Alzheimer's disease (AD) is the most common type of dementia and typically manifests as a progressive loss of memory and cognitive function and the development of language and visuospatial skills deficiencies, and behavioral disorders such as apathy, aggressiveness and depression. However, acquired risk factors such as cerebrovascular diseases, diabetes, hypertension, obesity and high cholesterol increase the risk of Alzheimer's development. Some protective factors associated with a lower risk of disease incidence, such as cognitive reserve, physical activity and diet are suggested.
