Has my relative had a mild stroke?

She has developed a slight slur, her mouth is slightly turned down on the left, her left eye is slightly turned down and her coordination is slightly skewed eg last week she could not get her seat belt on and kept on missing the lock. Also she has very little movement in her left arm. It seems to be getting worse but she is just pretending nothing is wrong. Any doctors out there?

In my experience, she has experienced a stroke. You should take her to see a physician as soon as you can. She may have some severe arterial occlusions which need treatment. In addition if she has had a stroke because of arterial stenosis then she is at high risk for a heart attack. Please take her to the doctor today. She is wrong. She has had a stroke. My mom had 2 and it took me a couple of hours to convince her to to go the ER.

I might add that her problem is in my opinion a very urgent problem and needs medical attention today.

Could be - or a brain tumor - see a doctor ASAP

She should seek medical advice immediately. it sounds possible that she could have ahad a stroke/minor stroke but no-one here will be able to diagnose this fully.

You need to see a doctor!! It could also be motor neurons disease this effects the signals between the brain and muscles making it difficult to perform simple tasks.

My mother had a mild/major stroke....yes, it sounds like one..she is foolish if she doesn't get help, before she has another, more serious one!!

There definately is something wrong judging by the symptoms you have listed.
She could have a whole host of things going on. She most definitely has neurological symptoms which need to be assessed and either stabilised or treated.

If she walked into my clinic like this she would certainly be told to go to A&E.

If she's reluctant to go to A&E herself call her doctor and ask for a home visit.
