Serum S100B and antioxidant enzymes in bipolar patients.

Bipolar disorder (BD) is a chronic, severe, and highly disabling psychiatric disorder; peripheral markers have been used to assess biochemical alterations associated with BD and/or possibly involved in its pathophysiology. Beyond neuronal commitment, many groups have proposed the involvement of glial activity in psychiatric disorders. Other biochemical markers, particularly associated with oxidative stress, have been studied in BD.
