[Prophylaxis of bipolar disorder].

Until recently, the psychopharmacological treatment alternatives for bipolar maintenance treatment were limited to lithium, which seems of special usefulness in a classical manifestation of the illness with mood-stabilising and anti-suicidal properties. With atypical features like psychotic symptoms or rapid cycling, lithium seems to be less useful. This led to further research into alternative options as carbamazepine, valproate or lamotrigine as well as atypical neuroleptics, thyroid hormones or innovative substances like omega fatty acids. This article summarises the current state of knowledge on treatment options for maintenance therapy.
