Q

Clinically stroke can be classified to 2 different classes, what are they?

A

Focal- particular area of brain is affected (due to artery occlusion or small hemorrhage)
Diffuse- the whole brain or multiple regions of the brain are affected. (patient usually unconscious)

17
Q

True/False: Both ischemia and hemorrhage lead to virtually the same clinical presentation. The only difference is mechanism

A

True

18
Q

Vascular event with symptoms similar to stroke.

A

Transient ischemic attack

19
Q

What is the main difference between Transient ischemic attack and stroke?

A

TIA persist for only a few minutes to a few hours and pts usually fully recover.

20
Q

What are clinically important because they ten to precede a stroke?

A

Transient ischemic attack

21
Q

Ischemic infarction of the brain caused by a platelet thrombus that develops over a disrupted atherosclerotic plaque in a cerebral artery.

A

Thrombotic ischemic stroke

22
Q

Thrombus has formed elsewhere detaches, travels to distal location where it lodges and occludes a vessel.

A

Embolic ischemic stroke

23
Q

What are some sources of emboli?

A

LEft atrium

carotid arteries

24
Q

__________ embolus is a venous embolus that passes through a patient foramen ovale and lodges in a cerebral artery.

A

Paradoxycal

25
Q

Ischemic stroke findings, mechanisms of stroke?

A

swelling of brain (herniation)
Loss of demarcation between gray and white matter
Breakdown myelin
Glial cells react to the injury

26
Q

What kind of stroke involves, contralateral hemiparesis and sensory loss mostly in face and upper extremity? (important)

A

Stroke involving MCA.

27
Q

Wernicke’s aphasia is what?

A

due to MCA and is fluent, no sense

28
Q

Brocas aphasia is what?

A

due to MCA and is not fluent and makes sense

29
Q

If you have ISOLATED symptoms and pure motor and pure sensory, what type of stroke was it most likely?

A

Lacunar stroke

30
Q

If patient has contralateral hemiparesis and sensory loss is predominantly in the LOWER extremity, and URINARY incontinence?

A

Anterior cerebral artery

31
Q

If patient has vertigo and ataxia what is most likely the stroke?

A

Vertebral-basilar system

32
Q

The vertebral-basilar system supplies what? SO its occlusion causes what?

A

LATERAL MEDULLA

lateral medullary syndrome, (WALLENBERG syndrome)

33
Q

Strokes involving posterior cerebral artery has what main symptoms?

A

Visual field defects

“Eyes look towards the lesion”

34
Q

Rupture of meningeal artery

A

Epidural

35
Q

Rupture of a bridging vein

A

Subdural

36
Q

Most often aneurysm rupture

A

Subarachnoid

“worst headache in my life”

37
Q

Arterial bleed creates a blood filled space between bone and dura mater? Lens shaped.

A

Epidural hematoma

38
Q

Rupture of bridging (emissary) veins between dura and arachnoid mater. Often seen in SHAKING BABY SYNDROME, ALCOHOLICS, elderly.

A

Subdural hematoma

39
Q

Worst headache of my life and sudden onset.

A

Subarachnoid hemorrhage

40
Q

What is most likely to have caused subarachnoid aneurysm?

A

berry aneurysm or arterial aneurysm
