1
Q

Ischemia of cerebral tissue with sequelae that may include paralysis, weakness, speech defects, and/or sensory changes that last more than 24 hours is:
1. cerebrovascular accident
2. migraine
3. epilepsy
4. transient ischemic attack

A

cerebrovascular accident

A cerebrovascular attack (CVA), or stroke, is an ischemia of cerebral tissue whose sequelae last for more than 24 hours. The mechanism of a transient ischemic attack (TIA), or mini-stroke, is the same as a CVA, but the sequelae disappear within 24 hours. A migraine is also a vascular condition. Epilepsy is a nondegenerative seizure disorder.

Q

A group of disorders characterized by recurrent seizures, sensory disturbances, abnormal behavior, and/or loss of consciousness is:
1. Bell palsy
2. Huntington chorea
3. polyneuritis
4. epilepsy

A

epilepsy

Epilepsy is a group of disorders, all of which involve an abnormal discharge of electrical activity from the nerve cells of the cerebrum. Sudden, uncontrolled bursts of activity from the neurons characterize a seizure, or convulsion. Seizures can cause sensory disturbances, involuntary muscle contractions, and loss of consciousness.
