Headaches & Tumors Flashcards
Describe the origin points of headaches
- extracranially (skin, muscle, vessels, periosteum)
- intracranially (vessels, dura, falx cerebri)
- brain parenchyma is incapable of producing pain
Describe the red flags in headache eval
- first severe HA or worst HA of life with acute onset
- HA progressively worsening over days/weeks
- severe HA with fever
- nuchal rigidity
- decreased LOC or focal neuro signs
Describe the onset and epidemiology of migraines
- onset usually adolescence or young adulthood (childhood too)
- female 3:1 male
- most commonly without aura
Describe the 2 types of migraines
Common Migraine (without aura)
Classic Migraine (with aura before or after HA)
Describe some of the precipitating factors of migraines
- menstruation
- too much/little sleep
- red wine, cheese, chocolate, herring, processed meats, caffeine
- meds
Describe the symptoms of a migraine
+/- aura
- unilateral
- pulsating/throbbing
- nausea/vomiting
- moderate to severe
- worse with activity
- photo/phonophobia
Describe the types of migraine auras
- Visual (scotoma)
- Sensory (unilateral paresthesia, numbness)
- Motor (unilateral weakness, aphasia)
What is the diagnostic threshold for migraines
- 5+ attacks before diagnosis made
- photo/phonophobia, impairment, nausea
What is the potential pathophysiology of a migraine
- intense vasoconstriction of cranial vessels
- issue with serotonin
Describe some of the prophylactic treatment for migraines
- beta blockers (propranolol)
- calcium channel blockers
- SSRIs (fluoxetine)
- TCAs (amitriptyline)
- ASMs (valproic acid)
Describe some of the abortive therapies for migraine
- OTC analgesics
- vasoconstrictors (ergots)
- antiemetics
- serotonin agonists (sumatriptan)
- IV/IM NSAID (ketorolac/toradol)
Describe the characteristics and pathophys of a cluster headache
series/cluster of headaches over 2-3 months with clusters occurring every 1-2 years
dilation of retro orbital blood vessels and inflammation of trigeminal nerve branches
Describe the clinical presentation of cluster headaches
- excruciating penetrating unilateral non-throbbing pain in trigeminal nerve distribution
- usually behind an eye
Describe the treatment of cluster headaches
similar to migraines
- first line sumatriptan
- oxygen inhalation effective in 70%
- beta blockers not used
What might trigger cluster headaches
- alcohol
- histamines
- nitroglycerine
Describe the autonomic features associated with cluster headaches
- lacrimation
- conjunctival injection
- rhinorrhea
- ptosis/miosis
What is the most common type of headache
tension headache
What is the etiology of tension headaches
- episodic or chronic
- can last 30 mins to 7 days
Describe the clinical presentation of a tension headache
- bilateral occipital, nuchal, frontal, pressure/tightness/band like pain
- unaffected by activity
+/- photo/phonophobia - no n/v or throbbing
Describe the treatment for tension headaches
- OTC analgesics (ASA, APAP, NSAIDs)
- excedrin
- stress reduction
- prevention (antidepressants or ASMs)
Describe sinusitis
acute or chronic infection of sinus cavities
