How common is psychosis?
At any one time, between 100 000 and 500 000 people in the UK have problems serious enough to call schizophrenia. About the same number have problems serious enough to call manic depression.
But psychosis is not all or nothing. Across the UK many more people have a wide range of experiences. From people who have unusual experiences now and again, to people who have them quite a lot.
It is likely that, at any one time, between 5 and 10 million people in the UK might be having some form of unusual experiences.
