Iron Accumulates in the Brain After Concussions, According to New Study

A study reveals a link between post-concussion headaches and increased brain iron levels, suggesting potential as a biomarker for understanding these conditions. Analyzing individuals with mild traumatic brain injuries against a control group, the research found significant differences in iron accumulation in specific brain regions, with the degree of accumulation correlating with the number of concussions and headache frequency.

The study involved 60 people who had post-traumatic headache due to mild traumatic brain injury, or concussion. The injuries were due to a fall in 45% of the people, 30% were due to a motor vehicle accident and 12% were due to a fight. Other causes were the head hitting against or by an object and sports injuries. A total of 46% of the people had one mild traumatic brain injury in their lifetime, 17% had two, 16% had three, 5% had four, and 16% had five or more mild traumatic brain injuries.

The study found that compared to the people without concussion, those with a history of concussion and headaches had higher levels of iron accumulation in several areas of the brain, including the left occipital area, right cerebellum, and right temporal lobe. For example, in the left occipital area, those with concussion and headaches had more iron accumulation than those with no concussion or headaches.
