Study reveals how the brain's opioid system is linked to mood changes associated with depression and anxiety. Neuroimaging revealed, in those with depression, there is a decreased number of opioid receptors in specific areas of the brain.
Genetic analysis of almost 4,300 samples reveals a link between the appearance of amyloid deposits, APOE, and a novel gene called RBFOX1. Lower levels of RBFOX1 in the brain appear to be associated with increased amyloid and global cognitive decline over a person's lifetime.
According to a new study, the number of opiate receptors in the brain increases in order to combat severe pain in arthritis sufferers.
Smokers may have reduced neuroimmune function compared to their non-smoking peers. Researchers report restoring the immune system may benefit smokers. Immune dysfunction is linked to cognitive dysfunction.
Researchers discover a decline in glucose levels in the brain that occurs during the early stages of MCI.
Researchers report they have discovered where the earliest signs of Alzheimer's may occur in the brain. Initial accumulation of Alzheimer's associated amyloid beta was discovered in an important functional network, the default mode network.
A new study reveals sleep deprivation can lead to an immediate increase in amyloid beta.
A new study reports people with insulin resistance, a feature common in type 2 diabetes, can increase the risk for developing Alzheimer's disease.
According to a new study, slow walking speed may signify a build up of amyloid plaques in elderly people, even if they do not have other symptoms of Alzheimer's disease.
