Hallucinations and Delusions More Common than Thought

Hearing voices and seeing things (that others cannot) impacts about
five percent of the general population at some point in their lives
according to Professor John McGrath of the Queensland Brain Institute.
Have you ever heard voices that others cannot hear? Say, your name called when no one is around?
Or, have you seen something that no one around you sees?
Don't panic. According to this new research out of the University of Queensland and Harvard Medical School, it turns out that about 5% of perfectly healthy, normal people have or have had a hallucination or delusion, perhaps as often as five times in a life time. This is more common in affluent countries, and in women. It only becomes a problem when it occurs frequently.
Obviously, this can impact how a writer structures a character. In fact, this phenomena could be the basis of a story, an otherwise normal person hearing or seeing something no one else experiences.
Something for you to chew while crafting your fiction.

Hallucinations and delusions in the general
population more common than previously thought.
Queensland Brain Institute researcher Professor John McGrath said the study, involving more than 31,000 people from 19 countries, was the most comprehensive ever completed.

"Of those who have these experiences, a third only have them once and another third only have two-to-five episodes across their life. These people seem to function reasonably well.
"So it's incredibly interesting that not only is hearing voices more common than previously thought, but it's not always linked to serious mental illness."
The study was a population-based survey which involved approaching randomly selected members of the community, sitting down with them and conducting a very detailed interview about their mental health.
"These people were representative of the general population, not seeking mental health assistance," Professor McGrath said.
- Auditory hallucinations are more common in women than men, and
- are also more common in people from wealthier countries.
"In particular, we are interested in learning why some people recover, while others may progress to more serious disorders such as schizophrenia," he said.
"We need to understand why it's temporary for some people and permanent for others. We can use these findings to start identifying whether the mechanisms causing these hallucinations are the same or different in both situations.
"We need to rethink the link between hearing voices and mental health -- it's more subtle than previously thought.
"While people may experience a false perception such as mistakenly hearing their name called out in public, hallucinations and delusions are quite detailed, for example hearing voices that no one else can hear or a belief that somebody else has taken over your mind.
"People should be reassured that there isn't anything necessarily wrong with them if it happens once or twice, but if people are having regular experiences, we recommend that they seek help."
