"Influence of modifiable and non-modifiable variables on functioning in bipolar disorder: a path analytical study"

Area of Science:

• Neuroscience
• Psychiatry
• Psychology

Background:

• Bipolar disorder (BD) significantly impacts an individual's functioning.
• Understanding the factors influencing functioning in BD is crucial for effective treatment.
• Both modifiable and non-modifiable factors play a role in functional outcomes.

Purpose of the Study:

• To investigate the influence of modifiable factors (mood, cognitive reserve, cognitive performance) and non-modifiable factors (diagnosis, suicide attempts, substance use, age) on self-reported functioning in individuals with BD.
• To elucidate the interplay between these factors in predicting functional impairment.

Main Methods:

• A study involving 103 adults without mood disorders and 95 individuals with BD.
• Participants completed the WHODAS 2.0, a neuropsychological battery, and diagnostic assessments.
• Path analysis was employed to examine the relationships between predictors and functioning.

Main Results:

• Cognitive performance mediated the influence of cognitive reserve and age on functioning.
• Depressive symptoms and diagnosis had both direct and cognition-mediated effects on functioning.
• Psychiatric comorbidities, in addition to BD, significantly impacted individual functioning.

Conclusions:

• Cognitive performance, cognitive reserve, age, diagnosis, and depressive symptoms are key influences on functioning in BD.
• Executive functioning mediates the impact of age and cognitive reserve.
• Interventions focusing on depressive symptoms and cognitive stimulation may enhance functional recovery in BD patients.
