New Drug Shows Promise in Slowing Alzheimer's Disease Progression
A recent clinical trial of a drug called Dannanamab by Eli Lilly demonstrated a 35% slowing of cognitive decline in patients with early Alzheimer's disease. This is the most significant result seen so far in Alzheimer's drug trials, which had previously shown little to no benefit. The drug targets tau protein, implicated in the development of Alzheimer's, and showed the most improvement in patients with low to medium tau levels. However, it is important to note that the drug is not a silver bullet and has shown serious side effects, including deaths.
High Lean Muscle Mass Linked to Reduced Alzheimer's Disease Risk
A study conducted using the UK Biobank data suggests that individuals with higher lean muscle mass have a 12% lower risk of developing Alzheimer's disease. This finding adds to the growing evidence that physical fitness and exercise play a crucial role in preventing Alzheimer's. The study hypothesized that the protective effect of lean muscle mass may be attributed to its impact on insulin resistance and the release of myokines like Irisin and BDNF, which have positive effects on brain health. These findings emphasize the importance of maintaining muscle mass and overall fitness to reduce the risk of Alzheimer's disease.
