Behavioral problems in stroke rehabilitation patients: A prospective pilot study

Area of Science:

• Neurology
• Psychiatry
• Rehabilitation Medicine

Background:

• Stroke rehabilitation is complex and can be impacted by patient behavior.
• Previous experience suggests various behavioral issues arise post-stroke.
• A systematic evaluation of these problems is needed to understand their impact.

Purpose of the Study:

• To determine the frequency and significance of behavioral problems in stroke rehabilitation patients.
• To investigate associations between specific behavioral issues and neurological variables.
• To assess the correlation between behavioral problems and rehabilitation outcomes.

Main Methods:

• Prospective pilot study involving 32 patients undergoing post-stroke rehabilitation.
• Evaluation of depression and other behavioral problems including somnolence, irritability, anxiety, confusion, delusions, denial of deficit, impulsivity, inappropriate sexual behavior, and pain.
• Analysis of associations between behavioral problems, neurologic variables, and rehabilitation outcomes.

Main Results:

• Depression was identified in 31% of patients.
• Other behavioral problems were present in up to 41% of the study cohort.
• Significant associations were found between somnolence and left hemisphere infarct, the number of behavioral problems and rehabilitation outcome, and specific behavioral problems with neurologic variables.

Conclusions:

• Behavioral problems, beyond depression, are frequently observed in stroke survivors.
• These behavioral issues correlate with specific neurological variables.
• Identified behavioral problems can significantly hinder stroke rehabilitation progress and outcomes.
