{"doi":"10.1002/mdc3.13659","title":"What Is Hemidystonia?","abstract":"Background: Hemidystonia is defined as dystonia restricted to one side of the body. It is traditionally believed to result from a lesion in the contralateral hemisphere. Objectives: To describe a series of hemidystonia patients without lesions on brain imaging. Methods: We searched for individuals with potential hemidystonia who were included in the Dystonia Coalition or Movement Disorder Society Genetic mutation database (MDSgene), and conducted a systematic review. Results: We found 10 individuals classified as hemidystonia or with homolateral limb dystonia among 3696 cases enrolled by the Dystonia Coalition, 9 cases in MDSgene, and one idiopathic case in the literature. None had evidence of a brain lesion. Body distributions used to define hemidystonia varied considerably and were not always restricted to one side of the body. Conclusions: Hemidystonia may be idiopathic or genetic, without any obvious brain lesion. The varied use of the term suggests the need for more specific clinical criteria to define \"half the body.\"","journal":"Movement Disorders Clinical Practice","year":2023,"id":372183,"datarank":0.3583646436026377,"base_score":1.791759469228055,"endowment":1.791759469228055,"self_citation_contribution":0.26876392038420827,"citation_network_contribution":0.08960072321842942,"self_endowment_contribution":0.26876392038420827,"citer_contribution":0.08960072321842942,"corpus_percentile":50.49121992728398,"corpus_rank":6401,"citation_count":5,"citer_count":4,"citers_with_citation_signal":2,"citers_with_endowment":2,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":0.5935,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":350763,"name":"Hyder A.
