Judith Potts writes in the Daily Telegraph:
One day in 2007 my late mother – then a sprightly 93 year old – said to me “I do wish these people would get off my sofa. They sit there all day and only go if I tap them on their heads or shoulders.” She and I were the only people in the room.
I was extremely alarmed when she described her “visions”. Not only were there the faceless people on her sofa but other apparitions which peppered her daily life and had been doing so for about 18 months. I suspect she decided to confide in me at that point because some of the “visions” were becoming difficult to tolerate. Up to that moment, she was terrified – not of the visions, but of losing her sanity.
Listening to her descriptions of gargoyle-like creatures evading capture, an Edwardian funeral procession – complete with plumed horses, carriages and clergy in red cassocks – and an urchin hopping from room to room, I was perplexed. I drove home pondering how to help, picking up a newspaper on the way. To my enormous surprise, the paper carried an article about exactly my mother’s experience and I learned that the condition had a name – Charles Bonnet Syndrome.
With this lucky discovery, I began to do some research and was able to reassure my mother that she was not alone – in fact it is reckoned that there might be two million people in the UK suffering from this condition….
The medical term for mum’s “visions” is Visual Hallucinations and they occur when there is partial or total loss of vision, caused by macular degeneration, diabetic retinopathy or cataracts. The brain, which controls sight through the eye, fills in the blank spots with stored images. These can be from real life, from film or television, from books or radio. While these visual hallucinations tend to happen to people as they age, anyone who experiences loss of vision can be affected, even children.
Interesting. So basically visual tinnitus.
