Individuals who’ve had a serious traumatic mind harm (TBI) could also be at elevated threat for dementia, in accordance with a brand new examine.
“Roughly 1 in 10 individuals in our examine who had main TBI did develop dementia,” mentioned examine co-author Dr. Rahul Raj, of the College of Helsinki in Finland.
A significant TBI was outlined as bleeding within the mind and a hospital keep of three or extra days.
The researchers analyzed 20 years of knowledge collected from almost 32,000 individuals in Finland who accomplished well being surveys each 5 years, and in contrast it with nationwide well being registries.
Amongst these within the examine, 288 had been hospitalized with a serious TBI and 406 had been hospitalized with a minor TBI (concussion with a hospital keep of not more than at some point) and didn’t have dementia inside a 12 months of their mind harm.
Over a mean 16 years of follow-up, 976 of the individuals within the examine developed dementia. They included 9% of these with main TBI, 2% of these with minor TBI, and three% of these with no historical past of TBI.
After adjusting for age and intercourse, individuals with main TBI had been 1.5 occasions extra prone to develop dementia than these with no TBI, the researchers concluded. There was no elevated threat for these with a minor mind harm.
However after additional adjustment for identified dementia threat elements equivalent to decrease ranges of schooling, smoking, consuming, inactivity and hypertension, the affiliation between main TBI and dementia weakened.
Ingesting and inactivity appeared to have the most important impact on weakening the affiliation, in accordance with the examine authors.
“Contemplating that there is no such thing as a remedy for dementia or TBI, the outcomes of our examine recommend that prevention of different dementia threat elements equivalent to extra alcohol consumption and bodily inactivity may probably scale back the danger of dementia in individuals with main TBI,” Raj added.
The outcomes seem within the May 11 on-line problem of the journal Neurology.
“Traumatic mind harm has been recognized as a doable threat issue for dementia, and as a result of growing numbers of individuals residing with dementia, it’s crucial to establish threat elements that could be modifiable to lower the quantity of people that develop dementia sooner or later,” Raj mentioned in a journal information launch.
Additionally, “extra analysis is required in bigger teams of individuals,” he added.
