emotion
pain
standing too long

Cough
Effort
Micturition

6

[blackouts]: If syncope occurs after minimal stimuation (e.g. head turning) what could be the cause

Carotid sinus syncope

7

[blackouts]: what happens in carotid sinus syncope

hypersensitive baroreceptors = excessive bradycardia and dilation

8

[blackouts]: When might epileptic or stoke-adams blackouts occur which would be uncharacteristic of vasovagal

lying down

9

[blackouts]: blackouts in response to a stereotyped stimulus may indicate

Epileptic

10

epilepsy

11

epilepsy
(possible vasovagal)

12

[blackouts]: post epileptic blackout what might the patient cognition experience

decreased/drowsiness

13

[blackouts]: What is a stoke-adams attack

Transient anrrythmia
(i.e. bradycardia due to complete heart block)

14

[blackouts]: Prior to a stoke adams LOC/blackout what would the patient report

no warning (perhaps palpitations)

15

[blackouts]: length of recovery from blackout in Stoke Adams blackout?

seconds

16

[blackouts]: injury is especially common in which attack

stoke adams

17

[blackouts]: drop attacks usually occur in what demographic (2)

old
women

18

[blackouts]: In a drop attack in which the patient may not get up for hours what maybe the cause

hydrocephalus

24

[blackouts]: If the patient is twitching when LOC does this does not always indicate epilepsy, what is the cause

cerebral hypoperfusion, reflex anoxic convulsion

25

[blackouts]: how can you distinguish between epileptic jerking and twitching from hypoperfusion

Only epileptic jerking has a tonic phase (contraction) prior to the clonic (cyclic relax/contract)

26

[blackouts]: If the patient is 'sleepy' what may be the cause of the drop attack

narcolepsy

27

[blackouts]: ... may cause blackout, but rare in non-diabetics

hypoglycaemia

28

[blackouts]: inadequate vasomotor reflexes can cause ... which causes blackout

orthostatic hypotension

29

Hyperventilation
light headedness

30

[blackouts]: do you LOC in panic attacks

no

choking

[blackouts]: paleness during a flushing post suggests

stoke adams

34

Men
at night

35

[blackouts]: amnesia post LOC suggests

epilepsy

36

[blackouts]: drop attacks may be due to cataplexy. what is this

muscle weakness from strong emotions

37
