Frequently asked questions

Find answers to frequently asked questions about Parkinson’s disease–related hallucinations and delusions and NUPLAZID.

Are hallucinations and delusions common in people with PD?

  • A hallucination means seeing, hearing, or experiencing things that others don’t

  • A delusion means believing things that aren’t true

  • Hallucinations may be described as:

    • Seeing things that others don’t, such as people, either living or deceased, animals, or objects

    • Hearing things that others don’t, such as hearing sounds, music, or voices

    • Smelling things that aren't there, like unusual odors

    • Feeling something that isn't there, like something touching or moving on the skin

    • Tasting something that isn't there, like experiencing an unusual taste in the mouth

  • Delusions may be described as:

    • Paranoia, such as believing people are talking to you or trying to access your money

    • False beliefs, such as fears of your loved ones stealing from you, or loved ones putting you in harm's way

    • Jealousy, such as believing a significant other is having an affair

    • Beliefs that insignificant remarks or statements refer to you (eg, walking into a room of people laughing and assuming they are laughing at you)

  • Hallucinations and delusions are the most common symptoms of psychosis associated with PD
  • Currently there is no clear understanding of the exact cause of PD–related hallucinations and delusions

  • However, these symptoms are thought to be caused by the following:

    • A side effect of dopamine therapy. Hallucinations and delusions may be a side effect of common PD medications (called dopaminergic therapies). These medications increase dopamine levels in the brain, helping improve motor symptoms in patients with PD. However, increasing dopamine levels may also cause changes that lead to hallucinations and delusions

    • The natural progression of Parkinson’s disease. Hallucinations and delusions may be caused by changes in the brain that occur naturally as PD progresses—regardless of whether or not you take any medications to increase your dopamine levels

  • PD–related hallucinations and delusions typically occur in the later stages of PD, 10 or more years after initial diagnosis
  • It’s important to speak to a healthcare provider if you or your loved one think you may be experiencing hallucinations or delusions

  • PD–related hallucinations and delusions may get worse over time, and people who experience these symptoms may not have the ability to identify whether or not what they're experiencing is real
