X-Linked Parkinsonism: Phenotypic and Genetic Heterogeneity.

Mov Disord 2021 May 7. Epub 2021 May 7.

IRCCS Mondino Foundation, Pavia, Italy.

X-linked parkinsonism encompasses rare heterogeneous disorders mainly inherited as a recessive trait, therefore being more prevalent in males. Recent developments have revealed a complex underlying panorama, including a spectrum of disorders in which parkinsonism is variably associated with additional neurological and non-neurological signs. In particular, a childhood-onset encephalopathy with epilepsy and/or cognitive disability is the most common feature. Read More

Department of Neurology, School of Medical Sciences, University of Campinas (UNICAMP), Rua Tessália Vieira de Camargo, 126. Cidade Universitária "Zeferino Vaz", Campinas, SP, 13083-887, Brazil.

Previous studies using whole exome sequencing (WES) have shown that a significant proportion of adult patients with undiagnosed ataxia in European and North American cohorts have a known genetic cause. Little is known about the diagnostic yield of WES in non-Caucasian ataxic populations. Herein, we used WES to investigate a Brazilian cohort of 76 adult patients with idiopathic ataxia previously screened for trinucleotide expansions in known ataxia genes. Read More

Emerging Disease-Modifying Therapies in Neurodegeneration With Brain Iron Accumulation (NBIA) Disorders.

Front Neurol 2021 15;12:629414. Epub 2021 Apr 15.

Department of Neurology With Friedrich Baur Institute, University Hospital of Ludwig-Maximilians-Universität München, Munich, Germany.

Neurodegeneration with Brain Iron Accumulation (NBIA) is a heterogeneous group of progressive neurodegenerative diseases characterized by iron deposition in the globus pallidus and the substantia nigra. As of today, 15 distinct monogenetic disease entities have been identified. The four most common forms are pantothenate kinase-associated neurodegeneration (PKAN), phospholipase A2 group VI (PLA2G6)-associated neurodegeneration (PLAN), beta-propeller protein-associated neurodegeneration (BPAN) and mitochondrial membrane protein-associated neurodegeneration (MPAN).

Muscle Tone Physiology and Abnormalities.

Toxins (Basel) 2021 04 16;13(4). Epub 2021 Apr 16.

London Movement Disorder Centre, London Health Sciences Centre, University of Western Ontario, London, ON N6A5A5, Canada.

The simple definition of tone as the resistance to passive stretch is physiologically a complex interlaced network encompassing neural circuits in the brain, spinal cord, and muscle spindle. Disorders of muscle tone can arise from dysfunction in these pathways and manifest as hypertonia or hypotonia. The loss of supraspinal control mechanisms gives rise to hypertonia, resulting in spasticity or rigidity. Read More

Engaging Spinal Networks to Mitigate Supraspinal Dysfunction After CP.

Front Neurosci 2021 12;15:643463. Epub 2021 Apr 12.

Department of Neurobiology, University of California, Los Angeles, Los Angeles, CA, United States.

Although children with cerebral palsy seem to have the neural networks necessary to generate most movements, they are markedly dysfunctional, largely attributable to abnormal patterns of muscle activation, often characterized as spasticity, largely reflecting a functionally abnormal spinal-supraspinal connectivity. While it is generally assumed that the etiologies of the disruptive functions associated with cerebral palsy can be attributed primarily to supraspinal networks, we propose that the more normal connectivity that persists between peripheral proprioception-cutaneous input to the spinal networks can be used to guide the reorganization of a more normal spinal-supraspinal connectivity. The level of plasticity necessary to achieve the required reorganization within and among different neural networks can be achieved with a combination of spinal neuromodulation and specific activity-dependent mechanisms.
