What is chronic traumatic encephalopathy or CTE?

Chronic traumatic encephalopathy (CTE) is the term used to describe brain degeneration likely caused by repeated head traumas. CTE is a diagnosis made only at autopsy by studying sections of the brain.

Is CTE and TBI the same?

Chronic Traumatic Encephalopathy, or CTE, is a progressive degenerative disease affecting people who have suffered repeated concussions and traumatic brain injuries, that may occur in some athletes and others who have been exposed to concussions and repetitive head impacts.

What are 3 symptoms of CTE?

The symptoms of CTE include memory loss, confusion, impaired judgment, impulse control problems, aggression, depression, anxiety, suicidality, parkinsonism, and, eventually, progressive dementia. These symptoms often begin years or even decades after the last brain trauma or end of active athletic involvement.

Does TBI lead to CTE?

Traumatic brain injuries, including concussions, and repeated hits to the head, called subconcussive head impacts, may lead to CTE.

What are the four stages of CTE?

Going through the Stages of CTE

• Stage I. This first stage is most commonly marked by headaches, and loss of attention and concentration.
• Stage II. Depression, moods swings, headache, and short-term memory loss top the list of most frequently experienced symptoms in Stage II.
• Stage III.
• Stage IV.

How long does CTE take to develop?

The symptoms of CTE vary between individuals, but tend to be similar to those of other types of degenerative brain conditions, particularly Alzheimer’s disease. CTE usually begins gradually several years after receiving repetitive blows to the head or repeated concussions.

What is the first stage of CTE?

Stage 1. Patient is clinically asymptomatic or may complain of mild short-term memory deficits, or depressive symptoms; mild aggressive symptoms have also been reported. Stage 2. Mood and behavioral symptoms are more severe and may include explosive behavioral outbursts and more severe depressive symptoms.

Does CTE cause anger?

Examples of the breadth of mental health problems attributed to CTE include depression and anxiety (12–14); substance abuse (1, 12, 13); personality changes, anger control problems, and violence (12–14); and suicidal thinking and death by suicide (13–19).

What is the average lifespan of someone with CTE?

Some researchers believe the severity of the disease might correlate with the length of time a person spend participating in the sport. Unfortunately, a 2009 analysis of 51 people who experience CTE found the average lifespan of those with the disease is just 51 years.

Who is most at risk for CTE?

Those at greatest risk for CTE are athletes who play contact sports (e.g., boxers, football players, etc.) and military veterans, likely due to their increased chances of enduring repeated blows to the head.

Can you live long with CTE?

Many symptoms of CTE are treatable, and resources are available to help you find support and live a full life. It is also important to know that people who appeared to have CTE while alive have been found not to have CTE upon post-mortem examination of their brain.

How is CTE diagnosed?

Diagnosis. Eventually, the hope is to use a range of neuropsychological tests, brain imaging and biomarkers to diagnose CTE. In particular, imaging of amyloid and tau proteins will aid in diagnosis.

Is there treatment for CTE?

When CTE is suspected, a thorough medical history, mental status testing, neurological exams, brain imaging and further diagnostic tests may be used to rule out other possible causes. Today, there is no treatment and no cure for CTE. The only known way to prevent it is to avoid repeated head injuries.

How does CTE affect the brain?

Postmortem analyses have indicated that the symptoms of CTE are associated with neuropathological changes in the brain that are specific to repeated head trauma. Such changes include the atrophy of certain brain structures, such as the cerebral cortex, diencephalon, and medial temporal lobe, as well as the degeneration of myelinated neurons.
