PEDIATRIC AND ADOLESCENT DEPRESSION DIAGNOSIS AND TREATMENT ANTOINETTE FALK, M.D. Solo Private Practice Psychiatry COURSE OBJECTIVES To identify the unique manifestations of depression in adolescents, as opposed to those seen in adults To know the medical and psychiatric comorbidities of untreated depression To become familiar with proper treatment approaches and modalities in treating depression To understand and appreciated the need for early intervention and neuroprotection. HISTORICAL PERSPECTIVE Depression (melancholia) in childhood reported in 1800’s Prior to 1960’s, believed that depression could not develop due to immature superego construction. In 1970 an international congress concluded childhood depression to be significant MAJOR DEPRESSIVE EPISODE DSM-IV CRITERIA Presence of 5 symptoms during the same 2 week period: Depressed or irritable mood Diminished interest or loss of pleasure in almost all activities (Anhedonia) Sleep disturbance – initial, middle or terminal insomnia Weight change or appetite disturbance (failure to achieve expected weight gain or 5% loss of body weight in 1 month) MAJOR DEPRESSIVE EPISODE DSM-IV CRITERIA - CONTINUED Decreased concentration or indecisiveness Suicidal ideation or thoughts of death Psychomotor agitation or retardation Fatigue or loss of energy Feelings of worthlessness or inappropriate guilt Psychotic features may or may not be present MAJOR DEPRESSIVE EPISODE DSM-IV CRITERIA - CONTINUED Other features: A quality of depressed mood that is distinctly different from the kind felt when a loved one is lost or deceased Depression is worse in the morning (Diurnal Mood Variation) Waking up 2 hours earlier than usual DYSTHYMIA DSM-IV CRITERIA Depressed or irritable mood lasts at least one year and is never symptom free for more than 2 months; in addition, two of the following must be present: Appetite change Sleep change Decreased energy DYSTHYMIA DSM-IV CRITERIA - CONTINUED Low self-esteem Difficulty making decisions or poor concentration Feelings of hopelessness ATYPICAL DEPRESSION DSM-IV CRITERIA Mood reactivity Increase in appetite or significant weight gain Increased sleep Feelings of heaviness in arms or legs A pattern of long-standing rejection sensitivity that extends far beyond the mood disturbance episodes and is significantly impairing BIPOLAR DEPRESSION Presents similarly to unipolar depression except more likely to include the following: atypical depression (BORDERLINES) explosiveness with minimal or no external provocation (BORDERLINES) pharmacologically induced hypomania (hypomania induced by medications) family hx of bipolar disorder SEASONAL AFFECTIVE DISORDER Although there is minimal literature in pediatrics, data suggests the possibility of SAD in adolescent and prepubescent populations living in climates with distinct seasonal change Difficult to distinguish from school related cycles Some literature support the benefits of phototherapy ADJUSTMENT DISORDER Excessive change in mood and impairment of functioning within 3 months of a significant stressor Self limited in duration Less severe mood disturbance and fewer symptoms than major depression PREMENSTRUAL DYSPHORIC DISORDER In brief, mood symptoms which may include Anxiety Irritability depression, mood lability occurring in the last week of the luteal phase and remitting within a few days of the follicular stage. The disturbance significantly interferes with school, work, relationships or social activities and is not better accounted for by another disorder. SYMPTOMS OF MAJOR DEPRESSIVE DISORDER COMMON TO ADULTS, CHILDREN, AND ADOLESCENTS Persistent sad or irritable mood Loss of interest in activities once enjoyed Significant change in appetite or body weight Difficulty sleeping or oversleeping Psychomotor agitation or retardation SYMPTOMS OF MAJOR DEPRESSIVE DISORDER COMMON TO ADULTS, CHILDREN, AND ADOLESCENTS – CONTINUED Loss of energy Feelings of worthlessness or inappropriate guilt Difficulty concentrating Recurrent thoughts of death or suicide AGE RELATED SYMPTOM DIFFERENCES Depression in children is more frequently manifested by Separation anxiety Phobias Somatic complaints (stomachaches, headaches) Behavioral problems. AGE RELATED SYMPTOM DIFFERENCES – CONTINUED Older children and adolescents are more likely to manifest Sadness Psychosis Suicide attempts Acting out Substance abuse Increased lethality of suicide attempts Impaired functioning SIGNS THAT MAY BE ASSOCIATED WITH DEPRESSION IN CHILDREN AND ADOLESCENTS Frequent vague, non-specific physical complaints such as headaches, muscle aches, stomachaches or fatigue Frequent absences from school or poor performance in school Talk of or efforts to run away from home Outbursts of shouting, complaining, unexplained irritability, or crying SIGNS THAT MAY BE ASSOCIATED WITH DEPRESSION IN CHILDREN AND ADOLESCENTS – CONTINUED Being bored Lack of interest in playing with friends Alcohol or substance abuse Social isolation, poor communication Fear of death SIGNS THAT MAY BE ASSOCIATED WITH DEPRESSION IN CHILDREN AND ADOLESCENTS – CONTINUED Extreme sensitivity to rejection or failure Increased Reckless irritability, anger, or hostility behavior Difficulty with relationships CONDITIONS THAT MIMIC DEPRESSION mononucleosis influenza encephalitis subacute bacterial endocarditis tuberculosis hepatitis CNS syphilis AIDS pneumonia CONDITIONS THAT MIMIC DEPRESSION – CONTINUED seizure disorders postconcussion subarrachnoid hemorrhage Cerebrovascular accident multiple sclerosis Huntington’s disease diabetes Cushing’sdisease Addison’s disease hypothyroidism hyperthyroidism hyperparathyroidism hypopituitarism CONDITIONS THAT MIMIC DEPRESSION – CONTINUED substance abuse and withdrawal: alcohol, cocaine, amphetamines, opiates hypokalemia hyponatremia failure to thrive anemia uremia chronic fatigue syndrome fibromyalgia porphyria Wilson’s disease lupus DEPRESSION INDUCING MEDICATIONS antihypertensives barbiturates corticosteroids oral contraceptives cimetidine aminophylline oral smoking cessation medication (Chantix) anticonvulsants clonidine and guanfacine digitalis thiazide diuretics psychostimulants oral anti-acne medication (Accutane) EPIDEMIOLOGY Major depression prevalence: 2% childrenwith 1:1 female: male ratio, 8% in adolescents with higher 2:1 to 4:1 female:male ratio cumulative incidence by age 18 is 20% Dysthymia prevalence: 0.6 to 1.7% children; 1.6 to 8 % in adolescents 20 to 40% of adolescents with major depression will develop Bipolar disorder within 5 years ASIAN AMERICANS Chinese, Filipino, Korean and Japanese immigrants consistently report higher numbers of depressive symptoms than Caucasians Asian Americans have the lowest utilization for mental health services and are more likely to have psychotic diagnoses in inpatient and outpatient settings. Studies further show that Asian Americans have greater disturbance levels than do non-Asian clients ASIAN AMERICANS 71% of Southeast Asians meet the criteria for a Major Affective Disorder (which includes depression) Hmong (85%) and Cambodians (81%) showing the highest rates. Moreover, 70% of Southeast Asian refugees are found to have post-traumatic stress disorder ASIAN AMERICAN TEENS Among women aged 15 – 24: Asian American adolescent girls have the highest suicide mortality rates across all racial/ethnic groups. And the highest rates of depressive symptoms of all racial/ethnic and gender groups. ASIAN AMERICAN TEENS – CONTINUED Asian American college students report higher levels of depressive symptoms than white students. Asian American adolescent boys are twice as likely as whites to have been physically abused, and three times as likely to report that they have been sexual abused SUSTAINED IRRITABILITY IN CHILDREN: MAY BE AN INDICATOR OF BIPOLARITY Leibenluft, Charney, et al (two studies done 2003, 2006): Irritability (a mood state characterised by anger and easy annoyance) which is continually present at a very young age (often from the first year of life) should be considered the typical mood of early mania.

BIOLOGICAL MARKERS Hypersecretion of corticotropin-releasing factor Dexamethasone nonsuppression of cortisol Hyposecretion of growth hormone in response to insulin challenge and hypersecretion during sleep Decreased levels of norepinephrine and serotonin (risk for suicide) metabolites in CSF BIOLOGICAL MARKERS – CONTINUED Various sleep study results show decreased REM latency increased REM density decreased sleep efficiency GRAY MATTER LOSS THE NEED FOR NEUROPROTECTION EFFECTS OF DEPRESSION ON THE BRAIN: HIPPOCAMPUS Imaging: Hippocampal size decreases in patients with Depression and PTSD Depression: nerve cells/appendages become depleted of serotonin and “shrink”, thereby reducing their ability to communicate with each other TREATMENT CAN IMPROVE (reverse) THIS ABNORMALITY IN THE SIZE OF THE HIPPOCAMPUS BY WAY OF NEUROGENESIS (creation of new nerve pathways) REMISSION MAY PROTECT THE BRAIN FROM LONG-TERM DEPRESSION RELATED CHANGES Frodi TS et al Arch. Gen Psychiatry 2008; 65 (10): 1156-1165 Prospective, Longitudinal Study : 38 participants with MDD/Depression and 30 controls were followed for 3 years. Brain Morphometry was assessed by MRI REMISSION MAY PROTECT THE BRAIN FROM LONG-TERM DEPRESSION RELATED CHANGES RESULTS Patients with MDD/Depression who went into remission showed significantly less volume reduction in brain areas of direct relevance to the pathophysiology of MDD (VM prefrontal cortex, hippocampus, amygdala) Patients with MDD/Depression who did not achieve remission showed more volume reduction in brain areas of direct relevance to the pathophysiology of MDD PATIENTS WITH DEPRESSION (MDD) WHO DID NOT RESPOND TO ANTIDEPRESSANTS HAD HIGHER INFLAMMATORY CYTOKINE LEVELS 2007: O’Brien SM et al, (J. Psychiatr Res; 41: 326-331) 24 Healthy Controls and 28 patients with Depression (HAM D >20, after 6 weeks of treatment with SSRI’s ) and 16 euthymic patients (previously resistant to SSRI’s and currently successfully treated with SNRI’s or SSRI’s + the mood stabilizer Lithium PATIENTS WITH DEPRESSION (MDD) WHO DID NOT RESPOND TO ANTIDEPRESSANTS HAD HIGHER INFLAMMATORY CYTOKINE LEVELS – RESULTS TNFα (pg/ml) – averages 12 pg/ml – Controls 20 pg/ml – Depressed 8 pg/ml – Euthymic p=0.004 IL6 (pg/ml) – averages 0.9 pg/ml – Controls 1.2 pg/ml – Depressed 0.8pg/ml – Euthymic p=0.01 INFLAMMATORY CYTOKINE ACTIVITY INCREASE Inflammation gone wild means increased risk : Cardiovascular Events Stroke Metabolic Syndrome, including Diabetes Mellitus Heart Disease HPN Infection Tissue Trauma Neoplasm PSYCHOLOGICAL MODELS FOR DEPRESSION Psychoanalytic: Real or imaginary loss of a loved object with “anger turned inwards”. Learned helplessness: Behavior is independent of, or lacks reinforcers, thus one gives-up in trying to change condition. PSYCHOLOGICAL MODELS CONTINUED Life Stress: Inability to adjust to changes/stressors leads to depression. Behavioral Reinforcement: Inadequate or insufficient positive reinforcers contribute to depression. PSYCHOLOGICAL MODELS CONTINUED Self Control: Deficits in selfreinforcement, self-evaluation and selfmonitoring result in depression. Misattribute success to external factors and failure to personal factors. PSYCHOLOGICAL MODELS CONTINUED Cognitive Distortion: The triad – personal life and the world are terrible (negative personal/world view) nothing can be done to change this (helplessness) the future holds more of the same (hopelessness). CLINICAL COURSE Episode Duration: Major depression 7 to 9 months dysthymia 3 to 4 years Relapse rates: major depression are 20 to 60% in the first 1 to 2 years of remission 70 % after 5 years of remission First episode of major depression usually occurs 2 to 3 years after the onset of dysthymia CLINICAL COURSE Untreated, major depression and dysthymia affect a child’s development of social, emotional, cognitive and interpersonal skills and attachment relationships. Treatment delay averages 10 years There are high risks of suicidal behaviors, substance abuse, medical illness, early pregnancy, exposure to negative life events and impaired academic and vocational functioning.

PSYCHOTHERAPIES - CONTINUED Behavioral Therapy: Response contingent positive reinforcement Focus on skills especially interpersonal skills which can be reinforced. Frequently paired with cognitive therapy PSYCHOTHERAPIES - CONTINUED Insight oriented: Starts with supportive, moves to empathy, then collaboration/self observing Therapists gives interpretations of anxiety and affect May go from current relationships to past relationships (looking back to move forward) Transference interpretations may be made PSYCHOTHERAPIES - CONTINUED Life Stress: -Focus is on Resolving • modifying or • accepting the stressor. • PSYCHOTHERAPIES - CONTINUED Cognitive: • -Therapist aids in correcting cognitive distortions via persuasion challenging cognitions examining evidence exploring alternative explanations, assessing consequences -Therapists must be creative, cognitively flexible, and energetic. PSYCHOTHERAPIES - CONTINUED Group: Many of the aforementioned therapies can occur in group settings with proper planning and structure and adequate number of therapists. PSYCHOTHERAPIES - CONTINUED Family Therapy -dynamics of relationships may need to change i.e. increase affection increase communication -clarify roles and reduce role diffusion -moderate rigid or chaotic rule structures -therapist will need specific training PHARMACOTHERAPY Evidence for efficacy in childhood mood disorders is less than evidence for adult disorders High rate of placebo response Open trials show efficacy Antidepressants are used widely in children due to significant morbidity of the disorder 7% of total antidepressants prescribed in 2002 were for pediatric population Suggested approaches are based on data from adult studies, as well as anecdotal, clinical, and research experience PHARMACOTHERAPY SSRI’s Escitalopram (Lexapro) 2.5-20mg/day Citalopram (Celexa) 5-60mg/day Sertraline (Zoloft) 12.5-200mg /day Paroxetine (Paxil/Paxil CR) 5-60mg/day Fluvoxamine (Luvox) 25-300mg/day, divided Fluoxetine (Prozac) 2.5-80mg/day PHARMACOTHERAPY Buproprion (Wellbutrin/SR/XL) 100-450 mg/day Contraindicated with seizures Venlafaxine (Effexor/XR) 37.5-225 mg/day Mirtazepine (Remeron) 7.5-45 mg/day Tricyclics (Nortriptylline, Desipramine, Imipramine, Elavil, Anafranil) – monitor QT interval, levels MAO Inhibitors – rarely used because of dietary restrictions, drug interactions Benzodiazepines – short term for anxiety PHARMACOTHERAPY -- CONTINUED When Bipolar Depression is suspected, always use a mood stabilizer even when the patient is depressed. Properly wean off antidepressant when Mania or Hypomania emerges 33% of Bipolar patients are susceptible to antidepressant-induced mania, mood acceleration, mood destabilization. ALGORITHM Start with an SSRI. If needed, take to maximum as tolerated Change to another SSRI Try different class of antidepressant Augmentation Another antidepressant Lithium, Valproate, Lamotrigine, Tegretol (mood stabilizers) Atypical antipsychotics (can help stabilize mood) Benzodiazepines Thyroid augmentation ALGORITHM – REMEMBER: When Bipolar Depression is suspected, always use a mood stabilizer even when the patient is depressed. Properly wean off antidepressant when Mania or Hypomania Or when depression worsens or suicidal ideation emerge as antidepressants are being administered. Because in 33% of Bipolar patients, antidepressants c can induce mood destabilization, mania, or mood acceleration. LENGTH OF TREATMENT First Episode – 9-12 months Two episodes – minimum two years Three episodes – five years to life PHARMACOTHERAPY ISSUES Disinhibition, activation Medication-induced mania Cytochrome p450 inhibition Paxil, Prozac (2D6) Withdrawal symptoms That FDA warning PHARMACOTHERAPY ISSUES - CONTINUED Aug 2003 – Effexor manufacturer sends letter to MD’s saying it should not be used in depressed pediatric patients due to “signal” of suicidality in data Oct 2003 – FDA advises close monitoring of all patients on antidepressants Dec 2003 – Britain adds pediatric contraindications to Effexor, Zoloft, Celexa, and Lexapro (only Prozac is approved, others are not available) WHAT IS FDA APPROVED? Fluoxetine and Escitalopram (Lexapro) are FDA approved for use in children and adolescents with depression(7-17 yo) (and OCD) Zoloft (6-17 yo) and Luvox (8-17 yo) are FDA-approved for treatment of ObsessiveCompulsive Disorder in children and adolescents Paxil/CR and Effexor/XR are currently not recommended for use in children with depression WHAT SHOULD I, THE HEALTH CARE PROVIDER, DO? Explain the risks and advisory to parents Monitor carefully for suicidal ideations, increased agitation, or worsening of depression, especially when starting and increasing or decreasing doses This includes patients of all ages. Familiarize yourself with the use of second generation antipsychotic medications or mood stabilizers that can act as a “brake” to possible antidepressant induce mood destabilization. RECAP: IMPORTANT TAKE HOME MESSAGES Depression is treatable, but tends to be chronic with 85% who experience a single episode experiencing another episode within 15 years. For the sake of NEUROPROTECTION, do not ignore symptoms Early onset, consider Bipolar Depression Use BDI and MDQ as screening tools Be mindful Family History Discern when it is better to add mood stabilizers and/or second generation antipsychotics vs. prescribing antidepressants alone REFERRAL Psychiatric referrals may be helpful when diagnoses are in question interventions are not successful transference/counter transference issues may be interfering with treatment systems issues occur in which a “consultant” may be helpful when life threatening signs and symptoms are detected i.e. suicidality, psychosis, substance use.
