Abstract
Background: Stroke is one of the major causes of physical and mental disability among people. Vascular cognitive impairment (VCI) represents a wide spectrum from mild cognitive impairment to dementia following cerebrovascular disorder that is resulting in either ischemic or hemorrhagic stroke.
Purpose of study: This study was conducted to investigate the difference in cognitive functions’ affection following ischemic versus hemorrhagic stroke.
Subjects: 75 subjects were enrolled in this study, 25 healthy subjects and 50 stroke patient (25 ischemic and 25 hemorrhagic stroke patients) of both sexes with age range between 45 and 55 years old, duration of illness was between 6 to 12 months and years of education of patients and subjects participated in this study was at least nine years. The patients were selected from outpatient clinic, Faculty of Physical Therapy, Cairo University, Egypt.Subjects were classified into three groups: GA (25 healthy subjects), GB (25 ischemic stroke patients) and GC (25 hemorrhagic stroke patients).
Methods: Both of healthy subjects and stroke (ischemic and hemorrhagic) patients received cognitive assessment via Montreal cognitive assessment scale (MOCA) and Rehacom system as four categories were assessed which are figural memory, attention concentration, reaction behavior and logical thinking; each category was assessed for 30min.
Results: This study results showed that there was a significant difference between the results of MOCA scale and Rehacom system among the three groups , with (P ≤ 0.05). Also, there was a significant difference between GB (ischemic stroke) and GC (hemorrhagic stroke).
Conclusion: on the basis of the present data , it can be concluded that healthy subjects have better preserved cognitive functions in comparison with stroke patients (either ischemic or hemorrhagic stroke) , based on MOCA scale results , deterioration in cognitive functions in hemorrhagic stroke was greater than in ischemic stroke , based on Rehacom System results , figural memory and logical thinking were more affected in patients with hemorrhagic stroke in comparison with ischemic stroke patients and reaction behavior and attention concentration were more affected in patients with ischemic stroke in comparison with haemorrhagic stroke patients .
