Study Notes

Autonomic Dysfunction

Inspiration increases heart rate.
The Valsalva maneuver is a useful test to diagnose autonomic control of blood pressure.
A common symptom of autonomic dysfunction related to urination is urinary retention.
A symptom of autonomic dysfunction related to heat intolerance is heat stroke.
A symptom of autonomic dysfunction related to digestion is gastroparesis.
Fainting in autonomic dysfunction is caused by a lack of blood flow to the brain due to abnormal blood pressure regulation.
Physical therapy, medications, and lifestyle changes can correct some of the problems associated with autonomic dysfunction.
Changes in heart rate and blood pressure are triggered by the autonomic nervous system (ANS).
A symptom of autonomic dysfunction related to cardiovascular problems is orthostatic intolerance.
Standing increases heart rate and blood pressure due to the autonomic nervous system's response to gravity.
A symptom of autonomic dysfunction related to male reproductive health is erectile dysfunction.
A symptom of autonomic dysfunction related to pupil reaction is abnormal pupillary response.

Autonomic Neuropathy

The most common cause of autonomic neuropathy is diabetes.
Traumatic brain injury is an example of a type of injury that elicits adaptations in autonomic nervous system control.

Autonomic Nervous System Control

When there is a loss of homeostatic control in temperature and blood pressure, hyperthermia and hypotension occur.
The integrative response to preserve temperature and blood pressure involves the autonomic nervous system, hypothalamus, and vasomotor center.
Blood brain leakage can cause an increase in systemic blood pressure due to the release of vasoactive substances.

Diseases and Autonomic Dysfunction

Guillian-Barré syndrome is an autoimmune disease that can rapidly affect autonomic nerves.
The most common symptom of autonomic dysfunction is orthostatic intolerance.
Vasopressor medication is aimed at overcoming autonomic failure in the treatment of sepsis.
Bacterial release of endotoxins promotes systemic illness and ANS instability.
Type 2 diabetes is an endocrine disease of insulin resistance and hyperglycemia that can lead to autonomic neuropathy.
Subarachnoid hemorrhage promotes an increase in intracranial pressure and pulmonary edema.
Diabetic autonomic neuropathy promotes autonomic insufficiency in diabetic patients.
