The exacerbation begins with the disease seen with the symptoms like deterioration of mental ability, memory, and cognitive deficits, which ultimately decline the physical activity also, and the severity of this disease causes the death of the patient. There is no proper medication and cure available to date, which can precisely prevent the condition efficiently. But it is essential to diagnose it before its destructive phase and consult for necessary treatments and procedures taken by the patient and the caregivers. Apart from clinical trials, the first and foremost thing is to focus on lifestyle; a way of living can have a more significant impact on a person's health. One can stay healthy for a longer time or fight against the disease by developing strategies like boosting immunity and staying physically fit enough, or else, one can successfully delay the appearance of disease with strong immunity and a healthier lifestyle. And the other promising fact is taking nutritious food, which is helpful to build a robust internal defense system against the diseased condition and lowering the risk of ailments. This chapter will focus on the pathophysiology of Alzheimer's disease, lifestyle modifications, and nutritional interventions in AD. � 2023 Elsevier Inc.
