3 The aches of the psyche … I do not like my state of mind I'm bitter, querulous, unkind. I'm bitter, querulous, unkind. I am always anxious and tense my thoughts make no sense my thoughts make no sense I dread the dawn's recurrent light; I hate to go to bed at night. I hate to go to bed at night. I find no peace in paint or type My world is but a lot of tripe. My world is but a lot of tripe. I'm disillusioned, empty-breasted For what I think, I'd be arrested. For what I think, I'd be arrested. I am not sick, I am not well My quondam dreams are shot to hell. My quondam dreams are shot to hell. My soul is crushed, my spirit sore; I do not like me any more. I do not like me any more. I want to stop this pain … before I turn insane Adapted poems

5 Greek Mythology THE ALGEA were the spirits of pain and suffering of both body and mind and are related to Oizys, the goddess of misery and sadness, and Penthos the god of mourning and lamentation. Mens Sana en Corpora Sana Decimus Iuvenalis

6 Why Pain, psychological distress (Anxiety and Depression)? Anxiety, Depression and Pain Symptoms are highly prevalent conditions –Lifetime prevalence of Pain = 24-37% 1 –Lifetime prevalence of Depression = 5-10% 2 –Lifetime prevalence of Anxiety= 20% 2 Anxiety, Depression and Pain complicate each other, affect outcomes, cause more morbidity and disability and increase costs.

8 Strength of association (D/R – Predictive) – –Can Pain be distressing? What is the prevalence of Anxiety & depression in painful disorders? – –Do depression & anxiety hurt? What is the prevalence of pain symptoms in Anxiety & depression? Does the presence of pain affect recognition and treatment of anxiety / depression? What is the common neurobiological basis of pain/anxiety/ depression? What are the treatments available?

9 Can pain be distressing ?!! The prevalence of depression in pain disorders [1] –In general population pain = 18% (4.7%-22%) –In Primary Care clinics = 27% (5.9%-46%) –In pain clinics = 52% (1.5%-100%) –In orthopedic clinics = 56% (21%-89%) –In dental/facial pain clinics = 85% (35%-100%) –In gynecology pelvic pain clinics = 13% (12%-17%) Prevalence of anxiety disorders in patients with chronic pain –In general population= 35 % [2] –back pain clinic = 20% - 57% [3,4] 1- Matthew et al Arch Intern Med. ;163: , Manchikanti et al Pain Physician, Volume 5, Number 2, pp , Sommer 18th European Congress of Psychiatry.

Ohayon & Schatzberg Arch Gen Psychiatry. 2003;60:39-47 Does Depression Hurt?! Pain was 4 times more likely in subjects with major depressive disorder (OR 4.0; 95% CI, )

15 Does Depression Hurt?! Results from the FINDER study Demyttenaere et al (2010) Journal of Affective Disorders –60 FINDER was a 6-month prospective, observational study of 3468 outpatients with depression initiating antidepressant treatment. 56.3% experienced mod/severe pain 53.6% had mod/severe pain-related interference with functioning.

29 The effect of poor recognition on the patients treatment Mistreatment Under treatment Decreased treatment efficacy Polypharmacy –Increase risk of side effects /drug interactions –Increase risk of substance misuse

30 The effect of poor recognition on the treatment outcomes Increase depression Increase Pain Increase functional disability Decrease quality of Life Increased Relapse Rates Decreased Remission Rates Increase health care utilization Increase suicide rates

31 Pain is an independent risk factor for suicide [8] Chronic pain associated with increased risk of suicide [1, 2, 3] Rates of suicidal ideation & attempts [4, 5] Rates of suicidal ideation & attempts [4, 5] Over 30% of chronic pain patients reported suicidal ideation [6] 37% of patients receiving opioid therapy reported suicidal thoughts & 20% an attempt [7].

33 The biology of Pain Sensory channels: –Sensory discriminative component –Motivational affective component Pain Modulation –Spinal Modulation (Gate Theory) Melzack and Wall 1965 –Descending inhibitions Opioid system 5HT system NE system Others –Descending facilitation

34 Sensory- Discriminatory pathway Motivational Affective pathway Stahl, 2008 Ascending pathways

35 Descending Inhibitory System Opiate (endorphins) Serotonin Norepenephrine Sub P (NK1,2,3) VIP (VIPR) Somatostatin Calcitonin GABA Glutamate Glycine NMDA NO CCK Sympathetic Stahl, 2008

36 Descending Tracts

37 PAIN: Depletion of monoamines Increase CRF IL2 – TNF –IL6 DEPRESSION & ANXIETY: Endogenous Opiates Endogenous Opiates NE - 5HT NE - 5HT CCK Sub-P Possible Explanation: Descending Pathways

38 Distress and pain disorders share the same anatomical sites Process information from sensory to emotional (mood & pain) executive functions & perceived control over pain Rational cognitive functions & pain processing memory of emotional reactions Associative and episodic memories Reward increases in negative affects

39 Induction of Negative Mood Disrupts Emotion Regulation Neurocircuitry and Enhances Pain Unpleasantness Berna C et al. Biol Psychiatry 2010;67: Negative or neutral moods were induced in healthy volunteers who underwent heat pain whilst in an fMRI scanner. Areas that showed increased activity during pain in the depressed mood state - left insula, thalamus, hippocampus, IFG, dlPFC, OFC, and the sACC. The thalamus and the insular cortex are part of the afferent nociceptive network. dlPFC, dorsolateral prefrontal cortex; IFG, inferior frontal gyrus; OFC, orbitofrontal cortex sACC – subgenual anteria cingulate cortex Pain was rated more unpleasant after the sad mood induction. Depressed mood was associated with increases in negative pain-related cognitions (catastrophizing)

40 Pain Proposed cognitive models Berna C et al. Biol Psychiatry 2010;67: increased negative mood increased catastrophizing increased pain unpleasantness induced Negative mood Pain related cognitions Increased catastrophizing (rumination) Mechanisitic hypothesis: Dysfunction of emotion regulation Increased cognitive load Change in neural processing in prefrontal areas Increased activity in the left IFG, dlPFC and OFC Increased Pain Unpleasantness More activity in IFG and amygdalae Strong effect Less activity in IFG and amygdalae No effect explains 58% variability explains 34% variability dlPFC, dorsolateral prefrontal cortex; IFG, inferior frontal gyrus; OFC, orbitofrontal cortex

41 How we can help ? Depressed patients seen in primary care Increase Awareness Better identification Proper & early treatment for Neuropathic Pain Proper & early treatment for Depression/anxiety Increase Awareness Better identification Proper & early treatment for Neuropathic Pain Proper & early treatment for Depression/anxiety

42 Treatment for Neuropathic Pain Treatment / control of cause Alternative treatments (TENS, Acupuncture) Pharmacotherapy: –NSAID / Pain Killers –SNRIs / TCA –Anti-epileptics –Alpha 2 Delta agonists –Opiate Based preparation !! TMS Epidural blocks Implantable drug pumps Neurostimulation surgical interventions Psychological: CBT for Pain

43 Risk of iatrogenic addiction in patients treated with opioids A systematic review 41 studies with conflicting findings Risk can be relatively high (>10%) or low ( 10%) or low (<0.1%). [1] A systematic review noted the prevalence of [2] –Lifetime SUD 36% to 56% –Current SUD 43% –Aberrant medication-taking behaviours 5% to 24% [1] Wasan et al [2] Martell et al 2007 Risk factors for opioid abuse in patients with chronic pain are [3] : young age, male gender, past alcohol or cocaine abuse, previous drug conviction, mental health disorders, pain in multiple regions, pain after MVA [3] Højsted & Sjøgren

44 Opioid treatment; may need a revisit A large population-based study found that opioid usage was significantly associated with: more severe pain, poorer self-rated health, lower quality of life, less physical activity, lower employment, higher levels of health care utilization, and more subjects living alone impaired neuropsychological performance reaction times, psychomotor speed, and working memory Højsted & Sjøgren Curr Opin Anaesthesiol Oct;20(5):451-5.

47 Greco T et al. J Gen Intern Med 2004; 19: Depressive symptoms Positive well being Non painful Somatic symptoms Painful Somatic symptoms Painful Somatic symptoms may be less responsive to treatment relative to other symptoms The challenge in treatment

48 Depressive symptoms Painful symptoms are associated with worse depression outcome the ARTIST Trial Depression outcome at 6 month for n=573 Treated in primary care DeVeaugh-Geiss ey al Pain Medicine 2010; 11: 732– (80%) have pain 190 (33%) mild pain 165 (29%) moderate pain 103 (18%) severe pain Around 60% adequate treatment was given

49 Proper identification & early treatment for Depression Pharmacotherapy: –SNRIs / TCA –Mood stabilizers (CBZ) –Alpha 2 Delta agonists (pregabalin / Gabalin) –BZD –Pipe Lines: NMDA Antagonists Somatic Treatment: TMS Psychosocial: CBT for Depression, social inclusion & re-habitation How to achieve recovery?

50 Pooled data from Thase et al & Nemerrof et al What Antidepressant to Use?

51 What Antidepressant to Use in painful depression?

52 What SNRI to use in Painful Anxiety & Depression? Duloxetine & Venlafaxine are both effective…. Perahia D et al.

57 PsychologicalUses BehaviouralIncrease exercise/activity levels; overcome fear– avoidance Cognitive- behavioural Reduce depression and anxiety associated with pain; develop effective coping strategies; reduce problematic cognitive styles. InterpersonalAddress role transitions due to pain; relationship difficulties/conflicts Adjunctive techniques BiofeedbackMuscle relaxation; control of physiological parameters contributing to pain (e.g., headache) Guided imageryRelaxation; distraction from pain HypnosisRelaxation; pain severity reduction; distraction Progressive muscle relaxation Muscle relaxation; distraction from pain What other interventions to use?

58 Despite the frequent coexistence of depression, anxiety and pain the magnitude and implications of that relationship are still unclear. Neglecting the treatment of fatigue, low energy, and painful physical symptoms in depressed patients can lead to unsatisfactory outcomes, characterized by a failure of depressed patients to return to normal social and occupational functioning.Conclusion: Keller MB et al 1992, Judd LL et all 1998, Angst J 1992and Kupfer DJ 1991; Sheline YI et al 1996; Blier P et al. 2001
