Traumatic Brain Injury (TBI) may affect a person’s cognitive abilities, including learning and thinking skills. TBI has devastating acute effects and in many cases seems to initiate long-term neurodegeneration and it is a complex and heterogeneous disorder, the type and extent of the acute pathology probably have an important role in determining the risk of developing Alzheimer’s disease. Falls are the most common cause of traumatic brain injuries, where older adults are more susceptible to falling, which places them at a higher risk for traumatic brain injuries. Suffering a moderate to severe TBI has been linked to a higher risk of developing Alzheimer’s disease after the original injury. Depending on the nature of the traumatic brain injury and the severity of symptoms, brain imaging with computed tomography (CT) may be needed to determine if there's bleeding or swelling in the brain.
