Personality changes and return to work after severe traumatic brain injury: a prospective study

Area of Science:

• Neuroscience
• Psychiatry
• Rehabilitation Medicine

Background:

• Severe traumatic brain injury (TBI) often leads to long-term disability, impacting patients' ability to return to work.
• Predicting non-return to work (nRTW) is crucial for effective rehabilitation planning and support.

Purpose of the Study:

• To identify predictors of nRTW in Brazilian patients following severe TBI.
• To examine the influence of social, demographic, clinical, and psychiatric factors on vocational outcomes.

Main Methods:

• A prospective study involving 43 community-dwelling individuals 18 months post-severe TBI.
• Assessment included DSM-IV-TR criteria for personality changes and SCID-I for psychiatric diagnoses.
• Clinical data comprised Glasgow Coma Scale, pupil findings, limb trauma, CT classification, and glucose levels.

Main Results:

• Personality changes emerged as the sole independent predictor of nRTW.
• The adjusted odds ratio for nRTW associated with personality changes was 10.92 (p=0.02).

Conclusions:

• Personality changes are a significant independent predictor of nRTW after severe TBI.
• Identifying risk factors for personality changes post-TBI is essential for early intervention.
• Effective interventions can mitigate the burden of TBI-related personality changes on vocational outcomes.
