Aphasia Exam 1 Aphasia overview

Question 1

Ischemic stroke (most common stroke)

Answer 1

blood vessel in the brain gets partially blocked, reducing blood supply to that area.

Question 2

Types of Ischemic stroke

Answer 2

Thrombus, Embolism, Transient ischemic attack (TIA)

Question 3

Thrombus

Answer 3

arteries become hard and narrow, making it hard for blood to flow. Can be caused by genes, smoking, high cholesterol, or not being active.

Question 4

Transient Ischemic Attack

Answer 4

Mini-stroke with temporary stroke-like symptoms that disappear within 24 hours. A warning sign of a future stroke.

Question 4

Embolism

Answer 4

blood clot or debris breaks off, travels through the bloodstream, blocks a smaller vessel, stopping blood flow

Question 5

Hemorrhagic Stroke

Answer 5

Bleeding in the brain

Question 6

Two types of Hemorrhagic Stroke

Answer 6

Subarachnoid & intracerebral

Question 7

Subarachnoid Hemorrhagic stroke

Answer 7

a bleed between the surface of the cerebrum and the skull (meninges)

Question 8

Intracerebral Hemorrhagic stroke

Answer 8

blood vessel in brain ruptures
2 types: Cerebral aneurysm, Arteriovenous malformation (AVM)

Question 9

Cerebral aneurysm

Answer 9

Weak blood vessel balloons out. Can burst.

Question 10

Arteriovenous malformation (AVM)

Answer 10

Twisted, tangled blood vessels.

Question 11

Atherosclerosis

Answer 11

chronic disease that affects the arteries, causing them to become narrowed and hardened (thrombus stroke)

Question 12

Infarction

Answer 12

blood flow to the heart muscle is completely blocked for an extended period.

Question 13

What two main arteries supply blood to the brain

Answer 13

carotid and vertebral arteries

Question 14

Carotid Arteries (arteries)

Answer 14

carry blood to the brain

Question 15

Vertebral Arteries (veins)

Answer 15

carry blood away from the brain

Question 16

Anterior Cerebral Artery (ACA)

Answer 16

supplies the medial (inner) surface of frontal and parietal lobes.

Question 17

Middle Cerebral Artery (MCA)

Answer 17

supplies the entire lateral (outer) surface of the brain. Largest branch of internal carotid artery

Question 18

Circle of Willis

Answer 18

Connects the ACA, MCA, and PCA arteries, allowing blood to flow from the opposite side if one side gets blocked

Question 19

Neoplasm

Answer 19

Brain tumors are abnormal growths in the brain that can be benign (non-cancerous) or malignant (cancerous).

Question 20

Brain tumor (Primary tumors)

Answer 20

abnormal growth of brain tissue and meninges; can result from trauma or injury

Question 21

Glioma

Answer 21

tumor composed of the glial tissue

Question 22

Astrocytoma

Answer 22

slow-growing, non-cancerous (benign) tumor in the brain or spinal cord made of a type of brain cell called astrocytes.

Question 23

Glioblastoma

Answer 23

fast-growing, cancerous (malignant) brain tumor that comes from glioblast cells.

Question 24

Meningiomas

Answer 24

tumors that grow between the meninges

Question 25

Aphasia

Answer 25

complex language impairment with patterns of relative strengths and weaknesses in language function

Question 25

Metastatic tumors (secondary tumors)

Answer 25

cancer cells break off from their original spot and spread to other parts of the body, it's called metastasis.
