Misdiagnosed for a year: Woman's brain tumor symptoms mistaken for bipolar disorder

For a year, Sarah-Jane Doherty, 24, was misdiagnosed with severe mental health issues, including bipolar disorder. Her symptoms, starting in July 2025 with extreme exhaustion, psychosis, and hallucinations, were not resolved by antipsychotic medication. During this period, she also experienced vision problems. In June 2026, a debilitating headache and electric shock sensations prompted an A&E visit.

Scans at Doncaster Royal Infirmary revealed a golf ball-sized brain tumor, suspected to be a Grade 2 Glioma. This diagnosis occurred in June 2026. The antipsychotic medication had been masking some of her key symptoms, including potential seizures presenting as electric shocks. Sarah-Jane is now preparing for extensive brain surgery, with the grade of her tumor to be confirmed post-biopsy during the procedure.

She has since shared her experience on TikTok to raise awareness about brain tumor symptoms and encourage others to seek second opinions. Doherty emphasizes the importance of prioritizing one's health and not dismissing unusual symptoms, especially when they might be incorrectly attributed to mental health conditions. She is supported by her family as she faces her upcoming surgery.
