Background: Akathisia is an inner urge to move a body area with an objective motor component of restlessness. Tardive akathisia (TA) is usually bilateral with a predominant lower-body presentation. We report two patients with an asymmetrical predominantly upper-body involvement. Case Report: Two young men with history of psychiatric problems and neuroleptic use revealed atypical TA, characterized by asymmetrical and predominantly upper-body involvement. Their main manifestations were rubbing the face, mostly with one hand, accompanied by an inner sensation of restlessness...

Background: Sleep-related rhythmic movement disorder occurs frequently in childhood with a minority of patients having persistent symptoms in adolescence. Phenomenology Shown: We describe a 14-year-old female showing a typical example of head banging at onset of sleep. Educational Value: Sleep-related rhythmic movement disorder usually has a benign and self-limiting nature and medication might only be warranted in cases of severe sleep disruption or frequent injuries...

Clinical Vignette: A 64-year-old female with essential tremor (ET) presents for evaluation of deep brain stimulation (DBS) candidacy. Examination revealed subtle dystonic features as well as a disabling postural-action tremor. Clinical Dilemma: Can dystonia occur in the setting of the diagnosis of ET and can its presence alter DBS target selection? Clinical Solution: Unilateral DBS implantation of the ventralis intermedius (Vim) led to improvement in both tremor and dystonic posturing...

Background: Hemifacial spasms are involuntary contractions of the muscles of one side of the face. Case Report: Here, we report a 5-year-old female patient with a significant past medical history, including mucopolysaccharidosis type VI, who also presented with hemifacial spasms. Further investigations showed narrowing of skull foramina and hydrocephalus, but no compression of the facial nerve. Carbamazepine was given to the patient, which caused cessation of the spasms...

Background: Cerebrotendinous xanthomatosis is a rare autosomal recessive neurometabolic disorder characterized by chronic diarrhea, tendon xanthomas, juvenile cataracts, and neurological symptoms. Case Report: An adult patient with cerebrotendinous xanthomatosis exhibited ataxia and palatal tremor in the absence of tendon xanthomas and cataracts. Discussion: The importance of this case resides on the fact that cerebrotendinous xanthomatosis should be considered as a possible etiology of the syndrome of progressive ataxia with palatal tremor, even in the absence of tendon xanthomas and cataracts...

Adrian Handforth, Gail A Parker
Background: Increased depression, hearing loss, dementia, alcoholism, and mortality in essential tremor patients remain unexplained. We investigated whether conditions associated with tremor are linked to chronic stress. Methods: The FY2013 Veterans Affairs database was queried for 38 selected dual diagnosis combinations in 5,854,223 veterans aged 21-95 years. Results: Post-traumatic stress disorder, anxiety, and depression were the most common psychiatric diagnoses in tremor patients, with the odds ratio exceeding 2 in all 15-year cohorts...

Zain Guduru, John Morgan, Kapil Sethi
Background: We report a patient who developed lower facial muscle spasm at rest and bilateral facial synkinesis several months after treatment of Guillain-Barré syndrome (GBS); this finding, to our knowledge, is hitherto unreported. Phenomenology Shown: Bilateral synkinesis, facial muscles spasm at rest, bilateral postparalytic facial syndrome. Educational Value: Aberrant regeneration of nerve fibers post GBS, resulting in facial muscles spasm at rest, bilateral synkinesis...

María Ruiz-Julián, Jorge Luís Orozco, Alexandre Gironell
Background: Primary orthostatic tremor (POT) is an infrequent disorder whose physiopathology is unknown. Current medication is largely ineffective or only offers mild benefits. Case Report: A 75-year-old female with refractory POT treated with 4 mg/day of perampanel achieved complete symptom resolution. Owing to adverse effects, the patient reduced intake to 2 mg/day, but even at this lower dose the benefit was maintained. Discussion: We report the complete resolution of POT symptoms using low doses of perampanel, an antiepileptic drug that blocks glutamate-mediated post-synaptic excitation...

Background: In the field of translational neuroscience research, it is critical to utilize a large animal model to test the feasibility, safety, and functionality of novel therapies. Here, we describe a protocol for the development of a large animal model of tremor. Methods: In a pig model, tremor was induced with harmaline and measured with wireless accelerometers attached to the limbs. Three different doses of harmaline were tested and three repetitive injections were made at 72-hour intervals...

#14
David G Coughlin, Tanya M Bardakjian, Meredith Spindler, Andres Deik
Background: Hereditary myoclonus dystonia is often due to changes in the SGCE gene. Dystonia (DYT)- SGCE has a variable phenotype that can involve focal or generalized myoclonus and various forms of task-specific, segmental, or generalized dystonia. Psychiatric comorbidities are common. Case Report: We report a case of a young woman with generalized myoclonus, dystonia, and intellectual disability. She was found to have a novel SGCE splice site variant. Discussion: This novel variant is very likely pathogenic by in silico analysis and has not been previously reported...

Background: The search for essential tremor (ET) genes is active, and it is only a matter of time before genetic tests become available. Genetic testing preferences in families have been studied in numerous other neurological disorders but there are no published data about ET. Methods: We surveyed 34 ET probands and their relatives (43 affected, 28 unaffected) enrolled in our Family Study of Essential Tremor to assess their interest in genetic testing. We examined whether clinical factors influenced their interest in testing...

Background: Impedance is an integral property of neuromodulation devices that determines the current delivered to brain tissue. Long-term variability in therapeutic impedance following deep brain stimulation (DBS) has not been extensively investigated across different brain targets. The aim was to evaluate DBS impedance drift and variability over an extended postoperative period across common DBS targets. Methods: Retrospective data from 1,764 electrode leads were included and drawn from 866 DBS patients enrolled in the University of Florida Institutional Review Board-approved INFORM database and analyzed up to 84 months post implantation...

Background: DYT6 dystonia can have an unpredictable clinical course and the result of deep brain stimulation (DBS) of the internal part of the globus pallidus (GPi) is known to be less robust than in other forms of autosomal dominant dystonia. Patients who had previous stereotactic surgery with insufficient clinical benefit form a particular challenge with very limited other treatment options available. Case Report: A pediatric DYT6 patient unexpectedly deteriorated to status dystonicus 1 year after GPi DBS implantation with good initial clinical response...

REVIEW
Annu Aggarwal, Mohit Bhatt
Background: Wilson disease (WD) is an inherited neurometabolic disorder that results in excessive copper deposition in the liver and the brain, affecting children and young adults. Without treatment the disease is invariably fatal. Though treatments for WD have been available since the 1950s, the disease continues to be associated with considerable morbidity and mortality because of missed diagnosis, and delayed or inadequate treatment. In this paper we survey WD-related literature in order to review recent advances in WD treatment...

Background: Myoclonic jerks are due to sudden, brief, involuntary muscle contractions, positive myoclonus, or brief cessation of ongoing muscular activity, negative myoclonus, and may be difficult to recognize. Case Report: We describe an immunocompetent, adult, male patient with sleep-related, multifocal, myoclonic jerks and neurotoxoplasmosis with abnormal cerebrospinal fluid but normal brain imaging. There was complete resolution of the myoclonus with antitoxoplasmosis therapy after 1 week, and no relapse after 1 year...
