numbness (sensory disturbance)
27
in focal seizures, in the occipital lobe, what symptoms would you experience?
lines and flashes (visual disturbance)
28
what are generalised seizures?
epileptic seizures that occur due to simultaneous abnormal activity in multiple parts of the brain
29
is there LOC in generalised seizures?
LOC occurs immediately
30
what can trigger generalised seizures?
flashing lights | sleep deprivation
31
what happens during the tonic phase of tonic colonic seizures?
patients falls to the ground and becomes rigid and cyanosed as they stop breathing

during which phase would tongue biting and incontinence occur in a tonic-colonic seizure?
tonic phase
33
what it the colonic phase in a tonic-colonic seizure?
asymmetrical convulsive jerks eyes roll into back of head start breathing again

what are atonic seizures?
sudden loss of all muscle tone with maintenance of consciousness
39
how do you diagnose epilepsy?
clinical diagnosis
