This is an open-label study to investigate the effects of the rivastigmine patch on attention and behavior in Parkinson's disease with Dementia (PDD). Rivastigmine is an FDA approved medication used for the treatment of mild to moderate Alzheimer's Disease (AD) and dementia due to Parkinson's disease. Recently a rivastigmine patch was developed, which has shown similar effectiveness with fewer side effects and increased caregiver preference when compared to capsules for the treatment of AD, but has had poor documentation when tested in PDD. This is an open-label 12 week study where 15 subjects diagnosed with PDD (people who have known Parkinson's Disease and have mild to moderate memory and/or thinking complaints) will be treated with the rivastigmine patch at UCSF. This study also analyzes the mechanism by which the rivastigmine patch works in PDD.
Upon referral to this study, subjects will undergo screening to ensure they meet inclusion criteria. At screening, participants will undergo an interview (prior medical & psychiatric history), neuropsychological testing, and physical & neurological exam, including UPDRS to measure parkinsonian symptoms and Hachinski score to measure cerebrovascular disease. At the end of the screening visit, the neurologist will evaluate whether the participant meets PDD research criteria and will also re-review the inclusion/exclusion criteria to ensure that the participants meets criteria for the study. All participants will undergo vital signs and an ECG to ensure minimal cardiovascular risk prior to receiving rivastigmine. Appropriate lab work will also be performed to exclude other potential causes of cognitive impairment.
At baseline visits, participants will undergo a short neurological exam, an MRI scan, attention testing, and a detailed behavioral assessment, after which they will be started on a 5cm2/24hr rivastigmine patch. After 4 weeks, the dose will be increased to a recommended target dose of 9.5cm2/24hr patch. At this visit a short neurological exam will also be conducted. After 12 weeks, participants will again undergo a short neurological exam, an fMRI scan, attention testing and a behavioral assessment. Adverse events and compliance will be assessed every 2 weeks of the study.
Informants will be asked to complete questionnaires regarding the primary participant at the baseline and 12 week visits.

Alzheimer's disease (AD) is characterized by progressive cognitive decline, often associated with Behavioral and Psychological Symptoms of Dementia (BPSD). Acetylcholinesterase inhibitors (ChEi) may a...
The correct classification of non-Alzheimer's dementia is crucial to study disease mechanisms, predict disease progression and test disease-specific treatments. Brain atrophy assessment with morphomet...
Effect of acetylcholinesterase inhibitors donepezil and rivastigmine on the activity and expression of cyclooxygenases in a model of the inflammatory action of fluoride on macrophages obtained from THP-1 monocytes.
Inflammation is an important factor in the development of many diseases of the central nervous system, including Alzheimer's disease and other types of dementia. Given that acetylcholinesterase inh...
Cardiovascular risk factors are closely linked with dementia risk, but whether heart disease predisposes to dementia is uncertain.
The understanding of survival in dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) is limited, as well as the impact of these diagnoses in an ageing co-morbid population.
A carbamate-derived reversible CHOLINESTERASE INHIBITOR that is selective for the CENTRAL NERVOUS SYSTEM and is used for the treatment of DEMENTIA in ALZHEIMER DISEASE and PARKINSON DISEASE.
An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.
A medicated adhesive patch placed on the skin to deliver a specific dose of medication into the bloodstream.
Skin tests in which the sensitizer is applied to a patch of cotton cloth or gauze held in place for approximately 48-72 hours. It is used for the elicitation of a contact hypersensitivity reaction.
A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea. (From Adams et al., Principles of Neurology, 6th ed, pp1060-4)
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
Dementia describes a range of symptoms of cognitive decline. For example memory loss, problems with reasoning and communication skills, and a reduction in a person's abilities and skills in carrying out daily activities. There are about 820,000 peo...
