Hi! I'll be glad to be of help with this issue.
I can imagine how worrisome this situation must be for you. It must be very distressing that your son is going through this. I'm saddened to hear it but I'm glad that he's emerging from the manic episode.
First, let me say that if his manic episode included psychotic features, it is possible that the psychiatric condition itself is responsible for the memory problems. This can occur.
It is also not unusual for the combination of the recovery from a psychotic manic episode and the medications that are helping him stabilize from the episode to cause memory problems. These are indeed powerful medications that work in powerful ways on the brain. And so they can have this effect. But we have to remember that their main effect of stabilizing his moods is so important that the doctors are most often willing to take the memory problems as a short term side effect.
If the memory problems continue, then you might need to contact the doctors to see if the medications' dosages can be adjusted or the medications replaced with other medications that might not have this side effect. But the problems may ease up on their own. You should also make sure that the doctors have included in his treatement plan psychotherapy with a psychotherapist experienced in dealing with Bipolar Disorder and psychotic episodes. This is important as it will allow for quicker lowering of medication levels and thus earlier cessation of side effects.
Okay, I wish you the very best!
