Stroke patients experience higher depression rates. Right-hemisphere strokes correlate with greater depression, unlike left-hemisphere strokes, with no link to physical function or lesion size.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Clinical Neurology

Background:

  • Stroke is a leading cause of long-term disability.
  • Depression is a common comorbidity following stroke.
  • Understanding the neurological correlates of post-stroke depression is crucial for patient care.

Purpose of the Study:

  • To investigate the prevalence of depression in stroke patients.
  • To examine the relationship between lesion location (hemisphere) and depression severity.
  • To explore correlations between depression and functional impairments after stroke.

Main Methods:

  • A cohort of 92 stroke patients and 30 healthy controls was assessed.
  • Depression levels were evaluated in all participants.
  • Lesion location, physical function, aphasia severity, and lesion volume were analyzed in relation to depression.

Main Results:

  • Stroke patients exhibited a significantly higher frequency of depression compared to controls.
  • Patients with right-hemisphere lesions reported more severe depression than those with left-hemisphere lesions.
  • No significant correlation was observed between depression severity and the degree of impaired physical function, aphasia, or lesion volume.

Conclusions:

  • Depression is more prevalent in stroke survivors than in the general population.
  • Right-hemisphere brain damage is associated with increased depression risk post-stroke.
  • Functional deficits and lesion characteristics do not appear to predict depression severity in this cohort.
