Doctors' error: how baldness nearly cost a man his life and sight

54-year-old Jason Brewerd spent years unsuccessfully treating sudden hair loss, which doctors misdiagnosed as alopecia. The real cause turned out to be a 4.6 cm brain tumor, only discovered in 2024 after an emergency hospitalization. The seven-hour surgery damaged his pituitary gland, causing strabismus and memory lapses. After returning to the UK, hormone therapy partially restored his vision and concentration, but his hair did not grow back.

54-year-old Jason Brewerd spent years unsuccessfully trying to stop sudden hair loss, attributing it to age and stress. The first bald patches appeared on his scalp and beard in 2020. Dermatologists in South Africa, where the family then lived, unanimously diagnosed alopecia areata, but treatment yielded no results. In 2022, Jason, his wife Marianne, and son Ashton moved to Alicante, Spain, seeking qualified help, but the true cause remained hidden for another two years. In January 2024, the man woke up with an unbearable headache. An emergency department MRI revealed a benign 4.6 cm brain tumor near the pituitary gland, pressing on the optic nerve and threatening blindness. The February surgery, planned for three hours, lasted seven due to bleeding that damaged the pituitary gland. The postoperative period required weeks in intensive care; strabismus and severe short-term memory lapses developed. In March 2025, the family returned to the UK, to Cambridgeshire, where treatment at Addenbrooke's Hospital corrected his hormonal balance. His concentration returned, daytime sleepiness disappeared, vision partially recovered, but the hair on his head and face did not regrow due to irreversible pituitary damage.
