Isolated Vocal Tremor as a Focal Phenotype of Essential Tremor: a Retrospective Case Review

Journal of Clinical Movement Disorders – Essential tremor (ET) is a common condition associated with significant physical and psychosocial disability. “Classic” ET is a clinical syndrome of action tremor in the upper limbs and less commonly the head, jaw, voice, trunk, or lower limbs. Current diagnostic criteria for ET exclude isolated vocal tremor (IVT). Failure to recognize IVT as a form of ET may contribute to misdiagnosis and missed opportunities for treatment.
