Tremors are involuntary, rhythmic muscle movements that cause shaking in one or more parts of the body. They can affect the hands, arms, head, legs, voice, or torso and may be temporary or chronic.
🔹 Genetic (runs in families)
🔹 Affects hands, head, or voice
🔹 Worsens with movement (e.g., holding objects, writing)
🔹 Improves with alcohol in some cases
🔹 Seen in Parkinson’s disease
🔹 Occurs at rest (resting tremor)
🔹 Starts in one hand, spreads slowly
🔹 “Pill-rolling” motion of fingers
🔹 Caused by brain damage or disease (stroke, MS, alcohol damage)
🔹 Occurs at the end of a movement (e.g., reaching for an object)
🔹 Uncoordinated, jerky movements
🔹 Temporary and subtle
🔹 Triggered by stress, caffeine, anxiety, fatigue, or medications
🔹 Often resolves on its own
🔹 Seen in people with dystonia (muscle contractions)
🔹 Irregular movements that improve with rest
🔹 Affects neck, face, hands, or arms
🔹 Rapid shaking in the legs when standing
🔹 Stops when sitting or walking
Neurological disorders (Parkinson’s, multiple sclerosis, stroke)
Genetic (hereditary essential tremor)
Overactive thyroid (hyperthyroidism)
Anxiety, stress, or fatigue
Excess caffeine or alcohol withdrawal
Low blood sugar (hypoglycemia)
Medications (antidepressants, asthma drugs, steroids)
Brain injuries or tumors
🔹 Neurological exam – Tests coordination, strength, reflexes.
🔹 Blood tests – To check thyroid, blood sugar, and toxin exposure.
🔹 MRI/CT scan – To rule out brain disorders.
🔹 Dopamine tests – If Parkinson’s is suspected.
Beta-blockers – Propranolol (for essential tremor).
Anti-seizure drugs – Primidone, gabapentin.
Parkinson’s medications – Levodopa, dopamine agonists.
Anti-anxiety meds – Clonazepam, diazepam (if stress-related).
Reduce caffeine & alcohol intake
Practice relaxation techniques (yoga, meditation)
Improve sleep quality
Use weighted utensils for eating/writing
Weighted pens & adaptive devices to assist daily tasks.
🧠 Deep Brain Stimulation (DBS) – A brain implant that reduces tremors.
🩺 Focused Ultrasound Therapy – Uses sound waves to target tremor-causing areas.
🔹 If tremors worsen over time or interfere with daily life.
🔹 If tremors occur at rest (may indicate Parkinson’s).
🔹 If accompanied by balance issues, weakness, or speech changes.
