Subjective Cognitive Decline — A Public Health Issue
Body
Subjective Cognitive Decline (SCD) is the self- reported experience of worsening or more frequent confusion or memory loss.1,2 It is a form of cognitive impairment and one of the earliest noticeable symptoms of Alzheimer’s disease and related dementias.2,3 SCD can have implications for living with and managing chronic disease, or performing everyday activities like cooking or cleaning.2 Because SCD is self-reported, it does not imply a diagnosis of cognitive decline by a health care professional.1,2 Cognition is a combination of processes in the brain that includes the ability to learn, remember, and make judgments.1 When cognition is impaired, it can have a profound impact on an individual’s overall health and well-being.1 Cognitive decline can range from mild cognitive impairment to dementia, a form of decline in abilities severe enough to interfere with daily life.1 Alzheimer’s disease is the most common form of dementia. 1-3 Some cognitive decline can occur as adults age, but frequently forgetting how to perform routine tasks, for example, is not a normal part of aging and can affect a person’s ability to live and function independently. Some people with cognitive decline may be unable to care for themselves or perform activities of daily living, such as meal preparation, managing medical appointments, or managing their personal finances.
