Regarding the question of ADHD (sometimes referred to as ADD), at times it is diagnosed in adults, especially if it is the predominantly inattentive type; as children, these kids are less apt to be disruptive in the classroom, and if they are otherwise bright they can manage to compensate for their attention/concentration problems enough to get by. That said, I see an awful lot of people who seem to think they have ADHD, but when I finish treating their depression/anxiety
/whatever, their concentration problems are no longer an issue. For this reason, I insist on fully treating those problems first if they are present in an individual who is concerned they may have ADHD. Also, because there is a very high abuse potential risk with most of the medications used to treat ADHD, especially in patients with a history of substance abuse
, caution must be used in diagnosing ADHD when there could be other motivation (i.e., substance-abuse) for seeking treatment for ADHD.
Regarding the use of lithium in pregnancy, I would be very cautious about this. At times, the risk of discontinuing a medication during pregnancy is very high and must be considered, but the general thinking is still along the lines that lithium can/does still increase the risk of Epstein's Anomaly in the heart.
Likewise, the accepted belief about bipolar disorder is that it is a lifelong illness.
Of course, patients commonly have more chaotic lives in their adolescence and young adulthood, for many reasons. I think the question is maybe not so much whether they outgrow bipolar disorder as it is whether or not they ever had it in the first place (versus having maturity issues, limited coping skills, substance abuse issues, hormonal fluctuations from puberty that haven't settled down, etc.) I hope this helps.
