Heart bulge and syncope. Can do further?

Hello doctor. My mother is having high BP for more than 12yrs.Last month she was diagnosed with heart bulge and now she is under treatment. She thinks too much Nd bcz of lack of sleep doctor also prescribed sleeping tablet. Almost every day she is losing her consciousness and dat time she is blabbering like m falling from somewhere Nd sumtyms she is crying.morning if we say she is asking m I saying like dat.she is getting syncope especially btw 7to9pm.we also took EEG and the result is normal. But I am still having a doubt that whether she is getting this syncope because of heart bulge and medication or any neurological related conditions. Please clarify my doubt doctor. What we can do further?
