Diseases of the nervous system refer to disorders that affect any part of the central nervous system (brain, spinal cord or cranial nerves) or peripheral nervous system.
Using task-based functional MRI, we examined inpatients with heroin use disorder. We found that 15 weeks of medication-assisted treatment (including supplemental group therapy) improved impaired anterior and dorsolateral prefrontal cortex function during an inhibitory control task. Inhibitory control, a core deficit in drug addiction, may be amenable to targeted prefrontal cortex interventions.
Amyotrophic Lateral Sclerosis (ALS) is highly heritable but the mechanisms of sporadic ALS are not fully understood. In this study, the authors identify drivers of variation and disease-relevant changes in the epigenomic profile of iPSC-derived motor neuron lines generated from ALS patients and healthy controls as part of the Answer ALS program.
CSF biomarker concentrations may be influenced by non-disease related interindividual variability. Here, the authors show that reference proteins can capture this variability and enhance the accuracy of Alzheimer’s disease biomarkers.
Using exome sequencing data from one of the largest cohorts of children with cerebral palsy, the genetic diagnostic rates of single-nucleotide and copy number variants were assessed and a sizeable fraction found to be clinically actionable.
Nongenetic factors contribute to the onset, progression and severity of neurodegenerative diseases. Here, the authors describe how exposomics, the systematic analysis of environmental factors, can help neuroscientists understand these diseases.
Claire Durrant reminds us of the importance of studying the physiological roles of proteins and their aggregates to understand their roles in disease and inform therapies, discussing a 2008 paper on amyloid-β from the Arancio lab.
Stephanie Moon discusses findings that revealed that ribosome stalling can lead to the suppression of translation initiation in the brain, delaying the onset of neurodegeneration.

In a multicenter clinical trial, patients with early-stage Parkinson’s disease treated with lixisenatide, a drug currently used for the treatment of diabetes, showed improvement in their motor scores compared with those on placebo.
