Should the government do more to support veterans' mental health?

Veterans with mild traumatic brain injury from childhood showed more symptoms of PTSD, depression, anger, anxiety and emotional-behavioral dyscontrol, according to a study published Oct. 21 in the PLOS Mental Health Journal. Veterans with a childhood concussion who later earned a college degree or met federal physical activity guidelines showed significantly better mental health outcomes.

Why it matters

The findings suggest that an early head injury may have lasting effects on mental health well into adulthood, which could matter for how veterans are screened and supported. The study also points to education and physical activity as factors associated with better outcomes for this group.

The LIMBIC-CENC prospective longitudinal study of 1,286 veterans found that 61.3% had mild childhood TBI, with PTSD symptoms 36% higher than average and depression scores 31% higher. The study does not establish whether the link is causal, and the mechanisms behind the association remain unexplained.

The players

PLOS Mental Health Journal

A peer-reviewed journal that published the study on childhood brain injury and veteran mental health outcomes.

The details

Veterans with mild traumatic brain injury from childhood reported lower satisfaction with life and lower resilience than peers without it. Those who had a childhood concussion but later earned a college degree or met federal physical activity guidelines showed significantly better mental health outcomes.

Health Landscape

The findings extend the LIMBIC-CENC prospective study's record of how traumatic brain injury relates to later psychiatric symptoms in veterans. They add to a growing body of research connecting early head injury to adult mental health, though the study does not establish causation.

Veterans who experienced a concussion in childhood may benefit from mental health screening that accounts for early brain injury history. The study also suggests that completing a college degree or maintaining regular physical activity is associated with better mental health outcomes for this group.

The takeaway

Veterans with a history of childhood concussion may benefit from attention to mental health, and education and regular physical activity are linked to better outcomes in this group. Readers seeking support can discuss brain injury history with a clinician.
