Hello, I have a senior citizen at home , she is diabetic and on insulin and oral hypoglycemic drugs for the same. I am just concerned about her psychological health because she talks too much and repeat conversations multiple times. Sometimes she talks non stop for almost 2-3 hrs without stopping and switch the conversation from one topic to other without nay hault. She also doesn't understand weather you are talking to someone on phone or you are sleepy or have some work to do. I just want to know weather this is normal at her age or initial stage of some disorder. Kindly help.
