For some, cognitive decline manifests as forgetfulness, missing appointments, misplacing items, or struggling with day-to-day tasks like cooking or cleaning. For others, it may affect their ability to focus or even enjoy life as much as they used to. The level of struggle depends on how much the decline has progressed. There are different types and stages of cognitive decline, ranging from mild to severe.
I covered the scientific details in a story titled How to Slow Down Subjective and Objective Cognitive Decline: Better cognitive function, health, and performance for the aging population with proactive lifestyle changes. As I pointed out in the previous story, loved by many of my readers, scientists break it down into two main types: subjective and objective.
Subjective cognitive decline is when you feel like your memory or thinking is worsening, but a doctor hasn’t confirmed it yet. On the other hand, objective cognitive decline is when medical experts diagnose these problems based on tests like MRI, CT scans, or other evaluations.
The most common condition related to cognitive decline is dementia, with Alzheimer’s being the form we hear about most often. Over six million Americans live with Alzheimer’s, and while there’s no cure yet, there is significant evidence that healthy lifestyle choices and early intervention can help slow it down. I even heard some people reverse these conditions, but the evidence is not empirical yet and more anecdotal from my research. I remain optimistic and open-minded.
If cognitive decline keeps progressing, it can turn into something more serious: cognitive impairment. This is when it becomes hard to do basic things like remember names, follow conversations, or even recognize people. People with cognitive impairment often experience mood swings or confusion and may need help from others to get through the day.
This topic matters because cognitive decline is not just about memory loss — it impacts daily life and independence. People dealing with these issues rely on family or professional care, which can be challenging emotionally and financially. Studies show that the medical costs for individuals with cognitive issues can be much higher. And with the number of older adults facing severe cognitive challenges expected to double by 2060 in the U.S., this isn’t just a personal issue — it is a societal one.
