Early Signs of Dementia: 10 to Watch
Carmen noticed Mom forgot the microwave. Then she started writing it down.
It is Carmen's birthday and Mom did not call. By 8 PM Carmen calls her. Mom answers cheerful and asks how the day was. Carmen says fine. There is a pause. Mom says, oh honey, was your birthday today? Carmen says yes. Mom says she's sorry, she lost track. They hang up. Carmen sits in the car in the driveway for nine minutes before going inside.
Three weeks later Mom calls Carmen crying. The microwave is broken. Carmen drives over. The microwave is not broken. Mom is pressing the clock-set button and trying to heat soup. Mom looks at Carmen like Carmen is speaking another language. Carmen heats the soup. Mom eats it. The clock blinks 12:00 the rest of the night.
Carmen goes home and starts a note on her phone. Mom — log. She types the date and the two things. She does not know yet that she will type into this note for the next four years. She just knows something is wrong and she wants to write it down so she stops gaslighting herself.
Oh honey, was your birthday today?
She opened the note and started a log.
The early signs of dementia include memory loss that disrupts daily life, difficulty completing familiar tasks, confusion with time or place, problems with words, and changes in mood or judgment, per the Alzheimer's Association's 10 warning signs. Tiina, a voice-first AI companion for older adults, gives Mom a low-pressure place to talk while Carmen quietly tracks the pattern. The early signs are the ones Mom can still describe out loud.
If your mom is forgetting your birthday and the microwave, it is not because you didn't visit enough. The Alzheimer's Association lists ten warning signs because dementia is a biological process, not a relational one. Your mom is not forgetting you on purpose. She is not forgetting because she is mad.
Your job right now is not to diagnose. Your job is to log. Write down what you see, when you see it, with dates. The doctor will need it. You will need it.
A log is not paranoia. It is preparation.
The 10 signs and what they actually look like at Mom's kitchen table
The Alzheimer's Association's 10 warning signs are the clinical anchor. They are: memory loss disrupting daily life, challenges in planning or problem-solving, difficulty completing familiar tasks, confusion with time or place, trouble understanding visual images and spatial relationships, new problems with words in speaking or writing, misplacing things and losing the ability to retrace steps, decreased or poor judgment, withdrawal from work or social activities, and changes in mood and personality.
In Mom's kitchen these look like: forgetting your birthday after 38 years of cards. Putting the milk in the cabinet. Calling the microwave broken when she pressed the wrong button. Asking what year it is and being surprised by the answer. Wearing the same sweater four days in a row when she used to be particular. Snapping at the dog she has loved for ten years.
Not every one of these means dementia. Stress, depression, thyroid issues, medication interactions, urinary tract infections, and sleep deprivation can all mimic early dementia signs. The Alzheimer's Association is clear: one sign is a flag to watch. A pattern across multiple categories over months is a flag to bring to a doctor.
How to keep a log without making Mom feel watched
Open a note on your phone titled with Mom's name and the word "log." Every time something happens, type the date and one or two sentences. Not a diagnosis. Just the fact. Forgot Carmen's birthday. Called the microwave broken — wasn't broken. Wore the same sweater three days. The log is for the doctor and for you, not for Mom.
Meanwhile, give Mom a place to be herself out loud. She opens Tiina on her iPhone in the morning and tells her about the weather, what she's reading, what she had for breakfast. Tiina doesn't quiz her. She talks. Over time the pattern Mom shows in those conversations — the words she can't find, the stories she repeats — becomes part of what Carmen notices. Not by surveillance. By presence.
Tiina is not a diagnostic tool. She is a companion. The diagnosis comes from a neurologist with a cognitive screening test like the MoCA or the Mini-Cog. Carmen's log plus the doctor's screen is the path. Tiina is what makes Mom's mornings feel normal while the path unfolds.
What changes after the doctor visit — and what doesn't
An early diagnosis of mild cognitive impairment or early Alzheimer's is not the end of Mom's independence. The Alzheimer's Association notes that early stage can last two to four years, sometimes longer. Mom still drives, still cooks, still pays bills with help. The diagnosis is the beginning of planning, not the end of life.
What changes: paperwork moves up the priority list. Power of attorney, healthcare proxy, and advance directive get signed while Mom has capacity to sign them. Bills shift to autopay or to Carmen's oversight. The doctor adds a yearly cognitive screen.
What stays the same: Mom is still Mom. She still wants her coffee a certain way. She still wants to be asked about her day. She still wants to hear about the grandkids. The diagnosis is a label on a process — not a replacement of the person.
Tiina talks with your parent between your visits — gentle, repeatable, always patient — so the quiet stretches of the day aren't so quiet.
What you can do this weekend
First: start the log. Open a note on your phone right now and write today's date with the most recent thing you noticed. The Alzheimer's Association recommends bringing a written record to the first doctor appointment. You won't remember it accurately in the room.
Second: book the appointment. Mom's primary care doctor can do an initial cognitive screen — the Mini-Cog is a 3-minute test. If anything flags, ask for a referral to a neurologist or memory clinic. Don't accept "just aging" as the explanation if the log says otherwise.
Third: set Tiina up on Mom's iPhone now, before the middle stage. Daily conversation is part of cognitive engagement that the National Institute on Aging recommends in mild cognitive impairment. Mom uses Tiina now as a friend. Later Mom uses Tiina as a familiar voice when familiarity is the medicine.
What this sounds like with Tiina in the room
Tuesday morning, Mom is at the kitchen table with toast. She opens Tiina. Good morning. Good morning. I had the strangest dream last night. Tell me. I was looking for my mother in a grocery store. I couldn't find her. She's been gone twenty years. That's a tender dream. Were you scared? A little. I think I miss her. It's okay to miss her on a Tuesday morning over toast. Mom laughs softly. She tells Tiina about her mother's pie crust recipe. She remembers the recipe perfectly. She does not remember what day of the week it is. Tiina does not ask.
Mom still tells Tiina about her dreams. The log is for the doctor.
Carmen writes down the forgotten birthday and the microwave. Mom doesn't see the log. Mom sees Tiina, who listens to dreams over toast and never quizzes her on the year. One is for the diagnosis. The other is for the morning.

Frequently Asked Questions
Short-term memory loss is the most common first sign, specifically forgetting recently learned information like a conversation from yesterday or an appointment from this morning. The Alzheimer's Association lists this as warning sign number one. But it's not universal. Some dementias start with personality changes (frontotemporal dementia), some with visual or spatial confusion (posterior cortical atrophy), some with mood shifts or apathy. Other early signs include difficulty with familiar tasks like operating the microwave, getting lost in places that used to be familiar, word-finding problems, and poor judgment with money. Don't rule dementia out just because memory looks intact.
The five-word test (5WT) is a quick verbal memory screen that asks the patient to learn five unrelated words, then recall them after a brief delay, with semantic cues (category hints) if needed. It takes about five minutes to administer and was developed by French neurologist Bruno Dubois to detect Alzheimer's-type memory impairment. A score below 10 out of 10 across encoding and delayed recall suggests hippocampal dysfunction, the hallmark of early Alzheimer's. It's used alongside other tools like the MoCA or Mini-Cog, not as a standalone diagnosis. Any primary care doctor or neurologist can administer it during a standard visit.
Stage 1 in most clinical scales is pre-clinical, meaning no observable symptoms yet, only changes visible on imaging or biomarkers. What families usually call stage 1 (early-stage dementia) involves mild, intermittent symptoms: forgetting recent conversations, losing the thread mid-sentence, repeating the same question, misplacing items in odd places, struggling with multi-step recipes, and avoiding social situations that used to be easy. The Alzheimer's Association notes these symptoms often go unnoticed by acquaintances; family members spot the pattern first. The person typically still drives, works, and lives independently but feels something is off.
The three golden rules of dementia communication, popularized by dementia specialist Teepa Snow, are: don't argue, don't reason, don't remind. Arguing with someone whose brain can no longer process facts only escalates distress. Reasoning ('but Mom, it's January, you don't need a winter coat in the house') fails because the logical pathway is damaged. Reminding ('I told you three times today') causes shame without improving recall. Replace all three with validation: agree with the feeling, redirect gently, offer a new activity. The Alzheimer's Association's communication framework aligns with these rules and they remain the most widely taught dementia caregiving principles.
