Chapter 5 TF

Embolism causes strokes due to the rupture of a blood vessel in the brain.

For underwriting purposes, embolic strokes are treated differently than ischemic strokes.

Vertebrobasilar strokes mainly affect areas like the cerebellum, basal ganglia, or hippocampus.

Transient Ischemic Attack (TIA) is considered a cerebrovascular event.

The incidence of Multiple Sclerosis among siblings is approximately 3%.

Subarachnoid hemorrhage is associated with symptoms like photophobia and nausea.

In a lumbar puncture, a needle is inserted into the spinal canal to extract blood.

Elevated CSF pressure can be a sign of venous thrombosis.

Evoked response tests measure chemical reactions in the brain.

In a normal muscle, there is electrical activity at rest.

Carotid Artery Stenosis can be caused by dyslipidemia and smoking.

Stroke through the carotid arteries in the neck can be reversible, as in a TIA.

The autonomic nervous system is responsible for controlling processes in the body that are under voluntary control.

There are three parts to the autonomic nervous system.

Physical Examination is not considered an important diagnostic technique for neurological disorders.

Computerized tomography (CT) scanning is also known as Computerized Axial Tomography.

Computerized Tomography Angiography uses radiation to highlight blood vessels.

A Coma and Vegetative State are considered physical symptoms that can be tested through mental status examination.

The central nervous system is connected to sensory receptors and muscles by synapses called neurotransmitters.

The cerebellum is part of the hindbrain and coordinates movement.

Memories are not stored in the cerebral cortex according to the text.

The peripheral nervous system consists of the somatic and autonomic systems only.

The medulla oblongata is part of the forebrain.

Gray matter in the nervous system is covered by myelin.

Viral meningitis may present symptoms such as severe headache, photophobia, nausea, and vomiting, but not seizures.

Hydrocephalus causes the ventricles to shrink, allowing normal brain tissue to expand.

Hemiparesis is a common symptom in diseases like carotid artery stenosis and transient ischemic attacks (TIAs).

Bladder incontinence is reported in 22% of cases with symptoms like depressive symptoms and inability to walk unassisted.

Independent individuals can transfer from bed to chair without assistance.

Wheelchair independent individuals may use aids like a stick or cane but can still walk over 50 yards without assistance.
