Q

What is a stroke

A
  • Damage to the brain from interruption of its blood supply
  • Occurs when an artery supplying brain tissue is altered
  • Lack of blood supply = neuron death.

Types of stroke

A

Ischemic (due to occlusion)

Q

Medication for transient ischemic attack and examples

A

o Thrombolytic therapy:
rtPA turns plasminogen into plasmin (molecule that breaks up blood clots. Given within 6 hours.
o Anticoagulation:
Prevent clot formation by inhibiting platelet aggregation or interrupting clotting cascade (Aspirin).
o Beta blockers.

Q

Types of seizures with description

A

Tonic seizure = increase muscle tone/stiffness
Atonic seizure = complete muscle relaxation
clonic seizure = muscle convulsion
Myoclonic = muscle spasm in localised area
Absence = staring appearance with no movement
Tonic-clonic = stops moving and then started convulsion + loss of consciousness
Generalizes seizure = includes most all of brain

24
Q

How to diagnose meningitis

A

o history/symptoms
o clinical exam
o bloods
o lumbar puncture.

25

26
Q

What is Intracranial Pressure:

A

increase in volume of any of intracranial contents (brain tissue, blood, cerebrospinal fluid

27
Q

Risks that can cause intracranial pressure

A

o brain tumor
- head injury
o heart failure
o infections
o seizures

28
Q

Symptoms of intracranial pressure

A

31
Q

What is parkinson’s

A

brain conditions that cause slowed movements, rigidity (stiffness) and tremors

32
Q

Symptoms of parkinson’s

A

o tremor
o rigidity
o excess sweating
o constipation
o urinary retention.

33
Q

Parkinsons treatment

A

o management of symptoms.

34
Q

What is Neurogenic Shock:

A

due to nerve damage causing hypoperfusion

35
Q

What is distributive shock

A

vessels that deliver blood flow to the cells have an issue with distributing that flow.

36
Q

Risks that can cause distributive shock

A

o spinal cord trauma
o medications that affect the autonomic nervous system
o improper administration of spinal anesthesia.

37
Q

Symptoms of distributive shock

A

o hypotension
o bradycardia
o hypothermia
o warm/dry extremities but cold body.

38
Q

Diagnosis of distributive shock

A

o Physical
o CT
o MRI.

39
Q

Treatment for distrubitve shock

A

o Manage ABCs
o protect/immobilize spine
o intubation
o Vasopressors (causing vasoconstriction – increase BP), Nervous system: controls function we cannot consciously control – HR, digestion, breathing, pupil response.

40
Q

What is Sympathetic Nervous System:

A

o fight or flight.
o Increases HR, BP, dilates pupils for better vision.
o Controls vasomotor tone (regulates diameter of vessels – constriction or dilation)

41
Q

What is Guillain-Barre Syndrome

A
  • autoimmune neuro condition where the immune system attacks the nerves in the peripheral nervous system.
42

  • tingling sensation
43
Q

What is Multiple Sclerosis (MS)

A
  • an autoimmune disease in which the body attacks itself without any known cause or reason.
    -Affects the nerves of the brain and spinal cord.
44
Q

S+S multiple sclerosis (MS)

A
  • vision problems
  • muscle spasms
  • weakness or lack of co-ordination of the limbs
  • extreme tiredness
45
Q

Neurogenic shock S+S

A
  • hypotension
