contralateral hemiparesis, contralateral homonymous hemianopia, apraxia, and sensory neglect
The following symptoms are caused by a stroke that involves the middle cerebral artery and affects the dominant hemisphere
contralateral hemiparesis, contralateral homonymous hemianopia, dysarthria, and aphasia
following sxs are caused by a stroke involving the anterior cerebral artery
contralateral hemiparesis, mutism, apathy, confusion, and impaired judgment
these sxs are caused by a stroke involving the posterior cerebral artery
contralateral homonymous hemianopia, unilateral cortical blindness, visual agnosia, and memory loss
Computed tomography (CT) and magnetic resonance imaging (MRI) are ____ neuroimaging techniques that provide information on ___________
structural; the brain’s physical structure,
what is deep brain stimulation (DBS) and which issues it is used for
DBS is a surgical treatment for Parkinson’s disease, essential tremor, and dystonia (especially primary dystonia) that involves implanting a device that sends electrical signals to areas in the brain that control movement.
____ seizures don’t cause a loss of consciousness while _____ seizures do impair consciousness.
simple partial; complex partial
The most common type is primary hypertension, which is also known as essential hypertension and is diagnosed when the cause of elevated blood pressure is ____. In contrast, secondary hypertension is diagnosed when the cause is ____.
unknown; known
A progressive loss of dopamine-producing cells in the __________ has been linked to Parkinson’s disease.
substantia nigra

pituitary gland
Restless leg syndrome is associated with __ dopamine levels
low
Pramipexole and ropinirole are ____________
dopamine agonists
Which of the following types of seizures involves a very brief loss of consciousness with a blank stare?

temporal
levodopa is generally considered to be more effective for ____ than for tremor. (parkinsons)
bradykinesia
Bradykinesia is
slowness of movement and speed (or progressive hesitations/halts) as movements are continued.
An _____ occurs when there is blockage in a cerebral artery that is due to a blood clot or piece of plaque.
ischemic stroke
A ____ is due to bleeding that occurs when there is a rupture in a cerebral artery
hemorrhagic stroke
Heat intolerance is characteristic of _____
hyperthyroidism
Insulin overproduction by the __________ can cause a decrease in blood glucose levels and hypoglycemia.
pancreas
_________ is an advanced magnetic resonance imaging (MRI) technique that is used to detect abnormalities in the brain’s white matter,
