A neurological disorder characterized by shaking. Benign familial tremors tend to run in families and are usually harmless. Although they can develop at any age, these tremors become more common as people age. They may manifest themselves as head nodding, difficulty holding small objects, trembling hands, or a quivering voice.
A neurological disorder characterized by shaking. Benign familial tremors tend to run in families and are usually harmless. Although they can develop at any age, these tremors are more common in older people. They may manifest themselves as head nodding, difficulty holding small objects, or a quivering voice. Over time other parts of the upper body (such as the eyelids or arms) may be affected, but the lower body is usually not involved. Benign familial tremors generally worsen during periods of activity, purposeful movement, or emotional stress. Diagnosis is made on the basis of physical examination and personal and family medical history. Sometimes tests such as CT (computed tomography) scanning and MRI (magnetic resonance imaging) are ordered to rule out other causes of tremors. Treatment is often not necessary. Although they affect movement or speech, benign familial tremors seldom cause any other problems. However, if tremors are severe and interfere with one’s ability to perform daily activities, the doctor can order medications such as anticonvulsants, beta blockers, or tranquilizers. It is also helpful to avoid caffeine and other stimulants.
