Do you know anyone who’s schizophrenia symptoms caused their hair to turn white?

A male family member of mine was diagnosed with schizophrenia at age 25 decades ago. His hair and beard had been white for as long as I could remember, always thought he was the eldest when he was actually the youngest.

Recently, his sister got diagnosed in her late 30s. She did not have a single symptom prior. It’s been a year and her whole head turned white, when there wasn’t a single white hair before.

I saw her for the first time today in almost a year, she could barely last 5 minutes before having to leave. She’s refuses to take her meds and doesn’t believe in the diagnosis. Her brother has been on the meds for decades but still sees things.

Please keep in mind that I only know about this condition what I do from my family, it’s the first time I consider seeing communities and searching more.
