Factors Related to Depression Symptoms in Chronic Poststroke Aphasia

Area of Science:

• Neuroscience
• Clinical Psychology
• Rehabilitation Medicine

Background:

• Left-hemisphere stroke often leads to aphasia, impacting communication and cognitive functions.
• Depression is a common comorbidity following stroke, affecting recovery and quality of life.

Purpose of the Study:

• To investigate the association between depression symptoms and demographic factors in adults with chronic left-hemisphere stroke and aphasia.
• To identify specific stroke-related disabilities and impairments that correlate with depression in this population.

Main Methods:

• A cross-sectional study involving 92 chronic left-hemisphere stroke survivors with aphasia and 70 controls.
• Depression symptoms were measured using the Beck Depression Inventory-II (BDI-II).
• Stroke-related disability (cognitive, physical, social participation, self-perceived recovery) and impairments (language, motor) were assessed using validated scales.

Main Results:

• Stroke survivors scored an average of 3.4 points higher on the BDI-II compared to controls.
• Higher depression scores were significantly associated with lower cognitive function, reduced social participation, and poorer self-perceived recovery.
• Age was inversely related to depression symptom scores.

Conclusions:

• Cognitive and communication disabilities, social participation, and self-perceived recovery are primary correlates of depression in chronic left-hemisphere stroke with aphasia.
• These findings underscore the need for ongoing depression screening post-stroke.
• Identifying these correlates can inform targeted psychological interventions and rehabilitation strategies.
