Is the decrease in dopamine due to Parkinson's a cause of loss of feelings?

Parkinson feeling. Parkinson's disease causes a loss of facial expressivity, so they may look like they have no feelings. This is inaccurate. The underlying loss of Dopamine in certain nerve cells does not cause a loss of feeling. However there may be problems with feelings depending on the person's pre-parkinson emotional makeup. Parkinson's may include depression, mood swings, and hallucinations.

What causes the loss of dopamine in your brain that eventually leads to Parkinson's disease?

Don't really know. The cause of Parkinson's disease is not fully clear, but we do see cases after repetitive head trauma, secondary to multiple strokes, after exposure to carbon monoxide and manganese, and rarely carbon disulfide. Read more...

Can you tell me in Parkinson's disease, does dopamine loss occur merely in the striatum or does it occur in the s.niagra too?

Pigmented nuclei. The dopamine loss involves predominantly the basal ganglia area, but also involves dorsal vagal nucleus, substantial nigra, and areas of any dopamine interaction within brain and brain stem. But, to be complete, Parkinson's is a multi-neurotransmitter degenerative deficiency syndrome with other neurotransmitter systems involved. Read more...

Can low dopamine levels cause cardiac dysfunction? Thanks. I have read that low dopamine levels are related to parkinsons--one of the symptoms being autonomic dysfunction. Could this include cardiac problems--racing, pounding, palpitations?

I . I am not aware of low Dopamine levels directly causing cardiac problems. As far as autonomic dysfunction in regards to the cardiovascular system goes, there is a direct relationship, that being orthostatic hypotension. The symptoms of orthostatic hypotension include lightheadedness, palpitations, weakness, and tremors when attempting to stand up. Some people may also experience visual problems, pounding headaches, fatigue and inability to concentration. Some patients even report fainting when attempting to stand. This topic is definitely worth investigating further. Maybe there is research going on looking at Dopamine in relation to cardiac function. That would be interesting. Take care. Read more...
Unlikely. Low dopamine levels in Parkinson's Disease are specifically related to loss of dopamine producing neurons in the Basal Ganglia of the brain and does not show up on regular blood testing. An isolated low dopamine on blood tests is not in itself is usually meaningless as it is a precursor to epinephrine. It is usually measured to look for high levels of adrenal hormones.
