Chorea-acanthocytosis (ChAc) is the most common subtype of neuroacanthocytosis syndrome, characterized by the presence of acanthocytes and neurological disorders. It is thought to be caused by VPS13A mutations. Characteristic movement disorders in ChAc is choreiform movements affecting both trunk and extremities and prominent orolingual dyskinesia is pathognomonic. Acanthocytosis in peripheral blood smear, elevated serum creatine kinase and atrophy of heads of caudate nuclei and dilation of the anterior horn of the lateral ventricles in magnetic resonance imaging could assist the diagnosis of ChAc...

Introduction: Blepharospasm is characterized by involuntary eyelid spasms. It can be associated with perioral dystonia (Meige's syndrome or orofacial dystonia). We aimed at studying resting-state functional brain connectivity in these patients and its potential modulation by therapeutic botulinum toxin injections. Methods: We performed resting-state functional MRI and a region of interest-based analysis of functional connectivity in 13 patients with blepharospasm/Meige's syndrome in comparison to 13 healthy controls...

The use of botulinum neurotoxin serotype A (BoNT-A) injections for the treatment of orofacial dyskinesia secondary to anti- N -methyl-d-aspartate receptor (NMDAR) encephalitis is rarely reported. Here, we report a case of an urgent, successful management of severe orofacial dyskinesia in an 8-year-old girl with anti-NMDAR encephalitis using BoNT-A injection. The patient presented with de novo unilateral paroxysmal movement disorder progressing to generalized dystonia and repetitive orofacial dyskinesia. Diagnosis was confirmed by the presence of NMDAR antibodies in serum and cerebrospinal fluid...

BACKGROUND: Focal embouchure dystonia impairs orofacial motor control in wind musicians and causes professional disability. A paucity of quantitative measures or rating scales impedes the objective assessment of treatment efficacy. OBJECTIVES: We quantified specific features of focal embouchure dystonia using acoustic measures and developed a metric to assess severity across multiple domains of symptomatic impairment. METHODS: We recruited 9 brass musicians with and 6 without embouchure dystonia...

CONTEXT: Despite being the most common cause of cranial dystonia, Meige's syndrome remains a rare clinical entity. Characterized by blepharospasm and orofacial dystonia, patients suffering from Meige's syndrome benefit from the injection of botulinum toxin (BTX). AIMS: As the majority of the studies tend to discuss Meige's syndrome with blepharospasm patients, there is a paucity of case-based studies dealing exclusively with this syndrome. Hence, we intended to characterize and define the evolution of this syndrome and objectively determine the response of the patients suffering from this entity to BTX therapy...

Brain calcifications may be an incidental finding on neuroimaging in normal, particularly older individuals, but can also indicate numerous hereditary and nonhereditary syndromes, and metabolic, environmental, infectious, autoimmune, mitochondrial, traumatic, or toxic disorders. Bilateral calcifications most commonly affecting the basal ganglia may often be found in idiopathic cases, and a new term, primary familial brain calcification (PFBC), has been proposed that recognizes the genetic causes of the disorder and that calcifications occurred well beyond the basal ganglia...

BACKGROUND: In accordance with German neurosurgical and neurological consensus recommendations, lead placements for deep brain stimulation (DBS) in patients with Parkinson's disease (PD) are usually performed with the patient awake and in "medication off" state. This allows for optimal lead position adjustment according to the clinical response to intraoperative test stimulation. However, exacerbation of Parkinsonian symptoms after withdrawal of dopaminergic medication may endanger the patient by inducing severe "off" state motor phenomena...

Orofacial movement disorders (OMDs) include dystonia, dyskinesia, drug-induced extrapyramidal reactions, and bruxism. The definition, epidemiology, pathophysiology, clinical features, and management are detailed. OMDs are often disabling and affect patients' overall quality of life with pain, difficulty chewing food, speech difficulty, drooling, and social embarrassment. Management involves medications, botulinum toxin injections, and peripheral or central surgery. Botulinum toxin injections are the most effective management, often used in conjunction with medications...

Despite numerous case reports, the evidence for treatment of bruxism is still low. Different treatment modalities (behavioral techniques, intraoral devices, medications, and contingent electrical stimulation) have been applied. A clinical evaluation is needed to differentiate between awake bruxism and sleep bruxism and rule out any medical disorder or medication that could be behind its appearance (secondary bruxism). A polysomnography is required only in a few cases of sleep bruxism, mostly when sleep comorbidities are present...

Frontotemporal dementia (FTD) refers to a group of clinically and genetically heterogeneous neurodegenerative disorders that are a common cause of adult-onset behavioural and cognitive impairment. FTD often presents in combination with various hyperkinetic or hypokinetic movement disorders, and evidence suggests that various genetic mutations underlie these different presentations. Here, we review the known syndromatic-genetic correlations in FTD. Although no direct genotype-phenotype correlations have been identified, mutations in multiple genes have been associated with various presentations...

Non-Wilsonian hepatolenticular degeneration (NWHD) is a heterogeneous neurological disorder occurring secondary to chronic acquired liver disease. Genetically determined familial NWHD is rare, poorly understood, and often mistaken for Wilson's disease (WD). We analysed clinical and MRI profiles of NWHD patients who did not have obvious cause for acquired liver disease, such as alcohol intake or hepatitis. Six patients from four families (four males, two females, mean age: 17.0±standard deviation 7.9years), presenting with chronic extrapyramidal disorder resembling WD and imaging (abdominal ultrasound/MRI) evidence of cirrhosis were studied...

This series of columns has 2 main goals: (1) to explain the use of class warnings by the US Food and Drug Administration and (2) to increase clinicians' awareness of movement disorders that may occur in patients being treated with antipsychotic medications and why it is appropriate and good practice to refrain from immediately assuming the diagnosis is tardive dyskinesia/dystonia (TD). This first column in the series will focus on the second goal, which will then serve as a case example for the first goal. Clinicians should refrain from jumping to a diagnosis of TD because a host of other causes need to be ruled out first before inferring iatrogenic causation...

A deficiency of GTP cyclohydrolase, encoded by the GCH1 gene, results in two neurological diseases: hyperphenylalaninaemia type HPABH4B and DOPA-responsive dystonia. Genes involved in neurotransmitter metabolism and motor systems may contribute to palatogenesis. The purpose of the study was to analyse polymorphic variants of the GCH1 gene as risk factors for non-syndromic cleft lip with or without cleft palate (NSCL/P). Genotyping of nine polymorphisms was conducted in a group of 281 NSCL/P patients and 574 controls...
