The beautiful and extensive Understanding Psychosis and Schizophrenia: Why people sometimes hear voices, believe things that others find strange, or appear out of touch with reality... and what can help' is a report from the British Psychological Society, Division of Clinical Psychology, from late 2014 see full report
'What is Psychosis'? An introduction on psychotic disorders for caregivers, family and friends, by Jan Olav Johannessen, (president of ISPS) also an excellent primer, and includes information on how psychological developmental issues can contribute to the development of psychosis.
Psychosis Is Nothing Like a Badger Henry Gale created this animation to raise awareness concerning the signs and symptoms of Psychosis, in the hope that sufferers (and those around them) can seek help without fear, judgment, or hesitation. Having walked away from two episodes of psychosis, he felt that the beginning stages of the illness brought him the most fear and confusion. It was a hazy, in many ways unhelpful diagnosis, that was difficult to talk about - both for its stigma and lack of clarity. He is hoping that this video might help bridge that gap, giving sufferers, as well as their friends and relatives, a simple insight into how and why Psychosis affects people the way it does.
Remember, Psychosis is Nothing like a Badger.
