Aka autonomic hyperreflexia. Typical in spinal cord injuries. Presents with severe paroxysmal hypertension and increased reflex actions. Damage to the 6th thoracic vertebrae or higher, including cervical injuries. Abnormal cardiovascular response to stimulation of the sympathetic (autonomic) nervous system. Stimulation of visceral organs results in severe bradycardia, systolic hypertension, diaphoresis, "goose flesh", flushing, dilated pupils, blurred vision, restlessness, nausea, severe headache, and nasal stuffiness.

Polyneuritis presents with rapid progression. Inflammation and demyelination of the peripheral nervous system. Ab's attack Schwann cells, causing the sheath to break down. Uninsulated nerve becomes inflamed, cannot propagate an electrical charge, and resulting muscle weakness, tingling, and numbness. Disease begins at the feet and works upwards. Recovery, however, begins at the top and works downwards.
