Is Suicide in US Military Personnel Related to Low DHA Status?

Suicide is a global problem, prevalent among adolescents, the elderly and active-duty military personnel. Among US active-duty military, suicide is the second leading cause of death, whereas in the general adult population, it ranks ninth. What attracted popular attention to this high occurrence was a news report that up until 2009, the number of suicides in the US military exceeded the number of combat deaths. This fact also drew the attention of researchers in the Uniformed Services University and the National Institutes of Health, Bethesda, USA. It is known that…

DHA has Positive Effects in Traumatic Brain Injury

Traumatic brain injury (Figure) results in about 53,000 deaths in the U.S. every year, with nearly twice that number suffering permanent disability, which sometimes includes diminished cognitive ability. Treatments with long-term benefits are few and of limited effectiveness. One potential treatment to watch for is progesterone, a female hormone that may have neurological benefits. Another potential treatment is DHA, a long-chain omega-3 fatty acid found mainly in fish and fish oil. There is a strong rationale to investigate the effects of DHA in brain and spinal cord injury. It is…

The latter are of particular concern regarding the Iraq and Afghanistan wars, among whom suicide is the second leading cause of death (13.1%) compared with the ninth rank for the general US adult population (1.8%). Up to 2009, the number of suicides exceeded the number of combat deaths in the US military. Although a past attempted suicide is a strong predictor of suicide, other conditions, such as mental disorders, including depressive…

Positive Effects of DHA in Experimental Traumatic Brain Injury

Traumatic brain injury results in 53,000 deaths in the U.S. every year (Figure), with nearly twice that number suffering permanent disability, including diminished cognitive ability. Treatments with long-term benefits are few and of limited effectiveness.  Progesterone may have neurological benefits and is in a Phase III clinical trial for patients with moderate-to-severe traumatic brain injury. Attention has also turned to the potential effects of DHA in preventing and ameliorating traumatic brain and spinal cord injury. DHA involvement in neuronal membrane structure and function, learning and memory, as well as neuroplasticity…
