Hallucinations and Delusions

An abstract multi-colored brain image

Hallucinations and delusions are collectively referred to as psychosis.

Visual hallucinations are the most common type of hallucination. In a visual hallucination, someone sees things that are not actually there. There can also be auditory and olfactory hallucinations. Often hallucinations are not alarming to the person experiencing them.

Delusions are when there is an alternative view of reality: an entire irrational story is created. Paranoia is a common type of delusion. Capgras delusions are a specific type of delusion where the person believes that a spouse, adult child, or other family member has been replaced by an imposter.

 

If you are a caregiver to someone who is experiencing hallucinations or delusions, it's important to discuss these symptoms with the movement disorder specialist or neurologist.  These symptoms could be caused by medications, infections, or metabolic imbalances.  See our guidance on preparing for an appointment with the doctor.
