Wellness/Prevention: Brain Injuries Are Becoming More Common in Older Adults.
Traumatic brain injury (TBI) occurs when a blow or impact to the head disrupts brain function, leading to headaches, dizziness, confusion, and problems with memory or concentration in the short term, and over the longer term elevating the risk of cognitive decline and neurological disorders. Using data from the Global Burden of Disease Study, researchers found an increasing upward trend in TBI incidence among adults beginning in their early 50s. The authors suggest this increase may be largely driven by falls, highlighting the importance of fall-prevention programs, home-safety modifications, and management of osteoporosis and frailty as part of an overall strategy to reduce the burden of TBI.
