title: Upper limb tremor.
abstract: Tremor is a common clinical problem in middle-aged and older patients, and Parkinson disease (PD) is one of the commonest causes. Careful history-taking and physical examination is usually sufficient for diagnosis of PD; extensive investigation is generally not required. Treatment of PD should be individualised, taking into account the patient's age, lifestyle, severity of motor symptoms, level of disability, comorbidities, expectations of treatment and PD subtype (eg, akinetic rigid or tremor dominant). In PD, optimal medical therapy often involves a combination of dopaminergic medications, aiming for doses that provide adequate symptom relief without adverse effects such as dyskinesias and impulse-control disorders. Continuous dopaminergic stimulation and deep brain stimulation should be considered for patients with PD whose motor symptoms cannot be adequately controlled with oral medication, especially those aged less than 70 years.
