Ask Mayo Clinic: When should I see a provider about my shaking hands?

Mayo Clinic explains that temblor (shaking) can have many causes, including caffeine, falta de sueño, estrés y otros factores, que pueden provocar un temblor temporal que va y viene. Essential tremor, however, is described as a neurologic movement disorder with rhythmic shaking that typically worsens gradually over the years, often affecting both hands during movement and fine motor tasks. Parkinson’s disease tremor is more likely to occur at rest, such as when an arm is relaxed. Because features can overlap and both conditions can coexist, diagnosis requires careful evaluation, a neurologic exam, and sometimes tests like SPECT. Treatment depends on how much the tremor disrupts daily life.
