Your mother has always handled her own checkbook. Lately, though, the same bill gets paid twice. A letter about a lottery she almost won sits on the counter. Most families call this normal aging and move on.
That assumption is where the trouble starts. The signs of decline in aging parents rarely announce themselves. Instead, they show up quietly, in money and in mobility. That happens months or even years before anyone says the word “dementia.”

The guest presenter is Marlon Minera, MD. He is board certified in internal medicine with a subspecialty in geriatrics, and he founded the concierge practice Del Oro Longevity. In this July 2026 session, he walks through five real patient cases with Dennis M. Sandoval, Certified Specialist in Estate Planning, Trust and Probate Law. Watch it to learn which signs of decline in aging parents should prompt a doctor’s visit, and what waiting actually costs a family.
Past sessions are archived in the Sandoval Legacy Group webinar library, and upcoming webinars are free to attend.
What are the early warning signs of decline in aging parents?
The five most common signs of decline in aging parents are memory changes, financial mistakes, loss of mobility, growing frailty, and caregiver exhaustion. Minera identified these as the patterns he sees most often in geriatric practice.
None of them arrive as a crisis. They build.
A parent starts steadying themselves on the furniture to cross a room. Minera calls this “couch surfing,” and it means walking has become work. Routines get dropped. Judgment shifts in small ways that are easy to explain away.
By the time a family sees the fall or the diagnosis, they are seeing the tip of an iceberg. The decline underneath it started much earlier. That earlier stretch is where families still have real choices.
Why do the financial signs of decline in aging parents appear first?
Money management usually slips first because it asks more of the brain than almost any other daily task. It requires memory, judgment, arithmetic, and planning at the same time. So it breaks early.
Minera’s first case was a 75-year-old retired accountant who had worked with numbers for 40 years. In retirement, he began paying his bills twice a month. His family shrugged it off as getting older. It was a yellow light instead.
Two terms are worth defining here. Mild cognitive impairment is a measurable decline in thinking that is not yet dementia, and it does not always progress to it. Dementia is the umbrella term for conditions that cause significant loss of mental ability. About 75% of dementia cases are Alzheimer’s disease, though vascular dementia and Lewy body dementia are also common.
Minera cited research showing that roughly 82% of people with mild cognitive impairment can still manage their own finances. He also cited findings that families lose about $30,000 over roughly four years before anyone notices anything is wrong.
Scammers work in that gap. Minera described an 82-year-old man with vascular dementia. A caller posed as his grandson, and he lost $100,000 in one week. In a second case, a handyman spent six months befriending a man in his early 80s with early Alzheimer’s. He then walked him into a bank for a notarized reverse mortgage worth $240,000. The most severe case Minera cited involved a 79-year-old man who lost $1.2 million over 14 months.
What makes a fall so much more than a fall?
A fall is usually the visible end of a slow physical decline rather than a random accident. Something measurable almost always came first.
That something is frailty. Frailty means a loss of physical reserve: the body no longer has the energy stores to recover from a small setback. A urinary tract infection, mild dehydration, or one new medication can knock a frail person down for good.
Minera’s second case was an 82-year-old man on blood pressure medication who added an over-the-counter sleep aid. He got up at night, felt dizzy, fell, and fractured his hip. He never walked independently again. Because he had no power of attorney in place, his family also scrambled through a legal emergency.
The CDC reports that one in four older adults falls each year. Minera cited NIH findings on what happens next. A single fall carries roughly a 15% chance of a hospital return. Two falls within six months push that risk close to 50%.
Recovery also takes longer than families expect. Rehab typically restores only 30% to 40% of lost function. Getting the rest back often takes about six months of daily effort.
Prevention works better. Minera recommends 30 minutes of activity four or five days a week, plus resistance work with even two-pound dumbbells. Protein matters too: roughly 30 grams per meal, or close to 100 grams a day. That combination slows sarcopenia, the age-related muscle loss that runs about 1% per year.
Who takes care of the caregiver?
The caregiver is the second patient, and most never chose the role. Minera cited research in which 61% of spouses and 51% of adult children said they had no real choice.
The job escalates, too. It begins with errands and bill-paying. Eventually it becomes bathing, feeding, and transferring someone in and out of bed. That work is designed for a licensed nurse. Instead, an untrained family member does it in a living room.
Minera described a pattern he sees constantly. One daughter, usually the one who lives closest, becomes the sole caregiver. Two years pass without a break. She starts deciding alone. Out-of-state siblings grow resentful, care quality drops, and money gets spent in ways nobody agreed to.
Respite care means a few scheduled hours off, and it is the first intervention Minera recommends. Adult day programs, community agencies, In-Home Supportive Services (IHSS), and faith communities can all provide it.
The alternative is costly. Paid in-home care runs about $40 an hour. Part-time help at 20 hours a week reaches roughly $50,000 a year. Full-time approaches $100,000. Around-the-clock care lands between $300,000 and $400,000 annually. Those numbers are why the financial signs of decline in aging parents deserve early attention.
When is it too late to sign a power of attorney?
Once a parent no longer has the mental capacity to understand what they are signing, it is too late. No family meeting can undo that.
Under California law, a person needs legal capacity to sign a power of attorney, trust, or will. A power of attorney is a document naming someone to make financial or medical decisions for you. Signed too late, it is invalid. The family’s remaining option is then conservatorship. That is a court process in which a judge appoints a decision-maker, and it costs more and takes far longer.
Minera described families arriving with a brand-new power of attorney. In one, the aunt who signed it had carried an Alzheimer’s diagnosis for five years. That document does not hold.
He raised a second problem as well: estate plans treated as one-and-done. One couple finished their planning in their 60s and never revisited it. By their 80s, the husband had Parkinson’s disease with dementia. Nobody could say when the power of attorney was meant to activate, or what his wishes actually were.
For that reason, Minera now asks to see the trust and the power of attorney. He does this for every patient who cannot speak for themselves. Those documents tell the medical team who decides and what the patient wanted.
What this means for your family
The planning window closes quietly, and it closes on the legal side before it closes on the medical side. Three steps are worth taking now.
Watch for specific changes, not a general feeling. Missed or duplicated bills. New difficulty walking or standing up. Withdrawal from routines and friendships. Any one of these signs of decline in aging parents is reason enough to call a physician.
Lead with an observation, not a verdict. Minera suggests starting with the shared goal of staying at home. Then name what you noticed, without judgment: “I’ve noticed the mail piling up. How can I help?”
Update the legal documents while capacity is not in question. Working years and early retirement are the right time. California’s long-term care Medi-Cal rules also reward planning done well in advance.
The Certified Specialists in Estate Planning, Trust and Probate Law at Sandoval Legacy Group work with families across Riverside, Corona, Newport Beach, Los Angeles, the Temecula Valley, San Diego, and Vista. Advance planning can open access to programs such as IHSS, PACE, and the Assisted Living Waiver. Nearly all of it requires lead time. As Minera put it, you cannot do it in a crisis.
Frequently asked questions
Is forgetfulness a normal part of aging?
Some of it is. Losing your keys or blanking on a name happens at every age, and stress accounts for most of it. The signs of decline in aging parents that matter more involve familiar, complex tasks. A retired bookkeeper who suddenly cannot reconcile a bank statement is showing something different.
What is the difference between mild cognitive impairment and dementia?
Mild cognitive impairment is a measurable decline in thinking that still allows independent living, and it does not always progress. Dementia involves loss significant enough to interfere with daily function. Minera noted that roughly 82% of people with mild cognitive impairment can still manage their own finances. That is exactly why the condition gets missed.
Can you still sign a power of attorney after a dementia diagnosis?
Sometimes, but the diagnosis alone does not decide it. What matters is capacity at the moment of signing. Early-stage patients may still have it, while later-stage patients generally do not. A California elder law attorney should evaluate the situation first. An invalid document leaves conservatorship as the only remaining path.
Does Medicare pay for long-term care at home?
No. Medicare Part B generally covers 80% of approved medical services and leaves 20% to the patient. It also does not pay for custodial care, meaning ongoing help with bathing, dressing, or supervision. Long-term care Medi-Cal, long-term care insurance, IHSS, and private pay are the common funding routes in California. Eligibility for the public programs usually depends on planning done in advance.
How do I start the conversation with a parent who does not want help?
Start with their goal instead of your concern. Most people want to stay in their own home, so frame the discussion around what makes that possible. Minera also suggests reading a book about aging together and discussing the character’s situation. That indirect route often opens a door a direct question closes.
