Escitalopram promotes recovery from hand paresis in cortical sensori-motor stroke: a randomized, double-blind, placebo-controlled longitudinal study.

PMID 41620762WHAT IT FOUND
Escitalopram plus occupational therapy improved fine finger dexterity and brain activation patterns more than placebo plus therapy over nine months in acute stroke.
However, the study was tiny, so this is a signal for larger trials, not a reason to change practice.
Key findings
01The escitalopram group showed significant improvement in finger gaiting between three and nine months, and in card-turning speed between baseline and three months, while the placebo group did not show significant changes in these specific fine-motor tasks.
02At three months, the escitalopram group showed normalized brain activity in motor control areas compared to the placebo group, but by nine months, the placebo group showed increased activation in the thalamus, suggesting compensatory effort.
03All patients received occupational therapy for hand paresis during the first three months, meaning the treatment effect cannot be separated from the concurrent therapy.

What it does not show
The study is severely underpowered, analyzing only 21 patients against a planned sample of 50, which limits the reliability of the findings. The patient cohort was highly selected, excluding those with aphasia or severe cognitive issues, so results do not apply to the broader stroke population. All patients received occupational therapy, making it impossible to separate the effect of the drug from the effect of the therapy. The primary outcome measure (finger gaiting) showed baseline imbalances between groups that complicated interpretation, requiring post-hoc statistical corrections. The study duration was limited to nine months, and the effects on brain activation were transient or divergent at different time points.

The easy way to misread this
Do not interpret the positive findings as evidence that escitalopram should be routinely prescribed for hand paresis. The study was a pilot with only 21 patients, which was underpowered for its planned sample size, and all participants received occupational therapy, so the drug's specific contribution cannot be isolated from the therapy.
