Sir, I am 23 years old male .I am suffering from anxiety and dysthymia for past 4 years, my mental capabilities have declined ,I took antidepressants for that ,but my mental function and foggy condition doesn't improve. I am facing academic difficulties and low performance in exams ,I am not able to concentrate in books and remember them. Is there any medication that can improve my cognitive functions or not. Because I want to score good marks and study hard but I am not able to do so. I have visited psychiatrists time and again but it doesn't help. I have tried antidepressant combinations also but it doesn't help. I was put on nortriptyline 25 mg bd .But I experienced tachycardia, rise in blood pressure with that so I began fearing that I might develop hypertension in younger age .So I didn't rely myself on nortriptyline. I only took half the dose 25 mg od due to fear of developing hypertension. Now I am on paroxetine 12.5 mg od. Would you please help me what to do Thanks Hitesh.
