Consequences of Alzheimer’s and Dementia Have Significant Legal and Financial Impact

Most people hope they will never face memory problems as they age. Yet conditions like Alzheimer's disease and other forms of dementia become more common the older you get, and longer lifespans mean more of us will encounter them. What happens if you or a loved one starts to experience memory decline?

Have you put a plan in place in case memory loss affects you? Maybe you assume it will never happen to you. It's hard to pin down exactly how many people begin to show signs of decline, but the scope is significant. The World Health Organization estimates 57 million people worldwide were living with dementia in 2021, a number projected to nearly triple to 139 million by 2050.

If you haven’t prepared for the future costs and burdens of aging, the consequences can be overwhelming. Without a clear plan for long‑term care, families often find themselves scrambling to understand complex medical, financial, and legal issues at the very moment they’re trying to support a loved one in decline. In some cases, people must turn to an elder‑care attorney to sort out emergency decisions about care, housing, powers of attorney, or asset protection—steps that are far easier and far less stressful when addressed early rather than in crisis.

People Often Ignore Early Signs

Many people brush off the first signs of memory loss. You or a loved one may have trouble focusing or absorbing new information, struggle to make decisions, find complex tasks harder to manage, or lose motivation. Others notice changes in sleep patterns, shifts in behavior, or difficulty keeping up with daily routines.

It's common to blame these changes on stress at home or work. Early-onset dementia, which appears before age 65, most often shows up between ages 45 and 64, according to Kunal Parulekar, M.D., a neurologist at Hackensack Meridian Health. However, many people don't seek a doctor's opinion until family members notice the problem too. Memory changes can also show up in younger people, though less commonly.

Memory issues can be an early warning sign of dementia. Short-term memory problems tend to be subtle at first, such as forgetting where you set something down or walking into a room and forgetting why you're there.

Dementia is Symptom

Someone with memory decline can often recall events from decades ago clearly, yet forget what they had for breakfast. Richard J. Caselli, M.D., a neurologist at the Mayo Clinic in Scottsdale, Arizona, has explained that Alzheimer's disease is the most common cause of dementia, but the two terms aren't interchangeable. As Dr. Caselli put it, "dementia is not memory loss alone but the disabling impairment of multiple cognitive functions."

When we see somebody with early-onset dementia, say at age 45 or so, we have to be concerned about a genetic cause known as a dominantly inherited mutation, or gene change. Just one copy of a dominantly inherited gene change from either parent will cause early-onset Alzheimer's.

Alzheimer's disease is one specific illness that causes dementia. Other conditions do too, including dementia with Lewy bodies, frontotemporal lobar degeneration, and vascular dementia caused by reduced blood flow to the brain. In younger people, a genetic cause is also possible.

When someone develops early-onset dementia around age 45, doctors have to consider a dominantly inherited gene change as a possible cause. Inheriting just one copy of this gene change from either parent can cause early-onset Alzheimer's disease.

According to the Alzheimer's Association's 2026 Alzheimer's Disease Facts and Figures report, an estimated 7.4 million Americans age 65 and older were living with Alzheimer's disease in 2026. Perhaps you think your family will be able to "handle it." Chances are no. The fact is long-term care happens to many of us as we age. Caregiving is hard on family members, and paid care drains assets. Yet, what plans do you have for the legal and financial consequences of cognitive impairment?

How an Elder Law Attorney Can Help

If a loved one develops dementia and has no Long-Term Care Insurance in place, the legal and financial side of their care often falls entirely on family members with no roadmap to follow. An elder law attorney fills that gap. Unlike a general estate lawyer, an elder law attorney focuses specifically on the legal challenges older adults face, including planning for extended care, guardianship proceedings, and navigating public benefit programs like Medicaid.

• Putting decision-making authority in place. If your loved one can still understand and sign legal documents, an elder law attorney can prepare a durable power of attorney and a health care proxy, naming someone to handle finances and medical decisions once your loved one can no longer do so. Waiting too long carries real risk: once dementia progresses far enough, a person may no longer be considered legally competent to sign these documents, and the family is left with no choice but to pursue guardianship.
• Guardianship when there's no plan in place. Without a durable power of attorney already signed, a family often has to petition a court for guardianship or conservatorship to gain legal authority over a loved one's care and finances. Guardianship is consistently described as slower, more expensive, and more public than a power of attorney arranged in advance, since it requires a medical evaluation, a court hearing, and ongoing court oversight. An elder law attorney can guide a family through that process when it becomes necessary.
• Qualifying for Medicaid without losing everything. Without Long-Term Care Insurance, Medicaid often becomes the only realistic way to pay for nursing home or extended care, since Medicare generally doesn't cover long-term custodial care. Medicaid has strict income and asset limits, and most states also enforce a 60-month, or five-year, "look-back" period on financial transactions: any assets given away or sold for less than fair value during that window can trigger a penalty period during which Medicaid won't pay for care.

NOTE: If you or a loved one has a Partnership Long-Term Care Insurance policy and you exhaust benefits you are able to shelter part of yoru estate and still qualify for Medicaid.

An elder law attorney can help a family use legal tools, such as Medicaid Asset Protection Trusts or a Qualified Income Trust, to structure a loved one's finances and qualify for benefits while preserving as much of the family's resources as the law allows.

To find a qualified elder law attorney, use specialized professional directories like the National Academy of Elder Law Attorneys (NAELA) or search for Certified Elder Law Attorneys through the National Elder Law Foundation (NELF). You can also get local referrals from your state bar association or local aging programs, or through search sites like ConsultantLM's lawyer network and search for elder law.

Get Documents in Order. Consider Cost of Long-Term Care

It is always best to plan well in advance when you have the most options. Usually, this means before your retirement. These are three areas many experts suggest you consider:

1. Long-Term Care Insurance – These affordable policies will pay for quality care at home or in a facility. Caution: you must health qualify to get a plan. This means you can't wait until you have dementia to get a policy. It is best to obtain coverage in your 40s or 50s, but you still can get coverage older if you have good health – but premiums can be higher.

2. Advance Directives for Health – These documents will communicate your healthcare wishes when you can no longer speak for yourself.

3. Advance Directives for Finances – These documents will communicate your estate plans.

If you, or a loved one, is in the early stage of dementia, you will have time to put some advance directives in place. Having advance directives, like a power of attorney and living wills, is vital to ensure that your wishes and decisions are honored if you become incapable of making them yourself. 

These documents provide information about your wishes and grant permission to a trusted family member, friend, or professional to make decisions on your behalf. This ensures that important life decisions and financial matters are taken care of if you can no longer do so yourself.

Planning for the cost of long-term health care must also be done in advance. If you have savings, be sure to act before you retire to safeguard your retirement funds and reduce the burdens that come with extended care.

Long-Term Care Insurance, including partnership policies, can help safeguard your 401(k) and other savings while providing guaranteed tax-free funds to pay for quality care in the desired setting.

Why You Need a Plan Before Symptoms Start

No matter your age or the underlying cause, the consequences of dementia become a crisis when you haven't made decisions before symptoms appear. Too many people put off planning for aging, whether the concern is dementia or any other long-term health need.

You might assume your family will simply "handle it." In most cases, they can't, at least not without real cost. Long-term care becomes a reality for a majority of us as we age: the U.S. Department of Health and Human Services estimates 56 percent of Americans turning 65 will need long-term care, meaning ongoing help with two or more daily living activities or supervision due to cognitive impairment. Caregiving takes a serious toll on family members, and paying for care out of pocket drains savings fast. So what plans have you made for the legal and financial consequences of cognitive impairment?

When to Act

There are several options for Long-Term Care Insurance if you have relatively good health to qualify for coverage. 

• Types Of Long-Term Care Insurance Policies - Which Is Best For You

Seek the help of a Long-Term Care Insurance specialist to assist you. Generally, specialists will work with multiple top insurance companies to help find you the best coverage at the lowest cost based on your age, health, and other factors. They will be able to provide you with accurate quotes from all the available companies.

The cost of long-term care varies depending on where you live. This information will be necessary for planning.

The time for planning is before you get older and experience health issues. Important documents should be done without delay. According to LTC News research, most people get Long-Term Care Insurance between teh ages of 47 and 67. 

Taking action does not mean you think you will have a problem as you age. It does mean that you understand the realities of aging and love your family enough to plan to avoid a crisis later.

Planning Today Protects Your Tomorrow

Aging is not a hypothetical future—it’s a certainty. Memory loss, cognitive decline, and long‑term care needs are not rare events but common realities that millions of families face every year. As your document makes clear, “the fact is long-term care happens to many of us as we age. Caregiving is hard on family members, and paid care drains assets.” When you wait, you lose options. When you plan early, you gain control.

The most important truth is this: you cannot rely on hope, denial, or good intentions to carry you through a crisis. Without Long‑Term Care Insurance, without advance directives, without legal authority in place, families are left navigating medical decisions, financial strain, and legal barriers at the exact moment they are least prepared to handle them. An elder law attorney can help—but their role is far more effective when engaged before a crisis, not after one.

Taking action now is an act of love. It protects your savings, shields your family from avoidable stress, and ensures your wishes are honored. Whether that means purchasing Long‑Term Care Insurance, drafting essential documents, or consulting a qualified elder law attorney, the steps you take today will shape the quality of your care tomorrow.

Frequently Asked Questions

What is the difference between dementia and Alzheimer’s disease?

Dementia is a general term describing a disabling decline in multiple cognitive functions that interferes with daily life. Alzheimer’s disease is a specific disease and the most common cause of dementia. Other causes include Lewy body dementia, frontotemporal dementia and vascular dementia.

What are some early warning signs of dementia?

Early signs can include difficulty concentrating, learning new information, making decisions or completing complex tasks. Changes in motivation, behavior, sleep patterns and the ability to manage normal daily routines may also occur. Short-term memory problems can initially be subtle.

Why is it important to plan before cognitive decline occurs?

Dementia can eventually affect a person's ability to make medical, financial and legal decisions. Planning early allows you to establish who can act on your behalf, document your healthcare wishes and prepare financially for possible long-term care. Waiting until a crisis can leave families scrambling to make important decisions.

What legal documents should families consider?

Important documents can include a durable power of attorney for finances, a durable power of attorney for health care, a living will, a will and, depending on the circumstances, a living trust. These documents can establish your wishes and identify people who can make decisions for you if you become unable to do so.

What happens if someone develops dementia without a power of attorney?

If the person no longer has the legal capacity to execute a power of attorney, family members may need to seek guardianship or conservatorship through the courts. This can involve medical evaluations, court proceedings and ongoing oversight, making advance planning much easier for families.

How can an elder law attorney help a family dealing with dementia?

An elder law attorney can help establish decision-making authority, prepare appropriate legal documents, guide families through guardianship when necessary and assist with Medicaid and other long-term care planning issues. Their assistance can be especially valuable before a crisis develops.

Does Medicare pay for long-term care caused by dementia?

Medicare generally does not pay for ongoing custodial long-term care. Without Long-Term Care Insurance or sufficient personal resources, some people eventually rely on Medicaid, which has income and asset eligibility requirements.

Can you buy Long-Term Care Insurance after being diagnosed with dementia?

Generally, no. Long-Term Care Insurance requires medical underwriting, so coverage needs to be purchased while you are still healthy enough to qualify. Waiting until significant cognitive impairment or dementia has developed means it is typically too late to obtain coverage.

How can Long-Term Care Insurance help with dementia-related care?

Long-Term Care Insurance can provide benefits for qualified long-term care services and help protect retirement income and assets from the cost of extended care. Coverage should be obtained well before care is needed because applicants must meet the insurance company's health requirements.
