Alzheimer's disease is a complex neurological disorder that affects millions of people around the world. While there is no single known cause of the condition, researchers have identified several risk factors that can increase the likelihood of developing it. Age is the most important factor, and the risk of Alzheimer's disease doubles approximately every five years after the age of 65. Other risk factors include genetics, lifestyle, and environment. Age is the main risk factor for Alzheimer's disease, and it is impossible to change. However, there are other factors that can be influenced.
People who lead a healthy lifestyle, especially starting in middle age (40 to 65 years old), are less likely to develop Alzheimer's disease. This includes not smoking, not drinking too much alcohol, and following a healthy, balanced diet. The ApoE-E4 gene also plays a role in increasing the risk of Alzheimer's disease. People with this gene, along with a family history of the disease, are more likely to develop Alzheimer's than those without it. Although there is no sure way to prevent Alzheimer's disease, there are steps that can be taken to reduce the risk. Eating a nutritious diet, exercising regularly, and avoiding smoking and excessive alcohol consumption can all help reduce the risk of developing Alzheimer's disease.
