The expression of many genes that have previously been associated with autism is abnormal also in violent psychopathy, a new study shows. The researchers used stem cell technology to analyse the expression of genes and proteins in the brain cells of psychopathic violent offenders. Published in Molecular Psychiatry, the findings may open up new avenues […]
Researchers at the German Center for Neurodegenerative Diseases (DZNE) and the Institute for Stroke and Dementia Research (ISD) at the University Hospital of the Ludwig-Maximilians-Universität (LMU) in Munich have found that a protein called TREM2 could positively influence the course of Alzheimer’s disease. When TREM2 is present in the cerebrospinal fluid at higher concentrations, patients […]
Brain-selective estrogen treatment improves the symptoms of Parkinson’s disease in male mice, according to new research published in JNeurosci. These findings may help explain the sex differences in Parkinson’s disease and could lead to estrogen-based treatments. Parkinson’s disease is characterized by the death of neurons involved in movement, which may be partially caused by gene […]
While the presence of beta-amyloid plaques in the brain may be a hallmark of Alzheimer’s disease, giving patients an amyloid PET scan is not an effective method for measuring their cognitive function, according to a new study from researchers in the Perelman School of Medicine at the University of Pennsylvania and Thomas Jefferson University. The […]
Neurodevelopmental disorders arising from rare genetic mutations can cause atypical cognitive function, intellectual disability, and developmental delays, yet it is unclear why and how this happens. Scientists suspected a mutation in a complex of proteins could be the culprit for a group of rare genetic disorders and, now, Salk Institute researchers have identified the molecular […]
Although psychiatric disorders can be linked to particular genes, the brain regions and mechanisms underlying particular disorders are not well-understood. Mutations or deletions of the SHANK3 gene are strongly associated with autism spectrum disorder (ASD) and a related rare disorder called Phelan-McDermid syndrome. Mice with SHANK3 mutations also display some of the traits associated with […]
When faced with emotional challenges or traumatic experiences, we may well have different, mixed feelings both at the same time and sequentially. In adolescence, when complex emotions are experienced as part of everyday life, the effect of challenge or trauma combined with difficulty expressing emotional complexity can exacerbate a given situation and limit the communication […]
There are currently no drugs that stop or inhibit Alzheimer’s disease. Despite drug trials showing plaque reduction in the brain, the patients’ cognitive function did not improve. Would the results be different if it were possible to design studies that intervene much earlier on in the disease, before cognition is affected? This is what an […]
Having aspirations helps us navigate life in a meaningful and fulfilling way, but it can also cause psychological distress when hopes are left unfulfilled. New Edith Cowan University (ECU) research has found that it’s not failing to make progress toward our ‘ideal-self’ that is problematic but rather the tendency to focus on that lack of […]
An Osaka University-led research team has recently published findings that provide a ray of hope for the millions of Parkinson’s disease (PD) sufferers worldwide. Although more common in those aged over sixty, PD can strike at any age, with an estimated prevalence of 41 per 100,000 people in their forties. And while not fatal in […]
