Positive Symptoms Schizophrenia: Hallucinations and Delusions

55
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Hallucinogens 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.

Visual Agnosia01:12

Visual Agnosia

190
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Area of Science:

  • Psychology
  • Psychiatry
  • Clinical Psychology

Background:

  • Visual hallucinations (VH) are prevalent in psychotic illnesses, causing significant distress and disability.
  • Current treatments, including cognitive behavioral therapy (CBT), have limited success in reliably reducing VHs.
  • Problematic mental imagery, similar to VHs, is often linked to negative affect and improves with imagery-focused interventions.

Purpose of the Study:

  • To investigate the feasibility, safety, and effectiveness of a 10-session imagery-focused therapy for visual hallucinations.
  • To explore the potential of an imagery-focused approach as a more effective treatment for VHs.

Main Methods:

  • A multiple baseline case series design was employed with 11 participants.
  • The intervention consisted of a 10-session imagery-focused therapy tailored for visual hallucinations.
  • Data were collected at multiple baselines, mid-therapy, post-therapy, and at a 3-month follow-up.

Main Results:

  • The therapy demonstrated good feasibility, safety, and acceptability, with high attendance and positive feedback.
  • A majority of clients experienced significant reductions in VH severity and distress.
  • Medium to large effect sizes were observed for both full-scale and weekly measures.

Conclusions:

  • An imagery-focused therapy approach shows promise for treating visual hallucinations.
  • The findings support the potential benefit of this approach, particularly given the role of mental imagery in VHs.
  • Further rigorous clinical trials are recommended to confirm these preliminary findings.
