What Can Cause Hand Tremors?

Parkinson's Disease

Parkinson's disease is a progressive condition that impairs movement. The condition often starts with a barely noticeable tremor in one hand that occurs at rest. As the disease worsens, patients may also experience stiffness and slowing of movements, and writing and speech may be altered. Doctors diagnose Parkinson's disease with neurological examinations and imaging studies, and patients may need to have repeated examinations to confirm the diagnosis. Treatments for Parkinson's disease include medications such as carbidopa-levodopa and dopamine agonists. These medications can help reduce tremors and make it easier for patients to move and write. If medication is ineffective, doctors may consider a surgical procedure known as deep brain stimulation. This procedure may temporarily halt tremors and other involuntary movements, and it also reduces muscle rigidity.
