What are the various causes of tremors beyond Parkinson's disease, and how do these conditions influence the frequency and severity of tremor symptoms?

One cause is neuronal irritability which is affected by low blood sugars (hypoglycemia). You have a counter-neurotransmitter that then comes in to raise the blood sugars and this is epinephrine (adrenaline).

Other symptoms are the following:

1. Anxiety

2. Sweating

3. Tremors

4. High pulse rate

5. Weakness

6. Mental confusion

7. Headaches

8. Depression or lethargy
