Traumatic Brain Injury And Alzheimer’s Disease Have The Same Effect On Brain Cells

America is one of the largest countries with great health care facilities in the world. Even though they have good health care facilities, studies show that in 2020 over 5.8 million cases of Alzheimer’s disease were reported, and it is predicted that by the year 2060, the number of people with Alzheimer’s would be tripled to 14 million. 

Traumatic Brain Injury And Alzheimer’s Disease Have The Same Effect On Brain Cells

Alzheimer’s disease, also referred to as Alzheimer’s or Dementia which is a neurodegenerative disease that starts slow but worsens with time. Some of the common symptoms are difficulty in remembering recent events, the problem with language, disorientation, and many more, which gradually cause death. There are three stages of Alzheimer’s such as early, middle, and last stage. The cause for this disease is still poorly understood. 

Traumatic Brain Injury And Alzheimer's Disease Have The Same Effect On Brain Cells

Studies from the University of Southern California show that both Alzheimer’s and traumatic head injury affects the brain. A traumatic brain injury (TBI) includes a sudden injury to the brain when a bump, blow, jolt, or any other injury damages the brain. They can be moderate or severe, depending upon the type of injury or damages caused to the brain. Some of the common symptoms of TBI are Blurry vision, neck pain, ringing in the ears, nausea or vomiting, headache, seizures, slurred speech, trouble waking up, and many more.

Some traumatic brain injuries have long-lasting effects which may cause physical, behavioral, communicative, or mental injuries. These injuries can be treated by learning coping strategies and through emotional support. 

The assistant professor of gerontology, neuroscience, and biomedical engineering at the University of Sothern California has stated that the records show that the cognitive impairment following a traumatic brain injury helped predict that Alzheimer’s and traumatic brain injury does the same magnitude of damage to the brain. Reports show that more than 1.7 million Americans every year suffer from brain injury, which leads to changes in brain functions and structure leading to thinking and memory struggles. 

The study included 33 people who suffered Traumatic Brain Injury, 66 people who had Alzheimer’s, and a control group of 81helathy people without Alzheimer’s or Traumatic Brain Injury. The results show that the patients suffering from Traumatic Brain Injury and Alzheimer’s have cortical thinning. Cortical thinning is the loss of brain cells called neurons, which in turn disrupts attention and arousal processes along with visual memory for social stimuli. It also declines the ability to make decisions, absorb new information and adapt behavior to new situations. 

Researchers have also found significant similarities between Traumatic Brain Injury and Alzheimer’s on how the grey and white matter deteriorate. The grey matter is responsible for memory and decision-making. In contrast, the white matter is responsible for fornix (involved in memory), corpus callosum (which helps in information exchange between brain hemispheres), and corona radiate (helps in movement of limbs). 

According to the US National Library of Medicine and National Institute of Health, Epidemiologic studies indicate that Traumatic Brain Injury in early to midlife is associated with the high risk of dementia in the later years. The risk appears high in the case of multiple Traumatic Brain Injuries. It is also found out that Traumatic Brain Injury can lead to dementia / Alzheimer’s if it is not taken care of in the early stages. Still, it can also cause dementia if there are any other brain-related damages.

Thus these results show that people with Traumatic Brain Injury have a high risk of suffering from Alzheimer’s disease. As per the MRI reports, both Traumatic Brain Injury, Alzheimer’s disease have the same effect on the brain cells.
