Journal Detail Information

We present a case of 32-year-old male with profound mental retardation and autism spectrum disorder who had presented with seizures, rigidity and elevated creatine kinase and was initially diagnosed as neuroleptic malignant syndrome (NMS). The patient subsequently had a complicated clinical course, developing refractory status epilepticus, which lead to the eventual diagnosis of progressive encephalomyelitis with rigidity and myoclonus (PERM). We discuss the clinical similarities and differences between NMS and PERM, and highlight the need to consider alternative diagnoses when the clinical picture of NMS is atypical, particularly in this patient group where the history and clinical examination may be challenging.

Paroxysmal Kinesigenic Dyskinesia as the Presenting and Only Manifestation of Multiple Sclerosis after Eighteen Months of Follow-Up.

Marius BAGUMA ; Michel OSSEMANN

Journal of Movement Disorders.2017;10(2):96-98. doi:10.14802/jmd.16055

Other than tremor, movement disorders are uncommon in multiple sclerosis. Among these uncommon clinical manifestations, paroxysmal kinesigenic dyskinesia is the most frequently reported. It is characterized by episodic attacks of involuntary movements that are induced by repetitive or sudden movements, startling noise or hyperventilation. The diagnosis is essentially clinical and based on a good observation of the attacks. It is very easy to misdiagnose it. We describe the case of a young female patient who presented paroxysmal kinesigenic dyskinesia as the first and only clinical manifestation of multiple sclerosis, with no recurrence of attacks nor any other neurologic symptom after eighteen months of follow-up.

Journal of Movement Disorders.2016;9(1):44-49. doi:10.14802/jmd.15035

OBJECTIVE: To evaluate changes in the strength and mechanical properties of neck muscles and disability in patients with cervical dystonia (CD) during a 12-week period following botulinum neurotoxin (BoNT) injections. METHODS: Eight patients with CD volunteered for this prospective clinical cohort study. Patients had received BoNT injections regularly in neck muscles at three-month intervals for several years. Maximal isometric neck strength was measured by a dynamometer, and the mechanical properties of the splenius capitis were evaluated using two myotonometers. Clinical assessment was performed using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) before and at 2, 4, 8, and 12 weeks after the BoNT injections. RESULTS: Mean maximal isometric neck strength at two weeks after the BoNT injections decreased by 28% in extension, 25% in rotation of the affected side and 17% in flexion. At four weeks, muscle stiffness of the affected side decreased by 17% and tension decreased by 6%. At eight weeks, the muscle elasticity on the affected side increased by 12%. At two weeks after the BoNT injections, the TWSTRS-severity and TWSTRS-total scores decreased by 4.3 and 6.4, respectively. The strength, muscle mechanical properties and TWSTRS scores returned to baseline values at 12 weeks. CONCLUSIONS: Although maximal neck strength and muscle tone decreased after BoNT injections, the disability improved. The changes observed after BoNT injections were temporary and returned to pre-injection levels within twelve weeks. Despite having a possible negative effect on function and decreasing neck strength, the BoNT injections improved the patients reported disability.

Journal of Movement Disorders.2016;9(1):40-43. doi:10.14802/jmd.15030

OBJECTIVE: Galvanic vestibular stimulation (GVS) activates the vestibular afferents, and these changes in vestibular input exert a strong influence on the subject's posture or standing balance. In patients with Parkinson's disease (PD), vestibular dysfunction might contribute to postural instability and gait disorders. METHODS: Current intensity was increased to 0.7 mA, and the current was applied to the patients for 20 minutes. To perform a sham stimulation, the current intensity was increased as described and then decreased to 0 mA over the course of 10 seconds. The patient's status was recorded continuously for 20 minutes with the patient in the supine position. RESULTS: Three out of 5 patients diagnosed with PD with postural instability and/or abnormal axial posture showed a reduction in postural instability after GVS. The score for item 12 of the revised Unified Parkinson's Disease Rating Scale part 3 was decreased in these patients. CONCLUSIONS: The mechanism of postural instability is complex and not completely understood. In 2 out of the 5 patients, postural instability was not changed in response to GVS. Nonetheless, the GVS-induced change in postural instability for 3 patients in our study suggests that GVS might be a therapeutic option for postural instability.

N30 Somatosensory Evoked Potential Is Negatively Correlated with Motor Function in Parkinson's Disease.

Suk Yun KANG ; Hyeo Il MA

Journal of Movement Disorders.2016;9(1):35-39. doi:10.14802/jmd.15038

OBJECTIVE: The aim of this study was to investigate frontal N30 status in Parkinson's disease (PD) and to examine the correlation between the amplitude of frontal N30 and the severity of motor deficits. METHODS: The frontal N30 was compared between 17 PD patients and 18 healthy volunteers. Correlations between the amplitude of frontal N30 and the Unified Parkinson's Disease Rating Scale (UPDRS) motor score of the more severely affected side was examined. RESULTS: The mean latency of the N30 was not significantly different between patients and healthy volunteers (p = 0.981), but the mean amplitude was lower in PD patients (p < 0.025). There was a significant negative correlation between the amplitude of N30 and the UPDRS motor score (r = -0.715, p = 0.013). CONCLUSIONS: The frontal N30 status indicates the motor severity of PD. It can be a useful biomarker reflecting dopaminergic deficits and an objective measurement for monitoring the clinical severity of PD.

OBJECTIVE: Parkinsonism and other movement disorders have previously been reported in the acquired hepatocerebral degeneration associated with portosystemic shunting. However, there is no study to date about their prevalence as has been noted in general practice. METHODS: One hundred and forty-three patients with hepatic cirrhosis from the gastroenterology clinic and internal medicine wards were enrolled. Liver data included the diagnoses, etiologies, assessments of complications, and treatments for cirrhosis. Hepatic encephalopathy was classified with regard to the West Haven criteria for semi-quantitative grading for mental status. Neurological examination results and abnormal involuntary movements were recorded as primary outcomes. Neuro-radiology was used for the detection of severe brain lesions. RESULTS: Alcoholism was the most common cause of liver cirrhosis. Eighty-three patients (58%) presented with movement disorders. Asterixis was found in one of the cases. The most common movement disorder seen was an intentional tremor at 37.1%, which was followed by bradykinesia, Parkinsonism, and postural tremors at 29.4%, 10.5%, and 6.3%, respectively. The prevalence of movement disorders simultaneously increased with a high Child-Turcotte-Pugh score. The hepatic encephalopathy was grade 1 and 2. With the inclusion of age-range adjustments, we found that alcoholic cirrhosis and hepatic encephalopathy are statistically significant factors [p < 0.05, odds ratio (OR) = 6.41, 95% confidence interval (CI) 1.38-29.71 and p < 0.001, OR = 13.65, 95% CI 4.71-39.54] for the development of movement disorders in non-Wilsonian cirrhotic patients. CONCLUSIONS: Intentional tremor is a common abnormal movement. Alcoholic cirrhosis and hepatic encephalopathy are significant risk factors in the development of movement disorders in non-Wilsonian cirrhotic patients.
