure
- Hydrocephalus (accumulation of fluid in the brain)
- Impaired brain function
- Permanent neurological damage
- Rarely, malignant transformation into cancerous forms
How do you prevent meningioma?
There are no guaranteed methods to prevent meningiomas. Minimising exposure to known risk factors such as ionising radiation might reduce risk. Regular check-ups can help in early detection and management of the condition, especially for those with a family history of brain tumours.
