I was wondering about why a 72 year old would have violent tendencies?

There are many things such as UTIs, Dementia, medication, or withdrawals from caffeine, lack of certain nutrients, sugar highs, and lows. I would suggest you speak with her primary care physician to see what is going on with her.

If this is a recent change get her checked for a UTI. My mom's aggressive tendencies would escalate when she had a UTI.

Idk what to do n what kind of evaluation she needs .. can someone please help me to understand that ....also I was wondering. My mom's memory is really great. So can it still be dementia

Thank Yu I been reading a lot about dementia n Alzheimer's .....ever since I had ..well I thought a friend come cus I fell n broke my hip ....but it's been like mom is so much worse towards me ....I looked n the friend had dun everything I mean down to mom smoking n baby her very badly now she is really cruel n I mean tells me she hopes I die.....she threatens me n idk what to do....I promised her I wouldn't put her in a nursing home. ....she ask me about a durable p.o.a. about 6-8 months ago n we did .. mom was never like this. I've got no family or nothing ....not many friends who could really help me. I just can't make her get up. I meant to say also. She has lost a lot of weight but she still won't get up outta bed....she has arthritis n takes synthroid for her thyroid

These violent tendencies are part of her Dementia and it would help if you got her evaluated by a neurologist. There is medication for this but you need to know what type she has to get the right meds.

I agree, if you are going to care for Mom then you need to educate yourself.

In your profile you say that you don't know much about dementia, but that your mom has it. You obviously have access to a computer, so why don't you do some research, and check out some videos by Teepa Snow? The best way to deal with someone with dementia/Alzheimer's is to educate yourself, so you're not surprised or offended by things they do or say. The book "The 36 Hour Day" is also a very good source of education and information. If your mom in fact has dementia, her brain is now broken and won't get better, only worse, so it may be time to be looking for other options for her care. Best wishes.

Your profile information is helpful:
"I am caring for my mother, living at home with alzheimer's / dementia, hearing loss, and sleep disorder." She's 72 years old, which is fairly young.

When you say she "stays up so much" I'm assuming you mean she is awake. If I were in your situation I would call or take her to her doctor to make sure she isn't having something other than dementia/ALZ, like she could have a UTI, thyroid issues, overmedication. Does she have a history of mental illness, like bipolar disorder?

Are you her Power of Attorney? If not, and no one is, it would be very important to encourage your mom to assign someone so that she has a trustworthy and available representative to act in her best interests if/when she no longer can.

If she does have dementia, this sleep disorder/wakefullness at odd times can be a phase but it can also be addressed with medications, if she's cooperative.

Do you have any help with her care? If finances are an issue you may want to consider calling social services for your county at the Dept of Human Services online and request an in-home assessment. She may be qualified for some free services from Medicaid. I wish you much success in helping her get what you both need.
