Alzheimer’s disease (AD) is the most common dementia. It is a progressive neurological disorder that affects primarily memory, thinking, and behavior. Its pathogenesis is impacted by a variety of environmental and inherited variables, and it is difficult to identify the early events that result in the outbreak of the disease. In this article, we will discuss some common health issues linked to a higher probability of appearing later in life. We will also discuss the importance of using biomarkers that can help with diagnosis and prognosis, as it is the most common dementia among the elderly. This article will focus on the key elements that must be considered when examining dementia, especially in the elderly, together with neuroimaging, vascular risk factors, localized neurological symptoms, and the Hachinski ischemia score.
