(Essential Tremor; Familial Tremor)
- Postural tremor—shaking in certain positions only, such as with arms outstretched
- Kinetic or action tremor—shaking that gets worse during activities, such as eating or shaving
- Tremor that occurs when standing or moving the limbs, but not usually at rest
- Uncontrollable, rhythmic movement
- Shaking most common in hands, arms, head, or voice
- 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
- Shaking that may decrease when using alcohol
- Hearing loss
- Problems with social, functional, or job-related abilities in more severe cases
- Staying well-rested
- Avoiding caffeine
- Avoiding stimulants often found in over-the-counter medications, like cold remedies
- Avoiding temperature extremes
- Anti-seizure medications
- Botulinum injections
- Deep brain stimulation (DBS)—sends painless electrical pulses to the brain, interrupting faulty signals
- Thalamotomy—destroys a tiny part of the brain (less commonly performed than DBS)
