Hippocampal neurogenesis continues to occur well into old age, and in those with Alzheimer's disease. Researchers found evidence of neurogenesis in people up to the age of 99. While neurogenesis continues to occur in those with Alzheimer's disease, it is significantly reduced compared to those who have normal cognitive function.
Researchers have identified a new target of alcohol in the brain. A new study reveals alcohol blocks the KCNK13 potassium channel within the membrane of dopamine releasing neurons in the ventral tegmental area.
Pregnant women exposed to nitrates through household drinking water had, on average, babies that weighed ten grams less than women with no exposure to nitrates in drinking water. High levels of nitrate in tap water can cause infant methemoglobinemia, a fatal condition in newborns.
Investigating 32 key nutrients in the Mediterranean diet, researcher report aging individuals with more abundant key nutrients in their blood had better functional connectivity and improved cognitive performance than those lacking the nutrients.
Researchers investigate whether abnormal gut bacteria composition contribute to autism spectrum disorders, or whether diet and medication for children with ASD leads to the irregular microbiome.
A new study in PNAS reveals how the body converts omega 3 fatty acids into endocannabinoids, which can have anti-inflammatory effects.
Researchers say almost one third of Americans are unknowingly taking medications that can increase depression and suicide risks.
Researchers report genes implicated in human ASD are regulated differently in honeybees that are more unresponsive than their nest mates. The PNAS study provides insight into the genetic heritage shared across species and offers clues about the evolution of social behavior.
Researchers report rats exposed to phthalates, both while in the womb and through lactation, had fewer neurons and synapses than peers who were not exposed to the plasticizing chemicals. Additionally, the phthalate exposed rats showed deficits in cognitive flexibility.
A new mouse study reveals long term exposure to bacteria associated with periodontal disease causes neuroinflammation and neurodegeneration, leading to similar effects of Alzheimer's disease. Researchers report periodontal disease may be an initiator of Alzheimer's.
