What You Can Do to Prevent Alzheimer's | Lisa Genova | TED
TED・2 minutes read
Alzheimer's disease has no cure, with amyloid beta accumulation believed to be the starting point, leading to cognitive decline and the formation of amyloid plaques. Factors like sleep deprivation, cardiovascular health, and cognitive reserve can impact the risk of developing Alzheimer's, but emotional memory and the ability to experience love and joy remain intact even with the disease.
Insights
- The accumulation of amyloid beta in the synapse is considered the initial trigger for Alzheimer's disease, leading to the formation of amyloid plaques and subsequent cognitive decline.
- Cognitive reserve, developed through education and mental engagement, can provide protection against Alzheimer's symptoms, emphasizing the importance of continuous learning and creating robust neural connections to enhance resilience to the disease.

Understanding Alzheimer's Disease: Causes, Detection, and Resilience
- Alzheimer's disease is a prevalent concern as we age, with no cure or disease-modifying treatment available.
- The accumulation of amyloid beta in the synapse is believed to be the starting point of Alzheimer's disease.
- Amyloid plaques form when amyloid beta accumulates excessively in the synapse, leading to cognitive decline.
- The presence of amyloid plaques can be detected through a PET scan before symptoms manifest.
- Sleep deprivation can increase amyloid beta levels, potentially accelerating the onset of Alzheimer's.
- Cardiovascular health, including factors like high blood pressure and obesity, can impact the risk of developing Alzheimer's.
- Cognitive reserve, built through education and mental stimulation, can protect against Alzheimer's symptoms even with the disease pathology present.
- Learning new things and creating rich neural connections can enhance cognitive reserve and resilience to Alzheimer's.
- Despite an Alzheimer's diagnosis, emotional memory and the ability to experience love and joy remain intact.
