Mild Brain Injury Leads To Early Cognitive Decline, Study In…




Mild traumatic brain injury causes early cognitive deterioration, according to a study of veterans.

A study published Wednesday in PLOS One found that military veterans who suffer a minor traumatic brain injury during war experience early cognitive decline within seven years after the incident.

According to the researchers, the consequences of the injury on cognitive function are comparable to those seen by those with early-stage Parkinson’s disease and much worse than those experienced by healthy non-veterans.

According to the National Institute on Aging, Parkinson’s disease is a brain ailment that causes tremors, stiffness, and problems walking, balance, and coordination.

The symptoms of dementia, such as memory loss and reductions in brain function, may develop, according to the institute.

According to the researchers, while the study focused on the hazards associated with a battle among veterans, the findings could have implications for individuals with a history of mild traumatic brain injury.

Researchers from the University of North Texas Health Science Center and Texas Christian University noted, “We found that young veterans with moderate traumatic brain injury are demonstrating certain particular premature cognitive aging effects.”

“[This] could be regarded a plausible trait linking remote mild traumatic brain injury to Parkinson’s disease later in life,” they said.

According to the National Institute of Neurological Disorders and Stroke, traumatic brain injury, or TBI, is an injury to the brain produced by an external force that happens when a sudden trauma results in brain damage.

It can happen when the head collides with something quickly and violently, or when an item pierces the skull and enters brain tissue. TBI is widespread among athletes and active-duty military personnel who are in conflict.

Between 2000 and 2018, active-duty servicemen and women experienced over 430,000 head injuries, with 82 percent of them being categorized as mild, according to the Department of Defense.

According to previous studies, veterans with a history of moderate TBI have a 56 percent increased risk of acquiring Parkinson’s disease within 12 years after their injury.

TBI has also been related to an increased incidence of ADHD in children and dementia in older persons, according to research.

The researchers looked at 27 veterans between the ages of 25 and 45 who had had a non-penetrating mild TBI (one that did not involve breaking through the skull) during the war in the previous seven years.

The researchers compared their performance on many measures of cognitive function to that of 30 healthy veterans and 30 healthy non-veterans who were all matched based on age and intelligence, as well as 27 people with Parkinson’s disease aged 60 to 90 at the start of the study.

The data showed that veterans with mild TBI and Parkinson’s took roughly 33% longer to complete tasks and fared worse than healthy veterans and non-veterans in all cognitive function assessments.

“In certain cognitive domains, we were able to find coincidental similarities between veterans with moderate TBI and Parkinson’s disease. We also discovered that veterans with mild TBI lag behind their age- and IQ-matched controls “The study’s authors noted.

On tests of cognitive flexibility, attention, processing speed, and inhibitory control, they “performed more like older, early-stage Parkinson’s disease participants and appeared cognitively as if they were at least three decades older,” they claimed.
