PD subgroups and subtypes : Early Weight Loss


In PwP, weight loss, weight gain, and no significant change in weight

represent a subgrouping. For a year or so before my dx as having PD

(late 2011), I was losing

weight, despite eating well. I lost 40% of my weight. Occasionally,

an acquaintance would ask if I was OK, did I have cancer? (I did

not.) In 2013, a study provided insight and prompted me into

reading locus coeruleus studies.

"CONCLUSIONS: In PD degeneration of noradrenergic neurons, in

particular of the LC, may be required to observe side effects

unrelated to motor symptoms such as body weight deregulation. Our

results support the notion that the LC may be important in

maintaining the activity of the nigrostriatal dopamine pathways, and

thus play a crucial role in weight variation in a PD."

Parkinson's Disease.


Since then, several studies have described weight-loss subtypes in

suspect this could indicate worse form of disease.

Neuronal loss is greater in the locus coeruleus than nucleus basalis

and substantia nigra in Alzheimer and Parkinson diseases.

Did you put any weight back on when you started taking meds? (If you do).

My weight has remained low. Pd meds haven't changed that. C/,L 25/100, amantadine, ropinerole, Mucuna. I eat well and don't skimp. Three squares each day, plus snacks. Days are regimented, meals, meds on schedule.
