My sister-in-law has history of TIA, recently. She has suffered a memory lapse of about 3 weeks earlier this summer where she deleted all her phone information and doesn t remember doing it. In the past 3 to 4 days, she has become very agitated, flat affect when and if you can get her to talk, and anything more than yes, no, or one or two word answers, she has a very angry tone. She speaks very rudely to her husband, children, and siblings that have tried to help. Her siblings feel she is having a nervous breakdown...I fear it is something physiologica, perhaps undiagnosed stroke residuals. She won t make eye contact with anyone either.
