Treatment of dysautonomia in PD, MSA, DLB, etc.

This medical journal article provides a good overview of autonomic dysfunction in Parkinson’s Disease, MSA, and DLB.

The non-motor symptoms addressed include:

* orthostatic hypotension:  If you are dealing with OH, I especially recommend you review Box 1, “Nonpharmacological and pharmacological treatment of orthostatic hypotension.”  I’ve copied the box below as best I can.

* supine hypertension:  This is probably the best overview I’ve seen.

* cardiovascular effects of antiparkinsonian drugs

* dysphagia (swallowing problems)

* gastric motor dysfunction (delayed gastric emptying).  Note that the medication “Domperidone speeds up the emptying of the stomach…”  This medication is not available in the US.

* constipation

* bowel dysfunction

* urinary dysfunction.  I had never seen this data before:  “More than 50% of MSA patients suffer from recurrent infections and a significant number (approximately 25%) die of subsequent complications.”

And this is a useful point as well:  “Missclassification of urogenital autonomic dysfunction as benign prostatic hyperplasia has been reported which may increase the risk of unnecessary urological surgery.”

* sexual dysfunction

* sweating abnormalities

I suggest reading only about the symptoms or disorder of interest to you.

Box 1. Nonpharmacological and pharmacological treatment of orthostatic hypotension.

Nonpharmacological procedures
* Avoid sudden posture changes, particularly after long periods in supine position or during venodilating conditions (i.e. hot baths).
* Increase of daily salt (3-6 g NaCl) and water (2-3 l) intake.
* Diet low in carbohydrates; increase of meal frequency while meal size should be decreased.
* Isotonic exercise such as swimming, aerobic training, bicycling or walking at moderate level.
* Application of counter manoeuvres such as squatting or ‘derby chair’.
* Wearing of elastic stockings or an elastic suit.
* Raised upper body position during sleeping (15-30 cm).

Pharmacological procedures – Increase of blood volume
* Fludrocortisone initial dose of 0.1-0.2mg/d; up to a max of 1mg/d. Caution: cardiac insufficiency, hypocalcaemia, oedema.
* Erythropoietin 4000 IE s.c. twice a week. Caution: iron substitution; increase in haematocrit; hypertension.
* Desmopressin nasal application via pump spray, particularly indicated in nycturia. Caution: hyponatraemia, hypertension.

Pharmacological procedures – Increase of peripheral vasoconstriction
* Midodrine three times 2.5-10mg/d, up to a max 40mg/d; administration not later than 5 pm. Caution: supine hypertension, pruritus.
* Ephedrine three times 12.5-25mg/d. Caution: tachycardia, tremor, supine hypertension.
* Yohimbine two to three times 8mg/d p.o. Caution: diarrhoea, nervousness, panic attacks.
* Caffeine 250mg (=2 cups of coffee) in the morning. Caution: tachyphylaxia.
