Depression after stroke: an investigation through catamnesis

Area of Science:

• Neurology
• Psychiatry
• Rehabilitation Medicine

Background:

• Depression is a known complication following stroke.
• Early-stage stroke may involve specific brain areas linked to mood disorders.
• This study investigates depression in stroke survivors 3 years post-stroke, focusing on lesion laterality.

Purpose of the Study:

• To evaluate the prevalence of depressive disorders in stroke patients 3 years after their first stroke.
• To determine if the hemispheric location of the brain lesion influences the presence or severity of depression.
• To assess the relationship between depression, social activities, and caregiver stress.

Main Methods:

• 180 stroke patients were interviewed at home 3 years post-stroke.
• Data collected included demographics, socioeconomic status, disability, depression (Beck Depression Inventory - BDI), and caregiver stress.
• Diagnosis of depression was confirmed using ICD-10 criteria; patients with prior psychiatric issues or severe attention deficits were excluded.

Main Results:

• 34% of patients (62/180) met criteria for depressive disorders (BDI score ≥ 14).
• No significant association was found between depression and the side of the brain lesion (left vs. right hemisphere) or education level.
• Higher BDI scores correlated with reduced social activities, and caregiver stress was primarily linked to patient disability and social dysfunction, not depression.

Conclusions:

• Depressive disorders are prevalent in stroke survivors long-term (≥3 years), irrespective of lesion location.
• These mood disorders negatively affect patient social engagement and leisure activities.
• Patient disability and social dysfunction significantly contribute to caregiver stress, with depression playing a lesser role.
