8 Odds of concurrent mental disorder Rush 2010

9 Concurrent disorders Two or more chronic conditions Highly vulnerable population High burden of morbidity and mortality Under-diagnosed Under-treated Lacks a solid research base, as they are often excluded from trials

10 Why is overlap so common? Overlapping neurobiological pathways

11 Why is overlap so common? Overlapping neurobiological pathways underlying genetic factors (common vulnerabilities)

13 Why is overlap so common? Overlapping. neurobiological pathways and common vulnerabilities underlying genetic factors exposure to trauma, chronic stress, and loss

15 Why is overlap so common? Overlapping. neurobiological pathways and common vulnerabilities underlying genetic factors exposure to trauma, chronic stress, and loss Disorder as a risk factor for second disorder bi-directional complex inducting, propelling and upholding

16 Concurrent disorder Higher rates of: history of traumatization (childhood, adult) poverty and deprivation victimization, violence, incarceration, homelessness neurocognitive impairment cluster B personality traits relapse, hospitalization medical complications (Hep C, HIV, COPD, stroke ) Suicides Worse clinical course, treatment outcome and prognosis

17 Anxiety Disorders Concurrent Disorders Christian G. Schütz MD PhD MPH FRCPC Associate Professor UBC Research and Education Medical Manager BCMHA/PHSA Lifetime 25-35%

18 Anxiety Disorders cause clinically significant distress or functional impairment Concurrent Disorders Christian G. Schütz MD PhD MPH FRCPC Associate Professor UBC Research and Education Medical Manager BCMHA/PHSA Lifetime 25-35%

19 Affective Disorders cause clinically significant distress or functional impairment mood instability MANIC EPISODE Lifetime 40% dysth cyclothymia DEPRESSIVE EPISODE

37 Pharmacotherapy for Concurrent Disorders A thorough assessment is essential Consider sequence, time lines, and periods of abstinence Both substance use and mental disorder must be treated Little evidence beyond treatment of independent disorders Continue to re-evaluation diagnosis and medications

38 Polypharmacy risks with methadone/burprenorphine Additive or synergistic effects: sedating antidepressants antipsychotics Benzodiazepines! Additive side effects: QTc prolongation Haloperidol, Chlorpromazine, Olanzapine, Citalopram Pharamacokinetic interaction: CYP induction: Carbamazepine CYP inhibition: Fluvoxamine, Fluoxetine, paroxetine
