Causes of Essential Tremor

• Essential tremor is the most common type of movement disorder
• Effects men and women equally and is inherited in 60% of all cases
• Tremors on the right side of the body are caused by overactive brain cells in the left thalamus and vice versa.
• Only a small part of the thalamus, called the ventral intermediate nucleus (VIM) is the cause of the tremor.
