We always knew that a hit on your head won’t make you smarter. Now researchers from the University of Amsterdam published a new study showing the real impact of Traumatic Brain Injury (TBI) on intelligence.
Traumatic Brain Injury (TBI)
Traumatic Brain Injury (TBI) is common. Worldwide, 50–60 million people suffer from traumatic brain injury (TBI) each year. TBI is the leading cause of death in North America for people below 45 years. The UAE has a comparably young population which makes Traumatic Brain Injury (TBI) a very common and serious disease. Most common cause of TBI in the UAE are road and traffic accidents.
The new study from the Netherlands is currently the most comprehensive study quantifying the impact of Traumatic Brain Injury (TBI) on intelligence. The researchers conducted a meta-analysis of 81 peer-reviewed articles including 3890 patients with TBI. The study was published in the European Journal of Neurology.
Both, moderate and severe Traumatic Brain Injury (TBI) cause persisting intelligence impairments in the subacute and chronic phase. Children seem to have better long-term outcome of mild TBI and poorer long-term outcome of severe TBI than adults. Patients with mild TBI showed no meaningful intelligence impairments in the subacute phase of recovery, but impairments in the chronic phase.
“In conclusion, TBI causes persisting intelligence impairments, where children may have better recovery from mild TBI and poorer recovery from severe TBI than adults.” researchers from the University of Amsterdam say.
