schizophrenia

Schizophrenia is a serious brain condition in which a person's sense of what is real comes apart from the world other people share. Imagine a radio that mostly works, but every so often it picks up voices from a station that isn't really broadcasting, scrambles the signal, or convinces the listener that the static is a secret message meant just for them. Someone with schizophrenia may hear voices no one else can hear (a hallucination), hold firm beliefs that are not true and cannot be argued away, such as being spied on or controlled (a delusion), and have thoughts and speech that jump around or stop making sense to others (disorganized thinking). It is not a 'split personality,' despite the name, and it is no one's fault — it is an illness of how the brain processes and filters information.

These dramatic symptoms, called psychosis, often come in episodes, while quieter, longer-lasting changes can also appear: pulling away from people, losing motivation, flat emotion, and trouble with memory and focus. Schizophrenia usually first shows up in the late teens or twenties, and researchers think it grows out of a mix of genes and life experiences that nudge brain development off course, along with imbalances in chemical messengers — especially dopamine, the signal involved in attention and reward. There is no cure yet, but medicines that calm an overactive dopamine system, together with therapy and steady social support, can quiet the worst symptoms and help many people live full lives. Early treatment tends to lead to better outcomes.
