REVIEW
K Mitra, P K Gangopadhaya, S K Das
Parkinsonism plus syndrome is a group of heterogeneous degenerative neurological disorders, which differ from the classical idiopathic Parkinson's disease in certain associated clinical features, poor response to levodopa, distinctive pathological characteristics and poor prognosis. Associated clinical features include symmetrical onset, infrequent or atypical tremor, prominent rigidity in axial musculature, bradykinesia, early postural instability, supranuclear gaze palsy, early autonomic failure, pyramidal affection, cerebellar involvement, alien limb phenomenon, apraxia and significant early cognitive dysfunction in some cases...

Sleep disorders are commonly seen in atypical parkinsonism, with particular disorders occurring more frequently in specific parkinsonian disorders. Multiple systems atrophy (MSA) is a synucleinopathy often associated with nocturnal stridor which is a serious, but treatable condition highly specific to MSA. In addition, this disorder is strongly associated with rapid eye movement (REM) sleep behavior disorder (RBD), which is also seen in dementia with Lewy bodies (DLB). RBD is far less prevalent in progressive supranuclear palsy (PSP), which is a tauopathy...

BACKGROUND: Hemichorea/hemiballism associated with nonketotic hyperglycemia is a well-recognized syndrome, but few case series have been reported in the literature. CASE REPORT: We describe 20 patients with hemichorea/hemiballism associated with hyperglycemia (9 males and 11 females) with mean age of 67.8 years. Ten patients had a previous diagnosis of type 2 diabetes mellitus, and one had type 1 diabetes mellitus. Six of them had documentation of poor diabetic control over at least the last 3 months...

BACKGROUND/AIMS: The topological organization of brain functional networks is impaired in Parkinson's disease (PD). However, the altered patterns of functional network hubs in different subtypes of PD are not completely understood. METHODS: 3T resting-state functional MRI and voxel-based graph-theory analysis were employed to systematically investigate the intrinsic functional connectivity patterns of whole-brain networks. We enrolled 31 patients with PD (12 tremor dominant [TD] and 19 with postural instability/gait difficulty [PIGD]) and 22 matched healthy controls...

Parkinson's disease (PD) is a relentlessly progressive neurodegenerative disorder associated with hallmark motor and nonmotor symptoms (NMS) such as sleep disturbances and cognitive dysfunction. While dopaminergic treatments have improved the motor aspects of PD, progression remains inevitable. Research has recently increasingly focused on strategies to modify disease progression and on nonmotor manifestations of PD, given their impact on patients' quality of life. Obstructive sleep apnea (OSA) is a treatable sleep disorder, common in the general population, associated with excessive daytime sleepiness and neurocognitive deficits...

This is a retrospective study of all patients presenting to our paediatric unit with status dystonicus (SD) over a period of five years. Anonymous information was collected and a descriptive analysis is made. There were four episodes of SD in three children between 11 and 15 years of age. All children are known to have severe dyskinetic cerebral palsy and presented with an acute or sub-acute deterioration in their symptoms. Symptoms were triggered by infections in three of the four episodes. Early features included frequent and repetitive generalized muscle spasms, poor swallowing, poor sleep, distress and pain...

BACKGROUND: Heterogeneous by the underlying pathobiology and clinical presentation, childhood onset dystonia is most frequently progressive, with related disability and limitations in functions of daily living. Consequently, there is an obvious need for efficient symptomatic therapies. METHODS AND RESULTS: Following lesional surgery to basal ganglia (BG) and thalamus, deep brain stimulation (DBS) is a more conservative and adjustable intervention to and validated for internal segment of the globus pallidus (GPi), highly efficient in treating isolated "primary" dystonia and associated symptoms such as subcortical myoclonus...

Deep brain stimulation (DBS) has become a mainstay of dystonia management in adulthood. Typically targeting electrode placement in the GPi, sustained improvement in dystonic symptoms are anticipated in adults with isolated genetic dystonias. Dystonia in childhood is more commonly a symptomatic condition, with dystonia frequently expressed on the background of a structurally abnormal brain. Outcomes following DBS in this setting are much more variable, the reasons for which have yet to be elucidated. Much of the focus on improving outcomes following DBS in dystonia management has been on the importance of patient selection, with, until recently, little discussion of the choice of target...

Hereditary dopamine transporter deficiency syndrome (DTDS) is a neurotransmitter disorder caused by a defect in the neuronal uptake of dopamine. To date, 20 patients are reported in the literature, and we present 2 additional patients with DTDS harboring novel homozygous SLC6A3 gene mutations. Patient A is an 8-month-old male with neonatal-onset hypotonia, who developed orolingual dyskinetic movements and oculogyric crises after 4 months of age, with evolution to status dystonicus episodes. Patient B is a 4-year-old male who also had hypotonia since birth, with additional severe limb contractions and oculogyric crises after the age of 3 months, with a misdiagnosis of epileptic encephalopathy...

PURPOSE: There is a paucity of effective long-term medication treatment for secondary dystonias. In situations where significantly impairing secondary dystonias fail to respond to typical enteral medications and intrathecal (or even intraventricular) baclofen, consideration should be given to the use of deep brain stimulation (DBS). While Level I evidence and long-term follow-up clearly demonstrate the efficacy of DBS for primary dystonia, the evidence for secondary dystonia remains mixed and unclear...

Christine M Stahl, Steven J Frucht
In this review, we summarize recent advances in understanding the etiology, risk factors and pathophysiology of focal task specific dystonia (FTSD), movement disorders characterized by abnormal motor activation during the performance of specific, repetitive actions. We focus on two common FTSD, musician's dystonia and writer's cramp. FTSD may pose a threat to the patient's livelihood, and improved therapeutic treatments are needed.

BACKGROUND: Hemichorea-hemiballism (HCHB) is a hyperkinetic movement disorder with features of both chorea and ballism occurring on the same side. CASE REPORT: We present a case of HCHB due to nonketotic hyperglycemia (NKH) that was the initial presentation of diabetes and was irreversible clinically even after 6 months of optimal blood sugar control. DISCUSSION: Although HCHB due to hyperglycemia is a potentially reversible condition in the majority of patients, prolonged uncontrolled hyperglycemia may cause ischemic insult and persistent symptoms...
