Three scientists with high-risk APOE4-4 genes are taking proactive steps to protect their brain health through lifestyle changes, participation in clinical trials, and advocacy for more research and drug development, highlighting the importance of personalized approaches in Alzheimer's prevention and treatment.
A new study links impaired cholesterol transport to neurons with Alzheimer's disease, especially in individuals with the APOE4 genetic variant, suggesting cholesterol's role in brain health and potential avenues for prevention.
A new study links impaired cholesterol transport to neurons with Alzheimer's disease, especially in individuals with the APOE4 genetic variant, suggesting potential new avenues for understanding and preventing the disease.
The article discusses the implications of discovering your genetic risk for Alzheimer's disease, particularly the APOE4 gene, highlighting that while genetic testing can inform about increased risk, lifestyle choices such as sleep, exercise, diet, and inflammation management play a crucial role in mitigating this risk. It emphasizes that genes are not destiny and encourages proactive health habits regardless of genetic results.
The European Medicines Agency's human medicines committee has recommended Leqembi (lecanemab) for treating early Alzheimer's disease in patients with one or no copies of the ApoE4 gene, due to a lower risk of amyloid-related imaging abnormalities (ARIA). This decision follows a re-examination of data showing Leqembi's benefits in slowing cognitive decline outweigh its risks in this restricted population. The recommendation includes safety measures like MRI monitoring and a controlled access programme to mitigate ARIA risks. The decision now awaits approval from the European Commission.
A study published in Nature reveals that APOE4 exacerbates the formation of lipid droplets in microglia, particularly in individuals with Alzheimer's disease. This lipid accumulation is linked to the overexpression of an enzyme involved in triglyceride synthesis, and APOE4/4 microglia were found to release neurotoxic substances, potentially including the triglycerides themselves. The study suggests that APOE4/4 microglia may be detrimental to neurons and could play a role in the progression of Alzheimer's disease.
Researchers at the University of Colorado Alzheimer's and Cognition Center have discovered that a drug called GM-CSF, already approved for rheumatoid arthritis, can reverse Alzheimer's disease. In addition, two commonly used psychiatric drugs, imipramine and olanzapine, were found to block the effects of a protein known as APOE4, which significantly increases the risk of developing Alzheimer's. These findings offer hope for more personalized care and the development of effective treatments for Alzheimer's patients.
