A 7 stages of Alzheimer’s chart gives you a map when everything feels out of control. It cannot tell you how fast your mother or father will move, but it can help you ask better questions and plan before a crisis. I have helped many Long Island families use it that way.
The short answer: the seven stages run from no symptoms to severe decline, most people spend the longest time in the middle stages, and the timeline differs for everyone. I am Mike McClernon, a senior living advisor with a dementia care certification. I am not a doctor, so use this chart to prepare for the conversation with your parent’s physician.
What is the 7 stages of Alzheimer’s chart?
The chart below follows the common Reisberg scale, grouped the way many doctors describe it: before symptoms, early, middle and late. It fits Alzheimer’s best. Other kinds of dementia can look different, so I wrote about the broader picture in the 7 stages of dementia before death.
| Stage | Group | What you may see | What families can do |
|---|---|---|---|
| 1 | No symptoms | Normal memory and function | Healthy habits, regular checkups |
| 2 | Very mild | Slips that look like normal aging | Mention changes to the doctor |
| 3 | Mild, early | Word finding trouble, lost items, weaker planning | Get a workup, sign legal documents |
| 4 | Moderate, early middle | Forgets recent events, trouble with bills and cooking | Add supervision, review driving and money |
| 5 | Moderately severe, middle | Needs help picking clothes, forgets address | Daily help, tour memory care if needed |
| 6 | Severe, late | Needs help dressing, bathing, toileting, personality shifts | Full time supervised care, comfort focus |
| 7 | Very severe, late | Little speech, limited movement | Comfort, dignity, talk with the doctor about hospice |
People are not locked into one row. Someone may have a stage 4 memory and a stage 5 problem with dressing. Use the chart to see the direction, not to grade your parent.
Doctors may also describe Alzheimer’s in three broad phases: mild, moderate and severe. The seven stage chart simply splits those phases into finer steps, which can be useful when you are deciding whether a parent still needs only reminders or now needs hands on help every day. If a doctor or a community uses a different system, ask them to translate it for you. The names matter less than what your parent can and cannot do safely today.
How does Alzheimer’s affect the brain?
Alzheimer’s disease damages and kills brain cells. Researchers link it to clumps of a protein called amyloid between cells and tangles of another protein called tau inside them. The first damage often shows up in the part of the brain that forms new memories, which is why the early sign is forgetting recent events while old stories stay clear.
As the disease spreads, it reaches areas for language, judgment and movement. That is why the middle and late stages bring trouble with words, safety and finally body functions such as swallowing. Researchers are still learning why it starts. For symptoms in more detail, see the symptoms of Alzheimer’s disease.
When can Alzheimer’s disease start?
Most people who get Alzheimer’s are over 65, but the brain changes can begin ten to twenty years before the first symptom. A smaller group develops early onset Alzheimer’s in their forties, fifties or early sixties, and it is often missed because no one expects it.
Age is the biggest risk factor. Family history, certain genes, head injury, high blood pressure, diabetes, hearing loss and low activity can also raise risk, according to published research. Having a risk factor does not mean someone will get it, and having none does not protect anyone.
If you are worried about a parent who is younger than 65, push for an evaluation and bring specific examples. My post on how early dementia can start goes deeper on age and what to ask.
What is Alzheimer’s rage?
Alzheimer’s rage is the sudden anger, shouting or aggression that can appear in the middle stages. It is frightening for the family, but it is not the person’s character. It is the disease, plus a trigger you may be able to find.
Common triggers
- Pain, hunger, thirst, a full bladder or constipation.
- Feeling rushed, corrected or talked down to.
- Noise, crowds or too many people in the room.
- Tiredness, especially late in the day.
- Fear during bathing or dressing when a stranger touches them.
What tends to help
Stay calm, lower your voice, give space and do not argue. Agree with the feeling, then change the subject or the setting. Keep a short log of when episodes happen and share it with the doctor, who can check for pain, infection and medicine effects. Never give or change a medicine on your own.
Anger sometimes comes with delusions or hallucinations. See what stage brings hallucinations for how staff respond. If you ever feel unsafe, step away and call for help. Your safety counts too.
Where does care fit at each stage?
In the early stages, most people can stay at home with support from family. Assisted living can make sense for someone who is lonely, forgetting meals or medicine, but is still mostly independent. In the middle stages, memory care for Alzheimer’s and dementia is often the better fit, because staff are trained for dementia and the building is secured.
Families ask me about nursing homes. A nursing home provides skilled medical care around the clock, and a person with Alzheimer’s usually needs that only if they have heavy medical needs. I explain the difference in assisted living versus a nursing home on Long Island.
Here is my rule of thumb. Do not wait for a fall, a hospital stay or a wandering episode. Start visiting when your parent reaches stage 4. That gives you time to choose with your parent instead of for them.
If you are not sure how to compare communities, what a senior living placement agency does shows how a free advisor can narrow the field.
What should you ask the doctor about the stages?
Ask where your parent seems to be on the scale, what changes to expect in the next year, and what you should do now. Doctors are often glad to answer when you come with a short list, and the answers help you plan the move before it becomes urgent.
- Which stage do you think my parent is in, and what is that based on?
- Could anything else be adding to the confusion, such as a medicine, infection or low mood?
- What changes should I watch for, and which ones mean I should call you right away?
- Is driving, cooking alone or handling money still safe?
- Who should I see next, such as a neurologist, a memory clinic or a social worker?
Write the answers down and share them with siblings so everyone hears the same thing. Disagreement in the family is common, and a shared set of notes keeps it calmer. Bring a second person to the appointment if you can, since it is hard to take in everything at once.
Remember that the chart describes the illness, not the person. Your mother can still laugh at an old joke in stage 6, and your father can still enjoy a song in stage 7. Plan for the stages, but spend your time on those moments.
Getting help from Mike in Glen Cove
I am Mike McClernon of Assisted Living Locators of Long Island. My help is free to families, and communities compensate me when a family moves in. I have toured more than 90 communities across Nassau County, Suffolk County and Queens, and I plan 18 to 24 months ahead so the next stage is already part of the plan.
One call covers care needs, personality, location wishes and finances. Then we tour together and I help compare offers and paperwork, and I follow up after move in. My office is at 42 Prospect Ave, Glen Cove, NY 11542. Take a look at our memory care options, read the Alzheimer’s and dementia memory care guide, or contact Mike to set up a call.
Questions readers ask
Does Alzheimer’s skip a generation?
No. Alzheimer’s does not skip generations in a predictable way. Family history raises risk a bit, and rare gene changes cause early onset in some families. Most cases are not directly inherited.
What is the biggest difference between Alzheimer’s and dementia?
Dementia is the umbrella term for symptoms such as memory and thinking loss. Alzheimer’s disease is the most common cause of dementia. Other causes include vascular disease, Lewy body disease and frontotemporal disease.
When was Alzheimer’s discovered?
Dr. Alois Alzheimer described the disease in 1906 after studying a patient’s brain. The condition took his name a few years later.
How common is Alzheimer’s?
It is very common. Millions of Americans live with it, and it makes up most dementia cases. The risk rises with age.
Is Alzheimer’s inherited from mother or father?
It can be passed down in rare early onset forms, from either parent. For most people it is not directly inherited. Ask the doctor about your own family history.
