Severe drops in blood pressure can lead to fainting, with a possibility of injury. Moderate drops in blood pressure can cause confusion/inattention, delirium, and episodes of ataxia. Chronic orthostatic hypotension is associated with cerebral hypoperfusion that may accelerate the pathophysiology of dementia. [5]
The number of events that can lead to the development of PSH symptoms is many. The exact pathways or causes for the development of the syndrome are not known. Traumatic brain injury , hypoxia, [ 4 ] stroke , anti-NMDA receptor encephalitis (although further associations are being explored), [ 5 ] injury of the spinal cord , [ 1 ] and many other ...

Other kinds of dysautonomia may coexist, e.g., postural orthostatic tachycardia syndrome (POTS) is common with this condition, orthostatic hypotension with the BP going both high and low at times due to autonomic dysfunction; Type 2 diabetes [1] Vascular adrenergic hypersensitivity: Orthostatic hypertension can be secondary to this [14]
