Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Dynamic Lowenstein Occupational Therapy Cognitive Assessment-Geriatric Version
Time Frame: Baseline (First assessment)
The Dynamic Lowenstein Occupational Therapy Cognitive Assessment is an occupational performance measurement battery designed to assess basic cognitive skills and visual perception in adults with neurological deficits. Consists 8 subtests: orientation, awareness, visual perception, spatial perception, praxis, visuomotor construction and thinking operations and memory. All subtests of DLOTCA-G are scored between 1 - 4 points. And higher scores indicate better cognitive performance. There is no cut-off value for Parkinson's patients.
Baseline (First assessment)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mini Mental State Examination
Time Frame: Baseline (First assessment)
The Mini Mental State Examination is a brief screening tool that provides a quantitative assessment of cognitive impairment and to record cognitive changes over time. It consists of five subscales: orientation, memory, attention and calculation, recall and language. In the evaluation of the test, scores below 15 indicate low cognitive level, scores between 15 and 26 indicate medium cognitive level, and scores of 26 and above indicate high cognitive level.
