Many believe that engaging in novel and mentally challenging activities promotes brain health and prevents Alzheimer's disease in later life. However, mental stimulation may also have risks as well as benefits. As neurons release neurotransmitters, they often also release amyloid peptides and tau proteins into the extracellular space. These by-products of neural activity can aggregate into the tau tangle and amyloid plaque signatures of Alzheimer's disease. Over time, more active brain regions a...

Abstract null Abnormally phosphorylated tau, an indicator of Alzheimer’s disease, accumulates in the first decades of life in the locus coeruleus (LC), the brain’s main norepinephrine supply. However, technical challenges in reliable in-vivo assessments have impeded research into the role of the LC in Alzheimer’s disease. null We studied participants with or known to be at-risk for mutations in genes causing autosomal-dominant Alzheimer’s disease (ADAD) of early onset, providing a unique window ...
