What is the name of the rare condition linked to repetitive brain trauma that causes Tau protein infiltration?

1. Chronic Inflammatory Demyelinating Polyneuropathy

2. Chronic Traumatic Encephalopathy

3. Neurodegenerative Disorder

4. Multiple Sclerosis

The correct answer is: Chronic Traumatic Encephalopathy

The condition associated with repetitive brain trauma that leads to Tau protein infiltration is known as Chronic Traumatic Encephalopathy (CTE). CTE is a progressive degenerative disease of the brain that has been found in individuals with a history of repetitive brain injuries, particularly athletes involved in contact sports, as well as military veterans. This condition is characterized by the accumulation of Tau protein, which forms tangles in the brain and is associated with various cognitive, mood, and behavioral symptoms such as memory loss, confusion, aggression, depression, and progressive dementia. The presence of Tau pathology is a hallmark feature that differentiates CTE from other neurodegenerative disorders. This makes CTE a unique and critical area of study in understanding the long-term effects of brain injuries.
