Hi Angie,
Cognitive impairment can be memory loss (usually short term), inability to concentrate, difficulty thinking straight, difficulty learning new things....and the list goes on. Math is especially difficult if you have this problem. I can remember years ago like it was yesterday, but five minutes ago, I have trouble with.
I'm afraid some morning I'm going to wake up next to my husband and not know who he is...lol I have forgotten my children's names, gotten lost two houses away from mine, been unable to find my street in my own neighborhood....and have gone into a room knowing I need more light and not being able to figure out how to get it. That is just a few examples. I have learned to laugh at myself, but it was an uphill battle.
I'm sorry you're having so much trouble lately Angie, I will keep you in my prayers.
Leona
