Q

Discuss the pathophysiology of headaches

A
  • Still debated
  • Familial history of migraine
  • Vascular and chemical changes in the brain
  • Changes are in response to stimulus or trigger

Q

Differential diagnosis of Headaches

A

•Primary headache
•Secondary headache
•Headache + neurological signs/symptoms,
systemic symptoms and history of acute onset
or age >50 with a new headache =
EMERGENCY

Q

Abortive treatment for Migraines

A

•NSAIDS, Excedrin Migraine, Acetaminophen
•metoclopramide (Reglan) – helps potentiate absorption and effect. CAUTION in elderly!
•TRIPTANS – caution! Do not use in those with HTN or ASCVD. MOA-
cranial vasoconstriction. Serotonin receptor agonist (5-HT1B and 5-HT1D).
•ERGOT – not first line, cause nausea and potential for rebound headache
•CGRP Inhibitors (GEPANT) – new drugs you may have seen on commercials. Very
expensive and many insurances do not cover.
•Corticosteroids – refractory headache, recurrent headaches, severe headaches. May be given orally in single dose or short-taper dose
