What characterizes benign essential tremor?

Benign essential tremor is indeed characterized by a tremor that typically worsens with stress and can improve with alcohol consumption. This condition often presents as an involuntary shaking, primarily of the hands and arms, but can also affect the head and voice. The specific relationship with alcohol is particularly noteworthy; many patients report a temporary reduction in tremor severity after consuming small amounts of alcohol, distinguishing it from other movement disorders.

The tremor in benign essential tremor is usually action-based, meaning it manifests during voluntary movements, which can be exacerbated by emotional stress or fatigue. Understanding this unique response to stress and alcohol helps differentiate benign essential tremor from other neurological conditions that may present with tremor as a symptom.
