Impact of anxiety on verbal and visuospatial working memory in patients with acute stroke without severe cognitive impairment.

Background: Working memory is the most impaired cognitive domain in the acute phase of stroke. In a context where anxiety is highly prevalent, close attention must be paid to anxiety which could mimic mild to moderate working memory impairments. This is the first study to assess the contribution of state anxiety (the currently experienced level of anxiety) to the working memory (verbal, visuospatial) in patients with first-ever acute stroke without severe cognitive impairment.

Paradoxical state anxiety and working memory in a patient with acute stroke.

Objective: In view of the negative impact of anxiety on working memory, we induced anxiety in 26 patients with acute stroke and 33 healthy controls, and studied how the anxiety affected their emotional reactivity and how the reactivity affected their verbal and visuospatial working memory. We compared the overall findings with those in 1 of our patients (C.B.
