Title of this presentation: A Brain is a Terrible Thing to Damage
We will focus our presentation on: STROKE
This presentation has been brought to you by: Lauren Wade, John DeLorenzo, and Kunal Patel
What is Stroke?
- It is to the brain what heart attack is to the heart.
- It occurs when a blood flow to an area of the brain is interupted.
- This can happen if a blood clot blocks a blood vessel or artery in the brain.
- Or when a blood vessel in the brain breaks/leaks.
- This leads to the death of brain cells because they are not getting oxygen, water, and nutreints from the blood.
- When these brain cells die, they give off chemicals that damages neighboring brain cells and kills them as well.
- After few minutes without treatment, a chain reaction of brain cells killing other brain cells occur.
- As a result, a region of the brain dies.
- When a region of the brain dies, so does everything that part of the brain was responsible for doing as a living.
- Examples of something that a person can loose: the ability to speak, move, memorize, or even understand stuff.
Risk factors for stroke
hemianopia (hemianopsia)
- It is defined by blindness in one half of the visual field of one or both eye.
- This can happen from a variety of medical conditions. But, the most common cause is stroke.
- Just like stroke, this defect can occur on either right or left side, depending on which side stroke has occured.
- E.G., stroke patients with weakness on the right arm and leg has poor vision on their right eye.
- Brain damage to lead to hemianopia.
- There are multiple types of Hemianopsia:
- Absolute: the eye affected is completely blind to light, form, and shape.
- Relative: loss of form and color on the affected eye but not light.
- Congruous: both eyes with equal defects.
- Incongruous: both eyes defected differently in one or more ways.
- Homonymous: nasal half of one eye and temporal half of the other eye are defected.
- Bitemporal: both temporal halves of the temporal lobe are defected.
- There is no treatment for hemianopsia. But, the severity of it does decrease over time.
- Anyone diagnosed with this problem should not be allowed to drive.
