Genetic modifier for Huntington's disease progression identified

Genetic modifier for Huntington’s disease progression identified Researchers have developed a novel measure of disease progression for Huntington’s disease, which enabled them to identify a genetic modifier associated with how rapidly the disease progresses.

Elevated rate of autism symptoms found in children with Tourette syndrome

Elevated rate of autism symptoms found in children with Tourette syndrome Around one in five children with Tourette syndrome, a neurological disorder characterized by involuntary movements and vocalizations, met criteria for autism, a study shows. But this prevalence may be more a reflection of similarity in symptoms than actual autism, according to the study’s researchers. …

Serotonin improves sociability in mouse model of autism

Serotonin improves sociability in mouse model of autism Scientists have linked early serotonin deficiency to several symptoms that occur in autism spectrum disorder (ASD). The study examined serotonin levels, brain circuitry, and behavior in a mouse model of ASD. Experiments showed that increasing serotonergic activity in the brain during early development led to more balanced…

Alzheimer's gene associated with failure to adapt to cognitive challenge in healthy adults

Alzheimer’s gene associated with failure to adapt to cognitive challenge in healthy adults Healthy adults carrying the gene APOE4 — the strongest known genetic risk factor for Alzheimer’s disease (AD) — may struggle to adapt their brain activity to increasing cognitive demands as they get older, according to a study. Alzheimer’s gene associated with failure…

Greater muscle strength, better cognitive function for older people

Greater muscle strength, better cognitive function for older people Greater muscle strength is associated with better cognitive function in ageing men and women, according to a new study. The association of extensively measured upper and lower body muscle strength with cognitive function was observed, but handgrip strength was not associated with cognitive function. Greater muscle…
