Origin: The most common cause of migraines/headaches can relate to neck complications. From spending excessive time looking down at a laptop, desktop, iPad, and even from constant texting, an incorrect posture for extended periods of time can begin to place pressure on the neck and upper back leading to problems that can cause headaches. The majority of these type of headaches occurs as a result of tightness between the shoulder blades, which in turn causes the muscles on the top of the shoulders to also tighten and radiate pain into the head.
Arteriovenous malformations and expanding aneurysms
Lupus cerebritis
Venous sinus thrombosis
Cervical fracture or malformation
Fracture or dislocation
Occipital neuralgia
Vertebral artery dissection
Chiari malformation
Metabolic
Hypoglycemia
Hypercapnea
Carbon monoxide
Anoxia
Anemia
Vitamin A toxicity
Glaucoma
Subarachnoid Hemorrhage
Usually due to ruptured aneurysm
Sudden onset of severe pain
Often vomiting
Patient appears ill
Often nuchal rigidity
Refer for CT and possibly lumbar puncture
Meningitis
Patient appears ill
Fever
Nuchal rigidity (except in elderly and young children)
Refer for lumbar puncture – diagnostic
Neoplasms
Unlikely cause of HA in average patient population
Mild and nonspecific head pain
Worse in the morning
May be elicited by vigorous head shaking
If focal symptoms, seizures, focal neurologic signs, or evidence of increased intracranial pressure are present rule our neoplasm
Subdural Or Epidural Hemorrhage
Due to hypertension, trauma or defects in coagulation
Most often occurs in the context of acute head trauma
Onset of symptoms may be weeks or months after an injury
Differentiate from the common post-concussion headache
Post-Concussive HA may persist for weeks or months after an injury and be accompanied by dizziness or vertigo and mild mental changes, which will all subside
Exquisite tenderness and/or swelling over the temporal or occipital arteries
Evidence of arterial insufficiency in the distribution of branches of the cranial vessels
High ESR
Cervical Region HA
Neck trauma or with symptoms or signs of cervical root or cord compression
Order MR or CT cord compression due to fracture or dislocation
Cervical instability
Order cervical spine x-rays lateral flexion and extension views
Ruling Out Dangerous HA
Rule our history of serious head or neck injury, seizures or focal neurologic symptoms, and infections that may predispose to meningitis or brain abscess
Check for fever
Measure blood pressure (concern if diastolic >120)
Ophthalmoscopic exam
Check neck for rigidity
Auscultate for cranial bruits.
Complete neurologic examination
If needed order complete blood cell count, ESR, cranial or cervical imaging
Episodic Or Chronic?
<15 days per month = Episodic
>15 days per month = Chronic
Migraine HA
Generally due to dilation or distension of cerebral vasculature
Serotonin In Migraine
AKA 5-hydroxytryptamine (5-HT)
Serotonin becomes depleted in migraine episodes
IV 5-HT can stop or reduce severity
Migraine With Aura
History of at least 2 attacks fulfilling the following criteria
One of the following fully reversible aura symptoms:
Visual
Somatic sensory
Speech or language difficulty
Motor
Brain stem
2 of the following 4 characteristics:
1 aura symptom spreads gradually over ≥5 min, and/or 2 symptoms occur in succession
Each individual aura symptom lasts 5-60 min
1 aura symptom is unilateral
Aura accompanied or followed in <60 min by headache
Not better accounted for by another ICHD-3 diagnosis, and TIA excluded
Migraine Without Aura
History of at least 5 attacks fulfilling the following criteria:
Headache attacks lasting 4-72 h (untreated or unsuccessfully treated)
Unilateral pain
Pulsing/pounding quality
Moderate to severe pain intensity
Aggravation by or causing avoidance of routine physical activity
During headache nausea and/or sensitivity to light and sound
Not better accounted for by another ICHD-3 diagnosis
Cluster Headache
Severe unilateral orbital, supraorbital and/or temporal pain
“Like an ice pick stabbing me the eyeâ€
Pain lasts 15-180 minutes
At least one of the following on the side of headache:
Conjunctival injection
Facial sweating
Lacrimation
Miosis
Nasal congestion
Ptosis
Rhinorrhea
Eyelid edema
History of similar headaches in the past
Tension Headache
Headache pain accompanied by two of the following:
Pressing/tightening (non-pulsing) quality
“Feels like a band around my headâ€
Bilateral location
Not aggravated by routine physical activity
Headache should be lacking:
Nausea or vomiting
Photophobia and phonophobia (one or the other may be present)
History of similar headaches in the past
Rebound Headache
Headache occurring on ≥15 days a month in a patient with a pre-existing headache disorder
Regular overuse for >3 months of one or more drugs that can be taken for acute and/or symptomatic treatment of headache
Due to medication overuse/withdrawal
Not better accounted for by another ICHD-3 diagnosis
