Cognitive Impairment and Upper Extremity Performance in COPD

Study Overview
=================
Brief Summary
-----------------
Within the scope of this study, COPD patients will be divided into two groups according to cognitive dysfunction. Pulmonary function test, COPD assessment scale, Mini-Mental State Examination and Montreal Cognitive Assessment Scale, 6 min pegboard ring test, grip strength measurement, Fatigue Impact Scale and St.George Respiratory Questionnaire will be applied to the groups.

Detailed Description
-----------------
Although the mechanism of cognitive dysfunction in COPD is not clear, the reasons focused on are; decreased oxygen use, high carbon dioxide levels, increased inflammation and oxidative stress, decreased physical activity, peripheral vascular diseases, atherosclerosis, high or low blood pressure, cerebral vasoconstriction, increased intracranial pressure, accompanying comorbidities, smoking and genetic predisposition, brain damage and exacerbations have been reported. Few studies have shown that cognitive dysfunction is associated with functional performance. There are no studies on the effect of cognitive function on upper extremity performance and mechanisms of action in COPD patients. The aim of this study is to compare upper extremity functional capacities, respiratory functions, fatigue and quality of life in COPD patients with and without cognitive function impairment. Within the scope of this study, COPD patients will be divided into two groups according to cognitive dysfunction. Pulmonary function test, COPD assessment scale, Mini-Mental State Examination and Montreal Cognitive Assessment Scale, 6 min pegboard ring test, grip strength measurement, Fatigue Impact Scale and St.George Respiratory Questionnaire will be applied to the groups.
