30
Q

What is SNOOP?

A

S-Systemic symptoms, illness, or condition
N-Neurologic symptoms
O-Onset is new (particularly for age 40)
O-Other associated conditions
P-Previous headache history with headache

No SNOOP-NO IMAGING

31
Q

Migraine

A

More prevalent in women. Characterized by recurrent moderate to severe headaches that are pulsatile in nature.
Vasodilation to be the rebound of an initial vasoconstriction
neuro-vascular theory several neurotransmitters (dopamine, nitric oxide) and inflammatory markers potentiate irritability of the brain. NEUROGENIC INFLAMMATION IS RESPONSIBLE FOR PAIN.

32
Q

S/S of Migraines

A

Unilateral, throbbing or pulsatile headache. N/V photophobia. Recurrent attaches. Genetic. AURA.

33
Q

Risk of stroke and Migraine

A

Migraine w/aura= stroke x2

Migraine w/aura+smoking+oral contraceptives=stroke riskx7

34

STRESS
MENSTRUATION
sleep disturbances
food

35
Q

Treatment for a Mild-moderate Migraine.

A

NSAIDS, Acetominophen, +/- antiemetic with caffeine (Excedrin)
with short acting barbiturate (Fioricet).

36
Q

Treatment for a Moderate-Severe migraines

A

Triptans (Sumatriptan, zolmitriptan)
Selective agonist for serotonin (causes arterial vasoconstriction)
Ergots (Erotamine, dehydroertamine) weak arterial vasoconstrictor, LESS EFFECTIVE THAN TRIPTANS, but last longer

37
Q

Prophylactic treatment for migraines

A 
Prophylactic treatment
BB: propanolol, metoprolol
CCB: verapamil
Antidepressants: amitriptyline
Anticonvulsants: valproate

Pt w/hx of HTN-BB,CCB
Pt w/hx of arrhythmia-BB,CCB
Pt. w/ depression-antidepressants
Pt. w/ obesity-topiramate

Women childbearing age- DO NOT PRESCRIBE anticonvulsant, esp VALPROATE
MAY TAKE VERAPAMIL
