Traumatic Brain Injury Linked To Long-term Work Disability

Having a traumatic encephalon injury, nary matter really serious, is associated pinch a greater likelihood of qualifying for activity disablement up to 5 years later, according to a study published February 11, 2026, in Neurology®, nan aesculapian diary of the American Academy of Neurology. The study does not beryllium origin and effect, it only shows an association.

"Traumatic encephalon wounded tin consequence successful disablement that whitethorn make it difficult to return to work, yet being employed is basal for maintaining value of life and financial stability," said study writer Andrea Klang, MD, of Uppsala University successful Sweden. "While astir traumatic encephalon injuries are mild, betterment tin still beryllium incomplete. For terrible encephalon injuries, location tin beryllium lasting symptoms. Our study recovered nary matter nan severity, traumatic encephalon wounded was associated pinch a higher likelihood of a personification qualifying for activity disability."

For nan study, researchers utilized Swedish nationalist registries to place astir 100,000 group pinch traumatic encephalon wounded who were treated successful a infirmary aliases successful a specialized outpatient attraction sojourn and astir 1 cardinal group without encephalon injury. Participants had an mean property of 39.

Researchers divided those pinch traumatic encephalon wounded into 3 groups. People successful nan highest group, 1% of participants, had nan astir terrible encephalon injuries, requiring surgery. Those successful nan mediate group, 6% of participants, had been hospitalized 3 aliases much days but pinch nary surgery. Those successful nan lowest group, 93%, were hospitalized nary much than 2 days aliases not astatine all.

Participants were followed for 5 years. Researchers wished which participants had medically certified activity disability, verified by a expert arsenic a simplification successful activity capacity owed to unwellness aliases injury. They measured nan likelihood of group moving to and from activity disability, which was defined arsenic having a sick time off longer than 14 days aliases receiving disablement benefits.

Compared to those without encephalon injuries, each 3 groups of group pinch traumatic encephalon injuries had a higher likelihood of having activity disablement during nan 5 years of follow-up, pinch an mean long of 1,201 days connected disablement for group successful nan highest group and 526 days for group successful nan lowest group.

Over 5 years, 72% of nan group successful nan highest wounded group, 67% of those successful nan mediate group and 45% of those successful nan lowest group had astatine slightest 1 play of activity disablement compared to 26% successful nan non-injury group.

After adjusting for factors conscionable arsenic age, acquisition and occupation, researchers recovered that 1 period aft wounded group successful nan highest wounded group had a 43% chance of activity disability, group successful nan mediate group had a 29% chance and those successful nan lowest group had a 6% chance, compared to a 0.5% chance for group without encephalon injuries.

After akin adjustments, researchers recovered that 5 years aft wounded group successful nan highest group had a 13% chance of activity disability, nan mediate group had an 11% chance and nan lowest group a 7% chance, compared to a 4% chance for group without encephalon injuries.

Researchers besides recovered that for each groups, older property was associated pinch a higher likelihood of activity disability. In nan mediate and lowest groups, female activity arsenic good arsenic psychiatric and constituent usage disorders were besides associated pinch a higher risk.

"Our findings stress a request to connection long-term, individualized rehabilitation to each group pinch traumatic encephalon injuries to reside immoderate impairment," said Klang.

A limitation of nan study was that it looked only astatine group successful Sweden and results whitethorn not beryllium nan aforesaid for group successful different countries.

The study was supported by nan Swedish authorities nether nan Agreement connected Physician Education and Research, a nationalist business betwixt nan authorities and regions supporting objective investigation and aesculapian education.
