My 72 year old Grandmother is having memory loss issue since last 2 years but it has increased since February 2019.She is unable to remember dates. Another thing is since August she is scared to be alone in home & sometimes she gets up at night & enquire about date & day. She doesn't have Hypertension,Diabetes or Cholesterol.She has thyroid since last 3-4 years.We had taken her to an Psychiatrist in October 2018 & had 3 seasons but no results. So we are confused what to do ??? Should we consult a psychiatrist or neurologist?????
