A Harvard-trained neuroscientist has revealed that no supplement or pill can prevent Alzheimer's disease, but certain lifestyle changes are just as effective as any medication in development. Lisa Genova, a bestselling author with a PhD in Neuroscience from Harvard University, shared her advice in an Instagram video for @Bigthinkers.
No Magic Pill for Alzheimer's Prevention
Speaking directly to the camera, Genova explained that for 98% of people, Alzheimer's is not inevitable. “Our risk of developing Alzheimer's is a combination of the genes we've inherited from mum and dad, and how we live,” she said. She emphasized that lifestyle factors such as sleep, diet, exercise, stress management, and learning new things play a crucial role.
“These aren't particularly sexy, but they work,” Genova stated. “The good news is that a lot of these lifestyle factors work as well as any pill that we might develop for preventing Alzheimer's. We just have to do them.” She noted that people frequently ask her for a supplement, but she insists that no such pill exists.
Risk Factors for Alzheimer's Disease
According to the NHS, Alzheimer's disease is a progressive condition that develops gradually over many years. The exact cause is not fully understood, but several factors increase risk: age, a family history of the condition, untreated depression, and lifestyle factors associated with cardiovascular disease.
The NHS also lists smoking, obesity, diabetes, high blood pressure, and high cholesterol as risk factors. Additionally, hearing loss, loneliness, and a sedentary lifestyle may contribute, though they are not necessarily direct causes.
How to Reduce Your Risk
The NHS recommends the following steps to lower Alzheimer's risk: stopping smoking, eating a healthy balanced diet, staying physically and mentally active, maintaining a healthy weight, limiting alcohol consumption, and having regular health checks as you age.
Genova's advice aligns with these recommendations. She urges people to implement these lifestyle changes consistently, as they are the most effective strategy currently available for reducing dementia risk. The NHS confirms that Alzheimer's is the most common cause of dementia in the UK.
Always consult your GP if you have concerns about your health or memory.
