Parkinson's disease dementia (PDD) is common among patients with Parkinson's disease (PD) and follows the diagnosis of PD by at least 2 years. In fact, 40% of patients with PD have Parkinson's disease dementia and up to 80% may develop PDD over time. PDD is not Alzheimer's disease. If a person develops PDD, he or she may have trouble with solving problems, planning, or recalling information. PDD is a disease of the brain that affects memory, thinking and attention, social and daily functioning, and aspects of behavior. He or she may also have hallucinations, trouble sleeping, feel restless or depressed.
EXELON PATCH is a prescription medicine for patients with mild to moderate Parkinson's disease dementia. In a study of Parkinson's disease dementia, parkinsonian symptoms, particularly tremor, occurred, or worsened in some people taking EXELON® (rivastigmine tartrate) capsules.
Parkinson's disease dementia results from a loss of nerve cells in the brain that produce important chemicals. When these chemicals stop working in the brain, so do the functions they help to control, such as decision-making or memory.
