Familial Tremors Symptoms & Diagnosis


ET is generally not serious, but its severity may vary and worsen over time. Symptoms may include:

  • Shaking only in certain positions or during activity
  • Trouble with fine motor skills, such as drawing, sewing, or playing an instrument
  • Shaking that gets worse from caffeine, stress, fatigue, or heat
