Anterior And Posterior Types Of Neuropsychological Deficits In Parkinson’S Disease: A Subgroup Classification Of Cognitive Outcome, Megan M. Risi

Honors Program Theses and Projects

Individuals with Parkinson’s disease (PD) exhibit cognitive deficits. Recent studies suggest there are distinct cognitive profiles of PD characterized by deficits in abilities that are dependent upon anterior versus posterior areas of the brain. While anterior-based deficits are more prevalent, posterior-based deficits are more predictive of the future occurrence of dementia in PD. The purpose of the current project was to examine these cognitive profiles in more detail. Performance on six tests of anterior function and six tests of posterior function was examined in 34 non-demented PD participants and 27 healthy control participants matched for age and education. Results showed …

In healthy individuals and those with insomnia, poor sleep quality is associated with decrements in performance on tests of cognition, especially executive function. Sleep disturbances and cognitive deficits are both prevalent in Parkinson's disease (PD). Sleep problems occur in over 75% of patients, with sleep fragmentation and decreased sleep efficiency being the most common sleep complaints, but their relation to cognition is unknown. We examined the association between sleep quality and cognition in PD. In 35 non-demented individuals with PD and 18 normal control adults (NC), sleep was measured using 24-hr wrist actigraphy over 7 days. Cognitive domains tested included …
