Some individuals are resilient to developing Alzheimer’s disease despite having biological markers of the disease. Alzheimer’s is caused by a buildup of proteins in the brain that leads to neuron death and cognitive decline. A study found that genes related to the immune system may play a role in resilience to Alzheimer’s symptoms. Lifestyle changes such as physical activity can also reduce the risk of developing the disease. Resilient individuals may have genes that aid in clearing these toxic proteins from the brain. Understanding genetic and lifestyle factors can help reduce the risk of Alzheimer’s disease even in those without resilient genes.
