Orthostatic tremor is a rare tremor syndrome triggered exclusively by standing, with pathognomonic neurophysiological features. More recently, it has been suggested that orthostatic tremor can present either in isolation (pure orthostatic tremor) or associated with other movement disorders (orthostatic tremor-plus). The present study aims at expanding the knowledge concerning orthostatic tremor associated with other movement disorders. ⋯ One of the largest series on orthostatic tremor is presented and the second only focused on additional movement disorders. A progressive course was found, with increasing disability associated with orthostatic tremor. Dementia with Lewy bodies and task specific arm dystonia are reported for the first time as associated movement disorders.

Case ReportsHeadache in three new cases of Harlequin syndrome with accompanying pharmacological comparison with migraine.
Harlequin syndrome (HS) is a rare autonomic disorder characterised by unilateral diminished sweating and flushing of the face in response to heat or exercise. Some patients with HS complain of headache. ⋯ These data do not show any correlation between the phenotypic expression of migraine and HS suggesting the syndromes are pathogenetically independent.

Randomized Controlled Trial Multicenter StudyImpact of DaTscan SPECT imaging on clinical management, diagnosis, confidence of diagnosis, quality of life, health resource use and safety in patients with clinically uncertain parkinsonian syndromes: a prospective 1-year follow-up of an open-label controlled study.
This study assessed the impact of DaTscan on clinical management, diagnosis, confidence of diagnosis (CoD), quality of life (QoL), health resource use (HRU) and safety during a 1-year follow-up in patients with clinically uncertain parkinsonian syndromes (CUPS). ⋯ DaTscan had a significant impact on clinical management, diagnosis and CoD in patients with CUPS. DaTscan is safe and well tolerated, and is a useful adjunct to differentiate a diagnosis of CUPS. Trial registration number http://ClinicalTrials.gov Identifier: NCT00382967.
