  3. 3. The Mind & The Body When DESCARTES uttered his famous dictum “cogito ergo sum ” which separated mind from body, he did medicine a favour Now, however, the idea that mind & body are separate is holding medicine back from fully exploring the interactions among mind, body & brain The idea constrains our knowledge of how depression & anxiety complicate illness such as diabetes, heart disease, cancer etc.
  4. 4.  It also obscures the obvious fact that medical treatment must encompass CARE AS WELL AS CURE – involve the person with the illness & not just the disease in the body Our bodies are merely the structures which house the mind. “MIND” is the controlling power & so we must keep it healthy to the maximum extent possible “We can’t think of a healthy body without a healthy mind”
  5. 5. “It is much more important to know what sort of a patient has a disease than what sort of disease a patient has” - Sir William Osler (1849-1919)
  6. 6. Depression is a disorder of mood/feeling- That is unpleasant There is feeling of sadness Misery Which affects day to day activities of life
  7. 7.  Depression for psychiatrist is what “common cold” is for physicians! Lifetime prevalence - 10% for males & 20% for females Point prevalence - 5% for males & 10% for females.

  16. 16. A. Psychological Symptoms Low mood Loss of drive, energy & interest Poor Concentration Tearfulness Irritability Apprehensive attitude Guilt feeling Suicidal ideas
  17. 17. B. Somatic Symptoms Dejected look Psychomotor retardation Insomnia Weight loss Musculo-Skeletal pains Headache G.I. disturbances- gastric fullness Cardiovascular symptoms- palpitations
  18. 18. C. Social Symptoms Decreased social interaction Poor work performance Decline in problem solving ability Neglect of family & friends Social Withdrawal
  19. 19.  Depression is frequently undiagnosed & untreated in medical & primary care setting despite its frequency, negative effect on health & treatability
  20. 20. CAUSES of missing diagnosis of MDD in general clinical practice:- Lack of time-Most medical visits last less than 15 min. & lot many issues are addressed in this brief time Lack of privacy in medical setting limits disclosure or elaboration of symptoms Lack of time & skill on part of clinician to manage emotionality which may be triggered after touching an emotional issue Pt’s may not recognize depressive symptoms & may attribute them to their medical condition (as many symptoms of Depression are similar to those of medical illness)
  21. 21.  Missing diagnosis of MDD in medical setting may result in Lost opportunity to: -Improve quality of life -Decrease risk of suicide -Shortened hospital stay -Improved treatment compliance
  22. 22. NEED FOR A SCREENING INSTRUMENT Lloyd Williams et. al found that asking patients in a palliative care unit a single question “are you depressed” with a response choice of “yes” or “no” yielded a sensitivity of only 55% & specificity of 74% for diagnosis of MDD
  23. 23.  So there is a need for accurate & rapid methods of screening for Depression in medical settings Screening instruments most widely used:1.Center for Epidemiologic Studies Depression Scale (CES-D)2.Hospital Anxiety & Depression Scale(HADS)3.Beck Depression Inventory-II (BDI-II)4.Patient Health Questionairre-9 (PHQ-9), this is self administered version of PRIME-MD
  24. 24.  There is overlap b/w symptoms of depression & constitutional symptoms of med illness (anorexia, fatigue, weight loss, insomnia, psychomotor retardation & diminished concentration) Different approaches have been proposed to overcome difficulties due to this overlap:-1. Inclusive approach2. Exclusive approach3. Etiologic approach4. Substitutive approach
  25. 25. 1) Inclusive approach:- -includes all symptoms of depression, regardless of their cause -High rate of false positives2) Exclusive approach:- -Simply excludes all the overlapping symptoms -Low sensitivity3) Etiologic approach:- -requires clinicians to determine causality and reject symptoms when they are “clearly due to a physical condition” -Difficult to administer
  26. 26. 4) Substitutive approach (Endicott’s criteria):- -Suggests replacing of Physical symptoms with Psychological symptoms -Studies have found this to be both reliable & valid Endicott’s criteriaDSM-IV criteria Substitutive criteriaAppetite disturbance Depressed appearanceSleep disturbance Social withdrawalLoss of energy Self-Pity or PessimismDifficulty in concentrating Non-reactive mood
  27. 27. Depression & CVD CVD DEPRESSION
  29. 29.  Major depressive disorder ◦ Present in as many as 20% patients with CAD More than 3 out of 4 individuals with immediate post-MI depression are still depressed 3 months later Ziegelstien R JAMA 2001;286:1621-1627 Taylor D. Acta Psychiatr Scand 2008; 118: 434
  30. 30.  Depression associated with 64% ↑ risk for CAD  Anger/hostility associated with: ◦ 20% ↑ risk incident CAD in initially healthy individuals ◦ Poor prognosis in CAD patients  Relative risk of developing CAD in patients with depression as compared to general population: ◦ 1.81 (95% CI: 1.53 – 2.15)  Relative risk of death due to cardiovascular events: ◦ 1.80 (95% CI: 1.5–2.15)Taylor D. Acta Psychiatr Scand 2008; 118: 434.
  31. 31.  Thus, there is an established association between: ◦ Depression & development of CAD (Depression is an independent risk factor for heart disease) ◦ Depression & cardiovascular mortality (Depression is an imp. independent predictor of death even after CABG)Taylor D. Acta Psychiatr Scand 2008; 118: 434.
  32. 32. Depression as a Risk Factor
  33. 33. Depression as a Risk Factor
  34. 34.  Increased morbidity and mortality Significant risk factor for stroke, myocardial infarction (MI), and death in elderly hypertensive patients Four times higher rates of cardiac mortality in patients with acute MI Lack of motivation to initiate & sustain heart-healthy lifestyle changes (such as smoking cessation, modification of diet & an exercise program) Poor prognosis in CAD disease

Correlation Between Depression and Diabetes Mellitus Increased release of counter-regulatory hormones Depression Catecholamines Glucocorticoids Glucagon Growth Hormone Decreased action of insulin Increased blood & Increased insulin resistance glucose levels Depression associated insulin resistance (DAIR) • Could double the risk of type 2 diabetesDL Musselman et al., Bio Psychiatry 2003; 54:317-329. • may increase the risk of CADPatrick J. Lustman & Ray E, Journal of Psychosomatic • may increase diabetic complicationsResearch 53 (2002) 917-924.
  42. 42.  Higher risk of depression in diabetic patient who ◦ Have less education ◦ Unmarried ◦ Poor social support ◦ Experience chronic stressors Young women with diabetes had up to nine times risk for depression than their male counterpart Adolescent with diabetes have up to three fold greater chance of depression, than youth without diabetes Children with diabetes have two fold greater prevalence of depression
  43. 43.  Altered cerebral glucose utilization is seen in left lateral prefrontal cortex & it shows correlation with severity of depressive symptoms Diabetic pts have higher pro-inflammatory cytokines (Il-6) released by adipose tissue, monocytes & macrophages – ◦ Interfere with insulin action ◦ Induce sickness behavior including fatigue, anorexia, anhedonia, decreased psychomotor activity etc. Stress & neuroendocrine mediators influence hippocampal neuronal plasticity  depressive symp.

  54. 54.  No TCA should be used, as consequences of their use ( HR, risk of orthostatic hypotension, and  PR & QTc prolongation) may be fatal  The only antidepressants shown to be safe and effective in post-MI patients are SSRI’s (Sertraline,Escitalopram,fluoxetine,paroxetine)Goodnick PJ, Hernandez M. Expert Opin Pharmacother 2000; 1: 1367-1384.
  55. 55. Context:  MDD occurs in 15% to 23% of patients with acute coronary syndromes  Constitutes an independent risk factor for morbidity and mortality  No published evidence exists that antidepressant drugs are safe or efficacious in patients with unstable IHD Objective:  To evaluate the safety and efficacy of sertraline for the treatment of MDD in patients hospitalized for acute MI or unstable angina and free of other life-threatening medical conditionsGlassman AH, et al; JAMA 2002
  56. 56. Sertraline was safe and well-tolerated  Sertraline treatment was not associated with any significant change in » Blood pressure » Heart rate » Arrhythmias » ECG parameters  Incidence of severe CV events was numerically lower among patients receiving sertraline (14.5% vs 22.4%)Glassman AH, et al; JAMA 2002
  57. 57.  While treating CAD, look for co morbid Depression Detect Depression and treat it at the earliest All patients with depression should be advised to take steps to reduce behaviors associated with CA disease TCAs should be avoided in patients with/at risk of CAD SSRIs (Sertraline) are the Drug of choice for Depression & Co-morbid CAD Treatment of depressive symptoms improves medication adherence in patients after AMI Better outcome for CAD if Depression is treated effectively
  58. 58.  All patients with a diagnosis of depression should be screened for diabetes In those who are diabetic- Use SSRIs first line; most data support fluoxetine & sertraline. SNRIs are also likely to be safe but there are fewer supporting data Avoid TCAs and MAOIs if possible due to their effects on weight and glucose homeostasis Monitor blood glucose carefully when antidepressant treatment is initiated, when the dose is changed and after discontinuation -Maudsley Prescribing Guidelines 10th edition
  59. 59. B. SSRIs Doses1. Sertraline 50–200 mg/day2. Citalopam 20–60 mg/day3. Escitalopam 10–30 mg/day4. Fluoxetine 20-60 mg/day5. Fluvoxamine 100–300 mg/day6. Paroxetine 20–50 mg/day
  60. 60.  Depression is a disorder of mood/feeling & it would be 2nd largest cause of DALY by the year 2020 Frequently associated with other major medical/surgical illnesses Cases are usually missed due to misconceptions & misidentifications Overlap of somatic symptoms makes accurate diagnosis difficult Depression is a disorder that needs to be treated simultaneously Depression & CAD as well as Depression & DM have bidirectional relationship
  61. 61.  SSRIs are the “drug of choice” Treatment should be started as early as possible ◦ Not only to get relief from psychological symptoms ◦ But also to avoid complications or achieve cure of physical illness
