Have you ever heard someone calling your name, but then you look around and no one’s there? Or you feel your phone vibrate, but actually, it didn’t. Then you’ve technically experienced psychosis. For most of us, it will never go further. But for people who later develop schizophrenia, it often starts like this. On this week's show, KQED Health Correspondent April Dembosky takes you inside the minds of three young people experiencing psychosis. They describe how it crept up on them, how it took hold, and how new treatments helped them rewire their thoughts. But also, how insurance companies won’t pay for the full package of care.
