[Treatment of acute bipolar disorder. Intriguing balancing act between mania and depression].

The term bipolar disorder is no longer limited to the classical manic-depressive condition, but now subsumes a wide spectrum of illnesses. As a consequence of this expansion of the classification systems, the therapeutic utility of lithium and other mood stabilizing agents has to be defined anew. The majority treatment recommendations differentiate, symptom-related, between euphoric mania, mixed conditions, mania with psychotic symptoms and rapid cycling manic episodes. Current acute treatment includes, in addition to lithium, in particular carbamazepine and valproate, but also newer antiepileptic drugs such as lamotrigine or atypical neuroleptic agents such as olanzapine and risperidone. Due to the high suicidal risk, patients with bipolar depression often need to be given an antidepressant as well. It must, however, be remembered that in patients with rapid cycling, antidepressants may re-trigger mania.
