چکیده
Consistent with the clinical focus of this volume, this chapter first acquaints the reader with basic distinctions between the clinical ‘‘brain-behavior’’ disciplines, namely neuropsychology, behavioral neurology, and neuropsychiatry. After describing the most common approaches to neuropsychological evaluation and the goals of neuropsychological evaluation in Parkinson’s disease (PD), the chapter highlights the cognitive alterations most frequently accompanying PD and those that occur in and differentiate dementias seen in PD from other neurodegenerative conditions. A discussion of the impact of emotional comorbidity on cognition makes clear the importance of treating anxiety, depression, and psychiatric symptoms in optimizing the afflicted person’s functioning and quality of life. Both medical and surgical treatments, the latter enjoying a renaissance after a protracted, relative absence from the treatment armamentarium after the introduction of levodopa, have the potential to impact cognition. Only a sparse literature devotes itself to treatment-related neurobehavioral complications and less frequent improvements. The chapter concludes with a brief comparison of the most common cognitive alterations

متن کاملDementia with Parkinson’s disease Clinical diagnosis, neuropsychological aspects and treatment
Dementia with Parkinson’s disease represents a controversial issue in the complex group of alphasynucleinopathies. The author acknowledges the concept of a “continuum” between Parkinson disease’s (PD), Lewy body dementia (LBD), and dementia in Parkinson’s disease (PDD). However, the practicing neurologist needs to identify the phenotypic signs of each dementia. The treatment and prognosis are d...
