My son, 16 years old, had a head stroke in August, MRI and CT scan showed nothing, and the headache and eyes from the inside, memory problems persist continuously. The neurologist told me to go to a psychiatrist and he recommended Preato 75 mg, for 2 weeks a dose of 1/2 tabl in the morning and evening, in my opinion zero improvement, even my son says that he has trouble breathing, he is nervous, he says that if this pain does not go away, he has no strength to live. While using the drug I have the impression that he is more nervous, he is stuffy we are in sweatshirts he has short sleeves, the doctor told if after 2 weeks there is no improvement increase the dose to 1 tab in the morning and 1 in the evening and so we have already done 3 days he takes a higher dose but so far you can see 0 improvement, is this how it should be, I don't know what to do. Doctor on leave, no contact possible
