Area of Science:

Neuroscience
Neurology
Psychiatry

Background:

Poststroke irritability (PSI) is a frequent complication following stroke.
PSI negatively impacts survivors' quality of life, social interactions, and caregiver well-being.

Purpose of the Study:

To evaluate the clinical, neuropsychological, and MRI correlates of PSI.
To examine the 15-month progression of PSI in stroke survivors.

Main Methods:

Prospective cohort study of 285 stroke survivors and their caregivers.
Assessments at 3, 9, and 15 months post-stroke, including the Neuropsychiatric Inventory (CNPI).
MRI scans (diffusion-weighted imaging) within 1 week of stroke; logistic regression and ANCOVA for data analysis.

Main Results:

This section is not available in the provided abstract.

Conclusions:

This study is the first MRI investigation into PSI.
Findings will elucidate the association between specific brain lesions (orbitofrontal cortex, amygdala, etc.) and PSI risk.
