This excellent Horizon programme (BBC2) follows people living with voices, hallucinations and paranoia to explore the causes.
For hundreds of years, psychiatry has treated voices and hallucinations as an enemy – regarding them as ‘insanity’ or ‘madness’ and seeing them as something to be quashed and even frightened of. But today, new scientific and psychological insights into how the brain works are leading to a radical rethink on what such experiences are – and how they should be treated.
