Galantamine administration in chronic post-stroke aphasia

Area of Science:

• Neuroscience
• Neurology
• Pharmacology

Background:

• Investigating galantamine's effect on linguistic function in chronic post-stroke aphasia.
• Analyzing factors associated with treatment response.

Purpose of the Study:

• To evaluate the efficacy of galantamine in improving language abilities in patients with chronic post-stroke aphasia.
• To identify predictors of response to galantamine treatment.

Main Methods:

• Prospective study of 45 patients (<75 years) with chronic aphasia (≥1 year).
• Galantamine administered at 8 mg/day for 4 weeks, then 16 mg/day for 12 weeks.
• Language function assessed using Western Aphasia Battery (Aphasia Quotient - AQ) at baseline and 16 weeks.

Main Results:

• Significant increase in total AQ score in the galantamine group (p=0.007), but not in the control group (p=0.308).
• Higher baseline AQ, galantamine use, and Mini-Mental State Examination (MMSE) scores were associated with improved AQ.
• Good responders showed higher education, baseline MMSE, and subcortical dominant lesions (OR 30.3; p=0.041).

Conclusions:

• Galantamine demonstrates a beneficial effect on chronic post-stroke aphasia.
• Subcortical dominant lesions independently predict a better response to galantamine.
