Headache 2 Flashcards
What are some causes of secondary headache disorders
- trauma/injury to the head/neck
- cranial/cervical vascular disorders (blood vessels)
- non vascular intracranial disorders (intracranial masses)
- substance abuse/withdrawal
- disorder of eyes (uveitis), sinuses, teeth, mouth or other facial/cranial structures (TMJ).
Secondary headache occurs in association with a definable abnormality:
- structural
- vascular
- toxic
- inflammatory
- infectious
- may mimic a primary headache disorder. Requires prompt work up.
Headache caused by trauma is one of the most common causes of secondary headache. Presents within ____ months of injury and can persist. Usually resembles tension or migraine headaches. It is never due to intracranial bleed from trauma
3
What are some additional symptoms of headaches that are caused by trauma to head/neck
- dizziness
- fatigue
- reduced ability to concentrate
- mild memory problems
- insomnia
- irritabilty
What is the pathogenesis of headaches caused by trauma?
unclear, may be due to:
- axonal injury
- alteration in cerebral metabolism
- psychopathology: patient expectation of dev headache after injury
- malingering: uncommon cause
how do you manage headache caused by trauma
- neuroimaging to rule out structural abnormality
- carotid artery dissection: med ER
- intracranial hematoma: med ER
What is an optometrists role in managing headaches due to trauma
- rule out ocular sequelae of trauma (retinal tear, RD, etc)
- refer to neurology for management
What types of disorders cause headaches due to cranial/cervical vascular disorders
- ischemic stroke
- hemorrhagic stroke
- arterio-venous malformation
- cerebral venous sinus thrombosis
- arterial dissection
- giant cell arteritis
Headache in ischemic stroke is a self limited course. Dev’s in close temporal relation to other symptoms and signs of ischemic stroke. Neurologic symptoms predominate:
- loss of consciousness
- motor weakness
- altered mental status
Headache in hemorrhagic stroke is usually due to _____hemorrhage. it involves an abrupt and severe thunderclap headache. mortality is 40-50%. 50% of survivors are left disabled. Requires STAT non contrast CT: neuro surgical ER to identify site of ruptured aneurysm, and repair aneurysm.
subarachnoid
______space is not a real space but it can fill with blood. acute but not as severe as subarachnoid hemorrhage. in elderly its usually associated with history of falling. may lead to permanent neurologic deficits if left untreated. Occurs as a tear of a bridging veiln.
subdural
Headache secondary to arteriovenous malformation may present as ____ HA, chronic paroxysmal hemicrania, or migraine. Other features present include seizure disorder, and focal neurologic deficits. Requires neuroimaging to diagnose.
cluster
How do you differentiate headaches secondary to arteriorvenous malformation from primary HA disorders?
- abrupt onset
- falls out of patient demographic for particular primary HA
- associated neurologic symptoms
- associated retinal findings.
Headache is the most common symptom of ____ sinus thrombosis. associated with other signs of elevated ICP. Requires MRI and ____ for diagnosis. Treatment requires ____ followed by 6+ month course of oral anticoagulation
venous; MRV; heparin
Headache secondary to artery dissection is sudden and severe, ipsilateral to artery dissection. HA is usually persistent and can last up to 4 days in duration. If suspected requires, STAT MRI and ____ of head and neck and prompt surgical intervention. If cervical arteries involved, may present with ______
MRA; horners
