Your sense of smell is not the same anymore

Losing some of our sense of smell is natural as we grow older, but when it happens prematurely, it can be a sign of illness, including those that affect our brains.

Viral infections, allergies, some medications, and even COVID-19 can lead to a diminished sense of smell. But so can Parkinson's and Alzheimer's, so it’s best to get it checked out by a doctor.
You can’t quite taste foods as you used to

Together with smell comes taste. If you find yourself constantly upping the salt or sugar on your food, then this may be a sign that you are somehow losing your taste. Again, this can be related to diseases that prematurely age the brain.
You are walking slower than you used to

“How fast people are walking in midlife tells us a lot about how much their bodies and brains have aged over time," says Line Jee Hartmann Rasmussen, author of the study ‘Association of Neurocognitive and Physical Function With Gait Speed in Midlife.'
You find it harder and take longer to learn new things

Learning new things and remembering them may seem slightly harder because, in general, older people don’t use their capabilities as often in their daily lives. Still, if you really struggle with this, it might also be a sign of cognitive decline.
Your memory is not the same

If this happens to you, then it is time to seek professional help. This may be a sign of Alzheimer's disease.
You’re depressed

Depression is not directly associated with premature brain aging, but it might indeed be the case. In fact, a study found that the brains of those who suffered depression earlier in their lives age faster later in life.
You get easily distracted

As we age, our brains start to lose receptors and neurons, which can have an impact on focus and concentration. But it turns out we can train our brains to avoid distractions.
You struggle to find the right words

Sure, we’ve all been there, but we’re not talking about the occasional time we couldn’t think of the right word. We're referring to really struggling to remember common words. This may in fact be a symptom of primary progressive aphasia (PPA).
You can’t hear as well as you used to

Hearing loss is a common side effect of aging, but it may also be a red flag, as it puts you at higher risk of developing dementia.
Your eyesight is not the same anymore

Those with vision conditions such as glaucoma and diabetic retinopathy, among others, are at greater risk of developing dementia.
You keep forgetting things

There are many potential causes for forgetfulness, including sleep deprivation as well some medications and illnesses.
Your capacity for multitasking has decreased

Humans are amazing and indeed we can juggle a couple of things at the same time. As we age, we may start to experience some difficulty in switching from one task to the other and back.
You have balance issues when you walk

Wobbling a bit or shuffling your feet when you walk can be symptoms of an array of health issues, including Alzheimer's and Parkinson’s.
You keep losing stuff all the time

Sure, we’ve all misplaced our keys or our phone, but if you keep losing stuff all the time and then finding them in bizarre places (e.g. keys in the fridge), then there might be something wrong.
