Recent studies have found a link between P. gingivalis, bacteria that plays a significant role in periodontal disease, and an increased risk of Alzheimer's disease. A new study reports SCPPPQ1, a protein expressed in the cells of the junctional epithelium, has antibacterial potential and could slow, or even destroy P. gingivalis.
Young boys who play sports are less likely to develop depression, anxiety, and emotional distress later in childhood, researchers say. Additionally, boys who experience less emotional distress during middle childhood are more likely to be physically active during adolescence.
Children whose parents use "harsh" punishments, such as spanking, have smaller brain structures during adolescence. The decreased size was most noticeable in the amygdala and prefrontal cortex, two areas of the brain associated with emotional processing and the emergence of depression.
Hyperactivation in specific brain areas may be an early biomarker for Alzheimer's disease. Researchers found those who reported concerns over diminished memory skills, and with other risk factors for Alzheimer's, showed signs of hyperactivation in brain areas prior to the diagnosis of dementia.
Researchers have made an important discovery about the mechanisms behind learning and memory. Depending on the number of synapses, and their proximity, information is processed and stored differently.
High school aged girls who use marijuana experience a greater impact on their working memory and academic success than their male peers.
A new meta-analysis of autism data reveals the difference between people diagnosed with autism and the general population is shrinking. Measurable differences between people with ASD and people not on the spectrum has decreased over the past 50 years. Researchers say the definition of autism may be getting too blurry to be meaningful, and the condition may be at risk of being trivialized.
Mice infected with bacteria that cause mild intestinal infections exhibited Parkinson's like symptoms later in life. The findings provide a pathophysiological model in which intestinal infections may act as a trigger for Parkinson's disease.
A new study reports children on the autism spectrum who participate in musical activities have significantly improved social communication skills than those who are not exposed to music therapy.
