Experts Say Changes in Your Sense of Smell May Be Linked to Early Cognitive Changes
Many people enjoy the comforting scent of their favorite soap, shampoo, or shower gel without giving it much thought. However, if that familiar fragrance suddenly seems weaker or disappears altogether, it may be worth paying attention. Health researchers note that subtle changes in the sense of smell can sometimes provide early clues about changes in brain health. According to Professor Davangere Devanand, a psychiatrist and neurologist at Columbia University, difficulty recognizing familiar scents may occasionally be linked to early signs of cognitive decline. Because the sense of smell is closely connected to areas of the brain responsible for memory and emotions, small changes in how a person perceives everyday scents can appear before other noticeable symptoms.
Scientists have spent many years studying the relationship between smell and brain function. The olfactory system, which processes scents, communicates directly with important brain regions such as the hippocampus and amygdala. These areas help manage memory, emotional responses, and learning. Interestingly, these same regions are among the first to be affected in certain neurological conditions, including Alzheimer’s disease. When the brain begins to struggle with processing smell signals, people may notice that scents they once recognized easily—such as soap, coffee, perfume, or freshly cooked food—become harder to identify or feel less distinct than before.
Changes in smell are not limited to the bathroom or personal care products. Some individuals report that food aromas seem weaker, flowers or perfumes become difficult to distinguish, or multiple scents start to smell similar. It is important to remember that many common and harmless factors can also affect the sense of smell. Temporary illnesses such as colds, sinus infections, allergies, or even certain medications may reduce the ability to detect scents. In many cases, these changes improve once the underlying issue resolves. However, if the loss of smell persists without an obvious explanation, experts recommend discussing it with a healthcare professional.
Researchers continue to explore the role of smell in detecting early neurological changes. Studies from Columbia University have shown that older adults who struggle to identify common scents may face a higher likelihood of experiencing cognitive decline later on. Because of these findings, smell identification tests are being studied as a simple and non-invasive tool that may help doctors notice potential concerns earlier. Experts emphasize that a change in smell alone does not mean a serious condition is present. Still, paying attention to subtle signals from the body and seeking professional advice when something unusual persists can be an important step in supporting long-term brain health.
While holding my newborn after a C-section, I texted my parents, “Please, can someone come help me?” Mom read it and said nothing, because she and Dad were boarding a luxury anniversary cruise with my sister, the golden child.
Six days later, Dad tried to withdraw $2,300 from my account to pay their cabin upgrade. What I did next destroyed their world by turning every secret they had buried into evidence.
While holding my newborn after a C-section, I texted my parents, “Please, can someone come help me?”
My mother read it, said nothing, and thirty minutes later posted a smiling photo from the deck of a luxury anniversary cruise, one arm around my sister, Chloe, the golden child.
I stared at the picture from my hospital bed while my son slept against my chest, his tiny fist curled under his chin. My incision burned every time I breathed. My milk had not fully come in. The nurse had just told me I could not lift anything heavier than the baby, which was almost funny, because I had no one to lift anything else.
My husband, Daniel, was deployed overseas. My best friend was out of state. So I had done the humiliating thing. I had asked my parents for help.
My mother, Eleanor, replied the next morning with one sentence:
You’re a mother now, Nora. Figure it out.
Two minutes later, Chloe sent a photo of herself in a white swimsuit beside a champagne bucket:
Don’t be dramatic, Nora. Mom and Dad deserve joy too.
I did not answer. I changed my son’s diaper with shaking hands, signed my discharge papers alone, and paid for a ride home because my father, Arthur, had “forgotten” I was leaving the hospital that day.
By the sixth day, I had learned to stand up from bed without crying out. I had learned to warm bottles with one hand. I had learned that loneliness had a sound: the soft buzz of a phone nobody answered.
Then my bank app flashed red.
Attempted withdrawal: $2,300
Location: Caribbean Sea ATM
Cardholder: Arthur Vance
My father.
For a few seconds, I simply stared. Then another alert appeared.
Security question failed. Second attempt pending.
My son whimpered in his bassinet. I leaned over, kissed his forehead, and whispered, “Not this time.”
Because my parents thought I was still the daughter who apologized when they stole from her college fund. They thought I was still the girl who stayed silent when Chloe used my name to open store cards. They thought childbirth had made me weak.
They had forgotten what I did for a living.
I was a fraud compliance analyst for Meridian National Bank. I had spent seven years tracing stolen identities, forged signatures, fake hardship claims, and families who smiled in public while bleeding one another dry.
And three months before my son was born, I had copied every document they thought I would never understand.
I did not call my father. I did not scream at my mother. I did not send Chloe a furious message she could screenshot and use to call me unstable.
I opened my laptop at the kitchen table, still moving slowly from surgery, and began building a file.
First: The attempted withdrawal, time, terminal ID, failure code, and location.
Second: The card my father had no legal right to possess.
Third: The old emails Chloe had sent me while pretending to “help” with family taxes.
Buried inside those emails were scanned copies of my driver’s license, my Social Security card, and my signature on blank authorization forms. My parents had always called it “family paperwork.”
I called it evidence.
At noon, Mom finally texted:
Your father said your card declined. Why are you embarrassing us on vacation?
I replied, “Why was Dad using my card?”
The answer came from Chloe:
Because you owe them. They raised you. Don’t act rich just because you married a soldier and got a bank job.
Then Dad called. I let it go to voicemail.
His voice came through loud and irritated. “Nora, unlock the account. We need the upgrade today. Don’t start your nonsense while your mother is trying to enjoy herself. You have money sitting there. We only need twenty-three hundred.”
He paused, then added the sentence that sealed him.
“And don’t forget, I still have access to the trust documents. If you make trouble, you’ll never see a dime of your grandmother’s house.”
My grandmother’s house. The one she had left to me. The one my parents claimed had been sold years ago to pay “family debts.”
I had suspected the truth for months. During my pregnancy, a county property-tax notice had arrived by mistake with my name listed as beneficiary under the Vance Family Trust. When I asked Mom, she snatched the envelope from my hand and said, “Pregnancy brain makes you paranoid.”
But pregnancy brain had not stopped me from requesting certified copies. It had not stopped me from hiring a quiet estate attorney with overtime money. It had not stopped me from learning that my parents had forged trustee amendments, rented out the house, and deposited the income into an account Chloe used for her boutique.
The cruise was not an anniversary gift. It was paid from stolen rent.
That night, Chloe posted a video from the ship’s dining room. “To family who chooses happiness,” she toasted, raising a glass. “Not guilt.”
Dad leaned into the camera. “Some people always play victim,” he said. “But this family rewards loyalty.”
I saved the video. Then I sent one email to my attorney, one to Meridian’s fraud escalation team, and one to the trust department listed in my grandmother’s original documents.
At 9:14 p.m., my father tried the ATM again. This time, the account did not simply decline.
It froze.
The confrontation happened over video call the next morning. Mom appeared first in a cruise robe, her face tight with rage. Chloe stood behind her. Dad shoved into frame last.
“What did you do?” he snapped.
I sat in the nursery with my son asleep against my shoulder. “I reported unauthorized access to my bank account.”
Dad laughed. “You reported your father?”
“I reported a man who tried to steal from a woman six days after surgery.”
Mom’s mouth twisted. “Always dramatic.”
I clicked a key. “I also reported identity theft, forged documents, and trust fraud.”
The cabin went silent. Chloe’s face changed first. Not guilt. Calculation.
“You have no proof,” she said.
“I have the ATM logs, Dad’s voicemail, your emails with my identification documents, the store cards opened under my name, the forged trust amendments, and rental deposits from Grandma’s house going into your business account.” I paused. “And your cruise video.”
Dad’s skin went gray.
Mom grabbed the phone. “Nora, stop. We can talk when we get home.”
“No,” I said. “You had six days to talk. You read my message while I was bleeding through bandages and holding your grandson. You chose champagne.”
Chloe tried to laugh. “You’re exhausted. Emotional. You just had a baby.”
That was when my attorney joined the call. Claire Benton’s name appeared, and Chloe stopped smiling.
Claire’s voice was lethal. “The court suspended your control over the Vance Family Trust. The rental accounts are frozen. Chloe’s boutique account is under review because it received traceable trust funds.”
Mom whispered, “Boutique account?”
Chloe looked away.
Claire continued, “Meridian opened a fraud case. Authorities have been notified. Do not contact my client except through legal channels.”
Dad exploded. “She is our daughter!”
I held my son closer. “No. I was your source of money. There’s a difference.”
Three weeks later, they came home to changed locks on my grandmother’s house and a legal notice on the door.
The rent was redirected to the trust account. Chloe’s boutique lost its lease when frozen funds exposed unpaid loans and false income statements. Dad was forced into early retirement after his employer learned of the complaint. Mom sold jewelry for legal fees and still called me cruel.
At the hearing, my father would not look at me. Chloe cried until the judge told her to stop performing. My mother stared at my baby like she had suddenly remembered he existed.
The judge restored control of the trust to me, ordered repayment, and referred the forged documents for prosecution.
Six months later, I stood on the porch of my grandmother’s house with my son on my hip. Daniel was home, his hand warm at my back.
My phone buzzed with one message from Mom:
We’re still your family.
I looked at my son, laughing in the sunlight. I typed back one sentence:
Family comes when you ask for help.
Then I blocked her, stepped inside, and closed the door on the quietest peace I had ever known.
