Mild Head Injury Increases Risk of Parkinson's Disease
- May 02, 2018 -

A new large-scale study conducted on the veterans’ group showed that even a slight head injury can significantly increase the risk of individuals suffering from Parkinson's disease, according to the report of the United States' Palm Beach Post on April 25.

The new study published in the academic journal Neurology, published in April, focused on approximately 326,000 U.S. veterans between the ages of 31 and 65. During the course of the study, the researchers found that people who had had a concussion had a higher risk of Parkinson's disease than those who had had a concussion, had never experienced a change in consciousness, or had not experienced an amnesia within 24 hours. 56%. The soldiers who have suffered more severe brain trauma will have a greater risk of Parkinson's disease in the future. Veterans who have had moderate to severe traumatic brain injury are 83% more likely to have Parkinson's disease than soldiers who have not suffered brain damage.

Dr. Raquel Gardner, the principal investigator of the study, who works at the San Francisco Veterans Affairs Medical Center, said, "Although this is not the first indication that minor traumatic brain injury will also increase the risk of illness. Studies of the risk of the disease, but we were able to study every American veteran diagnosed by the Veterans Affairs Medical Center. Therefore, these research results are by far the most convincing data we have. These data show that brain damage There is indeed a certain link between the degree of and the probability of suffering from Parkinson's disease."

Another researcher at the University of California San Francisco (UCSF) and the San Francisco Veterans Affairs Medical Center, Kristine Yaffe, said that in fact, most of the people who have been diagnosed with The soldiers of Parkinson's disease have suffered varying degrees of injury on their heads. She explained that "because the research subjects in this study were once active military personnel, most of them suffered from traumatic brain injury in their lives after retirement."

But overall, the number of veterans diagnosed with Parkinson's disease is quite small. Of the 212 veterans who experienced concussion, only one soldier suffered from the disease. However, this rate was slightly higher among military personnel who experienced more severe moderate-to-severe brain injury. One out of 134 such ex-servicemen is suffering from Parkinson's disease. Dr. Michael Silver, an assistant professor at the Department of Neurology at Emory University, although not involved in the study, said that the data was "very compelling."

Dr. Seafer said, "This has always been a controversial issue, but most studies have found a correlation between traumatic brain injury (TBI) and Parkinson's disease. This is indeed a difficult question to study. Because if you want to study the probability of a group of patients with traumatic brain injury suffering from Parkinson's disease, you must be patient and keep track of and pay attention to their physical condition."

He said, "With the convincing data from the San Francisco Veterans Affairs Medical Center, especially the fact that traumatic brain injury is related to Parkinson's disease, we can integrate these data in a few years. ”

Although Dr. Seafer thinks this study is doing well, many factors are controllable. However, he suggested that a longer follow-up visit to the study would be more helpful for the study. “Because the average age of the study subjects is only 48 years old, I hope to follow them up longer, because the average age of Parkinson's disease is about 60 years old.” He said, “This is an interesting study. As we gather more data, the link between traumatic brain injury and Parkinson's disease will also become clearer."

Parkinson's disease is the most common neurodegenerative disease after Alzheimer's disease. With age, the risk of illness will gradually increase. At age 60, the risk of illness will be about 1%. By age 80, it will increase to about 4%. Dr. Siever said that so far, doctors have no way to interfere with Parkinson's disease. He suggested that people with head injuries must have a healthy diet and exercise. Because previous studies have shown that this can reduce the risk of Alzheimer's disease (a condition that Parkinson's disease may cause).

The researchers in this study also made similar suggestions for people concerned about the late development of Parkinson's disease. Gardner said that a healthy diet, regular exercise and medical control through medical means are the best ways to avoid any neurodegenerative diseases.
