Symptoms of Charles Bonnet Syndrome
Symptoms of Charles Bonnet syndrome are unique in that they involve vivid, recurring visual hallucinations in individuals with impaired vision. What sets these hallucinations apart is that people experiencing them are fully aware that the images are not real. Recognising the symptoms of Charles Bonnet syndrome can help patients seek help early and avoid unnecessary fear or confusion.
1. Visual Hallucinations
The core symptom is seeing things that aren’t there. These can range from simple to complex:
- Simple hallucinations: Flashing lights, shapes, patterns, or geometric designs
- Complex hallucinations: People, animals, landscapes, buildings, or scenes
Hallucinations often appear in colour and can be startlingly detailed. Some people report seeing Victorian-style clothing, brick walls, or unfamiliar faces.
2. Frequency and Duration | Symptoms of Charles Bonnet Syndrome
Hallucinations may last for a few seconds or several minutes. In some cases, they continue for hours. They may occur once a day or multiple times throughout the day. Some individuals experience them for weeks or months before they fade.
3. Lack of Sound or Movement
Hallucinations in Charles Bonnet syndrome are purely visual. They do not involve sound, smell, or physical sensation. The images are usually silent and often fade away when the person blinks, moves their eyes, or changes their environment.
4. Triggers and Patterns
Certain conditions may increase the likelihood of hallucinations:
- Low light or dim environments
- Fatigue or stress
- Long periods of inactivity or boredom
- Sudden changes in lighting
5. Insight and Awareness
Unlike hallucinations caused by mental illness, individuals with Charles Bonnet syndrome understand that the images aren’t real. This awareness helps differentiate the condition from psychosis, dementia, or delirium.
6. Emotional Impact
Although the condition itself is not dangerous, the hallucinations can be distressing. Some people fear they are “losing their mind” or developing dementia. Reassurance and proper diagnosis can reduce anxiety significantly.
Identifying the symptoms of Charles Bonnet syndrome early allows patients to receive support and understand that they are not alone — and not mentally ill. Education is key to easing the emotional burden of this often-overlooked condition.
