Charles Bonnet Syndrome and its Characteristics

Charles Bonnet Syndrome is a condition experienced by individuals with visual impairment where they have phantom visual images or hallucinations. The hallucinations are purely visual and recognized by the sufferer as not real. They typically resemble silent movies, with vivid, colorful, and sometimes surreal scenes. The syndrome does not stem from significant cognitive impairment and does not cause dementia. The exact mechanism in the brain that drives the hallucinations is not fully understood, but it is believed to be related to deafferentation, a decrease in nerve signal input to the visual cortex.
