Sway patterns in a case of orthostatic tremor responsive to alcohol. These slower orthostatic tremors are frequently associated with other neurologic signs and have a slower tremor frequency than 13 Hz. Tremor during standing usually has a low frequency (range, 4-6 Hz), similar to PD rest tremor frequency, and is improved by levodopa. Pseudo-orthostatic tremor in idiopathic Parkinson’s disease: could it be re-emergent tremor? These observations support the hypothesis that mtDNA dysfunction is engaged in the pathogenesis of idiopathic Parkinson's disease. The tremor lessens partially or completely when the person is walking or sitting. Although the essential clinical features of orthostatic tremor are well established, little is known about the natural progression of the disorder. Here we report two novel mutations in POLG1 in a compound heterozygous patient with autosomal recessive PEO, followed by pseudo-orthostatic tremor evolving into levodopa-responsive parkinsonism.
