Depression & mood disorders

Major depression, persistent low mood, and the depression that has not responded to treatment after treatment.

Depression is common; depression that has not responded to several adequate treatments is less so, and it deserves a different kind of attention. Much of Dr. Pellionisz’s work is with people for whom the standard sequence has not worked.

Who this is for

  • A first episode of major depression, where getting the initial treatment right matters most.
  • Recurrent depression, or depression that returns each time treatment is stopped.
  • Persistent depressive disorder — the long, low-grade course that is easy to mistake for temperament.
  • Depression that has not responded to two or more antidepressants at adequate dose and duration.
  • Depression complicated by anxiety, insomnia, attention difficulties or a possible bipolar course.

How we evaluate

“Treatment-resistant” is a description, not a diagnosis. Before adding a fourth medication the practice asks what the first three actually showed: were they taken at a therapeutic dose, for long enough, and did anything change? Was the diagnosis right — is this unipolar depression, or a bipolar-spectrum illness, or a mood disorder secondary to a medical or sleep problem? The evaluation builds a longitudinal timeline of episodes, treatments and responses, so that the next step is chosen from evidence rather than from the last thing tried.

Treatment

  • Medication, precisely. Antidepressant selection and optimization, augmentation strategies, and — where the history warrants it — a change of diagnostic frame that changes the medications altogether.
  • Psychotherapy. Evidence-based approaches delivered in the practice or in coordination with your existing therapist.
  • Image-guided TMS. For depression that has not responded to medication, transcranial magnetic stimulation with personalized targeting informed by your own imaging. Read about TMS in this practice.
  • Measurement. Standardized symptom measures at each visit, so that improvement is documented and the plan changes when it stalls.
Next step

When treatment has not held.

If several medications have helped only partly, or not at all, the next step is usually a better question — not another prescription.
