Neuropsychology Abstract of the Day: Donepezil and Aphasia
OBJECTIVE: To evaluate the efficacy of donepezil for post-stroke aphasia. METHODS: Sixty patients with acute post-stroke aphasia were divided into treatment group and a control group. All patients had been treated for secondary prevention according to the guideline. The treatment group received donepezil hydrochloride (5 mg/d) for 12 weeks. The efficacy of treatment was measured by comparing the changes of scores of Western Aphasia Battery (WAB) between baseline and 12 weeks later. RESULTS: Compared with the baseline, the changes of scores of all items of WAB and Aphasia Quotient (AQ) in both group after 12 weeks follow-up were great, however, the change of AQ was significantly greater in donepezil group (34.14 +/- 17.70)than that in control group (20.69 +/- 17.26)(P = 0.004). The patients in donepezil group also showed significant recovery in spontaneous speech, comprehension, repetition, and naming than those in control group (P < 0.05). The rate of significant improving in donepezil group was 60.0% which was significantly greater than that in control group (26.7%) (P = 0.009). CONCLUSION: There are spontaneous recovery of post-stroke aphasia within 3 months. Donepezil may facilitate the recovery in spontaneous speech, comprehension, repetition, and naming functions.
