An early sign of Alzheimer’s disease can be noticed while taking a shower: what should you look out for?
While memory loss is the most recognized symptom of Alzheimer’s disease, new research suggests a subtler sign may appear first: the loss of smell. According to Professor Davangere Devanand of Columbia University, struggling to recognize familiar scents—like your usual shower gel—could signal early cognitive decline.
Smell is deeply connected to memory. The brain regions responsible for scent recognition are often among the first affected in early Alzheimer’s.
In a long-term study involving over 1,000 participants, researchers used a simple smell test to detect warning signs. Participants were asked to identify 12 common scents such as soap, smoke, rose, and leather.
Those who scored below 8 out of 12 were significantly more likely to develop cognitive impairment over time.
This basic smell test, especially when combined with a short memory assessment, proved as effective as MRI scans and more complex evaluations.
It’s also affordable, non-invasive, and could be used in routine doctor visits to flag early warning signs.
Key scents to pay attention to include soap, gas, lilac, lemon, cherry, and menthol. If you consistently fail to recognize several—particularly familiar ones—it may be worth discussing with your doctor.
Your shower might reveal more about your brain health than you realize.
My Grandpa Raised Me Alone – After His Funeral, I Learned His Biggest Secret
Two weeks after my grandfather's funeral, my phone rang with a stranger's voice saying words that made my knees buckle: "Your grandfather wasn't who you think he was." I had no idea the man who raised me had been hiding a secret big enough to change my entire life.
I was six years old when I lost my parents.
The days that followed were dark, filled with adults whispering about the drunk driver who killed them and debating what to do with me.
The words "foster care" floated around the house. That idea terrified me. I thought I was going to be sent away forever.
But Grandpa saved me.
I thought I was going
to be sent away forever.
Sixty-five years old, tired, already dealing with a bad back and knees, he strode into the living room where all the adults were whispering about my fate and slammed his hand down on the coffee table.
"She's coming with me. End of story."
Grandpa became my whole world from that minute on.
"She's coming with me.
End of story."
Grandpa gave me his big bedroom and took the smaller one for himself. He learned how to braid my hair from YouTube, packed my lunch every day, and attended every school play and parent-teacher meeting.
He was my hero and my inspiration.
"Grandpa, when I grow up, I want to be a social worker so I can save children the same way you saved me," I told him when I was ten years old.
He was my hero.
He hugged me so tight I thought my ribs would crack.
"You can be anything you want, kiddo. Absolutely anything."
But the truth was, we never had much.
No family trips, no takeout, and none of those "just because" gifts other kids seemed to get. As I grew up, I noticed an unsettling pattern emerge in my life with Grandpa.
I noticed an unsettling pattern emerge in my life with Grandpa.
"Grandpa, can I get a new outfit?" I'd ask. "All the kids at school are wearing these branded jeans, and I want a pair."
"We can't afford that, kiddo."
That was his answer to every request for anything extra. I hated that sentence more than anything else in the entire world.
I grew angry at him for always saying NO.
I hated that sentence more than anything else in the entire world.
While the other girls wore trendy, name-brand clothes, I wore hand-me-downs.
My friends all had new phones, but mine was an ancient brick that barely held a charge.
It was an awful, selfish anger, the kind that made me cry hot tears into my pillow at night, hating myself for hating him, but still unable to stop the resentment.
He told me I could be anything I wanted, but that promise started to feel like a lie.
Then Grandpa got sick, and the anger was replaced by a deep, sickening fear.
Grandpa got sick, and the anger was replaced by a deep, sickening fear.
The man who had carried my whole world on his shoulders suddenly couldn't walk up the stairs without gasping for air.
We couldn't afford a nurse or caregiver (of course, we couldn't, we couldn't afford anything), so I took care of him alone.
"I'll be okay, kiddo. It's just a cold. I'll be up and kicking next week. You just focus on your final exams."
Liar, I thought.
We couldn't afford a nurse or caregiver, so I took care of him alone.
"It's not a cold, Grandpa. You need to take it easy. Please, let me help."
I juggled my final semester of high school with helping him get to the bathroom, feeding him spoonfuls of soup, and making sure he took his mountain of medicine.
Every time I looked at his face, thinner and paler each morning, I felt the panic rise in my chest. What would become of us both?
One evening, I was helping him back into bed when he said something that disturbed me.
He said something that disturbed me.
He was shaking from the exertion of the short walk to the bathroom. As he settled down, his eyes fixed on me with an intensity I hadn't seen before.
"Lila, I need to tell you something."
"Later, Grandpa. You're exhausted, and you need to rest."
But we never got a "later."
"I need to tell you something."
When he finally died in his sleep, my world stopped.
I had just graduated from high school, and instead of feeling excited or hopeful, I found myself stuck in a terrifying liminal space that felt like drowning.
I stopped eating properly.
I stopped sleeping.
Then the bills started arriving — water, electricity, property tax, everything.
Then the bills started arriving.
I didn't know what to do with them.
Grandpa had left me the house, but how would I afford to keep it? I'd have to get a job immediately, or maybe try to sell the house just to buy myself a few months of sheer survival before figuring out my next move.
Then, two weeks after the funeral, I got a call from an unknown number.
Two weeks after the funeral, I got a call from an unknown number.
A woman's voice came through the speaker. "My name is Ms. Reynolds. I'm from the bank, and I'm calling regarding your late grandfather."
A bank. Those words I'd hated so much, "we can't afford that," came rushing back, but with a terrible new twist: he was too proud to ask for help, and now I would be held responsible for some massive, unsettled debt.
The woman's next words were so unexpected, I almost dropped my phone.
"I'm calling regarding your late grandfather."
"Your grandfather wasn't who you think he was. We need to talk."
"What do you mean, he wasn't who I think he was? Was he in trouble? Did he owe someone money?"
"We can't discuss the details over the phone. Can you make it this afternoon?"
"Yes, I'll be there."
"Your grandfather wasn't who you think he was."
When I arrived at the bank, Ms. Reynolds was waiting for me.
She led me into a small, sterile office.
"Thank you for coming in, Lila," Ms. Reynolds said, folding her hands neatly on the desk. "I know this is a difficult time for you."
"Just tell me how much he owed," I blurted out. "I'll figure out a payment plan, I promise."
When I arrived at the bank, Ms. Reynolds was waiting for me.
Ms. Reynolds blinked. "He didn't owe anything, dear. Quite the contrary. Your grandfather was one of the most dedicated savers I've ever had the pleasure of working with."
"I don't understand. We never had money. We struggled to pay the heating bill."
She leaned forward, and what she told me next made me realize Grandpa had been lying to me for my whole life.
Grandpa had been lying to me for my whole life.
"Lila, your grandfather came in here 18 years ago and set up a very specific, restricted education trust in your name. He made deposits into that account every month."
The truth hit me like a train.
Grandpa hadn't been poor; he had been intentionally, methodically, frugal. Every time he said, "We can't afford that, kiddo," he was really saying, "I can't afford that right now because I'm building you a dream."
Then Ms. Reynolds held out an envelope to me.
Ms. Reynolds held out an envelope to me.
"He insisted I give you this letter when you came in. It was written several months ago."
I picked up the envelope. My fingers trembled as I unfolded the single sheet of paper inside.
My dearest Lila,
If you are reading this, it means I can't walk you to campus myself, and that breaks my old heart. I'm so sorry, kiddo.
"He insisted I give you this letter."
I know I said "no" a lot, didn't I? I hated doing that, but I had to make sure you got to live your dream of saving all those children, just like you told me you wanted to.
This house is yours, the bills are paid for a while, and the trust is more than enough for your tuition, books, and a nice, new phone, too!
I'm so proud of you, my girl. I'm still with you, you know. Always.
All my love, Grandpa.
I had to make sure you got to live your dream.
I broke down right there in the office.
When I finally lifted my head, my eyes were swollen, but for the first time since Grandpa died, I didn't feel like I was drowning.
"How much is in the trust?" I asked Ms. Reynolds.
She tapped a few keys on her computer.
I broke down right there in the office.
"Lila, he made sure you are completely taken care of. Full tuition, room, board, and a generous allowance for four years at any state university."
I spent the next week researching schools, and I applied to the best social work program in the state.
I was accepted two days later.
That same evening, I went out onto the porch, looked up at the stars, and whispered the vow I had made to him the moment I read his note.
I whispered the vow I had made to him the moment I read his note.
"I'm going, Grandpa." I didn't even try to wipe away the tears that slid down my face. "I'm going to save them all, just like you saved me. You were my hero right up until the end. You got me there. You truly did."
