What is the primary difference in definition between a stroke and a Transient Ischemic Attack (TIA)?
A stroke is caused by hemorrhage, while a TIA is caused by ischemia.
A stroke results in neurologic deficits lasting longer than 24 hours or evidence of brain infarction, whereas TIA symptoms resolve within 24 hours without infarction on imaging.
A stroke involves focal vascular causes, while a TIA involves generalized systemic hypotension.
A stroke is defined clinically, while a TIA requires laboratory confirmation.
Globally, what is the rank of stroke (cerebrovascular diseases) as a cause of death?
First.
Second.
Fifth.
Tenth.
Which arteries arise from the proximal Middle Cerebral Artery (M1 segment) and supply deep structures like the putamen, outer globus pallidus, and posterior limb of the internal capsule?
Anterior cerebral arteries.
Posterior cerebral arteries.
Short circumferential arteries.
Lenticulostriate arteries.
Which type of clinical presentation, often without accompanying head pain, is cited as a common stroke mimic that can be particularly difficult to diagnose?
Seizure (complex partial seizures).
Acephalgic migraine.
Intracranial tumor.
Metabolic encephalopathy.
According to recent clinical trials concerning acute Intracerebral Hemorrhage (ICH), what acute systolic blood pressure (SBP) target range has been shown to be safe and possibly beneficial in patients whose initial SBP was 150-220 mmHg?
Below 180 mmHg.
Below 140 mmHg.
Above 200 mmHg.
Between 160 and 180 mmHg.
What is the imaging modality of choice for the initial evaluation of a patient presenting with acute stroke symptoms?
Magnetic Resonance Angiography (MRA).
Diffusion-Weighted Imaging (DWI).
Noncontrast head Computed Tomography (CT) scan.
Conventional x-ray angiography.
What is the most significant cause of cardioembolic stroke worldwide?
Mechanical heart valve replacement.
Nonrheumatic (nonvalvular) atrial fibrillation.
Patent foramen ovale (PFO).
Ischemic cardiomyopathy.
In the management of acute ischemic stroke, which neuroimaging sequence is considered the most sensitive for detecting early brain infarction?
T2-weighted fluid-attenuated inversion recovery (FLAIR).
Conventional CT.
Diffusion-weighted imaging (DWI).
CT angiography (CTA).
In patients undergoing endovascular mechanical thrombectomy for acute stroke, what effect does time-to-treatment have on outcome?
The odds of a good outcome are highest if groin puncture occurs within 8 hours.
The odds of a good outcome are independent of time-to-treatment.
The odds of a good outcome exceed 3 if groin puncture occurs within 2 hours of symptom onset.
Treatment must begin within 60 minutes of symptom onset for any measurable benefit.
Which clinical features, if present at onset, are cited as favoring hemorrhagic stroke over ischemic stroke?
Deficit maximal at onset or remits quickly.
Isolated sensory disturbances.
More depressed level of consciousness or higher initial blood pressure.
Symptoms migrating slowly across a limb over minutes.
In the management of cerebellar hemorrhages, surgical evacuation is often required for hematomas exceeding what diameter?
1 cm.
2 cm.
3 cm.
5 cm.
Which of the following is NOT one of the primary components used to calculate the Intracerebral Hemorrhage (ICH) Score?
Age.
Hematoma Volume.
Prior history of stroke.
Glasgow Coma Scale.
What type of cerebrovascular pathology is defined by the deposition of the β-amyloid peptide in the walls of small cerebral arteries, arterioles, and capillaries, commonly leading to lobar hemorrhages?
Arteriolosclerosis.
Cerebral amyloid angiopathy.
Intracranial atherosclerosis.
Fibromuscular dysplasia.
In the posterior circulation, the paired vertebral arteries join together to form which major artery at the pontomedullary junction?
Posterior communicating artery.
Superior cerebellar artery.
Posterior cerebral artery.
Basilar artery.
CT imaging is generally the preferred method for acute stroke evaluation primarily because:
It provides superior visualization of ischemic tissue compared to MRI.
It is highly sensitive and specific for detecting intracranial hemorrhage and is more widely available/logistically easier than MRI.
It allows for definitive diagnosis of all types of stroke mimics.
It can reliably show early brain infarction within the first hour.
