Charles Bonnet Syndrome

Common Name(s)

Charles Bonnet Syndrome

Charles Bonnet syndrome is a condition that causes individuals with vision loss to see objects, patterns or images that do not exists (visual hallucinations). These individuals are aware that these hallucinations are only illusions, not reality.  This disorder is likely caused by the brain continuing to interpret images even in their absence.  Hallucinations are more likely to occur when the individual is awake, alone, in dim light, physically inactive, or lacking distractions.  The brain usually adjusts after about a year and hallucinations begin to go away.
