OBJECTIVES: To describe the phenomenology and prevalence of leg stereotypy syndrome (LSS), characterised chiefly by repetitive, rhythmical, stereotypic leg movement, especially when sitting. METHODS: We sought to characterise LSS in two groups of subjects: (1) general population (GP) group, defined as individuals accompanying patients during their visits to Baylor College of Medicine Parkinson's Disease Center and Movement Disorders Clinic who are not genetically related to the patients; and (2) movement disorders (MD) group, composed of consecutive patients with diagnoses of restless legs syndrome, Parkinson's disease, Tourette syndrome and tardive dyskinesia...

Lingual hematoma is a severe situation, which is rare and endangers the airway. It can develop due to trauma, vascular abnormalities, and coagulopathy. Due to its sudden development, it can be clinically confused with angioedema. In patients who applied to the doctor with complaints of a swollen tongue, lingual hematoma can be confused with angioedema, in particular, at the beginning if the symptoms occurred after drug use. It should especially be considered that dystonia in the jaw can present as drug-induced hyperkinetic movement disorder...

Sydenham's chorea (SC) is an immune-mediated hyperkinetic movement disorder, developing after group A Beta-hemolytic streptococcal (GABHS) infection. Aside from conventional symptomatic treatment (carbamazepine, valproate, neuroleptics), the use of steroids has also been advocated, mainly in severe, drug-resistant cases or if clinically disabling side effects develop with first line therapies. Based on the description of 5 cases followed in the Child Neurology Unit of Santa Maria Nuova Hospital in Reggio Emilia and on the available medical literature on this topic, we propose considering the use of corticosteroids therapy in children with SC, with the administration of IV methyl-prednisolone followed by oral deflazacort in severe cases and of oral deflazacort alone in mild and moderate degrees of involvement...

Tourette syndrome (TS) is a neuropsychiatric disorder with the onset in childhood. TS is a form of tic disorders, and characterized by the motor and vocal tics, and comorbidities such as attention deficit hyperkinetic and obsessive compulsive disorders. These symptoms appear age dependently, showing a wax and wane course, and subside or abolish by the late teens. Pathophysiology of TS involves the dysfunction of both motor and non-motor basal ganglia-thalamo-cortical circuitries. The nigrostriatal dopamine (DA) system takes the exponential decrement at the striatum...

The behavior patterns of hyperactivity, impulsivity and inattention that would ultimately become recognized as Attention-Deficit Hyperactivity Disorder (ADHD) have been described for centuries. Nevertheless, in the past 35 years, advances in diagnostic methods, identification of biomarkers, and treatments have advanced at an exponential rate. ADHD is now recognized as the most common behavioral disorder of childhood, with risks extending well into adulthood for both males and females, leading to its identification as a significant public health issue...

Purpose of review: To discuss selected peer-reviewed research articles published between 2014 and 2016 and highlight 5 clinically relevant messages related to hyperkinetic and hypokinetic movement disorders in patients with chronic psychosis. Recent findings: A recent population-based study complemented data from clinical trials in showing increased risk of developing extrapyramidal symptoms with antipsychotic use. A community service-based longitudinal study showed that dopamine transporter imaging could help identify subgroups of patients with parkinsonism associated with antipsychotics with a progressive course, potentially manageable with l-dopa...

The rate and oscillatory hypotheses are the two main current frameworks of basal ganglia pathophysiology. Both hypotheses have emerged from research on movement disorders sharing similar conceptualizations. These pathological conditions are classified either as hypokinetic or hyperkinetic, and the electrophysiological hallmarks of basal ganglia dysfunction are categorized as prokinetic or antikinetic. Although nonmotor symptoms, including neurobehavioral symptoms, are a key manifestation of basal ganglia dysfunction, they are uncommonly accounted for in these models...

REVIEW
Marta Ruiz-Lopez, Alfonso Fasano
Status dystonicus is a movement disorder emergency that has been a source of controversy in terms of terminology, phenomenology, and management since it was first described in 1982. Here we argue that the current use of the term status dystonicus falls well short of the precision needed for either clinical or academic use. We performed a critical review on this topic, describing possible pathophysiological mechanisms and areas of uncertainties. This review also addresses the problems derived by the extreme clinical heterogeneity of this condition, as the lack of an objective criterion useful for the definition, or the fact that status dystonicus may present not only in the context of a known dystonic syndrome...

The differential diagnosis of fever-induced movement disorders in childhood is broad. Whole exome sequencing has yielded new insights into those cases with a suspected genetic basis. We report the case of an 8-year-old boy with a history of neonatal seizures who presented with near-continuous hyperkinetic movements of his limbs during a febrile illness. Initial diagnostic testing did not explain his abnormalities; however, given the suspicion for a channelopathy, whole exome sequencing was performed and it demonstrated a de novo pathogenic heterozygous variant in KCNQ2...

Pain is an important nonmotor symptom in movement disorders. Dystonia is a hyperkinetic movement disorder characterized by involuntary, sustained or intermittent muscle contractions causing abnormal movements, postures or both. Contrary to common views the nonmotor symptoms are present in dystonia patients. Pain is a prevailing feature of cervical dystonia (CD), the most common form of focal dystonia. The mechanism of pain in CD remains mostly unknown, but there are growing evidence that it could not be only the consequence of muscle hyperactivity...

Dystonia is a hyperkinetic movement disorder, characterized by sustained or intermittent muscle contractions causing abnormal, often repetitive, movements, postures, or both. Executive dysfunction is a feature of cognitive function in idiopathic and DYT1 dystonia. Psychiatric morbidity is increased in dystonia, and depression, anxiety, obsessive compulsive disorders are the most common disorders. Sleep problems and pain are also frequently experienced. Evidence suggest that mood and anxiety disorders are intrinsic to the neurobiology of dystonia, but also that psychiatric co-morbidity can be secondary to pain experience and the psychosocial functioning and quality of life of the patients...

BACKGROUND: Tubulin mutations are a cause of neuronal migrational disorders referred to as tubulinopathies. Mutations in tubulin genes can have a severe impact on microtubule function and result in heterogeneous clinical presentations. Current understanding of the clinical spectrum of tubulinopathies is predominantly based on research in fetal tissue and early-childhood cases. METHODS: Testing of candidate genes followed by whole-exome sequencing was performed in an adult woman with a neurodevelopmental, hyperkinetic movement disorder, to identify the underlying genetic cause...

INTRODUCTION: Alcohol use is a widely prevalent problem and poses hazard during work for certain groups such as fishermen. Disorders such as Attention-Deficit/Hyperkinetic Disorder (ADHD) correlate with early onset and greater severity of alcohol use disorders. AIMS: We planned to study the frequency of ADHD among fishermen in a fishing hamlet of southern India using adult ADHD self-reported scale (ASRS) and correlated with the severity of alcohol use disorder as evidenced by age at initiation of alcohol use, presence of harmful use, or dependence use as defined by Alcohol Use Disorders Identification Test (AUDIT)...

The therapeutic applications of botulinum toxin (BoNT) have grown manifold since its initial approval in 1989 by the US Food and Drug Administration (FDA) for the treatment of strabismus, blepharospasm, and other facial spasms. Although it is the most potent biologic toxin known to man, long-term studies have established its safety in the treatment of a variety of neurologic and non-neurologic disorders. This review focuses on some novel and uncommon uses of BoNT in the treatment of movement disorders, such as oromandibular dystonia, including bruxism, anterocollis, camptocormia, tremor, tics, tardive and levodopa-induced dyskinesia, and restless legs syndrome...
