Dr. Peter Marincovich Talks About Concussions in Response to Latest News on TBI and Hearing Loss
Knowing the Signs and Symptoms Linked to Traumatic Brain Injury (TBI) Can Save Lives By Dr. Peter Marincovich, Ph.D.
SANTA ROSA, CA (PRWEB) MARCH 30, 2016
The biographical sports film “Concussion” raised public awareness of Traumatic Brain Injury (TBI) by turning the media spotlight on brain damage suffered by Pittsburgh Steelers Center Mike Webster during his football career, a condition only discovered during an autopsy after he was found dead in his pickup truck.
Recently, the specter of TBI was raised again by soccer icon Brandi Chastain, who revealed that she suffered two concussions while playing in college. Realizing that more research is needed, Brandi Chastain, along with Olympic swimming standout Jenny Thompson and Cindy Parlow Cone — one of Chastain’s teammates on the Women’s U.S. National Soccer team — have all agreed to donate their brains for concussion research when they pass away.
TBI is a significant public health concern and a major cause of permanent disability. This condition can impact the physiology, cognition, hearing loss, emotional regulation and social interactions of an individual, with long-term outcomes ranging from complete recovery to disability and death, according to the National Institute of Neurological Disorders and Stroke (NINDS). *1, 2
This overview is offered as a guide to physicians, educators and other professionals when making recommendations to individuals with TBI and their caregivers. It briefly covers what is known about brain changes that occur in the wake of a TBI incident, and discusses recent advances in cognitive remediation strategies that can be applied in connection with one specific TBI outcome — hearing loss. *3
Traumatic brain injury (TBI) is caused by a blow or jolt to the head, or by a penetrating head injury that disrupts the normal function of the brain. Each year in the United States, at least 1.7 million TBIs occur either as an isolated injury or in combination with other injuries, based on Centers for Disease Control (CDC) reports.*4
It is believed that these reports are low, due to the fact that many “mild” TBI cases are treated outside of hospital rooms in doctor’s offices and military facilities. Other less severe cases of TBI may go completely unreported, especially if the injured person does not recognize and report symptoms. *5
According to the CDC, the leading causes of TBI are falls (35%), motor vehicle accidents (17.3%), when a person is struck by or against something (16.5%), and assaults (10%). Falls cause 50% of TBIs among children aged 0-14, and among adults aged 65 years and older.
While motor vehicle accidents are the second leading cause of TBI, they make up the largest percentage of TBI-related deaths (31.8%). The very young (four years and younger) and adults over 75 have the highest risk of TBI, with males diagnosed more frequently (59%) than females.
Military personnel returning from combat in Iraq and Afghanistan have been profoundly affected by TBI with an estimated one in five soldiers experiencing a head injury, including blast-related trauma.
According to data published by the DVBIC, The Defense and Veterans Brain and Injury Center, the total number of service members with TBI diagnoses has more than doubled in the past five years with the majority categorized in the mild and moderate categories. Consequently. *6,7,8
In the sports world, it is estimated that a pro football player will receive an estimated 900 to 1,500 head blows during a season, making football a sport with a 75% chance of concussion for men, while soccer is the most common sport with a 50% chance of concussion for women. The impact speed of a football player tackling a stationary opponent is 25 mph, while the impact of soccer ball being headed by a player is 70 mph. *8, 9,10
