Can a brain scan detect mental illness?

Can a brain scan indicate that someone is susceptible to dementia or Alzheimer's?

Best Answer

Psychiatrists claim that brain scans now show brain changes that “prove” mental disorders, such as schizophrenia and depression, are brain based.

There is no scientific evidence to prove this: it remains what the “fine print” in the studies tell you: “suggests,” “may” and “it is hoped.”
