What to Do After a Dementia Diagnosis: A San Diego Family Plan

A dementia diagnosis can bring shock, grief, fear and, for some families, relief at finally having an answer. Most families leave the doctor’s office with a pamphlet and a dozen questions. If you are wondering what to do after a dementia diagnosis, the good news is that you do not have to do everything at once. A clear plan over the first few months takes care of the most important steps while your loved one can still take part in decisions.

This guide walks San Diego families through what to do after a dementia diagnosis: medical follow-up, legal and financial planning, home and driving safety, the stages of care, and the care options in San Diego County, including small memory care board and care homes.

First, Take a Breath

Dementia usually progresses over years, not weeks. Many people live well for a long time after diagnosis, especially in the early stage. Your first job is not to solve the future. It is to understand the diagnosis, protect your loved one’s wishes, and build a support team.

A simple way to organize the work is a 90-day plan:

• Days 1 to 30: understand the diagnosis and get organized
• Days 15 to 45: legal and financial planning
• Days 30 to 60: safety at home and on the road
• Days 45 to 75: build a support network
• Days 60 to 90: learn about care options and plan for the future

The steps overlap on purpose. The rest of this guide explains each one.

Step 1: Understand the Diagnosis and Medical Next Steps

“Dementia” is an umbrella term. The type matters, because symptoms, progression and treatment differ.

Ask the doctor:

• What type of dementia is this: Alzheimer’s disease, vascular dementia, Lewy body dementia, frontotemporal dementia, or a mix?
• What stage is it, and what changes should we expect over the next year?
• Have treatable causes been ruled out, such as medication side effects, thyroid problems, vitamin B12 deficiency, depression, sleep apnea, or hearing and vision loss?
• Are there medications that may help with symptoms? For early Alzheimer’s, is my loved one a candidate for newer anti-amyloid treatments, and what are the risks?
• Are there clinical trials we should consider? San Diego has active dementia research programs at local universities and health systems.
• Should we see a neurologist, geriatrician or memory clinic for follow-up?

Get organized. Start a care notebook or shared digital file with the diagnosis, medication list, doctors, insurance cards, and questions for the next visit. Bring it to every appointment. Ask the doctor to note in the chart who may receive medical information.

Review medications. Medication mistakes are one of the biggest early dangers for a parent with dementia living alone. Taking too much can cause dizziness, drowsiness and falls, or upset sleep and lead to nighttime wandering. Taking too little can let conditions like diabetes or heart failure get out of control. Ask the pharmacist about blister packs, and consider a locked dispenser or supervised dosing.

Watch for common emergencies. For seniors with dementia, the usual reasons for an ER visit are magnified: falls, dehydration, poor nutrition and urinary tract infections. A sudden jump in confusion is often a sign of infection, not just “the dementia getting worse,” and deserves a call to the doctor.

Step 2: Legal and Financial Planning After a Dementia Diagnosis

This is the most time-sensitive part of what to do after a dementia diagnosis. Legal documents require the person to have capacity to sign, and capacity fades. Do this in the first month or two if you can.

Key documents:

• Durable power of attorney for finances so a trusted person can pay bills, manage accounts and deal with benefits
• Advance health care directive naming a health care agent and recording wishes about treatment
• POLST (Physician Orders for Life-Sustaining Treatment) when appropriate, completed with the doctor
• Will or living trust review, and updated beneficiaries
• HIPAA authorization so doctors can talk with family

Without these documents, families may need to go to court for a conservatorship to make decisions, which is slow, costly and public. If you are legally responsible for a parent with dementia, keeping them safe is also part of that responsibility. Unsafe situations can lead to involvement from Adult Protective Services.

An elder law attorney can prepare documents, explain Medi-Cal planning and help protect a spouse who stays at home.

Money matters:

• Make a list of income, accounts, insurance policies, property and debts.
• Set up automatic bill pay and watch accounts for unusual activity. People with dementia are prime targets for scams.
• Find any long-term care insurance policy and read what it covers.
• Check veterans benefits. Veterans and surviving spouses may qualify for the VA Aid and Attendance pension. See our guide to veterans assisted living.
• Learn the Medi-Cal rules. California reinstated a Medi-Cal asset limit in 2026 of about $130,000 for an individual, with the home generally exempt if the person lives there. Our Medi-Cal eligibility guide explains more.

Step 3: Safety at Home and on the Road

The safety of any senior living alone is a worry. With dementia, almost anything that can happen eventually does: leaving the stove on, getting lost on a walk, opening the door to a stranger, or missing meals for days.

Home safety checklist:

• Remove trip hazards, add lighting and grab bars, and consider a shower chair
• Install stove shutoff devices or remove knobs if cooking becomes unsafe
• Lock up medications, firearms, car keys and cleaning products
• Use door chimes or alarms if wandering starts, and consider a medical ID bracelet or GPS device
• Lower the water heater temperature to prevent burns
• Post a simple list of emergency contacts by the phone

Driving. Many people in early-stage dementia still drive, but driving skills decline. California law requires doctors to report a diagnosis of Alzheimer’s disease and related disorders to the local health department, which passes the report to the DMV. The DMV may then require a reevaluation. Ask the doctor about a driving evaluation, watch for warning signs such as new dents, getting lost or near misses, and plan other ways to get around before the keys have to go.

Living alone. In the early stage, some people can live alone with support: daily check-ins, meal delivery, medication help and a home care aide. Reassess every few months. When your parent is no longer safe alone, it is time for more help.

Step 4: Build a Support Network

Dementia care is a long road. No one should walk it alone.

• Talk with your loved one about how they want to be involved in decisions and what matters most to them.
• Divide family roles. Decide who handles finances, medical appointments, visits and check-ins.
• Connect with local help. Alzheimer’s San Diego offers free care consultation and support groups, and the Southern Caregiver Resource Center serves family caregivers across San Diego County. Our guide to caregiver support in San Diego lists more options.
• Use day programs. Adult day programs give structure and social contact for your loved one and regular breaks for you. See our guide to adult day care for dementia in San Diego.
• Bring in help at home as needed, from a few hours a week of companionship to daily personal care. Learn more about in-home care in San Diego.
• Protect the caregiver. Plan for rest and respite from the start, not after burnout sets in.

Communication tips. As dementia progresses, speak slowly and simply, ask one question at a time, avoid quizzing (“Do you remember…?”), and respond to the feeling behind a statement rather than correcting facts. Patience and reassurance work better than arguing.

Care Planning Through the Stages of Dementia

Every person’s path is different, but care needs usually follow a pattern.

Early stage. Memory lapses, trouble with planning, finances and complex tasks, and sometimes depression or anxiety. Most people live at home with some support. This is the time for legal planning, safety changes, day programs and conversations about future wishes.

Middle stage. Usually the longest stage. Your loved one needs help with daily tasks such as bathing, dressing and medications. Confusion, repeated questions, sundowning, wandering and personality changes may appear. Family caregivers often need in-home help, adult day care, or a move to a residential setting during this stage.

Late stage. The person needs help with nearly everything, including eating, toileting and moving. Many stop walking and speaking much. Care focuses on comfort, dignity and quality of life, and hospice may be appropriate. See our San Diego hospice guide.

Planning ahead for each stage means fewer crisis decisions made from a hospital hallway.

Dementia Care Options in San Diego

When care needs grow beyond what family and home help can safely cover, San Diego families usually consider three residential options. All are licensed by the California Department of Social Services as Residential Care Facilities for the Elderly (RCFEs), and any home that accepts residents with dementia must meet extra training and safety rules.

Assisted living. Larger communities with apartments, dining rooms and activities, often a good fit in early dementia for social seniors. In San Diego, assisted living generally costs about $5,500 to $12,500 per month in 2026, with care fees added as needs grow.

Memory care communities. Secured buildings or wings designed for dementia, with specialized staff and programs. Memory care in San Diego generally costs about $7,500 to $14,000 per month.

Memory care board and care homes. Small, licensed homes in regular neighborhoods caring for about 6 residents, many of them specializing in dementia. These senior care homes offer calm, routine, home cooking and consistent caregivers, typically 1 to 2 for 6 residents during the day. Small dementia board and care homes in San Diego generally cost about $6,000 to $9,500 per month. A private room often adds $1,000 to $2,000 per month over a shared room.

For many people with middle- or late-stage dementia, especially those who are overwhelmed in crowds, no longer walk, or need a lot of hands-on care, a small elder care home is often the best fit and the best value. Many can also keep residents through the end of life with a hospice waiver. Compare all three in our guide to memory care vs. assisted living, and see our pages on memory care facilities in San Diego and board and care homes in San Diego.

How care homes decide what care is needed. Before move-in, every RCFE in California needs a Physician’s Report (form LIC 602A) completed by your loved one’s doctor, which lists diagnoses, including any dementia, and abilities. The home’s administrator or nurse will also meet your loved one to assess needs. Getting the 602A done early saves time if a move happens quickly.

When Is It Time to Move?

There is rarely one perfect moment. Signs that it may be time to look at residential senior care include:

• Your loved one is no longer safe alone, even for a few hours
• Wandering, nighttime waking or sundowning is getting worse
• Falls, weight loss, missed medications or hygiene problems keep happening
• The family caregiver’s health or job is suffering
• Care at home has become more expensive than a care home

Tour a few options well before you need them. Seeing a good home for elderly adults with dementia when there is no crisis makes the eventual decision far easier. Our list of warning signs a parent needs senior care can help.

Frequently Asked Questions About What to Do After a Dementia Diagnosis

What should we do first after a dementia diagnosis?

Learn the type and stage of dementia, ask about treatment options, and start a care notebook with medications, doctors and questions. Then schedule a visit with an elder law attorney to put legal documents in place while your loved one can still sign.

When should legal documents be signed after a dementia diagnosis?

As soon as possible. A durable power of attorney and advance health care directive require the person to understand what they are signing. Waiting can mean the family needs a court conservatorship later.

Does a dementia diagnosis mean my parent has to stop driving?

Not always right away. California doctors must report Alzheimer’s and related disorders to public health, which notifies the DMV, and the DMV may require a reevaluation. Ask the doctor about a driving evaluation and plan alternatives before driving becomes unsafe.

Can a person with dementia keep living alone?

Sometimes in the early stage, with daily check-ins, medication help and in-home support. Safety should be reassessed every few months. Wandering, missed medications, kitchen accidents and falls are signs it is no longer safe.

What is the difference between memory care and a dementia board and care home?

Memory care communities are larger secured buildings or wings designed for dementia. Dementia board and care homes are small licensed homes with about 6 residents and consistent caregivers. Both must meet California’s dementia care rules, but the setting, staffing and cost differ.

How much does dementia care cost in San Diego?

In 2026, memory care communities in San Diego generally cost about $7,500 to $14,000 per month, and small dementia board and care homes about $6,000 to $9,500. Assisted living runs about $5,500 to $12,500. A private room often costs $1,000 to $2,000 more than a shared room.

Does Medicare pay for dementia care?

Medicare covers doctor visits, testing, some medications, short rehab stays and hospice. It does not pay for long-term care in assisted living, memory care or board and care homes. Medi-Cal, VA benefits and long-term care insurance may help, depending on eligibility.

When should we start looking at memory care options?

Start learning early, even if a move is years away. Touring a few homes in the early stage lets your loved one share preferences and keeps the family from making a rushed decision during a crisis.

What is a LIC 602A, and why does it matter?

The LIC 602A is the Physician’s Report that California care homes require before move-in. It lists diagnoses, medications and functional abilities, and it helps the home decide whether it can meet your loved one’s needs. Ask the doctor to complete it early to avoid delays.
