Major Depressive Disorder (MDD) is not necessarily lifelong; it is often episodic, and many achieve long-term remission. Your cognitive symptoms (poor concentration, memory loss) are likely linked to long-term Clonazepam use, which is typically not recommended for multi-year treatment. Loss of libido and enthusiasm are common side effects of Escitalopram. To minimize these side effects, your psychiatrist might recommend gradually and safely tapering off Clonazepam. To manage depression without these side effects, they may lower your Escitalopram dose, switch you to an alternative antidepressant like Bupropion (which has fewer sexual and cognitive side effects), or integrate psychotherapy. Never alter your doses without medical supervision.
