These medications are first-line treatment for moderate to severe migraine attacks.
Triptans
This is the maximum time from symptom onset to administer IV alteplase (tPA) in eligible patients.
4.5 hours
A hyperdense lesion on non-contrast CT within the first 24 hours typically indicates this stroke type.
hemorrhagic stroke
Where does blood accumulate in epidural hematomas?
Between the skull and dura mater
This condition may mimic stroke but is actually caused by demyelination and shows periventricular lesions on MRI.
Multiple Sclerosis
This type of headache often feels like a tight band around the head and is the most common primary headache.
Tension-type headache
What is the treatment for idiopathic intracranial hypertension (pseudotumor cerebri)?
Carbonic Anhydrase Inhibitor (Acetazolamide)
The following image shows what? (Specific)
Left-sided Ischemic Stroke
What are the three main features of Cushing's reflex?
Hypertension, bradycardia, and irregular breathing
This region between two arterial territories is most vulnerable to hypotension-related infarcts.
Watershed Area
The presence of both photophobia and phonophobia during a headache episode suggests this diagnosis.
Migraine
This migraine abortive class acts as 5-HT₁B/1D agonists, causing cranial vasoconstriction and inhibition of trigeminal neuropeptide release.
Triptans
A normal head CT with xanthochromia on lumbar puncture would suggest what?
Subarachnoid Hemorrhage
In stroke due to a cardioembolic source like atrial fibrillation, this imaging test is often used to look for thrombus.
transesophageal echocardiogram (TEE)
The middle cerebral artery most commonly supplies this part of the motor cortex.
face and upper limb
This neuropeptide, released during migraine attacks, plays a central role in neurogenic inflammation and vasodilation.
calcitonin gene-related peptide (CGRP)
Prolonged hyperventilation reduces ICP by lowering PaCO₂ but may worsen ischemia by this mechanism
cerebral vasoconstriction leading to reduced cerebral blood flow
What type of hematoma is this?
Subdural hematoma - concave
What herniation is displacement of the medial temporal lobe, from the middle fossa, across the tentorial opening and into the posterior fossa?
Uncal Herniation
This vascular complication involves small vessels in the basal ganglia, often due to chronic hypertension.
Charcot-Bouchard microaneurysm rupture
These autonomic symptoms, like lacrimation and nasal congestion, often accompany cluster headaches.
ipsilateral parasympathetic symptoms
What antibiotic is known to have drug-drug interactions with sumatriptan
Linezolid
A lucid interval following transient loss of consciousness is a hallmark finding in which hemorrhagic condition
Epidural hematoma
Lateral medullary syndrome includes hoarseness, dysphagia, and Horner syndrome, due to infarction in this vascular territory.
posterior inferior cerebellar artery (PICA)
A stroke here may result in "locked-in syndrome."
Pons (Basilar Artery Occlusion)
