• Resumen

  • Thirty-five bipolar patients (8 men) completed a 20 minute verbalization protocol including narration of story passages, spelling of words backward, and repetition of a single phoneme. Protocols were recorded during the manic phase, depressive phase, and in the euthymic phase. A clinical and euthymic period were recorded in 18, and in 4, all three phases. Several characteristics showed significant differences between depression and euthymia including fundamental frequency and spectral distribution. Jitter and shimmer were greater during affective episodes. Spectral distribution showed opposite changes during depressive and manic phases. These factors help understand both commonalties and differences in psychological states, and may be used in diagnosis.
