Peripheral Nerves with Higher Long-Chain Omega-3s Better Protected from Injury

Peripheral nerves—those in the trunk and limbs—connect the brain and spinal cord to all other parts of the body. They allow us to sense temperature, pressure, touch and so on. If disease or injury damages the peripheral nerves, communication between the affected area and the brain is disrupted and sensory information may not be appropriately relayed. Such circumstances make an individual more susceptible to injury, burns and falls. Damage to the peripheral nerves is called peripheral neuropathy and can be sensed by tingling, numbness, pricking sensations or muscle weakness (Illustration)….

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…
