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
