Age-related declines in abstract reasoning ability predict increasing depressive symptoms in subsequent years, according to data from a longitudinal study of older adults in Scotland. The research is published in Psychological Science, a journal of the Association for Psychological Science.
Insomnia is one of the most common symptoms of menopause, with nearly 20 percent of postmenopausal women reporting sleep disturbances. A new study from Korea demonstrates that sleep quality is often worse for women who undergo surgical menopause compared with those who transition through menopause naturally. The study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
A team of neurologists at Georgetown University Medical Center has found that inhibiting the USP13 molecule may be a therapeutic target in Parkinson's disease and other similar forms of neurodegeneration.
What if we could observe genes firing off signals to cause some behaviors? We're getting closer. Researchers were able to directly match gene regulation with ritual mating behavior in fish. Their research field may also give some insight into autism spectrum disorder.
A new brain imaging study of 34 people found that when people expect to feel intense pain, they do, even if they aren't subjected to painful stimuli. Surprisingly, these false expectations can persist even when reality demonstrates otherwise, the study found.
DNA sequences with the potential to form unusual conformations, which are frequently associated with cancer and neurological diseases, can in fact slow down or speed up the DNA synthesis process and cause more or fewer sequencing errors.
The researchers explored the efficacy of a multi-therapy approach based on the disease risk factor status specific to individuals with Alzheimer's disease (AD) diagnosis or concern. The findings indicate previously unidentified connectivity between AD risk factors, suggesting that treatment regimens should be tailored to the individual and multi-modal to simultaneously return several risk factors to a normative state.
The brains of teenage girls who engage in serious forms of self-harm, including cutting, show features similar to those seen in adults with borderline personality disorder, a severe and hard-to-treat mental illness, a new study has found.
Old age is the greatest risk factor for many diseases, including Alzheimer's disease (AD) and cancer. Geroprotectors are a recently identified class of anti-aging compounds. New Salk research has now identified a unique subclass of these compounds, dubbed geroneuroprotectors (GNPs), which are AD drug candidates and slow the aging process in mice.
A new study has identified unique functional brain networks associated with characteristic behaviors of autism spectrum disorder (ASD) in 12- and 24-month old children at risk for developing ASD.
