Integrative Therapies in the Treatment of Depression and Mood Disorders Dr. James M. Greenblatt, M.D. September 29, 2007
Integrative Medicine • Integrating the best of conventional medicine and evidence base complementary therapies emphasizing patient participation in health promotion, disease prevention and medical management. • “It might be too pretentious to say that such a growth at integrative medicine might restore the soul to medicine – the soul being that part of us that is the most important but the least easy to deliniate.” British Journal of Medicine 2001
Why is Psychiatry Different? • Medical treatment for mental disorders differs from treatment of all other medical specialties. • Psychiatrists typically do not use objective measurements to guide treatment of mental or addictive illness
Medical Testing includes • Blood, Urine, Saliva Assays • Microbiology • Tissue analysis • X-Ray, MRI, CT Scans, PET Scans • EKGs, EEGs • ETC…
Diagnosis and Treatment General Medical Treatment: Symptoms Measure Physiology “Anti”-physiology treatment Measure physiology and symptoms Psychiatric Treatment: Symptoms “Anti”-Symptom treatment given Measure symptoms
The “Art” of Psychopharmacology • Heterogeneity of medication response, • One class of medication treats multiple disorders • SSRI’s: • Panic Disorder • Generalized Anxiety • Social Phobia • “No name distress” • PMPD • SAD • MDD • Bulimia
Response to Psychopharmacologic Treatment • 50% improvement of the primary symptoms of depression is the standard measure of treatment response • 20-40% do not show substantial clinical improvement • 50% who show improvement have residual symptoms that impact functioning
Factors Associated with Insufficient Symptom Improvement Following an Adequate Trial of Antidepressants Partial or Non-Response
Nutrition and Health Understanding the role of Nutrition and Health is not Alternative Medicine
Nutrient Deficiencies Are Common Percentages of U.S. Population Not Meeting the DRI For Specific Nutrients Variability in Individual Nutrient Needs are Established
Medicine and Nutrition Medical Profession’s reluctance to change • Folic Acid • 25+ years • Aspirin • 15+ years
Neurotransmitters • At least 250 are known • Release of these chemicals causes electrical impulses throughout the brain resulting in: • Thoughts • Feelings • Behaviors • Neurotransmitter levels affect every facet of a biological system
All psychotropic medications effect levels of neurotransmitters in the brain
Neurotransmitters • Most neurotransmitters are under precursor control • Precursors are substances obtained in whole or part from our diet • Precursors are most easily obtained from meats and animal products
Folic Acid Vitamin B6 Vitamin B12 Vitamin C Vitamin D Vitamin B3 Neurotransmitter Synthesis L-Tryptophan 5-HTP ST L-Tyrosine L-Dopa DA NE Epi • Magnesium • Zinc • Iron • Copper
Neurotransmitters What causes Neurotransmitter Deficiencies? • Genes • Diet • Stress • Neurotoxins
Increasing Tryptophan in Diet Decreasing Tryptophan in Diet Increases Serotonin in the brain Decreases Serotonin in the brain Neurotransmitter Precursors In any normal diet animal based or vegetarian Tryptophan is the least plentiful of all 20 amino acids (9:1)
Tryptophan Supplementation Induces a Positive Bias in the Processing of Emotional Material in Healthy Female Volunteers Psychopharmacology July 2006 • 38 healthy female volunteers • 14 day DBPCT with 1 gm Tryptophan 3 times a days placebo • Tryptophan supplementation resulted in a positive bias in processing emotional material in women
Tryptophan boosts confidence and reduces aggression • 1 mg Tryptophan 3 X/day • 12 day DBPCT • Tryptophan increased agreeable behavior • and reduced quarrelsome behavior
Tryptophan • 1989, The FDA removed tryptophan due to outbreak of Eosinaphilia Myolgia (EMS) • Traced to a single batch of contaminated tryptophan from Japan
Folic Acid Vitamin B6 Vitamin B12 Vitamin C Vitamin D Vitamin B3 Neurotransmitter Synthesis L-Tryptophan 5-HTP ST L-Tyrosine L-Dopa DA NE Epi • Magnesium • Zinc • Iron • Copper
5-Hydroxytryptophan (5-HTP) • Direct precursor to serotonin • Extracted from the seeds of the Giffonia plant • Not produced by bacterial fermenatis
5-HTP A guided missile directly targets increased brain serotonin levels
5-HTP • Converted from Tryptophan with a vitamin B3dependent enzyme • Converted to serotonin with a vitamin B6dependent enzyme • Easily crosses blood brain barrier • Not incorporated into proteins • Not utilized to make vitamin B3 • Response usually less than two weeks
5-HTP 50-300 mg/day Empty stomach best Divided 2-4 does Start low and titrate dose Tryptophan 500-3000 mg/day Empty stomach best Divided 2-4 doses Clinical Applications Recommended Dosages:
Folic Acid Vitamin B6 Vitamin B12 Vitamin C Vitamin D Vitamin B3 Neurotransmitter Synthesis L-Tryptophan 5-HTP ST L-Tyrosine L-Dopa DA NE Epi • Magnesium • Zinc • Iron • Copper
Folic Acid and SAMe • The folate cycle synthesizes methyl groups, which are then used by SAMe in numerous methylation reactions including: Neurotransmitters synthesis
Folate and Depression • 11 relevant studies (15,315 participants, 3 case-control studies, 7 population surveys, and 1 cohort study) were systematically analyzed • A significant correlation between folate levels and depression – low folate status is linked to depression Gilbody et al. J Epidemiol Community Health 2007
Folate Deficiency and Depression • ≥ 56% of patients with affective disorders had folate deficiency • Lower serum folate concentrations are correlated with greater severity of depression • Red blood cell folate levels are significantly lower in depressive patients than those suffering from other psychiatric disorders
Causes of Folate Deficiency States • Inadequate intake: Dietary sources heat labile, easily oxidized (≥ 50% during food shortage and processing) • Malabsorption • Genetic polymorphism • Medications
Anticonvulsants (phenytoin, primidone, phenobarbital, carbamazepine) Oral contraceptives Sulfsalazine Methotrexate Triamterene Pyrmethamine Trimethoprim Alcohol Antacids Antibiotics Metformin Drugs that Can Cause Folate Deficiency States
Folate and Antidepressant Response • Folate deficiency may hinder antidepressant response to standard antidepressants - 213 adults (ages 18-65) with Major Depressive Disorder (MDD) treated with fluoxetine 20mg qd x 8 weeks • Low folate correlated with melancholia and lack of response • No correlation of levels and lack of appetite or weight loss
Enhancement of the antidepressant action of fluoxetine by folic acid: a randomized, placebo controlled trial Alec Coppen, John Bailey Journal of Affective Disorder 60 (2000) 121-130 • Effective augmentation study of Prozac: • Placebo controlled study • 500 mcg/day • Effective in women, not men “Folic acid is a simple method of greatly improving the antidepressant action of fluoxetine and probably other antidepressant agents.”
Folate Augmentation in First Episode Depression* • Double blind trial of 127 patients experiencing their first episode of depression. Patients randomized to receive either 20mg fluoxetine + 500mcg folate or 20mg fluoxetine + placebo. • Treatment with fluoxetine augmented with folate resulted in a significantly greater improvement in depression compared to fluoxetine alone. Folate treatment resulted in greater remission rates over placebo among women but not men with depression. • No additional adverse events were reported with the addition of folate. Percentage of women who achieved HAM-D <9 Percentage of Reported Side Effects * Coppen, Alec, Journal of Affective Disorders, 2000; 60:121-130.
Folate and Relapse • After 28 weeks of fluoxetine treatment, (71 pts) 20mg/day: • Relapse rate for patients with low folate levels (< 2.5ng/mL) was 42.9% • While relapse rate for patients with normal folate levels was only 3.2% Please Read This Again Papakostas et al, J Clin Psychiatry, 2004; 65: 1096-1098
102 geriatric psychiatric inpatients Lower levels of folate and B12 predicted poorer cognitive status Lower levels of folate predicted a longer psychiatric hospitalization Severity of psychiatric illness correlated with lower folate levels Folate and Severity of Illness 15 Bell IR; Edman et al, Biological Psychiatry, 1990;15, 27(2):125-37.
Folic Acid and the Treatment of Depression • Low folate associated with increased incidence of depression • Low folate associated with poor response to antidepressants • Low folate associated with higher relapse rate • Folate supplementation enhances effect of Antidepressants
Folic Acid Supplementation in Depression “We suggest the use of 2mg of folic acid, which would be expected to increase plasma folate to more than 20ng/mL in both sexes…Adding 2mg of folic acid to antidepressant treatment would be easy in everyday clinical practice. The daily supplement could be easily taken. It is inexpensive and safe.” Abou-Saleh & Coppen, J Psychosom Res 2006
Folic Acid Supplements • Folic Acid: • Folinic Acid • Folinic Acid (Leucovorin) • L-Methylfolate (Deplin)
Folic Acid Conversion to L-methylfolate • Folic acid requires a 4 step transformation process to be converted to the active form of folate, L-methylfolate. Dietary folate requires 3-steps. • L-methylfolate is absorbed directly in the active form that can immediately cross the blood brain barrier for use. • L-methylfolate is unaffected by the CT polymorphism.
MTHFR Polymorphisms • Polymorphisms in the gene coding for methylenetetrahydrofolate reductase (MTHFR) reduce efficiency of folic acid metabolism • Polymorphisms increase risk of depression • Patients who have MTFR CT genotypes have a 1.36 times greater chance of developing depression • The odds of having the T/T genotype is twice as great in depressed patients verses the normal population
The odds of having the T/T genotype is twice as great in depressed patients verses the normal population.1,4 Deplin, not Folic Acid, bypasses a common genetic mutation present in the majority of patients with MDD Prevalence of C→T Polymorphism in the Depressed Population1 • Allelic frequency of the C/T-T/T mutation is 70% in the depressed population.1 • Patients who have the MTHFR C→T genotypes have a 1.36 times greater chance of developing depression (and reported as high as 4 times the general population).2,3 1.

How Deplin Differs from Folic Acid • Folic acid requires a 4 step transformation process to be converted to the active form of folate, L-methylfolate. Dietary folate requires 3-steps • L-methylfolate is absorbed directly in the active form that can immediately cross the blood brain barrier for use. • L-methylfolate is unaffected by the CT polymorphism 20
