Is CTE the same as Alzheimer's?

Alzheimer's disease (AD) and chronic traumatic encephalopathy (CTE) have long been recognized as sharing some similar neuropathological features, mainly the presence of neurofibrilary tangles and hyperphosphorylated tau, but have generally been described as distinct entities.

How is CTE distinguishable from Alzheimer's?

A brain with Alzheimer's and a brain with CTE both show similar shrinkage in the hippocampus and accumulation of the protein Tau resulting in memory difficulties as well as behavior and mood changes. When CTE is suspected, many of the same dementia caregiving and communication techniques tips apply.

Can you get dementia from CTE?

CTE usually begins gradually several years after receiving repetitive blows to the head or repeated concussions. The symptoms affect the functioning of the brain and eventually lead to dementia.

Does CTE always get worse?

Instead of a single injury, it's a degenerative neurological condition, meaning that it gets worse over time, Manning said. The only common threads in these cases are that they involve brain damage and are commonly seen in contact sports like boxing and U.S. football.

Does CTE show up on MRI?

How is CTE diagnosed? At this time CTE can only be diagnosed after death by postmortem neuropathological analysis. Right now there is no known way to use MRI, CT, or other brain imaging methods to diagnose CTE. The CTE Center is actively conducting research aimed at learning how to diagnose CTE during life.

Can CTE be cured?

Treatment. There is no cure or treatment for CTE, but certain medicines may be used to temporarily treat the cognitive (memory and thinking) and behavioral symptoms.

How is CTE different from other brain diseases?

  • Like Alzheimer’s, CTE involves tau, a protein in nerve cells that has been associated with dementia. However, researchers have found that CTE has a unique pattern of abnormal tau buildup in the tissues around the blood vessels that is different from other brain diseases involving tau — including Alzheimer’s.

Can a person with dementia be cured of CTE?

  • Like dementias including Alzheimer’s disease, CTE cannot be cured. Unlike Alzheimer’s, the cause of CTE is known: it has never been found in the brain of a person who did not have a history of head hits. CTE is a degenerative brain disease caused by clumps of a protein called tau.

Who is more at risk for Alzheimer's and CTE?

  • Studies have shown that professional football players are four times more likely to develop Alzheimer’s disease than the general population. Because the brains of National Football League players have been shown overwhelmingly to exhibit signs of CTE after death, this suggests that someone with CTE is at much higher risk.

What are symptoms of chronic traumatic encephalopathy ( CTE )?

  • CTE is a progressive and neurodegenerative disease, meaning symptoms worsen as it spreads across the brain. Aggression, moodiness, and a loss of motivation are symptoms commonly associated with CTE, and the disease can result in dementia. Like dementias including Alzheimer’s disease, CTE cannot be cured.
