Overview

Common causes of tremor include caffeine intake in excess, essential tremor, stress, anxiety, low blood glucose, excessive alcohol, muscle fatigue, aging, Parkinson's disease , hyperthyroidism.

Causes

Common Causes

• Common causes of tremor in primary care setting are :
• Enhanced physiologic tremor
• Essential tremor
• Parkinson’s disease
• include excessive caffeine
• Psychogenic due to stress,anxiety, and depression
• Hypoglycemia
• Fatigue
• aging

Less Common Causes

• Wilson's disease
• Multiple sclerosis
• Alcoholism
• Hyperthyroidism

Common Cause of Tremor	Type of Tremor	Main Feature of Disease
Essential tremor	Action - Postural Tremor	Weakness, hyporeflexia, lack of normal muscle tone
Parkinson’s disease	Resting Tremor	Slow movement, stooped posture, difficulty walking, rigidity imbalance, depression, apathy
Wilson's disease	Unilateral upper motor neuron	Weakness, reduced range of motion, decreased fine motor control of tongue & lips
Multiple sclerosis	Cerebellum	Poorly coordinated movements of speech mechanism, scanning/drunken speech
Hypoglycemia	Basal ganglia	Quick involuntary movements (hyperkinesis)
Alcoholism	Action - Postural Tremor	Less movement (hypokinesis), increased muscle tone
Hyperthyroidism	Action - Postural Tremor	Mixed presentation
