UK researchers have discovered that passing a weak electrical current between electrodes on a person’s scalp may lead to a reduction in frequency of the visual hallucinations experienced by some people living with sight loss.
These hallucinations are caused by failing eyesight and are a normal response the brain has to the loss of vision. They’re not caused by a mental health problem or dementia.
People with Charles Bonnet syndrome are usually aware that the visions aren’t real, even if they’re vivid but can be distressing nonetheless.
There is currently no cure for Charles Bonnet syndrome but there are strategies for managing the condition, and researchers continue to look for additional approaches.
