Hi I am starting to get worried about my mom, she is 82 and have been noticing certain things with her, her memory has been terrible for awhile now, she is shaky, forgets where she puts things, she just had a server bladder infection this week,  and was very confused which I found out it is very common in the elderly, she use to be organized and is not the best anymore with it, her older brother had alzimers and has passed away, I am going down to see her tomorrow and have a doctors appointment on wednesday to talk wiath her doctor,
Hello, welcome to Chat Doctor. She appears to have dementia considering old age, memory loss, disorganized behavior and history of Alzheimer in brother. Early cases of Dementia respond well to treatment by neurologist. If symptoms are recent in onset and associated with bladder infection, then there is need to rule out delirium due to poor medical condition in her case. Wish you good health and all the best.
