Charles Bonnet syndrome (CBS) affects people with partial or total vision loss, causing them to experience visual hallucinations. These hallucinations can range from simple patterns to vivid scenes, such as faces, animals, or landscapes. People with CBS are usually aware that these images aren’t real and the hallucinations don’t involve other senses like sound, smell, or touch.

Watch our video with Dr Amit Patel who describes CBS in more depth

What causes CBS?

CBS occurs when the brain fills in missing visual information due to reduced input, commonly after a deterioration in sight. It affects about one in five adults with sight loss, especially older adults. Though CBS can lessen over time, it can persist intermittently for years.

Managing CBS

Discussing symptoms openly with healthcare professionals can help understand symptoms. While there is no cure, knowing CBS is not a mental health issue offers reassurance, making symptoms easier to manage. Support groups and shared experiences can also provide relief and help reduce anxiety.

Five hints to help manage hallucinations:

  1. Stare straight at the hallucination. Looking directly hallucination can sometimes make it fade.
  2. Move your eyes. Look from left to right every second for 15–30 seconds, without moving your head. Repeat a few times if needed.
  3. Stand up and move about. Moving to a different room, or simply standing up can sometimes make them disappear.
  4. Change what you're doing. Hallucinations often appear when you’re still and unoccupied. Turning on the TV or radio can help.
  5. Reach out and touch it. Try touching the hallucination or brushing it away with your hand.
