A simple fall could have lasting effects on brain health. A new study of more than 260,000 older adults found that those who experienced a traumatic brain injury, often caused by hitting their head during a fall, had a 69% higher risk of developing dementia within five years compared with those who didn’t suffer head trauma.
The risk was highest among women over 75, adults over 85, and those living in small or low-income communities. Researchers believe head injuries can accelerate brain cell damage and trigger the buildup of proteins linked to Alzheimer’s and related disorders. In some cases, early cognitive decline may make falls more likely, creating a dangerous cycle of injury and worsening brain function.
Experts say prevention is key. Simple steps like strength and balance training, removing tripping hazards, and using proper footwear can dramatically cut fall risk. Protecting against head injuries, they say, isn’t just about avoiding immediate harm — it could also help prevent dementia later in life.
