After a Brain Injury, Mental Health Follow-Up Matters
A concussion or other traumatic brain injury (TBI) can change daily life in ways that are hard to see. Alongside physical symptoms, a person may face changes in mood, sleep, concentration, relationships, or independence. A 2018 Psychiatric News article highlighted research that gives health care teams another reason to make mental health a routine part of brain injury follow-up.
In the study published in JAMA, researchers examined health records for more than 7.4 million people in Denmark over 35 years. About 568,000 had received medical care for a TBI. The suicide rate among people with a recorded TBI was about 41 deaths per 100,000 person-years, compared with about 20 among people without a recorded TBI. After accounting for several other factors, the rate remained about 1.9 times as high in the TBI group.
The association was stronger after severe injuries and among people with multiple TBI-related medical contacts. It was highest in the first six months after the most recent medical contact for TBI, although elevated risk persisted years later. These figures describe patterns across a population; they cannot predict what will happen to any one person. As Psychiatric News notes, 0.62% of people with a recorded TBI in the study died by suicide. The great majority did not.
What the findings mean for care
The study did not establish that TBI itself caused the higher suicide rate, nor did it test which follow-up practices reduce risk. It counted injuries documented in medical records, so some injuries that never led to care were missed. The researchers also lacked details about treatment and the specific psychiatric conditions people experienced after injury. Still, its findings point to opportunities to make care more connected and responsive.
For a person recovering from a brain injury, a discharge plan should be the beginning of a conversation. At follow-up visits, clinicians can ask about mood, sleep, distress, and thoughts of suicide in a direct, compassionate way. They can also ask about earlier head injuries. Clinicians interviewed by Psychiatric News stressed the need to recognize and address the wider range of psychiatric symptoms that can follow TBI, rather than focusing on suicide risk alone.
When someone needs more support, the care team can work with that person to make a safety plan, connect them with appropriate treatment, and confirm that the next appointment actually happens. Support should remain available beyond the first few months.
Families and friends can help by noticing changes and making room for honest conversation. A person may need help arranging transportation, remembering appointments, or explaining symptoms to a clinician. Listening without judgment and helping them reach care can make it easier to speak up. A brain injury should never be treated as a label that defines someone or makes suicide inevitable.
The Zero Suicide connection
The Zero Suicide framework calls on health and behavioral health organizations to identify risk, engage people in collaborative care, treat suicidal thoughts and behaviors, and support safe transitions between providers. For people recovering from TBI, that means linking emergency care, rehabilitation, primary care, and behavioral health so that concerns are heard and referrals do not end with a phone number on a discharge sheet. This is a practical application of the framework, not a specific intervention tested by the Danish study.
The central lesson is one of attention and continuity: ask how the whole person is doing, make it safe to answer honestly, and stay connected through recovery.
