How can I tell if my mother has dementia?

That's a very hard thing for someone to diagnose on their own without medical assistance. Maybe google the symptoms you are seeing and take her to see her doctor to have it checked out?

By my experience it starts with small things, like forgettibg where you left things, but as it progresses there are tests that doctors can do to determine if it is dementia and how far along it is. (Nothing painful)

This isn't something you should decide or guess or try to figure out on your own. To really find out if your mother has dementia I would definitely consult a doctor and have tests done to find out.

If you suspect she does, do some research, and get a second opinion. Remember every individual is different, so only use the internet as a guideline. If you are concerned, seek a medical professional who can at least diagnose her, and advise you on how to help her if you so wish.

Take her to a doctor. You can't properly diagnose her if you're a member of her family and/or if you're not a doctor.

You can't really get an answer without professional diagnosis. I suggest you take her to the doctor.

Of course, the best way to know for sure is taking her to a health care provider, but I would look out for the following signs: -Does she ask the same questions over and over again? -Does she get lost in places she normally recognizes well? -Does she have problems following directions? -Does she get confused really easily? -Does she have problems with taking care of herself? Forgetting to eat, drink, shower, etc?

Notice if she has started forgetting stuff that used to come easily to her. like names of friends, relatives, family. or may be whether she has had her medication or even has done her day to day chores. If so then it would be a good idea to take her to a neurologist. May be its age catching up but its always good to be safe. They would sometimes even forget stuff like how to cook. or if you give them something to keep and they misplace it. Or if someone has an important message for you which they forget. The trick is to be very patient with them because they themselves are not aware why it is happening to them. I was unable to understand why my father would behave a certain way. which also brings me to the point that if you see any behavior change then that could also be a sign.

Only a trained professional can diagnose dementia. If you are concerned about your mother's mental health, have her consult with a health care provider to make the diagnosis.

That's a hard question to answer. Seeing a doctor would be the best solution. If you need support or someone to talk to, we're here for you.
