Research into the role of the gut microbiome in modulating brain function has rapidly increased over the past 10 years, albeit chiefly in animal models. Increasing clinical and preclinical evidence implicates the microbiome as a possible key susceptibility factor for neurological disorders, including Alzheimer's disease, autism spectrum disorder, multiple sclerosis, Parkinson's disease, and stroke. ⋯ Longitudinal studies and randomised controlled trials in humans are needed to find out if targeting the microbiome can yield novel therapeutic strategies. Systems biology approaches will also be important in integrating such data with genomic and metabolomic datasets from clinical cohorts with neurological disease to help guide individual treatment selection.

Frontotemporal dementia is a heterogenous neurodegenerative disorder, with about a third of cases being genetic. Most of this genetic component is accounted for by mutations in GRN, MAPT, and C9orf72. In this study, we aimed to complement previous phenotypic studies by doing an international study of age at symptom onset, age at death, and disease duration in individuals with mutations in GRN, MAPT, and C9orf72. ⋯ UK Medical Research Council, National Institute for Health Research, and Alzheimer's Society.

Randomized Controlled Trial
Apomorphine sublingual film for off episodes in Parkinson's disease: a randomised, double-blind, placebo-controlled phase 3 study.
Many patients with Parkinson's disease have potentially disabling off episodes that are not predictably responsive to levodopa. In this study, we assessed the safety and efficacy of apomorphine sublingual film as an on-demand therapy for off episodes in patients with Parkinson's disease. ⋯ Cynapsus Therapeutics and Sunovion.
