Causes. Parkinson’s disease is one of the main causes of essential tremor. The tremors that it induces are constant though. And they become worse whenever a person tries to hold an object because the disease also affects a person’s muscle coordination and ability to move freely. Sometimes, essential tremor happens because a person has certain hormone levels that are too low though. So taking prescription medications that raise the these levels can help. There also seems to be an underlying predisposition for essential tremor since those who have family members with tremors are more likely to develop them.
