Hand tremors are a slight to significant shaking of the hands, which can occur for many different reasons. These reasons can be completely benign and the shaking can be so minor or only associated with certain activities, that it is rarely bothersome. Some people suffer from more significant hand tremors that are caused by serious conditions. It is always wise to determine the medical cause of hand tremors to rule out potential underlying problems.
One of the most common causes of hand tremors is essential tremor, which most presents in people who are older than 65. Many people automatically assume a person with a tremor that is especially noticed in between activities or when starting an activity, has Parkinson’s disease. This is not always true, and essential tremor is quite different than conditions like Parkinson’s. Though it may be linked to cerebellum activity in the brain, which may not adequately coordinate muscle movement, it not always a serious condition, or one that necessarily requires treatment. Even though studies indicate involvement of the cerebellum, this may be a normal human variation instead of indicating brain damage.
Sometimes more than one person from a family has an essential tremor, and though these are most common in older adults, they can occur in younger people too. The part of body affected isn’t always the hands, and some people might have a slight trembling in their voices or show tremors in other parts of the body. When several people from the same family have essential tremor like hand tremors, it’s usually called familial tremor.
There are other things than can cause hand tremors or tremors in other parts of the body. Conditions like Parkinson’s disease can result in it, some medications create tremor, and alcohol withdrawal may cause it to a great degree. People who are tired or stressed out could develop hand tremors, and they may be common in people who drink too much caffeine or who have conditions like anxiety and panic disorder.
Most people who experience a tremor from something like drinking too much coffee will notice it abates in a short while. When hand tremors don’t go away, a person should get medical attention. Doctors will likely want to know the history of when tremors started, when they’re most common, and whether anyone else in the family has them. They can perform numerous tests to determine cause, or at least to rule out very serious causes.
Some people have tremors that are very severe and they do require treatment. Treatment could include various medications to reduce tremors. Sometimes people have surgical procedures like deep brain stimulation, but this would generally not be an option for those with very minor and occasional shaking of the hands.
