What Is a Familial Tremor?

Family tremor, ^[1] is a genetic-related tremor that can occur in all ages. The total amplitude of tremor increases with muscle tension. It is mainly found in the distal end of the upper limbs, and the lower limbs are rarely affected, but the lips, jaw, and tongue also occur. This tremor should be distinguished from tremors caused by Parkinson's disease and cerebellar disease. It differs from Parkinson's disease in that it is not accompanied by extrapyramidal symptoms such as increased muscle tone and loss of movement; it is different from cerebellar tremor in that the latter has features such as reduced muscle tone and ataxia .
