    Suicidal ideation is common after mild traumatic brain injury (mTBI). Factors like English as a second language and depression history are linked to this risk, necessitating early screening and monitoring.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Public Health

    Background:

    • Concussion and mild traumatic brain injury (mTBI) can lead to long-term psychological effects.
    • Suicidal ideation (SI) is a significant concern following brain injury, but contributing factors and temporal development are not fully understood.

    Purpose of the Study:

    • To identify psychosocial and injury-related factors associated with suicidal ideation (SI) after concussion or mild traumatic brain injury (mTBI).
    • To examine the time course of suicidal ideation development at 3 and 6 months post-injury.

    Main Methods:

    • Prospective cohort study of 871 patients with mTBI assessed at 3 and 6 months post-injury.
    • Psychiatric and social-demographic data collected via clinic assessments.
    • Statistical analyses included Chi-square, t-tests, and logistic regression to identify independent predictors of SI.

    Main Results:

    • Suicidal ideation (SI) was present in 6.3% at 3 months and 8.2% at 6 months post-mTBI.
    • Independent predictors of SI at both 3 and 6 months included speaking English as a second language (ESL) and being a motor vehicle collision (MVC) passenger.
    • History of depression and marital status were associated with SI at 3 months only.

    Conclusions:

    • Suicidal ideation (SI) is prevalent in the early months following mild traumatic brain injury (mTBI).
    • Specific demographic (ESL) and injury-related factors (MVC passenger) are consistently associated with SI.
    • Early screening for predisposing factors and vigilant monitoring for suicidality are crucial for patients recovering from mTBI.
