My mother expired on 15 feb 16. On the next day of cremation on 17 feb, my elder brother aged 38 lost his mind balance. Starting irrelevant talks, sleeplessness, fear, anxiety, aggravate sometimes... This is the second attack almost after 11 yrs when my elder mom expired. Consulted the doctor who prescribed following
