Estate Planning Data & Research → Married Couples Where a Spouse Has Memory Trouble

1,653,657 married couples with at least one spouse 65 or older include a husband or wife with serious difficulty concentrating, remembering or making decisions (margin of error ±24,360), according to our analysis of the Census Bureau’s 2024 American Community Survey microdata. That’s 89 of every 1,000 older married couples who head their own household, or about 1 in 11.

In 155,541 of those couples, both spouses report the difficulty. In the other 1,498,116, one spouse is now the “well spouse,” and that’s where an estate plan gets tested. Married couples often own the house, the bank accounts and the brokerage account jointly, and rely on each other as agent under a power of attorney and as heir under a will. When one spouse can no longer make decisions, the other often can’t sell or refinance the house, move money out of the other spouse’s IRA, or change the plan without a document signed earlier, or a court. This page shows where these couples live and what to put in place while both spouses can still sign.

Are you married and starting to worry about a spouse’s memory? A will or trust written for this situation, signed while you both still can, is how you keep control instead of a court. See whether a trust or a will fits your situation.

Key findings

• 1,653,657 couples, 89.0 per 1,000 married couples with a spouse 65+ (±1.3). Out of 18,575,550 married-couple households where the householder or spouse is 65+, 8.9% include a spouse with a cognitive difficulty.
• Usually it’s one spouse. In 90.6% of these couples (1,498,116), only one spouse has the difficulty; in 9.4% (155,541), both do.
• The well spouse is often old and has health problems too. Where only one spouse is affected, the other spouse is 75 or older in 43.3% of couples and reports a disability of their own in 37.0%.
• The affected spouse often needs daily help. In 65.9% of these couples, the affected spouse (or one of them) has difficulty doing errands alone, and in 38.6% difficulty bathing or dressing. 15.2% include an affected spouse 85 or older.
• Most own their home. 83.4% of these couples own their home (with or without a mortgage), compared with 90.6% of all older married couples. The median home value among owners is $300,000, versus $375,000 for all older married-couple owners.
• Highest rate: New Mexico (149.0 per 1,000), Mississippi (130.8), Alabama (121.8), West Virginia (116.1), Arkansas (113.0) and Kentucky (107.8). Lowest: Delaware (57.5), Rhode Island (64.6), New Hampshire and Vermont (both 68.6), Iowa (70.3) and New Jersey (73.3). Delaware, Rhode Island, Vermont and the other smallest states have wider margins of error.
• Most couples: California (170,224), Florida (135,326), Texas (130,389), New York (89,692) and Pennsylvania (62,077).
• Of all 4,420,278 people 65+ with a cognitive difficulty who live in households, 36.9% live with a spouse, 29.6% live alone and 33.5% live with other relatives or others. Another 985,185 people 65+ with the difficulty live in group quarters such as nursing homes.

Married couples where a spouse has a cognitive difficulty, by state, 2024

Source: Family Estate Guide analysis of the U.S. Census Bureau’s American Community Survey 2024 1-year Public Use Microdata Sample. Couples are married-couple households in which the householder or spouse is 65+; “cognitive difficulty” means at least one spouse reported serious difficulty concentrating, remembering or making decisions. Rate is per 1,000 such couples. Margins of error are at the 90% confidence level, from the 80 replicate weights. Reliability is based on the coefficient of variation; treat “fair” estimates (CV 15-30%) as rough. States are ranked by rate.

What the numbers mean

The survey question isn’t a dementia diagnosis. It asks whether, because of a physical, mental or emotional condition, a person has serious difficulty concentrating, remembering or making decisions. It captures Alzheimer’s disease and other dementias, but also stroke, Parkinson’s disease, serious depression and other conditions. Some people answer for their spouse. What the measure does say is that in about 1 in 11 older married households, at least one spouse already has trouble with the kind of thinking that legal documents and money decisions require.

The highest rates are in New Mexico and several Southern and Appalachian states. The ranking isn’t simply about which states have the most retirees: Florida, with a large older population, is close to the national rate (88.1 per 1,000), and the rate measures how common the difficulty is among older couples, not how many couples a state has. In the largest states the counts are big enough that the rate is precise; in the smallest, use the reliability column.

Why a spouse’s memory trouble is an estate planning problem

Marriage doesn’t give you legal authority over your spouse’s property. Many couples assume that being married lets one spouse handle everything. It doesn’t. You can usually use a joint bank account. But in most states, selling, refinancing or borrowing against a home the two of you own together takes both signatures, and an IRA, 401(k), annuity or account in your spouse’s name alone belongs to your spouse. Without a durable power of attorney signed while your spouse still had capacity, the usual route is a court guardianship or conservatorship, which takes time, costs money, and puts a judge in charge of approving what you do.

A power of attorney only works if it was signed in time. A person must understand what they’re signing. Once memory trouble is advanced, it may be too late, and a document signed in a borderline period is easier for relatives to challenge later. The safest time is now, while both spouses can clearly sign.

Many wills leave everything to a spouse who may not be able to manage it. The most common married-couple plan, “everything to my spouse, then to the kids,” can backfire. If the well spouse dies first, the inheritance goes outright to the spouse who can’t manage it, often forcing a guardianship to handle it. It can also push the surviving spouse over Medicaid’s asset limit right when nursing home care may be needed.

The well spouse’s own plan matters as much as the affected spouse’s. The well spouse is the one who can still sign and change their will, trust and beneficiary forms. In 43.3% of these couples the well spouse is 75 or older, so the risk of the well spouse dying or becoming ill first is real.

How Medicaid treats a married couple

Long-term nursing home care is expensive, and many families end up applying for Medicaid to pay for it. Federal spousal impoverishment rules (42 U.S. Code 1396r-5) set out how a married couple’s money is counted:

• All resources count, no matter whose name they’re in. When the spouse needing care applies, Medicaid looks at the assets of both spouses, in either name or both, regardless of state community property or marital property laws.
• The spouse at home keeps a protected amount. For 2026, the federal community spouse resource allowance is at least $32,532 and at most $162,660, depending on the state and the couple’s assets, according to the Centers for Medicare & Medicaid Services. The home, one car and some other items generally don’t count.
• The spouse at home keeps some income. The minimum monthly maintenance needs allowance is $2,705.00 in most states from July 1, 2026 ($3,381.25 in Alaska and $3,111.25 in Hawaii), up to a maximum of $4,066.50 in 2026. If the at-home spouse’s own income is lower, part of the other spouse’s income can be set aside for them.
• Transfers between spouses aren’t penalized. Gifts to your spouse don’t trigger the 60-month look-back penalty (42 U.S. Code 1396p(c)(2)(B)). After eligibility, the at-home spouse’s own assets are no longer counted for the spouse in care.
• The home is protected while a spouse lives there. The 2026 home equity limits ($752,000 to $1,130,000, depending on the state) don’t apply when a spouse lives in the home, and Medicaid can’t recover from the estate until after the surviving spouse dies (42 U.S. Code 1396p(b)(2)). See Medicaid estate recovery by state and Medicaid home equity limits by state.

One detail matters for the well spouse’s will. Under federal law, a trust a spouse creates during life with the couple’s money is generally counted for Medicaid, but the rule applies to trusts set up “other than by will” (42 U.S. Code 1396p(d)(2)(A)). That’s why elder law attorneys often put a trust for the affected spouse inside the well spouse’s will, rather than leaving the money to the affected spouse outright. In some states, a surviving spouse’s right to claim an elective share against the will can complicate this, so it needs state-specific advice. See the surviving spouse’s elective share.

What to do if your spouse is starting to have memory trouble

1. See a doctor and get it documented. An evaluation helps with care, and a doctor’s note that your spouse has capacity now helps if a document is later questioned.
2. Both of you sign durable financial powers of attorney naming each other, with an adult child or other trusted person as backup. Make sure the document lets the agent deal with real estate and retirement accounts, and, if your state allows, make gifts or Medicaid planning transfers.
3. Both of you sign health care powers of attorney, living wills and HIPAA authorizations.
4. Review how the house and accounts are titled. A revocable living trust with a successor trustee lets the trustee manage the assets without a court, as long as the assets are retitled into the trust while your spouse can still sign.
5. The well spouse updates their own will or trust so nothing goes outright to the affected spouse if the well spouse dies first. A trust for the spouse, with a trustee, is the usual fix.
6. Check beneficiary forms on life insurance, IRAs and 401(k)s. Naming the affected spouse directly can have the same problem as an outright inheritance.
7. For Social Security and VA benefits, apply to be the representative payee or VA fiduciary. Those agencies don’t accept a power of attorney.
8. Talk to an elder law attorney before nursing home care is needed, about your state’s spousal allowances and how to protect the at-home spouse.

An example

Frank, 79, and Ruth, 77, own their $300,000 house jointly and have $220,000 in savings, mostly in Frank’s IRA. Ruth was diagnosed with Alzheimer’s disease last year. They have wills from 1998 that leave everything to each other, and no powers of attorney. If Frank wants to sell the house to move into assisted living together, he can’t sign for Ruth. If Frank dies first, his IRA and the house pass to Ruth, who can’t manage them, and their daughter would likely need to go to court. If Ruth later needs nursing home care, Medicaid would count the inheritance. Signing powers of attorney now (if Ruth still has capacity), a new will or trust for Frank that holds Ruth’s share in trust, and updated beneficiary forms would solve most of it.

Methodology

We used the Census Bureau’s American Community Survey 2024 1-year Public Use Microdata Sample (PUMS), pulled from the Census Data API on Oct. 25, 2026, for the 50 states and the District of Columbia. A couple is a married-couple household (HHT2 = 1 or 2) with the householder (RELSHIPP = 20) and an opposite-sex or same-sex spouse (RELSHIPP = 21 or 23), where at least one of the two is 65 or older. A couple is counted if at least one spouse has a cognitive difficulty (DREM = 1). Counts use the household weight (WGTP), and margins of error come from the 80 replicate weights using the Census Bureau’s formula. Profile figures use the same records: both spouses with DREM = 1; age and any disability (DIS) of the other spouse; self-care (DDRS) and independent living (DOUT) difficulty of the affected spouse; tenure (TEN = 1 or 2 for owners) and home value (VALP), with weighted medians. Living arrangement figures for all people 65+ with a cognitive difficulty use person weights (PWGTP): with a spouse (householder in a married-couple household, or the householder’s spouse), alone (one-person household) or other; people in group quarters are reported separately. Medicaid figures are from 42 U.S. Code 1396r-5 and 1396p and the Centers for Medicare & Medicaid Services 2026 SSI and spousal impoverishment standards.

What this doesn’t measure. It doesn’t count married couples living in someone else’s home (for example, older parents in an adult child’s house), unmarried partners, or couples where one spouse is already in a nursing home. The cognitive question is self- or proxy-reported, not a diagnosis. Our count of 4,420,278 people 65+ with a cognitive difficulty in households differs from the published table figure on our incapacity gap page because that table covers the civilian noninstitutionalized population, which includes some group quarters. The data doesn’t say whether couples have a will, trust or power of attorney. ACS 2025 1-year data is scheduled for release on Oct. 29, 2026, and we plan to update the table after that.

Frequently asked questions

Can I sign for my spouse if they have dementia?

Not automatically. You can usually use a joint bank account, but selling a jointly owned home or handling accounts in your spouse’s name generally takes a durable power of attorney signed while your spouse had capacity, or a court guardianship or conservatorship.

Is it too late for a power of attorney after a dementia diagnosis?

Not necessarily. A diagnosis doesn’t by itself mean a person lacks capacity. Many people in the early stage can still understand and sign. Act quickly, and ask the attorney whether a doctor’s letter is wise.

Should my will leave everything to my spouse if my spouse has memory loss?

Often not outright. Many attorneys recommend leaving a spouse’s share in a trust with a trustee, which avoids a guardianship. If it’s created in your will and set up correctly, it generally isn’t counted as your spouse’s own money for Medicaid. State rules vary, so have an elder law attorney write it.

How much can a spouse keep if the other spouse goes on Medicaid?

In 2026, the at-home spouse can keep at least $32,532 and up to $162,660 in countable assets depending on the state, plus the home, a car and personal items, and at least $2,705.00 a month in income in most states.

How many married couples have a spouse with memory problems?

In 2024, 1,653,657 married couples with a spouse 65+ included a spouse with serious difficulty concentrating, remembering or making decisions, or 89.0 per 1,000 older married couples.

Is this legal advice?

No. Talk with an estate planning or elder law attorney in your state.
