Health experts have identified obesity and smoking as key triggers for Alzheimer’s Disease, emphasizing the importance of controlling these factors, especially in young adults. Alzheimer’s is a progressive neurodegenerative disorder that leads to memory loss, cognitive decline, and the inability to perform daily tasks.
According to the experts, obesity and smoking are major risk factors for vascular dementia and can also trigger Alzheimer’s due to the inflammation caused by smoking. Dr. Vikas Mittal, a Pulmonologist at the CK Birla Hospital in Delhi, explained that smoking damages blood vessels, reducing blood flow to the brain, which in turn harms brain cells. Obesity is linked to inflammation and insulin resistance, both of which are detrimental to brain health.
A recent study published in The Lancet revealed that global dementia cases are projected to triple, with an estimated 153 million people living with dementia by 2050. Alzheimer’s, the most common cause of dementia, is expected to see a significant increase as well.
Dr. Anurag Saxena, HOD and Cluster Head Neurosurgery at Manipal Hospital Dwarka, highlighted that obesity can lead to conditions like diabetes and cardiac disease, which are known risk factors for Alzheimer’s. These conditions worsen brain health by promoting inflammation, oxidative stress, and vascular damage, resulting in memory decline and an increased risk of Alzheimer’s Disease.
Furthermore, obesity impairs metabolic functions and insulin signaling, further increasing the risk of neurodegeneration. On the other hand, smoking exacerbates oxidative stress and inflammation in the brain, leading to the development of Alzheimer’s and other forms of dementia.
Dr. Anurag also noted that individuals with a family history of Alzheimer’s are more susceptible to the condition if they smoke. The combination of genetic factors and the effects of smoking can accelerate the progression of Alzheimer’s symptoms.
Dr. Shailesh Rohatgi, HOD of the Department of Neurology at DPU Super Speciality Hospital in Pune, advised maintaining a balanced lifestyle, healthy eating habits, and regular check-ups to prevent the development of vascular dementia. He emphasized engaging in daily activities that stimulate the brain, such as mental exercises and board games.
