Cognitive Decline vs Normal Aging
What Qualifies as Normal Aging?
As we age, the brain undergoes many physical changes, which impact our cognitive ability (how well you think, learn, and remember) as illustrated in the Figure below.
Despite physical and cognitive changes in the brain as we grow older, normal aging processes include subtle changes in attention control and speed of thought.Â
What is Cognitive Decline?
Mild Cognitive Impairment (MCI) involves a slight yet detectable decline in memory and thinking skills. Diagnosing MCI can be challenging because its symptoms differ from one individual to another. The cognitive changes linked to MCI are often noticed by the person affected as well as by their close friends and family. However, these changes may not necessarily disrupt everyday activities.
How Does Normal Aging and Cognitive Decline Differ?
The Table below provides some examples of the subtle differences in the symptoms of MCI and normal aging.
If you or a loved one are concerned about cognitive changes, please consult a healthcare professional for assessment and guidance.
