What Happens When Parkinson’s Leads to Dementia?

Discover how Parkinson’s Disease Dementia affects daily life

Parkinson’s Disease Dementia (PDD) refers to cognitive decline that develops in individuals with a long-standing Parkinson’s diagnosis. Not everyone with Parkinson’s will experience dementia. It typically emerges in the later stages of the disease affecting memory, attention, problem-solving, and behavior.

What to know about Parkinson’s dementia:

  • Symptoms generally appear after years of managing Parkinson’s motor symptoms
  • Affects thinking, decision-making, and daily functioning
  • Memory problems may be less prominent early on
  • Behavioral shifts like apathy, confusion, or hallucinations may develop
  • Progresses gradually and varies from person to person
  • Sometimes overlaps with Lewy body dementia

Signs of Parkinson’s Disease Dementia

Symptoms may appear slowly and build over time

The early signs of Parkinson’s dementia can be subtle, often mistaken for normal aging or medication side effects. Over time, these changes can become more disruptive, especially when paired with ongoing motor challenges.

Common signs of Parkinson’s dementia may include:

  • Slowed thinking and mental processing
  • Trouble with attention, concentration, or multitasking
  • Difficulty planning, organizing, or following steps
  • Visual hallucinations or seeing things that aren’t there
  • Mood changes including apathy, depression, or anxiety
  • Increasing forgetfulness or confusion in familiar situations
  • Shifts in behavior, such as irritability or social withdrawal
  • Poor judgment or changes in decision-making
  • Trouble with spatial awareness, reading, or interpreting visual cues
