TBI and Alzheimer’s Disease

Brain Injuries Linked to Alzheimer’s
A recent brain injury study published in the Journal of Neuroscience delves deeper into the link that medical experts have identified between traumatic brain injury and Alzheimer’s. The authors cite considerable evidence that a single head trauma can trigger changes in brain chemistry associated with the development of dementia, memory loss, senility, and other symptoms indicative of Alzheimer’s disease. The neurologists involved in the study based their research on changes that occurred in the brains of mice within two days of a single TBI episode, as well as an analysis of brain tissue samples from autopsies of Alzheimer’s patients. The report found a reduction in the level of two intracellular brain proteins in the mice – the presence of which helps the brain maintain normal function – as well as an increase in a particular enzyme, two chemical components that are also present in Alzheimer’s patients.
Symptoms of Traumatic Brain Injury
A traumatic brain injury is characterized by a variety of symptoms, including amnesia, changes in mental status and unconsciousness. Although the term “traumatic” suggests a severe blow or penetrating head injury, TBIs can also be caused by minor jolts, blows or bumps. Furthermore, brain injury experts diagnose TBIs from mild to severe based on the extent of the symptoms, not on the violence of the injury. Concussions are the most common type of TBI, resulting from forces that make the head move rapidly without an actual blow to the skull. Common symptoms of concussion to watch out for include dizziness, headaches, balance problems, irritability, or lack of clear thinking after a car accident, sports injury or other trauma.
A Qualified Brain Injury Attorney Can Help
One problem associated with brain injuries involves victims settling a personal injury claim with an insurance company without fully understanding the extent of the injury. Car accident victims who believe they have only suffered minor injuries may find weeks or even months later that severe headaches, constant fatigue, or an inability to concentrate has decreased their quality of life and limited their ability to remain employed. Every kind of personal injury has the potential to cause long-term harm to the brain – not just car accidents, truck accidents and sports injuries – and research linking a single head trauma to the development of Alzheimer’s down the road is a very good reason for injury victims to ensure they receive a comprehensive medical diagnosis before settling their personal injury claim. An experienced brain injury lawyer in your area can help you explore your options for receiving proper medical care, and can help you seek fair and timely reimbursement for the full extent of your injuries.
