‘Rejuvenating’ the Alzheimer’s Brain

MicroRNA-132 regulates neurogenesis in the hippocampus, according to both mouse and human tissue studies. Restoring levels of microRNA-132 in mouse models of Alzheimer's disease reduces neurogenetic deficits and restores cognitive abilities, researchers say.

A Complex Link Between Body Mass Index and Alzheimer’s

While there is an association between obesity during midlife and an increased risk of Alzheimer's disease, researchers say the link doesn't necessarily extend into later life. A new study revealed higher genetic risk for Alzheimer's and lower BMI, especially in older men, was linked to an increased risk of Alzheimer's disease and predicted the disease progression.

New Insight Into Protein Production in Brain Could Help Tackle Dementia

Researchers have identified a layer of genetic material involved in controlling the production of tau in the brain. The material is part of a larger family of non-coding genes that regulate and control other brain proteins associated with neurodegenerative disorders, such as Alzheimer's disease, Parkinson's, and PSP. The findings could lead to the development of new therapeutics to treat a range of neurodegenerative disorders.

Anesthetic May Affect Tau Spread in the Brain to Promote Alzheimer’s Disease Pathology

Sevoflurane, an anesthetic, causes tau to leave neurons and enter microglia. This stimulates the production of interleukin-6, leading to inflammation and cognitive impairment.

Dementia Linked to Smoking and Cardiovascular Disease

A new large-scale study links smoking and cardiovascular disease to an increased risk of developing dementia. Smoking and cardiovascular disease impact memory and learning throughout adulthood, starting at age 18. Researchers say smoking has the biggest impact on cognitive function in women, while cardiovascular disease has a more detrimental impact on cognition in men.
