Summary
Cognitive Behaviour Therapy (CBT) using graded exposure reduced distressing visual hallucinations (VH) in schizophrenia by helping patients re-appraise them as non-threatening, leading to lasting symptom improvement.
Area of Science:
- Psychiatry
- Clinical Psychology
Background:
- Distressing visual hallucinations (VH) are common in schizophrenia, yet effective interventions are limited.
- Cognitive models suggest distress arises from threat appraisals of hallucinations.
Observation:
- A case study explored graded exposure therapy for visual hallucinations linked to phobic anxiety.
- Treatment involved 20 sessions of cognitive behaviour therapy (CBT), with 12 focused on graded exposure.
Findings:
- The patient reported reduced frequency and distress from visual hallucinations.
- These improvements were maintained at a 3-month follow-up.
Implications:
- Findings support cognitive models of VH, demonstrating exposure therapy's efficacy.
- Re-appraising hallucinations as non-threatening reduces anxiety and hallucination occurrence.
- This approach offers a potential therapeutic avenue for schizophrenia-related visual hallucinations.

In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...

01:27Hallucinogens and Psychedelics
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
