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.
