Irrespective of our age, most of us are responsible of claiming, “I must be getting old,” after we can’t fairly discover the phrases to explain one thing or an vital merchandise on our to-do lists slips our minds. Certainly, our brains do change with age; analysis suggests that the mind shrinks about 5% per decade beginning at age 40.
However as we get into our 50s and 60s, what can we anticipate to occur to our brains? What little slip-ups could be attributed to regular mind getting old, and what can signify one thing extra severe? We spoke with docs to search out out:
Mind Modifications To Count on As soon as You Hit Your 50s
In your 50s, your mind is already shrinking. “The cortex ― outer layer of the brain ― becomes thinner, the myelin sheath surrounding the fibers of neurons may begin to degrade, and receptors don’t fire as quickly,” defined Dr. Dylan Wint, a neurologist and neuropsychiatrist on the Cleveland Clinic.
That being stated, most individuals are nonetheless fairly sharp of their 50s — however they could begin to discover some modifications of their cognition. “In your 50s, cognitive functions such as on-demand recall of names and numbers, processing speed, rapid task-switching and spatial skills can diminish,” Wint stated. “This tends to continue in the decades ahead.”
Extra noticeably, throughout this time you would possibly see a delicate decline in what is named episodic reminiscence, or “the mental diary that includes ‘meta-tags,’ such as who was present at a meeting last week and on what day that meeting was held,” Wint stated. “On the upside, other facets of cognition, such as moral judgment, wisdom and emotional regulation, usually continue to improve during this period.”
Dr. Dale Bredesen, a neuroscience researcher on the Pacific Neuroscience Institute, added that hormonal modifications can contribute to cognitive modifications as properly.
“In our 50s, hormonal changes due to menopause in women, and andropause in men, typically occur,” he stated. “Cognitive decline can occur due to a sudden drop in hormones, such as the drop in estradiol associated with menopause. People often find more fat accumulation in the 50s as well, which is associated with cognitive decline.”
As you enter your 60s, Wint stated, mind shrinkage turns into extra noticeable. “Although you retain your lifetime of accumulated knowledge, your brain becomes less efficient at accessing that knowledge and adding to it,” he defined.

Regular Indicators Of An Growing older Mind — And When To Fear
It’s regular to expertise some cognitive decline as we age. However when is forgetfulness an indication of one thing extra severe?
“The most prominent effect of typical aging is probably the slowing of mental processes, particularly coming up with names, switching tasks, changing ingrained habits and incorporating new information,” Wint stated. “Our brains usually compensate for these changes, so we can still function robustly and independently.”
Cognitive decline turns into regarding when it begins to intrude with each day functioning. “This is never normal, and is formally called dementia,” Wint stated. “However, in between typical cognitive aging and dementia is a zone of mild cognitive impairment (MCI), where cognition is not normal for age — formal testing may be necessary to detect this — but does not interfere with routine daily activities. About 50% of people with MCI will progress to develop dementia over the next three to five years.”
If you’re experiencing forgetfulness, bother with communication, or different signs that concern you, Wint recommended that you simply contemplate a session with a geriatrician or neurologist.
“It doesn’t mean you have Alzheimer’s disease or another type of dementia, but a specialist can help to narrow down the cause and any potential treatments or lifestyle changes that may be helpful,” he stated.

It’s also important to stay connected as we age, as a rich in-person social network provides support, reduces stress, combats depression and enhances intellectual stimulation.”
Since many medical situations are strongly linked to a decline in mind perform, sustaining physique well being is a big element of sustaining mind well being.
“Keep your blood pressure and weight at healthy levels, take medication as prescribed, minimize salt and sugar, keep active, and stay socially connected and positive,” Wint stated. “Sleep quality is very important, too, and you should see a professional if your sleep is inadequate in quantity or quality.”
Bredesen added that mind well being must be considered a lifelong purpose, so for those who’re in your 20s or 30s, it’s vital to take steps now.
“Try to avoid processed food, avoid street drugs and heavy alcohol use, avoid smoking ― yes, even vaping ― avoid sleep loss and major stress, and keep your gut microbiome and oral microbiome optimal,” he stated.
