Wednesday, April 21, 2021 (HealthDay News)-People who have suffered trauma brain The risk of injury (TBI) is much higher Stroke British researchers said that for many years thereafter.

Previous studies have linked brain damage to the long-term risk of neurological diseases, including dementia, Parkinson’s disease and epilepsy, And some people think that this is also an independent risk factor for stroke.

A new review of 18 studies from four countries found that these patients had an 86% higher risk of stroke compared to people without TBI.

Although patients have the greatest increased risk in the first four months of illness Head injuryAccording to the authors of the new review, it remains significant for up to five years.

“Patients with TBI should be informed that they may increase their risk of stroke and that they are at the highest risk of stroke in the first four months after injury. This is a critical period for educating patients and their caregivers about the risk and symptoms of stroke. Turner (Grace Turner) said.

She and her colleagues found that regardless of the severity or type of injury, TBI is a risk factor for stroke.

They say this is important because 70% to 90% of these heads are mild. They added that the findings indicate that even with mild TBI and the patient is recovering well, TBI should be treated as a chronic disease.

Use certain Blood thinner, Such as Vitamin K Antagonists (VKA) and Statins, Can help reduce the risk of stroke in TBI patients, and certain types of Antidepressants Studies have found that these diseases are associated with an increased risk of stroke after injury.The research was recently published in International Stroke Journal.

Turner said: “Our review found some evidence that there is an association between the reduced risk of stroke after TBI and the stroke prevention drug VKA and statins. However, as previous studies have found, when individuals experience TBI, stroke prevention drugs are usually Will stop using it.” University press release.

More research is needed to evaluate the effectiveness of stroke prevention drugs after brain injury to help guide treatment.

Turner said that clinicians should take steps within the first four months after TBI to reduce the patient’s excessive risk of stroke.

According to the research team’s data, more than 60 million people worldwide suffer traumatic brain injury each year, and stroke is the second leading cause of death and the third leading cause of disability in the world.
