DDx- headache Flashcards
What are the ‘Do Not Miss’ of HA aka Secondary Causes?
SAH, Meningitis (infection), Temporal Arteritis, Glaucoma, HTN, Cerebral ischemia/CVA/TIA, Arterial Dissection, and Brain Tumor, also space occupying lesion.
What is SNOOP?
Systemic symptoms of dz, Neurological, Onset- sudden thunderclap, Onset- before age 5 or before age 50, Pattern change- progressively worse or waking up from sleep
What are the Primary Headaches?
Tension-type headache
Migraine
Cluster
Associated with exercise
Patterns for Primary Headaches
Positive family history Stereotypic headache pattern over time Menstrual association Mutation (marker) on chromosome 19 Prodromes and/or auras Resolution with sleep Changing locations of headache Otherwise healthy individual
Most common type of primary headache? What class does it fall under? What is the etiology?
Tension headache. Extracranial. Muscle strain/stress.
IHS Criteria for Tension HA?
*At least 10 previous headache episodes lasting from 30 minutes to 7 days characterized by at least 2 of the following pain characteristics:
-Pressing, tightening, nonpulsatile quality
-Mild or moderate intensity (may inhibit but does not prohibit activity)
-Bilateral location
-Not aggravated by routine physical activity
And one of the following:
No nausea or vomiting
Photophobia or phonophobia may be present, but not both
IHS Criteria for Migraine Without Aura
Headache lasting 4-72 hours characterized by at least two of the following four characteristics: Unilateral pain Throbbing, pulsatile quality Moderate to severe in intensity Aggravation by routine activity And at least one of the following: Nausea and/or vomiting Photophobia and/or phonophobia Diagnosis should include at least 5 previous attacks and no evidence of underlying disease
Etiology of Migraine Without Aura
No longer thought of as a vascular problem
Neurovascular Theory:
Hyperexcitable state of the cerebral cortex with subsequent vasuclar epiphenomenon of dilation and constriction: Cortical spreading depression
IHS Criteria for Migraine With Aura
Headache follows attacks, with at least 3 of the following:
1 or more reversible visual symptoms (either positive or negative features) and/or sensory or speech problems
At least 1 aura symptom develops gradually over more than 4 minutes or 2 or more symptoms occur in succession
No aura symptom lasts more than 60 minutes
Headache follows aura with a free interval of less than 60 minutes (may also begin before or simultaneously with aura)
What serious life-threatening event is more common with Migraine with Aura?
Stroke x4
When are Triptans (for pain) contraindicated? (5-HT1B serotonin receptors)
Contraindicated in coronary vascular disease or uncontrolled HTN**
Cluster HA etiology?
Not clearly understood- Trigeminal autonomic cephalgias
ISH Criteria for Cluster HA- rarest
**Autonomic characteristics are telling
Individual episode of unilateral headache lasting 15 minutes to 1 hour, occurring up to several times a day for periods of 3 to 16 weeks
May resolve for months to years and then occur again
May have seasonal variations
Pain originates behind or around the eyes and may radiate into temple, jaw, nose, teeth or chin; drooping eyelid, tearing eye; facial flushing, nasal congestion
Usually no nausea or vomiting
Restlessness and agitation
Cluster HA Risk Factors?
Alcohol use Heavy smoking Cold wind exposure Heat blown into the face Seasonal variation
Tx for Cluster HA?
Acute: High-flow oxygen – 10 L/min for 10 min *Oral medications usually ineffective Injectable triptan DHE intranasal Lidocaine intranasal Non-Acute: Ace inhibitors Corticosteroids – high dose Anti-seizure medication
When is Neuroimaging Indicated?
Nonacute headache and an unexplained abnormal finding on neurological examination
Red flag symptoms (SNOOP)
Onset after age 50 years
Headache that is progressively getting worse
Immunocompromised with headache and no fever - MRI
**Not indicated for Tension HA
Neoplasm S/Sx & PE
Headaches – most commonly bilateral, frontal, and intermittent
Recent worsening of symptoms
N/V
PE:
Exacerbated by postural changes
Full ophthalmoscopic exam (increased ICP)
Rebound HA S/Sx
Signs/Symptoms:
Typically occur in pts with underlying headaches that transforms to a chronic daily headache d/t excessive intake of headache relief medication (Imitrex)
Can also be caused by other foods, caffeine, etc
Simple Partial Seizure
Unilateral sensory and motor symptoms. Gustatory and visual hallucinations, nausea.
Get MRI- rule out space occupying lesion/ Cancer Mets
EEG
**Imitrex may induce
Treatment: Migraine with Aura?
Prophylaxis: -Amitriptyline 15 mg/d -Naproxen 500 mg q 12hr -Gapapentin Abortive: -Imitrex
What are Secondary HA and what are they?
Symptom of a disease that can active the pain sensitive nerves of the head. Brain tumor Medicine rebound headache Orthostatic hypotension Meningitis
JR is a 46-year-old left handed male with a 5 month history of headache. He describes the headaches as bitemporal, throbbing and lasting from a few minutes to an hour in duration. The current frequency is 3 headaches a week for the past 5 months. The headaches are not associated with photophobia, phonophobia, or vomiting. They are not worsened with movement. After the symptoms resolve he does feel nausea occasionally. He does report episodes of visual and sensory disturbances prior to the headaches beginning. He notes it typically begins with a metallic taste in his mouth followed 20 minutes later by a visual disturbance of “looking through water”. He also has tingling of his left hand and left side of his tongue for 5-15 minutes followed by numbness in his left leg with no ambulatory difficulty. He has had headaches for 15 years that have been triggered by excessive coffee or alcohol (beer). The numbness and tingling have been new although he describes an episode, a year ago, where he had slurred speech and tingling in his left hand and tongue only lasting a few minutes. He reports no weakness associated with that episode. He takes Imitrex as needed for the headaches and rests until they resolve. DDX?

HA Key Points
HEADACHE DISORDERS ARE AMONG THE MOST COMMON DISORDERS OF THE NERVOUS SYSTEM
.-IT HAS BEEN ESTIMATED THAT 47% OF THE ADULT POPULATION HAVE HEADACHE AT LEAST ONCE WITHIN LAST YEAR IN GENERAL.
-HEADACHE DISORDERS ARE ASSOCIATED WITH PERSONAL AND SOCIETAL BURDENS OF PAIN, DISABILITY, DAMAGED QUALITY OF LIFE AND FINANCIAL COST.
-A MINORITY OF PEOPLE WITH HEADACHE DISORDERS WORLDWIDE ARE DIAGNOSED APPROPRIATELY BY A HEALTH-CARE PROVIDER.-HEADACHE HAS BEEN UNDERESTIMATED, UNDER-RECOGNIZED AND UNDER-TREATED THROUGHOUT THE WORLD.
