A large number of the brain injuries that occur each year are sustained in falls at home, it is claimed.
Among older American adults, traumatic brain injury (TBI) causes almost half of fall-related fatalities, according to a report in Medical News Today.
In children aged four and younger, TBI is said to be the primary cause of fall-related death and severe injury.
"Many head injuries occur at one's residence - whether it is a home or a nursing facility - and involve falling and bumping one''s head, resulting in mild concussions to severe and even fatal TBIs," said Gail Rosseau, a Chicago neurosurgeon and a spokesperson for the American Association of Neurological Surgeons (AANS).
Babies or toddlers under the age of four and adults aged 65 or older are the most vulnerable, according to the AANS.
The news comes after a study published in the Canadian Medical Association Journal called for the use of computed tomography (CT) scans in children to be standardised.
Dr Osmond, of the paediatrics department at the Children's Hospital of Eastern Ontario, and coauthors said there is growing concern linking exposure to ionising radiation with a heightened cancer risk.
