12. Traumatic Brain Injury – The Lingering Impact
Traumatic brain injury (TBI), caused by a blow to the head or a penetrating head injury, can have long-term consequences, including an increased risk of dementia. Both the severity and frequency of TBIs can contribute to this risk.
The damage from TBIs can lead to changes in brain structure and function, contributing to cognitive decline and dementia. It’s worth noting that even mild TBIs or concussions can increase dementia risk, particularly if they occur repeatedly, such as in sports-related injuries.
Preventing TBIs is an essential strategy for reducing dementia risk. This prevention can involve wearing seatbelts and helmets, fall-proofing homes, and using caution during physical activities.
As we continue to explore the risk factors for dementia, we realize the complexity of this condition. However, it’s crucial to remember that recognizing these risks can empower us to make lifestyle choices that enhance our cognitive health and reduce our dementia risk. (12)
