Parkinson’s Disease Dementia

Talk to your doctor if you or someone close to you has symptoms of Parkinson’s Disease dementia.

Parkinson’s disease dementia (PDD) is a decline in thinking, reasoning and behaviour that eventually affects many people with Parkinson’s disease.

PDD is linked to tiny deposits in the brain of Lewy bodies, or alpha-synuclein protein. Ask your doctor about this protein.

Factors that increase the risk of Parkinson’s Dementia

At the time of a Parkinson’s diagnosis, the following factors may indicate a higher future risk of dementia:

  • Older age
  • Greater severity of motor symptoms – unstable posture, freezing in mid-step, shuffling, problems with balance and falling
  • Mild cognitive impairment
  • Hallucinations in a person who doesn’t yet have other dementia symptoms
  • Excessive daytime sleepiness
