Brain Trauma might be more common than expected according to the Mayo Clinic. In a recent study published in the journal Epidemiology, researchers from the Mayo Clinic applied a new system for classifying injuries to the head and found that the incidence of traumatic brain injury is likely greater than has been estimated by the CDC.
What people often fail to remember and recognize is that even mild traumatic brain injuries can affect a person’s sensory motor functions, thinking, awareness and communication. A lot of people have gone undiagnosed.
Researchers came up with the Mayo Traumatic Brain Injury Classification System, a new brain injury method that classifies head injuries with new categories. The categories label patients with “definite,” “probable” and “possible” TBIs, providing a way to incorporate symptoms such as a brief period of unconsciousness or even an injured patient’s complaint of dizziness or nausea.
Researchers are finding a strong link between TBI and post traumatic stress disorder. Researchers found a causal link between mild traumatic brain injuries and PTSD. There is an increased susceptibility to developing PTSD. People who have sustained a mild TBI are also more likely to develop an anxiety disorder.
An experimental drug might limit stroke damage. There is currently only one effective treatment for stroke, which is a Tissue Plasminogen Activator TPA that can dissolve blood clots that cause a stroke. the catch is that is has to be given very soon after symptoms appear and doctors first have to make sure that the stroke itself was not caused by a ruptured blood vessel. If that was the case, TPA can make the situation a lot worse.
At the Toronto Western Hospital Research Institute in Canada, it was discovered that a drug known as a PSD-95 inhibitor could be used as a treatment for strokes. It works by blocking a key protein that leads to brain-cell death. The study has been published in the journal, Nature.
Daily doses of a drug, Amantadine, used to treat Parkinson’s disease may help treat brain injuries according to a new study. The drug was given to patients who had suffered severe brain injuries. The doctors found that the drug helped with recovery and noticed a difference between patients who were given the drug and patients who were part of the clinical study that did not receive the drug.
Amantadine was also used as a flu drug in the past. When given to patients with serious traumatic brain injuries, it was noted that far fewer patients who were given this drug remained in a vegetative state. Visible steps towards recovery was seen.
Another medication being tested as a treatment for brain injuries is Clazosentan. A TBI causes a decrease of blood flow to the cerebrum of the brain. There is a receptor in the brain called endothelin receptor A (ETrA) contributes to the restriction of blood flow as early as four hours after a brain injury. Clazosentan is thought to specifically block these receptors.
How can doctors truly diagnose a brain injury? ABC news posted an article about detecting unseen damage in the brain with traumatic brain injuries. Doctors often miss brain injury damage that doesn’t show up on scans. Scientists are in the process of testing a tool that lights up the damage caused to the brain’s wiring by blows to the heads. Scientists want to make these “invisible wounds” visible.
For doctors, if they can’t see or quantify the damage, it’s hard to treat it. Especially with more serious head injuries, standard scans, like CT scans cannot see beyond bleeding or swelling to tell if the brain’s connections are broken in a way it that it can’t repair on its own.
Scientists are looking into technology called fibre -tracking, referring to nerve fibre, which act like a telephone network. These fibres make up the white matter of the brain. The new proposed MRI scan examines these connections and detects if any connects have been broken.
