Background A 75-year-old woman with rheumatoid arthritis presented with a 4-year history of chorea to a hospital movement disorder clinic. The involuntary movements were initially mild, affecting only the right side of the body, but gradually worsened and became bilateral. There was no relevant family history. Medications included hormone replacement therapy (HRT), diclofenac sodium, vitamin D, folic acid, methotrexate and zopiclone. On examination, bilateral choreiform movements were seen… 
Delayed onset dancing hand syndrome following thalamic hemorrhage
TLDR
A patient of 8 months old left thalamic hemorrhage possibility of post stroke seizure or new-onset lacunar stroke was considered and there was improvement in his involuntary movements and was discharged on day 5 (video 2).
Differential Diagnosis of Chorea
  • R. Walker
  • Medicine
    Current neurology and neuroscience reports
  • 2011
TLDR
Correct diagnosis is essential for appropriate genetic counseling, and ultimately, for future molecular therapies, with many patients remaining undiagnosed.
Apenas mais um acidente de trabalho? Relato de um caso clínico de coreia de Huntington
TLDR
The patient was referred for consultation with a neurologist and Huntington disease was diagnosed as the cause of the chorea, a 41 year-old married Caucasian male living in a nuclear family with no relevant previous medical history.
Chorea disclosing a polycythemia vera
TLDR
The case of a 70 year-old woman whose polycythemia vera (PV), with Janus Kinase-2 (JAK2) mutation, presented as chorea, resolved quickly after hydroxyurea therapy.
SSRI Facilitated Crack Dancing
TLDR
This is the first documented case of an SSRI facilitating the “crack dance” in a 32-year-old male who had been using cocaine for many years and was recently started on paroxetine, a selective serotonin reuptake inhibitor (SSRI) for worsening depression four weeks before presentation.

The causes of sporadic and 'senile' chorea.
TLDR
The majority of patients with 'senile' chorea actually have Huntington's disease even in the absence of a family history, according to a detailed prospective study of patients presenting with undiagnosed chorea over a three year period.
Cause and course in a series of patients with sporadic chorea
TLDR
Although a convincing concordance between choreic signs and neuroradiological findings was possible in 4 patients only, it was possible to assign an aetiology in most cases with vascular related causes the most frequent and metabolic factors often participating.
Chorea and contraceptives: Case report with pet study and review of the literature
TLDR
A positron emission tomography study with 18F‐fluorodeoxyglucose demonstrated a dense focus of increased glucose metabolism involving the body of the left caudate nucleus in a patient with OC‐induced chorea in the absence of systemic lupus erythematosus or antiphospholipids.
Choreic syndrome and coeliac disease: A hitherto unrecognised association
TLDR
Unexpectedly, most of these patients showed a notable improvement in their motor symptoms after the introduction of a gluten‐free diet.
Huntington’s disease and other choreas
TLDR
The symptomatic treatment of chorea is unsatisfactory and, at least in HD, neuropsychiatric disturbance may be much more important for the family, and potential disease-modifying treatments are now being explored in this condition.
Late recurrences of Sydenham’s chorea are not associated with anti-basal ganglia antibodies
TLDR
The likely pathophysiology of late recurrences of Sydenham's chorea is dopamine hypersensitivity of chronically damaged basal ganglia neurones possibly following induction of an autoimmune antibody response in childhood.
Oral contraceptive induced chorea: another condition associated with anti-basal ganglia antibodies
TLDR
A patient developed a chorea triggered by the use of oral contraceptives with no definite evidence of previous Sydenham’s chorea or recent streptoccocal infections, but the patient had positive anti-basal ganglia antibodies, which supports an immunological basis for the pathophysiology of this chorea.
Rheumatoid arthritis with chorea. A case report.
TLDR
The case of a 71-year-old woman with chorea and “definite rheumatoid arthritis” is described and her chorea is compared with other forms of chorea, in particular Sydenham's chorea.
Spectrum of movement disorders in neuroferritinopathy
