What makes up the autonomic nervous system?
Sympathetic and parasympathetic nervous system
What is the parasympathetic nervous system responsible for?
Conserving energy and the body's resources
What is the sympathetic nervous system responsible for?
Catecholamine release - Epinephrine
Mobilizing energy stores and decreasing release of insulin
Redistributing blood low - Increasing to muscles and lungs (flight) and decreasing to
GI/Integumentary
What are the classifications of primary brain injury?
Focal or diffuse
What are focal brain injuries?
Specific, grossly observable lesions that occur in a precise location
What are examples of focal brain injuries?
Epidural hemorrhage and subdural hemorrhage
What are examples of diffuse brain injuries?
, Hypoxia, meningitis, encephalitis, and damage to blood vessels
What can happen with increased intracranial pressures?
Collateral dysfunction such as Diabetes Insipidus
What are characteristics of autonomic hyperreflexia?
Paroxysmal hypertension, pounding headache, blurred vision, sweating above level of
lesion with flushing of skin, nasal congestion, nausea, piloerection causes by pilomotor
spasm, and bradycardia.
What is the sequence of events leading to hyperreflexia induced bradycardia?
Stimulation of the carotid sinus nerve to the sinoatrial nose
The intact autonomic nervous system reflexively responds with arteriolar spasm that
increases blood pressure
Baroreceptors in the cerebral vessels, carotid sinus, and aorta sense the hypertension
and stimulation the parasympathetic nervous system
The heart rate decreases, but the visceral and peripheral vessels do not dilate because
efferent impulses cannot pass through the cord
What are the onset of delirium and dementia?
Delirium - acute and common during hospitalization
Dementia - usually insidious and can be acute in situations such as trauma or stroke
What conditions are associated with delirium?
