Bipolar disorder and MLC.
My mother was bipolar her whole life, when she hit midlife her BPD became much worse,
and her BPD was pretty bad to begin with.
In general any disease or malfunction of ones body becomes worse at midlife,
it is a fact that I can personally attest too, that my bad knees and bad shoulders are much worse now.
Stress can also worsen any diseases within your body,
look at home many people develop cancer at midlife too.
All that being said, MLC can also look like bipolar disorder, borderline personality disorder, depression or lots of other things.
So I think that it depends on what was diagnosed pre midlife, (or occurred as undiagnosed).
I see it quite easily confused between the two, and many people
are mentally ill and undiagnosed, so that adds to the confusion.
Did I say MLC = Confusion....... LOL!
I guess the point really becomes is that some mental illnesses can be controlled by medication.
MLC will not be controlled, just like giving a 13 year old a pill will not make them grow up.
Wish I could make this easier but none of this is easy.
