From the Research

Charles Bonnet syndrome (CBS) is a condition characterized by complex visual hallucinations in individuals with visual impairment, which can be understood as a form of delusion that is distinct from psychotic disorders. The provided evidence does not directly address Charles Bonnet syndrome, but it offers insights into the nature of delusions in general. According to 1, delusions are complex phenomena that emerge from a dynamic interplay between subpersonal, personal, interpersonal, and sociocultural processes. This understanding can be applied to CBS, where visual hallucinations may serve as a coping mechanism for individuals dealing with significant visual loss. Key aspects of CBS delusions include:

  • Complex visual hallucinations that can range from simple shapes to detailed images of people, animals, or scenes
  • These hallucinations are typically vivid and detailed, and can be distressing or comforting to the individual
  • CBS is distinct from psychotic disorders, as it is not associated with the same level of cognitive impairment or disorganized thinking
  • The condition is more common in older adults with significant visual impairment, and can be exacerbated by social isolation, sensory impairments, or underlying medical conditions
  • Early intervention and support can improve outcomes, as individuals with CBS may benefit from counseling, cognitive behavioral therapy, or other forms of psychological support to cope with their visual hallucinations. It's essential to approach individuals with CBS with empathy and understanding, rather than directly challenging their experiences, and to provide a thorough physical examination to rule out other medical conditions that may contribute to their symptoms.
