A Descriptive Study of Cognitive Status Three Years Following Motor Stroke
Keywords

Background. Stroke, or brain attack, is a leading cause of morbidity and mortality worldwide. In the poststroke period, intact cognition is needed to recognize dangerous situations, for problem solving, and forming new memories. Cognitive status 3 years after one particular type of ischemic stroke, motor stroke, has received minimal attention.
Material and methods. This was a descriptive study of cognitive status of 60 patients 3 years following a motor stroke.
Results. Of the patients available, 11 had died, 30 consented to a home visit and 19 were interviewed by telephone. The mean age of patients at the time of follow-up was 64 years and cognitive status was measured using three instruments. The median Mini-Mental State Examination (MMSE) score at baseline was 26.00 (interquartile range, 22.25 to 28.00) and 28.50 (interquartile range, 25.75 to 30.00) at three years. Median scores on Cognistat (The Neurobehavioral Cognitive Status Examination) at baseline was 65.00 (interquartile range, 58.00 to 73.75) and 74.00 (interquartile range, 67.50 to 79.50) at three years. The mean cognitive subscore on the Functional Independence Measure (FIMTM) at baseline was 33.43 (+ 3.28) and 26.5 (+ 13.25) at three years. There were statistically significant differences between baseline and three years on each of the three cognitive measures.
Conclusions. This study provides a rich description of the cognitive status of a group of individuals 3 years after motor stroke. Although limited by a small sample size neuroscience nurses need to be aware that cognitive status may not decline in this subtype of stroke. (PNN 2012;1(3):97-102)
