Hello, I am just concerned for a family member. She is a 73 yr old lady, I have noticed this past yr, she stammers over some words and sounds. Repeats things every so often, even after a few mins. Last night she even could not get the word Cat out. She forgot how to say it and was putting the letter R in Cat and kept saying crat, over and over. She has been getting dizzy and off balance once in awhile too. Too add, probably about a month ago, she told me, she was alerted by her partners daughter that she called him 3am in the morning and she had no memory of this.Other wise, she seems to be ok with every other life activity. I don't want to say anthing as of yet, just don't want to stir the pot. Thank you in advance for the help.
