Stages of Alzheimer’s Disease and What to Expect

October 28, 2011

First blanking on a grandchild’s name, then accusing a son or daughter of stealing personal belongings, to eventually not recognizing close family members—this is the heart-breaking long goodbye, also known as Alzheimer’s disease. One of the scariest parts of Alzheimer’s can be the unknown of how it will affect your loved one day to day, month to month and year to year.

Alzheimer’s is a progressive disease, meaning symptoms will gradually change and become more severe. While these changes affect everyone in different ways and at different paces, it does follow patterns that enable you to understand the affected person’s level of cognitive impairment and plan accordingly for the additional care that will be needed along the way.

The phases of Alzheimer’s are typically grouped into three main stages:

  • Mild (early)
  • Moderate (middle)
  • Severe (late)

The following information, gathered from, the Alzheimer’s Association and Dr. Barry Reisberg’s Global Deterioration Scale, describes each stage in more detail.



  • Repeating questions or comments without realizing it, often within the same conversation
  • Misplacing objects or storing them in an unusual spot
  • Difficulty comprehending, retaining and recalling new information (yet memories from long ago are vivid and easily recalled)
  • “Good” days where your loved one seems completely normal and “bad” days when his or her cognitive impairment seems more pronounced and interferes with daily life
  • Avoiding regular activities that have become more difficult in order to minimize embarrassment and frustration. Mood changes may accompany these frustrations

Care Considerations:

  • For the most part, those in the early stages of Alzheimer’s can remain independent in carrying out their normal activities of daily living
  • It will become increasingly helpful or necessary to provide assistance with complex tasks like managing finances, keeping track of appointments, following a recipe and going to unfamiliar places. Whether it’s you, another family member, a neighbor or a hired companion who stops by several times a week, it’s important to have a support system in place
  • If incidents of getting lost, locking the keys in the car or house, or forgetting to turn off the oven become more prevalent or hazardous to the safety of your loved one and others, it’s time to re-evaluate the level of care



  • Greater difficulty with social situations and communicating appropriately
  • Decreased sense of time
  • Increased irritability due to frustrations from declining abilities
  • Withdrawal from daily activities that have become too difficult to handle
  • More frequent and prolonged memory lapses
  • Periods of disorientation, regardless of familiarity with environment
  • Difficulty reasoning and making good judgments
  • Changes in behavior that may including wandering; rummaging; delusions or hallucinations; expressions of anger aggression, or anxiety; shouting; and disrupted sleeping and eating patterns
  • Care Considerations:

    • Daily support is needed during this stage of Alzheimer’s, whether from family members or trained professional caregivers
    • External memory cues and verbal prompting should accompany every activity
    • Maintain a daily routine and minimize change as much as possible
    • Allow extra time to perform tasks
    • If violent or aggressive behaviors become frequent, incontinence becomes an issue, or you see a decrease in mobility, talk to your loved one’s doctor. It may be time for a more advanced level of care



    • Difficulty or complete inability to recognize familiar people, including close family members and even self
    • A lot of time spent sleeping
    • Nonsense speech including babbling or making strange noises
    • Loss of motor skills and sense of touch
    • Cognitive abilities similar to those of a 2 to 5 year old

    Care Considerations:

    • Someone entering late stage Alzheimer’s will require personal care assistance to bathe and use the toilet or manage incontinence
    • 24/7 care is needed as the person becomes completely dependent on others
    • Safety and fall-prevention measures must be taken to accommodate decline in mobility
    • May become more susceptible to other illnesses
    • Even though the person with Alzheimer’s may not seem to remember, recognize or respond to anything, he or she can still feel personal touch and loving attention
    • Depending on the severity of symptoms and behaviors, skilled nursing, palliative or hospice care may be needed

    No matter which stage your loved one falls into, it’s important to focus on what he or she CAN do rather than which abilities have declined. Helping a loved one through such devastating changes puts a lot of stress on you as the caregiver to continue providing the best care possible. But whether or not it seems as though your loved one with Alzheimer’s or dementia can understand and appreciate your efforts, know that he or she will always be able to feel your love.

      My mom's stage was just switched to moderate to severe last October. In the last few days she has went off a cliff again. Only this time it's quite bad. I moved her to a Assisted Living facility with a Memory Care unit on site a year and a half ago and I believe I may have to have them move her to the Memory Care Unit in the next week or so. If you're providing care to your loved in your own home or theirs, please understand you can't continue to do that. You will need others to help you. If you're young enough and wish to do this, kudos to you, but it will take its toll on you and your own family. Don't let this happen because it will also take its toll on the person you're caring for. All in all, don't try to be the hero here. I know because I wanted to to it all but finally found after 62 years, I was basically throwing myself under the bus and I was no good to anyone. You need to remember to be kind to yourself. The person with Alzheimers isn't going to thank you and won't ever remember that you took on their care, but you will be in a better position to actually help more when you have your own sanity back. Talk to others but always remember, be kind to yourself as well.

      My Dad is having very bad days.Very aggressive,angry & doesn't trust us.He throws things,saying my mom's & family are steeling his money.We are afraid he will hurt our mom.We brought her to our house because he had another bad day.

        Hi, I hope things are getting better for your dad and your family. Everything that you are saying sounds very familiar to me as my mum who lives with me had a fall on New Years Day and wouldn't go to hospital until I had no option but to call a ambulance after 24 hours,and then she was telling the ambulance team that she was fine and wasn't going anywhere. Anyway to cut a long story short she had dislocated her hip and needed a operation.She was in hospital for 9 days and at 79 I was eager to get her out of there as she was getting very depressed on the ward and was showing signs of delirium which the nurses told me was very no

      I am looking to speak with anyone similar to my position or my mother's that can give me some insight. Or maybe just someone to talk to. I live at home with my parents and my grandmother. My grandmother is my mom's mom. She has Alzheimer's - middle stage. I see the caregiver stress in my mother every day. Not only is my grandmother not the woman I remember, but this disease is taking its toll on my mother and the way she treats others around her because of the stress this has put on my mom. My mom is now becoming someone she is not, just because of what she has to deal with on an on-going basis. I want to move out so I can get my life back on track and ensure that I live without stress to keep my mental health on track (I used to suffer from Depression) but I feel guilty leaving my mom to deal with my grandmother on her own. I just want peace for everyone - help.

      My dad is currently in the sever stage and was admitted to a lock down psychiatric unit last Monday. They have to constantly drug him. He can only stay 10 days. What do we do after the 10 days? If he is not even stable to go to a care center?

      I am a 56 year old woman, I moved in to help with my dad who has stage 2 alzheimers, my mom had a stroke last year and is not in the best of health, but is really the sole caregiver of my dad I work 10 hour days four days a week. My dad is getting worse every day, he still tries to control everything my mother does, he thinks she is having an affair with our preacher to the point I will probably quit taking her to church one of the only things she does. I am so annoyed with him and this horrible disease. I try to have compassion but I hate seeing what this is doing to my mom. I know she doesn't want him to go to an assisted living facility, but this is so hard to see. I find myself wishing God would take him home, then feeling guilty for feeling this way. Any advice would be appreciated

        My mom is going through the same thing with my dad, he keeps accusing her of having a affair with someone. It's hard to see my dad like this because he's just a different person. I know there is no help for him, but what do I do for my poor mom. She is in hell. I find myself hoping god would take him, because this is not the life he wants too live. I also feel like my mom is going down hill. I can't let him kill my mom..

      I have been taking care of my mom for the last 2 years. She is in the late stages, incontinent doesn't know us and is basically lost. Imagine just being lost. Every second on every day. Mom has fallen twice in the last 5 days. First time I called an ambulance because I panicked because of the blood. They didin't admit her because there was really no reason too. The second time my husband and I just helped her up and she seemed fine. It is horrifying to watch someone die every day because that's what it seems like. I can't believe that we can put a dog or cat out of it;'s misery but not a loved one....

      I have a friend who's grandma raised her since she was about 8 years old due to her mother abandoning her and her two sisters. Last summer, my friend's aunt came through and got temporary guardianship of the gma, evicted my friend, and put her on a no contact list. At that time, to our knowledge, she had not been diagnosed with Alzheimer's. My friend had taken her to the doctor and the doctor said no memory loss. Then, an affidavit showed up for 5 days later from the same doctor that said dementia and the doctor's office gave it to the aunt who used it to get her gma. Now, she has been diagnosed. The courts finally ruled 2 weeks ago that my friend could go see her gma with the Guardian Ad Litem present. So, she went and saw her. The gma had no recollection of myself, husband, or kids who were over there EVERY DAY and she thought my friend was trying to kill her which she would NEVER hurt her gma. Gma said she had nothing nice to say to her grandma and didn't want to see her. It broke all of our hearts especially her. That's really going to hurt my friend's contested guardianship case, but aside from that what stage does this seem like it is? Is that normal to think someone that would never hurt you was there to kill you after not seeing them for 9 months? Also, 2 weeks prior to the visit, another friend called the assisted living home to talk to the gma and the gma said she wanted to talk to her grand daughter and she didn't know why she was there. Then, 2 weeks later she thought the grand daughter was going to kill her and one night they almost had to sedate her because she thought her grand daughter would kill her so the nurses told her she had been arrested and that helped the grandma sleep. Aren't the nurses just adding to gma being afraid by lieing like that instead of letting her know that no one is out to kill her? Is this normal? I just told my 3 boys that gma loves them because the gma they knew did love them:( Please help my understanding.

      If you are like me, I read every book about this subject and many made a person feel guilty if you put your loved one in a nursing home. My dad became more than my Mother and I could handle at home. We had him going to an adult day care while I was at work and then someone to stay with him and my Mother until I was off work and available to help her. We did this until it wore both my Mother and myself down and Daddy was not a happy camper either. We admitted him to a nursing home (for people with memory problems) and he is so much happier. He is able to wander all over the facility (they can't open outside doors) doesn't feel caged in and they are able to help him bath, dress and take care of his needs much easier than we were. Now when we visit it is to see him and not "Do Things" for him..Of course there are things that we don't like, but it is things that bother us, not him. He may not get a shave as often as we would like, or he may have mismatched clothes on, but this is stuff that isn't important to him, so we try to let it go. Good Luck and whatever you choose to do, remember it is what is best for your family, no one can tell you what you need to do, they are not the one who is living your life.

        Thank you for sharing your experience with the nursing home. My mother's long-time companion is now at a nursing home. I now listen to her complain about how the care is at the nursing home (he's not dressed in "his" clothes, the nursing home has him drugged, the care at the nursing home costs too much, on and on). After listening to my mother's diatribe today, I googled the stages of the disease and found this website and your experience with your father. I was grateful to read how you and your mother's attitude toward things at the nursing home. I'm going to try to get this across to my mother. Wish me luck!

      My grandpa is entering the severe stage. He was in mild for about 3 and half years. The moderate for 2 years in the past 2 to 3 months it has jumped from moderate to severe from day to day. For the last two weeks it has been complete severe. Luckily he is a very happy go lucky person with Alzheimer's. He talks alot of non sense and makes up stories. His long term memory has always been good till recently. And now my most major issue is that me and my fiance live with him to take care of him, he is sure that she is his wife and that I am trying to take her from him. He literally gets mad if we even act the least bit close to each other around him. It scares her pretty bad. He tries to go in the bathroom while she is in the shower and has walked in our bedroom more than once with her dressing. Now we have locks so it can't happen again. Some days he's fine with her but other's it's worse. We don't want to put him anywhere but if it gets any worse I don't see another way. We have him on Lexapro, Namenda and Syriquil. Without those he would already be gone. Anyone have any suggestions on what to do or say when he starts acting like she is his wife or gf? Thanks for any advice.

        I'm sorry you and your fiancé are having this troubling situation with your dad but glad he's a happy go lucky person - that makes caregiving a bit easier. Try to redirect your father when he thinks your fiancé is his wife, say something like, please tell me about your wife or ask your fiancé to ask your dad about his wife. It probably won't do any good trying to correct him. I found support groups very beneficial. Good luck and God bless.

      I am interested in the "Severe" stage and how to know if it's best to keep my mom "OUT" of the rest home or accept she need to be in one? Thank you and GOD BLESS!


      • January 24, 2014 at 1:01 am | Posted by dylan

        If you can safely keep her and take care of her I would. But that's just me personally. Only reason I say that is my fiance works in health care both assisted living and also has in nursing homes. Their is not enough workers in the places to provide complete around the clock care for your mom. Just an example: where she works now it is her and 2 other co workers for 79 residents. And like she told me they can't watch and keep up with everyone at all times. Not to mention the mean and rude ones that could care less how long someone lies around in their own urine. If you can't take care of her and are to the point she needs to go somewhere. I would only put her in one that has a lock down unit. Cause even though they can't always be by her side at leastcshe can't get out and do anything to harm herself. Good Luck.

      My husband refuses to wear Depends and is confused about where to urinate so does it just about anywhere; also this happens sometimes with defecating. He gets very angry with me when I try to get him to wear a product, and screams at me and calls me names and orders me to get out. Does anyone have a good idea for protecting wood floors against this urination, or ways to cajole a very stubborn and unduly prideful person to wear protection? Of course, there's no reasoning with him and I also can get very angry with him and these "battles" take so much out of me.


      • March 10, 2014 at 2:16 pm | Posted by S Davis

        I empathize with you and for your husband. Any chance your husband would listen to his doctor if the doctor told him that he/she is writing him a prescription? Sometimes a person will listen to the doctor's advice. Good luck.

        What about a condom catheter or washable underwear. With built in pads they sell on internet? Look under high tide on internet

      I am particularly interested in information/personal histories of persons in the "Severe" stage as that is where my husband is now. Thanks.
