Shaking hands, or tremors, can be a symptom of various conditions, with essential tremor being one of the most common causes. Essential tremor is a neurological disorder that results in involuntary and rhythmic shaking. It can affect almost any part of your body, but the trembling occurs most often in your hands, especially when you do simple tasks like drinking a glass of water or tying your shoelaces.

Essential tremor is often confused with Parkinson’s disease, but there are key differences. In Parkinson’s disease, tremors occur mainly at rest, and activity tends to reduce the symptoms. In contrast, essential tremor is an action tremor, meaning that the involuntary shaking increases when you move and try to use your hands.

This condition can also cause head nodding or voice shaking, but it’s less common in Parkinson’s patients. Essential tremor usually affects both sides of the body, but the degree of tremor can vary. It often begins mildly and can progress over time. Cerebellar tremor is another type, where a person may have a postural hand tremor or an intention tremor, as described by Dr. Umeh.

Treatment options for essential tremor include medications and, in more severe cases, surgical interventions like deep brain stimulation. This two-step surgery involves implanting electrodes in the brain and a neurostimulator device under the skin to help control the tremors.

Remember, while essential tremor is a common cause of shaky hands, there are other possible causes too. These can range from benign reasons like excessive caffeine intake to more serious conditions like neurological disorders. It’s crucial to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
