Cotard's syndrome is the belief that you have died, and for sufferers it is a terrifying state. Delusions can take many forms, from widespread paranoia to a specific and singular delusion - you might think an impostor has replaced your spouse. These misbeliefs are commonly associated with schizophrenia, but they can also occur in people with brain injuries, Huntington's and Parkinson's disease and dementia. The Macquarie Centre for Cognitive Science is seeking to explain delusions by developing a model of how we all come to accept or reject beliefs. We see how this research is progressing.
