The diagnosis of Alzheimer’s disease requires careful analysis of the signs and symptoms of the individual with cognitive decline.1 The available clinical scales can measure general cognitive abilities, comparing scores against those of an average person in the same age group and demographics as the individual with subjective cognitive decline.1 With this, healthcare professionals can confirm the presence of cognitive and functional decline.1

Alzheimer’s disease (AD) is the most prevalent neurodegenerative disease and the leading cause of dementia worldwide, regardless of socioeconomic status.
Dementia is an umbrella term used to describe a state where an individual has lost the ability to carry out daily life activities independently because of cognitive impairment that is not due to an underlying psychiatric condition. Alzheimer’s disease (AD) refers to the abnormal presence of Aβ and tau proteins, which define AD among many other neurodegenerative diseases. Dementia -including dementia due to AD- is likely to be underestimated because of underdiagnosis and misdiagnosis.
