Early indicators of primary brain tumors


  • Some patients diagnosed with nervous system diseases, mental and behavioral disorders or those being prescribed certain medications to treat those conditions may be at an increased risk of a subsequent primary brain tumor diagnosis.

Why this matters

  • Predicting persons at risk of developing a primary brain tumor is challenging due to nonspecific symptoms such as headache, dizziness and fatigue.

  • Recent evidence showed that more than 25% of patients with brain tumor had epileptic seizures for up to two years before the diagnosis but no relationship was found between a long-term history of seizures and brain tumor.

  • This is the first study to investigate early indicators of primary brain tumor after nervous system and mental and behavioral disorders using both hospital contact diagnoses and prescription medications.
