Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system. Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis , and hyperthermia . [ 1 ]
Paroxysmal attacks in various disorders have been reported extensively, and ephaptic coupling of demyelinated nerves has been presumed as one of the underlying mechanisms of this phenomenon. This is supported by the presence of these attacks in multiple sclerosis and tabes dorsalis, which both involve demyelination of spinal cord neurons.
Patients with paroxysmal hypertension who test negative for pheochromocytoma are said to be suffering from a clinical entity called "pseudopheochromocytoma." This disorder is due to episodic dopamine discharge and has been observed predominantly in hypertensive women whose presentation mimicked pheochromocytoma , but with subsequent testing ...
The most favoured hypothesis for the cause of insomnia is the hyperarousal hypothesis, which is known as a collective over-activation of various systems in the body, this over-activation includes the hyperactivity of the SNS. Whereby during sleep cycle disruption sympathetic baroreflex function and neural cardiovascular responses become impaired.

“Symptoms also may not be as bad at night,” Dr. Coleman says. But if you’ve been dealing with a cough for a while, or if it feels like your cough is getting worse, he says it’s time to see ...
The symptoms of a sympathetic pheochromocytoma are related to sympathetic nervous system hyperactivity. [10] The classic triad includes headaches (likely related to elevated blood pressure, or hypertension), tachycardia/elevated heart rate, and diaphoresis (excessive sweating, particularly at night, also known as hyperhidrosis). [7]
The behavioral symptoms are similar to those of an amphetamine, cocaine or caffeine overdose. Overstimulation of the central nervous system results in a state of hyperkinetic movement and unpredictable mental status including mania, rage and suicidal behavior; hyperthermia is also prominently present. [11] Delirium can also be present but rarely.
