To effectively reduce the probability of getting dementia, it is crucial to grasp what dementia is, understand its frequency in the population, and recognize the risk factors associated with it.

Defining Dementia and Alzheimer’s Disease

Dementia is an umbrella term describing a set of symptoms affecting memory, cognitive function, and the ability to perform everyday activities. Alzheimer's disease is the most common cause of dementia, involving the degeneration of brain cells that leads to a progressive decline in cognitive abilities.

Epidemiology: Incidence and Prevalence

The incidence of dementia refers to the rate of new cases in a given period, while prevalence represents the total number of people living with the condition at a specific time. Both incidence and prevalence of dementia increase significantly with aging.

Risk Factors for Dementia

Risk factors for dementia can be divided into modifiable and non-modifiable categories. Genetic factors and family history are non-modifiable risks, with certain genes increasing the likelihood of developing Alzheimer's disease. Modifiable risks include lifestyle choices and medical conditions that may predispose individuals to cognitive decline.

Lifestyle and Dementia Prevention
