Tremor-Dominant Parkinson’s Disease
Tremor-dominant Parkinson’s disease (PD) refers to patients who present initially with tremor with relatively mild bradykinesia and rigidity and who progress slowly over many years with tremor remaining the most prominent clinical symptom together with relatively mild bradykinesia, rigidity, and absence of postural instability. Several reports have subtyped patients with PD in order to compare their projected course over time. In PD, the disease process continues throughout life in a nonlinear fashion without spontaneous or treatment-induced remission. Although different subtyping schemes have been proposed, the most well-defined groups to emerge have been the tremor dominant, akinetic-rigid, and postural instability-gait disturbance (PIGD) subtypes.
