| Researchers question prevailing Alzheimer's theory with new discovery Posted: 28 Jun 2021 02:06 PM PDT Experts estimate more than 6 million Americans are living with Alzheimer's dementia. But a recent study sheds new light on the disease and a highly debated new drug therapy. |
| Evidence-based patient-psychotherapist matching improves mental health care Posted: 28 Jun 2021 02:06 PM PDT Psychotherapy researchers have found that mental health care patients matched with therapists who had a strong track record of treating the patients' primary concerns had better results than patients who were not so matched. |
| 'Unexciting' an anxious brain: Novel drug reduces anxiety-like behavior in mice Posted: 28 Jun 2021 02:05 PM PDT Anxiety is considered a natural response to stress. However, a state of heightened anxiety, called anxiety disorder, prevents thousands of people from living their best lives. While several underlying mechanisms have been therapeutically targeted, much remains to be discovered about this disorder. In an effort to get closer to unraveling the mechanisms that govern this condition, researchers have identified a drug that reduces glutamate-induced neurotransmission, involved in anxiety-like behavior. |
| GluN3A knockout mouse: Alternative model for Alzheimer's neurodegeneration Posted: 28 Jun 2021 02:04 PM PDT GluN3A-deficient mice display all aspects of Alzheimer's neurodegeneration. |
| The most curious babies become the most curious toddlers Posted: 28 Jun 2021 12:29 PM PDT A longitudinal study of infant curiosity found that months-old babies most captivated by magic tricks became the most curious toddlers, suggesting a pre-verbal baby's level of interest in surprising aspects of the world remains constant over time and could predict their future cognitive ability. |
| Blood stem cells make brain tumors more aggressive Posted: 28 Jun 2021 10:21 AM PDT Scientists have discovered stem cells of the hematopoietic system in glioblastomas, the most aggressive form of brain tumor. These hematopoietic stem cells promote division of the cancer cells and at the same time suppress the immune response against the tumor. This surprising discovery might open up new possibilities for developing more effective immunotherapies against these malignant brain tumors. |
| Love: How the feeling of power determines happy relationships Posted: 28 Jun 2021 10:21 AM PDT Want to have a happy relationship?

Instead, how lovers perceive power dynamics in their relationship is most important for relationship satisfaction. |
| Scientists develop simple blood test for early detection of Alzheimer's disease Posted: 28 Jun 2021 09:49 AM PDT An international research team has developed a simple but robust blood test from Chinese patient data for early detection and screening of Alzheimer's disease (AD) with an accuracy level of over 96%. |
| Saturated fatty acid levels increase when making memories Posted: 28 Jun 2021 09:30 AM PDT Saturated fatty acid levels unexpectedly rise in the brain during memory formation, according to new research. |
| Gene discovery may hold key to better therapies for OCD Posted: 28 Jun 2021 08:41 AM PDT New research finds that some cases of OCD are caused by damaging gene variants that, while rare, provide a needed starting point for the development of better therapeutics. |
| Posted: 23 Jun 2021 07:03 AM PDT A stressful workplace can take its toll on our mental health, and new evidence backs up this belief. A year-long population study reveals that toxic workplaces can increase full-time workers' risk of depression threefold. |
| Subconscious changes in movement may predict Alzheimer's disease Posted: 23 Jun 2021 06:11 AM PDT A research team found that FMAR was associated with preclinical AD pathology in women, suggesting that FMAR may be a new biomarker for AD before cognitive symptoms begin. |
