The PRESENCE Study - Home

We don't want to miss out on life's most precious moments.

The PRESENCE Study is evaluating an investigational treatment to test its effects on some symptoms like memory and thinking in people with dementia associated with Parkinson’s disease or Dementia with Lewy Bodies (DLB).

About Dementia with Lewy Bodies (DLB)

Dementia with Lewy Bodies is a progressive brain disorder affecting behavior, cognition, and movement.

It affects

people in the United States alone
DLB is the second most common form of degenerative dementia.
Symptoms of DLB usually involve at least two of these four features: movement disorder (possibly leading to a diagnosis of Parkinson’s disease first), changes in memory/thinking (that may be mistaken for Alzheimer’s disease), sleep disorder (such as acting out dreams), or as a neuropsychiatric issue (which can include hallucinations and behavior problems).

More research is desperately needed for this disorder and that’s why the PRESENCE Study is a big step in the right direction.


About Dementia Associated with Parkinson’s Disease (PDD)

Dementia associated with Parkinson’s disease is diagnosed if symptoms of dementia occur a year or more after the onset of motor symptoms.


0 %
of people with Parkinson's disease will develop dementia
Typically, people with Parkinson's disease that develop symptoms of dementia will do so around 10-15 years after their initial Parkinson's diagnosis.
Dementia has a worse impact on those with Parkinson's disease as compared to those with Alzheimer's disease because of the combination of motor and cognitive issues.

The PRESENCE Study is evaluating an investigational medication with the goal of improving memory and thinking in those suffering from dementia associated with Parkinson’s disease.
