Stroke risk higher after traumatic brain injury
PEOPLE who sustain a traumatic brain injury (TBI) are at a 10-fold increased risk of stroke within the first three months of their injury, a large study has shown.
While this risk decreases over time, the study of almost 93,000 people showed it was still significant one year after a TBI (more than fourfold) and five years after a TBI (more than twofold).
The risk of subarachnoid haemorrhage and intra-cerebral haemorrhage was also more noticeable among those with a TBI than those unaffected by a TBI.
The researchers, from Taiwan, said the results of this prospective population study – the first of its kind – had important clinical implications.
“More intensive medical monitoring, support and intervention are required following a TBI, especially during the first few months or years, as the risk of stroke decreases gradually after TBI,” they said.
“In an acute stroke situation, prompt recognition of
