Q

What are strokes

1)Pathophysiology (what are 3 main types)
2)Common symptoms
3) treatment

A

Two main types of strokes with an additional
Cerebral vascular accident
Transit steam attack
Brain bleed-subarachnoid hemorrhage
Embolonic, athletic sclerosis, brain bleed- all results in disruption of blood flow to the brain-. Causing ischemia
2) fast aVVV
3) FIVER WINDOW STROKE CENTRE
Call stroke nurse if fast positive + convoy either stroke centre or local dependant on conversation

What is PNES (pyogenic non epileptic seizures)
1)Pathophysiology
2)Common symptoms
3) treatment

A

Lack of electricaln abnormalities rather a reaction to physiological of phycological stresses

Micceglss
Mouth closed - lack of tongue biting
Intense - fluctuating
Curveture - neck and spine
Cyanosis - lack of
Eyes - closed+ pupils pearl

Q

Obstructive Stroke (CVA) have two different causes

Q

What is are the main 2 risk factor for CVA & why

A

Atrial fibrillation - as it caused a circulation ot blood pool in the atrium causing clots that can move
- hypertension as it causes excess pressure on vessel - only so much till it explodes

Anticoagulant + head injury = clot or excess bleeding

Q

What is a focal seizure
2) what’s the difference between complex and partial seizures
3)bonus points what may focal seizures become ….

A

A seizure tha affect one hemisphere of the brain

2) complex = reduced awareness, simple = awareness commonly as a aura

3) focal seizures may intricate to generalised seizures

1) pathophysiology
2) sign and symptoms

23
Q

What is cerebral palsy

24
Q

What is a syncope
What are the characteristics associated with Syncopy ( general )

A

Syncope is when there is a temporary lack of blood supply to the brain resulting in a LOC ( loss of consciousness)

2) fast onset
Spontaneous recovery
Short duration

25
What are the three main overarching types of Syncopy
Reflex/ neural mediator syncope Orthostatic hypotension syncope Cardiac syncope
26
What is classified as an reflex/ neural mediator based syncope ( there are 2 - what are they )
1)Vasovagal Syncopy which there is **3** orthostatic vasovagal, emotional vasovagal, situational vasovagal 2) carotid sinus syndrome
27
What is vasovagal Syncopy - pathophysiology **hint there are 3**
Vasovagal Syncopy is LOC due to temporary loss of blood supply to the brain 1) orthostatic vasovagal due to position change ( commonly standing up) 2) emotional vasovagal due to pain or fear 3) situational vasovagal on specific actions ( swallowing deficacating coughing or microruation )
28
What is syncope due to orthostatic hypotension **hint there's 3** Bonus point what is vasovagal orthostatic hypotension
Vasovagal orthostatic hypotension due to position change **But** 1)Volume depictions = hemmorage/ D&V 2) drug induced - diuretic or vasodilation 3) autonomic failure - primary is old age or Parkinson diseases or secondary due to spinal injurys or diabetes
29
What are the cardiac causes of syncope **Hint they are 3**
1)**Heart Structural defects** 2)**Arrhythmia** 3)**Great vessel defect** 1) valvular problems ( stenosis ), hypotrophy or myocardial infarction 2) tachycardia eg PVT/ SVT **or** Bradycardia 3) AAA, PE, Aortic dissection
30
What can you check in your history or assessment which will aid in the impression of vasovagal Syncopy
History - spefic trigger of pain, emotions, or swallowing pooing Clinical signs of pallor, nausea,**PT recognises they're going to faint** = try to hold something
31
What can you check in your history or assessment which will aid in the impression of orthostatic hypotension based Syncopy
History = dizziness on standing Reduced fluid intake or history of D&V Any drug ingestion 2) assessment of postural drop of 20 systolic or 10 diastolic from sitting to standing
32
What can you check in your history or assessment which will aid in the impression of cardiac syncope
History - chest pain, ACS pain, history of random **DROP** won't try to catch themselves 2) ECG, feel for apex beat, auscultation of heart sounds
33
What is Parkinson's disease 1) pathophysiology 2) signs and symptoms 3) treatment
1) an irreversible condition whereby there's a **degeneration of neurons** within the **substantia Niagara** ( par compactor) whom responsible for send **signals**l to strium thus the **release of dopamine** this stimulates Cortex thus **movement** Tremor - resting due to imbalance ( no weakness tho) Cogwheel Rigidity - like a robot stop start
34
What is Wernicke encephalopathy 1) pathophysiology 2) command symptoms ❄️❄️❄️ 3) treatment plan
1) reduction in thyamine (destroyed liver = no storage, destroyed intestines = no absorption, no activation of thymine = reduction of glucose to brain 2) stride ( wide short paced gate = ataxia ), nystagmus ( cn6) , oblivious ( delirium, disorientated) 3) combat for IV thamine to prevent Wernicke Korsakoff syndrome
35
Wernicke Korsakoff syndrome 1) pathophysiology 2) command symptoms 3) treatment plan
1) chronic Wernicke encephalopathy due to reduced thyamine = neurons degeneration. 2) psychosis, amnesia ( old or new memory's ) causing **confabulation ( making up story to fill gaps ) 3) convay for thyamine
36
What is alcohol withdrawal 1) pathophysiology 2) command symptoms 3) treatment plan
1) alcohol enhances gaba ( depressing) = prolonged usage = body overstimulates to antipate alcohol = no alcohol result withdrawal 2) agitation, deletium, tremors, clamminess, seizures, reduced GCS 3) convey
37
What are the warning signs for severe alcohol withdrawal
- **Seizures** - Tachtile disturbance( crawling ) - visual ( hallucinations) - **tremors** - severe agitation **Any alcohol + head injury**
38
Any patient who is drunk - what should you do and what **must** you **consider** and **check**
- Consider any risk for head injury causing symptoms or exaccibating - can PT maintain airway If sure there's **no head injury** and you have **checked** then discharge in care of **responsible adult** or **convey**
39
How can you diagnose incomplicated vasovagal Syncopy
**3 p's** - posture ( prolong standing or feeling of fainting - provoking factors ( eating vomiting, pain, fear, medical procedure) - prodromal( sweating or hot before loc)
40
What are the 3 assessments you must conduct for patient with an LOC
-H2t -12 lead ECG - BP ( INDCUDING POSTRAL DROP) - mobility test
41
What is the difference between a generalised and focal seizures
1) generalised = affect both hemisphere 2) focal seizures = one hemisphere
42
What are the different types of focal seizures
Simple Complex partial focal seizures = lack of awareness
43
What is an absent seizure 2) what types of seizures is it 3) signs and symptoms 4) command duration
Fixed body state - eyes open ( staring blankely ) - unconscious
44
What is a tonic seizure 2) what types of seizures is it 3) signs and symptoms 4) common duration
1)Tonic - stiffening of the muscles 2) generlised epileptic 3)muscle stiffening, back arching, cyanosis, ictal cry - cry just before (air leaves by lungs), ? Fall backwards 4) less than 1 minute
45
What is a myotonic seizure 2) what types of seizures is it 3) signs and symptoms
1) muscular spasms 2) generalised epileptic 3) rapid full body shaking - lasting few seconds - PT maybe awake
46
What is a complex partial focal seizure 2) what types of seizures is it 3) signs and symptoms
**conscious/non - maybe aware** -Lips smacking - picking up and dropping stuff - chewing - plucking at clothes - rapid blinking - muscle jerking
47
What is a simple focal seizure 2) what types of seizures is it 3) signs and symptoms
Focal epileptic seizure = one sided **patient will be awake + symptoms= aura ** - pins and needles - strange smell / taste - localised muscle jerking ( may turn to jacksonial march
48
What is encephalitis
49
What is Cushing traid - why is Cushing traid important/show
**Bradycardia + irregular resps + hypertension** Major trauma to the brain = signs of increased ICP
50
Absence seizures 1) command symptoms 2) seizure type
1) eyes staring, eyelids fluttering, fixed eyes 2) generalized epileptic
51
What are the basic questions need for an loc
Prior - general circumstances (sitting, activity) + any symptoms ( fear, fever , sweating, colour, palandrome) During - seizure activity, fall how, duration of loc Post - recovery period quick, confusion, any prior loc
52
What is multiple sclerosis (MS)
It's the demyelination of central nerves caused by inflammation due to autoimmune of antigen mimicry post infection - Blood brain barrier overcome but repairs at first instance. Inflammation causes plaque formation on white matter predominantly.
53
What are 2 key observations need to be ruled out to identify a stroke
Temperature and blood glucose
54
What is the MRC scale Test for power goes up to 5 ? Stroke patient
1) no visable movement 2)visaable contraction but no movement 3)limb move but not against gravity 4)limb moves against some resistance 5) full power
