Alzheimer’s
What kind of brain disease is Alzheimer's?
Degenerative
What is an epileptic seizure?
Abnormal electric discharge of neurons
The four types of brain injuries
1. Concussion
2. Contusion
3. Cerebral edema
4. Subdural hematoma
Define MS
MS (Multiple Sclerosis) is myelin sheath that is destroyed.
What the more commonly known name for CVA?
A stroke
What are (at least) three symptoms of Alzheimer's?
Memory loss, Irritability, Confusion, Hallucinations, Death
What are the symptoms of epilepsy?
Uncontrolled or excessive activity of some parts or all of the CNS
Which TBI has nervous tissue destruction?
Contusion
What are the symptoms of MS?
A tingling sensation and numbness
What are the symptoms of a stroke(CVA)?
Sudden weakness in the face, arms, or legs.
How does a person get Alzheimer's?
Genetic, lifestyle and environmental factors
How does an epileptic seizure happen?
When the basal level of excitability rises above a specific threshold
How does a contusion differ from a concussion?
Contusions are severe traumatic brain injuries, causing nervous tissue destruction that doesn't regenerate. In contrast, concussions are far milder injuries that cause bleeding and tearing of the nerve fibers at most. Recovery from contusions is unlikely, but for concussions with some memory loss, recovery is likely.
What is the cure for MS?
There is no exact cure, there are only treatments to manage it
If the right side of the brain is having stroke, which side of the body would face it’s impacts of paralyzation? Why?
The left side of the body, since each hemisphere of the brain controls muscles and glands on the opposite side of the body.
What structural changes occur during Alzheimer's?
1. Abnormal beta-amyloid protein deposits
2. Twisted TAU fibers in neurons
At what age does epilepsy occur?
It can affect all ages
What happens to the brain when a cerebral edema occurs?
Swelling from the inflammatory response
What is the age range for MS?
18-55
What are the two different types of Cerebrovascular accidents? What is the difference between the two?
Ischemic and hemorrhagic- ischemic cerebrovascular accidents is when there is a blockage of blood vessels that limit blood flow to affected area, while hemorrhagic cerebrovascular accidents are the rupture of blood vessels causing blood to leak out.
How is Alzhimers diagnosed?
It cannot be fully diagnosed until after death in an autopsy, where the Brain is examined for AD-related changes.
What are the four main types of epilepsy?
Focal, generalized, combination of focal and generalized and unknown
What part of the brain does blood collect during a subdural hematoma?
Below the dura
Is MS mostly common in males or females?
Females
What causes the brain to have a cerebrovascular accident?
When a blood vessel supplying brain region ruptures, oxygen cannot make its way to the tissue causing the brain tissue to lose functions or die in response to lack of oxygen.
