Tailoring treatment to men, women may improve survival.
Researchers have unlocked a cure for jet lag by activating VIP neurons in the suprachiasmatic nucleus.
People with Alzheimer’s disease have disturbances in their internal body clocks that affect the sleep/wake cycle and may increase risk of developing the disorder. Researchers at Washington University School of Medicine in St. Louis have found that such circadian rhythm disruptions also occur much earlier in people whose memories are intact but whose brain scans show early, preclinical evidence of Alzheimer’s.
A defective gene linked to autism influences how neurons connect and communicate with each other in the brain, according to a study from Washington University School of Medicine in St. Louis. Rodents that lack the gene form too many connections between brain neurons and have difficulty learning.
Study suggests role of inflammation in brain disease is complicated. Scientists drilling down to the molecular roots of Alzheimer’s disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person’s risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system’s ability to protect the brain from amyloid beta, a key protein associated with Alzheimer’s.
