Delusions

Delusions are false beliefs held firmly in the face of overwhelming evidence to the contrary. They are typically symptoms of severe psychological disorders, such as schizophrenia and bipolar disorder, but may also be seen in individuals with dementia and other neurologic conditions. Delusions can take many forms, such as paranoia, grandiosity, erotomanic delusions, religious delusions, and nihilistic delusions. They can affect a person's functioning and ability to participate in everyday activities. The ability to identify and treat delusions is a critical skill for mental health professionals, as they can significantly improve the quality of life of those affected.
