New Study Confirms Link Between Brain Injury and Dementia

Persons who have suffered a traumatic brain injury have a much higher risk of developing dementia down the road. A new study not only underscores this fact, but also determines that changes in vascular cells can affect the onset of dementia in persons who have suffered a brain injury. Traumatic brain injuries often occur in car accidents, truck accidents, motorcycle accidents, pedestrian accidents and slip and falls.

For decades now, scientists have been aware that suffering a brain injury significantly increases the risk that a person will develop dementia or Alzheimer’s disease down the road. However, recent studies have identified the exact molecular mechanism behind the personal injury that can bring about dementia earlier. In this new study, scientists discovered that alterations to the vascular smooth muscle cells lead to an increase in the build-up of proteins called amyloid beta, which are strongly linked to Alzheimer’s disease. What the scientists found even more surprising is that even younger persons who are typically not at risk of dementia suffered a similar increased risk, supported by the vascular muscle cell changes following the brain injury. The researchers concluded that understanding the changes to the vascular cells is crucial to understanding how trauma can impact dementia risks and circumventing or mitigating those risks all together.

Brain injuries can result in a significant number of changes in a person’s mental and physical health. Even a moderate brain injury can result in cognitive challenges, memory problems, difficulties in concentration and attention, impaired motor skills and a number of other challenges that make it difficult for the person to live a normal life. All of these difficulties make it hard for the person to be productive or earn a living. Working even a routine job can become challenging. For example, motor coordination problems can manifest in a large number of brain injury victims, and these can significantly impact the victim’s earning potential if he is working in a manual job, or one that requires dexterity.

Memory Problems After Brain Injury Linked to Processing Deficit

by Robert N. Katz, Esq.

Persons who have suffered a brain injury may find it difficult to recall memories or make new memories. This could possibly be a result of processing deficits as a result of a personal injury. Car accidents, slip and fall accidents and similar traumatic events may result in brain injuries which lead to a processing deficit.

A brain injury can result in a number of cognitive and intellectual impairments. The person may suffer from concentration problems, cognitive deficits and a lowered ability to understand and grasp basic concepts and ideas. One of the more troubling parts of life after a brain injury is limited memory function. The person may struggle to recall events, and even short term memory may be affected. According to new research, a brain injury can result in slowing down of processing times or a processing deficit which can, in turn, lead to memory dysfunction. The findings of the study are important when you consider the fact that as many as 50% of patients who have suffered a brain injury do suffer from some kind of memory dysfunction.

The researchers believe that rehabilitation after a brain injury can help with memory function to some extent. They believe that therapy, especially occupational therapy techniques used during rehabilitation must include techniques to speed up processing speed.

Brain Implant Helps Car Accident Victims Recover Cognitive Abilities

by Robert N. Katz, Esq.

One of the most devastating consequences of a brain injury after a car accident is the effect on a person’s cognitive abilities. A new study finds that a brain stimulator device can help a person recover these critical abilities after a personal injury.

The findings of the study were published in a recent issue of the Nature Medicine journal. The researchers implanted the stimulators in the brains of persons who had suffered brain injuries as a result of trauma. The implants were left on for about 12 hours a day and the participants spent 3 months with the implants.

The research by scientists at Stanford University found that the implantation of the deep brain stimulator helped trigger electric activity in brain neurons that had been left damaged after trauma. While the researchers were hoping for a 10% increase in mental processing as a result of the implantation of the device, they were surprised to find that the improvement was as high as 32% in the patients. What is even more promising is that the device can help with impairments that have occurred as a result of old brain injuries. According to the scientists, the device offers great hope to persons who have suffered injuries that have left them with memory loss and poor thinking skills.

Dementia Patients Okay to Drive Says Neurology Group

by Robert N. Katz, Esq.

Elderly motorists in Georgia have restrictions imposed on their driving abilities. These are in place to make sure that senior citizens can continue to drive safely in Georgia, without endangering their own safety, as well as the lives and safety of other drivers. Driving for elderly people is not just a convenient way of getting around, but also a major factor in their mental health. Studies have shown that elderly citizens, who have their car keys taken away from them, can fall into a depression. More senior motorists may soon be able to continue with their driving privileges.

The American Academy of Neurology this week said that it would be revising its guidelines allowing patients with mild dementia to continue driving. As of now, the group does not recommend driving privileges for patients diagnosed with even a mild degree of dementia. However under the new guidelines, patients with mild dementia who have a safe accident record and whose families believe they can drive safely, may be able to continue to do so.

According to the group, studies seem to indicate that most persons who suffer from mild dementia pass driving tests successfully. In fact, studies showed that 77 percent of these persons were able to pass these tests, confirming their driving abilities.
