Recent scientific discoveries about the mechanisms of Alzheimer's disease — and promising prospects for medications that can intervene earlier — are offering new hope to millions of families caring for loved ones with the disease. But before discussing treatment, the more important step is learning to recognize the disease early and understanding what you can do to help.
This article explains what Alzheimer's disease is, the initial signs to watch for, and the specific steps that Vietnamese families — both in the United States and those sponsoring parents to come here — can take starting today.
Knowing how to ask for help is not a lack of filial piety — that is smarter care.
What is Alzheimer's Disease Really?
Alzheimer's disease is the most common form of dementia, accounting for approximately 60 to 80 percent of all dementia cases worldwide, according to the Alzheimer's Association. It is a disease of the brain — not "normal forgetfulness that comes with age" — that causes nerve cells to gradually die and cannot be repaired.
Imagine the brain as an enormous telephone network. Alzheimer's disease is like someone silently cutting one wire at a time, starting from the area that manages short-term memory, then spreading to language, thinking, and finally the ability to control the body. This process happens slowly — usually taking many years before the family realizes something is wrong.
According to the National Institute on Aging, the disease typically appears in people over 65 years old, but in a small number of cases it can begin earlier, between ages 40 and 50.
Early Signs — and How to Distinguish Them from "Normal Forgetfulness
Many Vietnamese families overlook the first signs because they think it's normal for elderly parents to forget things. This is an important boundary to understand clearly.
Forgetting someone's name and then remembering it later — that is normal aging. But forgetting an important event that just happened and never remembering it again — that is a concerning sign.
Specifically, pay attention when your loved one:
- Asks the same question repeatedly within minutes, as if they don't remember asking it.
- Gets lost in familiar places — for example, a neighborhood they have lived in for decades.
- Has difficulty finding words while talking, often stopping mid-sentence unable to find the word they want to say.
- Becomes confused about dates, seasons, or doesn't remember where they are.
- Shows distinct changes in personality — someone who was cheerful becomes suspicious, anxious, or withdraws from social activities.
- Leaves objects in unusual places, such as putting a wallet in the refrigerator.
If you notice two or three of these signs appearing consistently, it is time to take your loved one to see a doctor — not to panic, but to get an accurate evaluation.
How Important Is Early Diagnosis?
Early diagnosis allows families to make care plans while the person with the disease can still participate in important decisions — about finances, living arrangements, and medical wishes. In addition, some current medications like lecanemab (brand name Leqembi, FDA approved in 2023) can slow disease progression in early stages, but they are not effective if the disease has already advanced to a severe stage.
Doctors typically use a combination of cognitive tests, blood tests, and sometimes brain imaging (MRI or PET scan) to diagnose the disease. Ask your family doctor for a referral to a neurologist or geriatrician if you have concerns.
The Perspective of Vietnamese Families in America
This is where the story becomes a bit more complicated for Vietnamese communities in America.
Language barriers in diagnosis are a real issue. Standard cognitive tests are typically designed for English speakers and tied to American cultural contexts. An elderly gentleman who came from Saigon to America at age 70 might be evaluated lower than his actual condition if the test does not match his language background. Request a medical interpreter — not just having your children interpret, because medical terminology requires professional expertise — and ask your doctor if there is a Vietnamese version of the cognitive test.
The concept that "family matters should not be discussed outside the home" is also a major barrier. In many Vietnamese families, placing elderly parents in a long-term care facility (nursing home) is seen as abandoning them. This leads to many family caregivers — often women, often daughters or daughters-in-law — caring alone until they are exhausted. This is worthy sacrifice, but it also has limits.
Knowing how to ask for help is not a lack of filial piety. That is smarter care.
What Families Can Do — Practical Steps
Step 1: Don't wait until you're "completely sure" to see a doctor. If you have suspicions, schedule an appointment with your family doctor first. Write down the symptoms you observe — dates, times, specific situations — to bring with you to the appointment.
Step 2: Arrange legal documents early. While the person is still mentally capable, discuss healthcare proxy or durable power of attorney for healthcare — that is, who will have the right to make medical decisions on their behalf when they no longer can. Lawyers or organizations supporting elderly people like the Vietnamese American Senior Association in many major cities can help at low cost or free of charge.
Step 3: Learn about community support resources. The Alzheimer's Association has a 24-hour helpline, 7 days a week at 1-800-272-3900. Many local chapters in Houston, Orange County, and San Jose have staff who speak Vietnamese or have bilingual materials.
Step 4: Share the burden within the family. Don't let one person carry it alone. Hold a family meeting — whether by phone or in person — to assign responsibilities: who takes them to appointments, who manages medications, who stays overnight if needed. A clear schedule helps prevent misunderstandings and burnout.
Step 5: Take care of yourself. Caregivers face very high risk of depression and exhaustion. According to research published by the Alzheimer's Association in 2024, more than 60 percent of family caregivers report high or very high stress levels. Find a support group for caregivers — many Vietnamese communities in America now have these groups, both in-person and online.
Living with Alzheimer's — Not Just Waiting
The early stage of Alzheimer's disease does not mean everything stops. People with the disease can still enjoy life — visiting temples, listening to old music, cooking familiar dishes, telling stories of the past. Emotional memory and procedural memory — like how to play an instrument or fold newspaper — often last longer than event memory.
Many families find deep meaning in this stage — not because the disease is good, but because it forces people to spend time together in ways they had not done before.
Understanding the disease, recognizing the early signs, and knowing you don't have to walk this path alone — this is the foundation for your family to get through it.
