Is it obligatory to inform a suitor about a past mental illness, given that the condition has improved and one is committed to acts of worship?

A suitor must be informed of any illness that affects marital life, or the raising of children, or is repulsive to the spouse, or is real and permanent; because concealing it is a forbidden deception. As for illnesses that are not impactful, or are imaginary, or are temporary, there is no need to inform him of them.
