ELI5: Why are there risks of suicidal thoughts when taking antidepressants? What risk causes this?
gpt
It is not so much that the antidepressants cause suicidal thoughts, but they can, seemingly paradoxically, make people more likely to act on them. This is due to the fact that antidepressants take a while to even out your system. It's sadly not a case of starting to take them today and you start feeling better tomorrow. It takes a while and you start feeling better in stages. One of the first changes people notice is that they start feeling more motivated to do stuff.  The problem is that that increased motivation combined with already present suicidal thoughts might lead to an impulse to do something that one was previously too unmotivated to do. That is why it is so important to always keep in contact with your doctor when taking antidepressants and preferably to combine them with some form of cognitive therapy. That can help you deal with those impulses without doing anything that you might regret.
