From the description if the description is correct it seems that your sister is having amnesia. Amnesia is of different types and proper evaluation and treatment is required. First take your sister to a physician and the physician should decide what type of treatment she needs. Psychologist can do a bare minimum in amnesia. Probably you need to visit a neurologist.

I shall prescribe the needed psychotherapy techniques. Hope this answers your query. Available for further clarifications. Good luck.
