DiagnosingCharles Bonnet syndrome

There isn't a specific test for Charles Bonnet syndrome. Doctors diagnose it by:

  • talking to the person about their symptoms
  • taking a detailed medical history
  • in some cases, carrying out tests torule out other possible causes of hallucinations , such as Alzheimer's disease

If a person has vision loss and they're experiencing simple or complex hallucinations and they don't have signs of dementia or mental illness, they probably have Charles Bonnet syndrome.
