Subjective Cognitive Decline
What is Subjective Cognitive Decline (SCD)
SCD is not a diagnosable disorder, however is usually when an individual first recognizes changes in memory and thinking abilities. It has long been recognized as an early predictive indicator of dementia.
For many years, a person may have normal cognitive performance while developing the pathology of Alzheimer’s Disease such as amyloid beta and tau proteins. At some point, the person may recognize the signs subjectively, hence the term subjective cognitive decline.
In this video by our very own Mark Osborn, you’ll take a quick dive into the science behind SCD and what it means to you.
What does SCD tell us about the brain?
Based on studies, SCD is a sensitive and non-invasive predictor of future amyloid accumulation and early neurodegenerative changes and may double one’s risk for progression to MCI or dementia.
Are there other risk factors?
In addition to SCD being well established as a significant risk factor for dementia, there are a number of other factors that when combined with SCD, increase the risk of MCI and dementia even further.
These risk factors are:
Feeling worried about one’s cognitive decline
The change has occurred within the last two years
Being greater than 60 years old
Confirmation of decline by a close friend or family member
Being a carrier of at least one APOE4 allele (your genetics)
