Rerouting

The brain’s ability to form new neural pathways by redirecting functions previously managed by damaged areas to undamaged regions.

Sprouting

Sprouting refers to the process of undamaged neurons growing new axons or dendrites to form new connections with other neurons.

Traumatic Brain Injury

An injury that occurs after external force to the head, interrupting brain activity.

Wernicke’s Aphasia

A language condition where a person has trouble understanding and often says words that don’t make sense, even though they can speak fluently.

Broca’s Aphasia

A language condition where a person has trouble speaking clearly and forming sentences, but they can usually understand what others say.

Concussion

A mild traumatic brain injury in which the brain bounces inside the skull due to external force.

Two biological effects of a tbi

Headaches and damaged brain cells

Two psychological effects of a tbi

Mood swings and paranoia

Two social effects of a tbi

Social isolation and difficulties with social skills.

neurological disorder

A condition impacting the nervous system, which includes the brain, spinal cord and nerves.

2 examples of neurological disorders

parkinsons disease and alzheimer’s

Chronic traumatic encephalopathy

A degenerative disease caused by repetitive trauma to the head.

Physiological basis of cte (what happens?)

Tau protein builds up in the neurons in the brain, disrupting important processes that keep cells alive and healthy.

Explain the impact of the physiological basis of cte on the diagnosis of other neurodegenerative diseases.

Because CTE and other brain diseases can have similar brain damage and symptoms, it can be difficult to diagnose a living person.

2 examples of causes of cte

Repeated concussions, and repeated trauma while still conscious.

4 examples of stage 1 cte symptoms

Headaches, poor concentration, mild-aggression and explosivity.

4 examples of stage 2 cte symptoms

Cognitive and memory dysfunction increases, behavioural changes, aggression increases, suicidality.

4 examples of stage 3 cte symptoms

Mild dementia, cognitive and memory dysfunction increases, aggression increases, explosivity increases.

4 examples of stage 4 cte symptoms

Severe dementia, paranoia, depression, suicidality.

3 ways to prevent cte

Reduced repeated head impacts, use of proper safety gear, and following concussion protocols.
