What are shaky hands?
Shaky hands are a common symptom that can even occur in healthy people. Although there are many causes of shaky hands, in some people there is no known cause. The most common cause is an essential tremor, which often is inherited and considered benign. Shaky hands may occur with conditions that affect only the hands or with conditions that affect the other parts of the body, such as generalized diseases of the neuromuscular system or central nervous system. Diseases that commonly cause shaky hands include Parkinson’s disease, overactive thyroid (hyperthyroidism), and multiple sclerosis.
