A blow to the head can change your life in an instant.
Traumatic brain injury (TBI), or head injury, is common, particularly in young adults and the elderly, but the causes differ. Young adults usually suffer a TBI from a road traffic accident or a fallfrom height, and it is one of the leading causes of death and disability in this group. However, in older people, falls are the top cause of head injuries.
Elderly patients often suffer from age-related diseases and take medications that can affect their vision, muscular strength, coordination, and thinking. This makes them prone to falls during normal daily activities, such as toileting, showering, or even when getting out of bed.
“But my grandmother seemed okay…”
A minor head injury can have serious consequences in the elderly because the brain shrinks as we age. This creates more space inside the skull for the brain to move when the head is hit. With more movement, there is an increased risk of damage to blood vessels, causing blood to gradually pool under the skull, a condition known as chronic subdural haematoma.
This ‘delayed’ bleeding from a mild TBI can occur weeks to months after the head injury and may require surgery. A head injury can happen at any time — know the signs of brain injury and when to seek medical help!
