Understanding Our Diagnoses And Their Differences

[martiz]

I am now reading Primer on the Autonomic Nervous System and Clinical Autonomic Disorders.

The difference between POTS and Neurogenic Orthostatic Hypotension comparing 4 categories (Orthostatic Symptoms, Orthostatic Hypotension, Orthostatic Tachychardia, Standing Norepinephrine)

POTS has Orthostatic Sympotoms of Dizziness, Tremulousness, Palpitations, Nausea, Skn Vasoconstriction, Hyperhidrosis, Chest Wall Pain)

OH only has some dizziness

POTS has some Orthostatic Hypotension

OH has a lot of Orthostatic Hypotension

POTS has Orthostatic Tachychardia

OH does not

POTS has increased or normal Standing Norepinephrine

OH has reduced Standing Norepinephrne

They also discuss the difference between Orthostatic Intolerance (POTS/OH) vs. CFS vs MVP.

they are using the CDC's criteria (which included people with depression and no physical ailments).

"POTS can be differentiated from CFS by the predominance of orthostatic symptoms...CFS is dominated by non-orthostatic symptoms and has many quasi-infectious symptoms.....We recommend that when the features of fatigue predominate, the condition should be designated as POTS associated with CFS. ......Similarly, orthostatic intolerance should not be considered an integral part of MVP. When orthostatic intolerance is a feature of MVP, the condition should be recognized as orthostatic intolerance or POTS associated with MVP."

I guess they mean POTS secondary to CFS or MVP.
