What should you know about high glioma?

Gliomas begin in glial cells, which support nerve cells in the brain and spinal cord. High-grade describes tumour features seen on imaging and, when available, under the microscope, such as cells that divide actively or invade nearby brain tissue. The grade is not determined by symptoms alone. MRI helps show the tumour's position and effect on surrounding tissue, while a biopsy or surgical sample can provide details that guide treatment.

Symptoms vary with location and may include new seizures, headaches, weakness, speech changes, memory problems, or altered balance. These symptoms can also arise from non-cancerous conditions, so they require clinical assessment rather than self-diagnosis.

Arrange review with a neuro-oncology or neurosurgical team. Bring scan reports, medicine lists, and information about seizures or changes in function. Treatment may involve surgery to remove as much tumour as safely possible, followed by radiotherapy and medicines selected for the tumour's pathology and molecular findings. Ask about rehabilitation for movement, speech, thinking, or daily activities.

Seek emergency help for a first seizure, a seizure lasting longer than expected, sudden weakness, new trouble speaking, severe drowsiness, repeated vomiting, or a rapidly worsening headache. Do not drive after a seizure unless your medical team confirms that it is safe and legal to do so.

Ask where the tumour is located, whether tissue sampling is safe, what the pathology shows, and which treatment aims are realistic. Ask how treatment could affect concentration, movement, speech, and independence, and who to contact if a symptom changes.
