Living with Oligodendroglioma

A brain tumor that starts in supportive brain cells and often causes seizures, headaches, and personality changes.

Understanding Oligodendroglioma

Oligodendroglioma is a brain tumor that starts in oligodendrocytes, cells that make up the supportive (glial) tissue of the brain.

These tumors can be low-grade (grade II) or high-grade (grade III, also called anaplastic). They can occur anywhere in the cerebral hemisphere but are most common in the frontal and temporal lobes. Other symptoms depend on tumor size and location. GARD lists onset as any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD says common symptoms include:

  • Seizures
  • Headaches
  • Changes in personality

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and cancer specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Alex's Lemonade Stand Foundation may keep lists of experts for this condition.
