Methods: We report a patient with a bipolar disorder, who experienced a hypomanic state under an established drug treatment with valproic acid and olanzapine. For evaluation of therapeutic response to low dose quetiapine, structured clinical interview and discrete EEG analysis of initial and follow up recordings were administered.
Results: Administration of a low dose of 50 mg quetiapine per night as an adjunctive treatment to prescribed psychopharmacologic drug formulation was followed not only by the intended improvement of sleep comfort, but also by a complete control of hypomanic state. Clinical improvement was accompanied with a restoring of initially EEG recorded patterns of impaired vigilance regulation.
Conclusion: Our report emphasizes the advantage of stratifying presumed effectiveness of quetiapine already at low dose administration in controlling exacerbated bipolar disorders by combined clinical and neurophysiological approaches as suggested by EEG, in particular due to specific stabilizing mechanisms at the cerebral vigilance regulation system.
