Presentation Objectives • Introduction • Classification • Epidemiology • Etiology • Comorbidity • Unipolar disorders • Bipolar disorder • Diagnostic criteria • Management • Course and prognoses • References
Introduction • Normal mood: every person experiences from time a change in his mood, which is related to everyday life events. • This is considered normal as long as it is appropriate to the event. • Mood is considered abnormal when it is excessively depressible or related out of proportion to the life experience.
Definition • Mood disorders (affective disorders): are a group of disorders characterized by disturbance in regulation of emotion, ranging from intense elation or irritability to severe depression. • These disorders often result in personal suffering, family distress, interpersonal and occupational impairment, an untold social costs.
Classification of mood disorders 1- Depressive Disorders : • major Depression Disorder (unipolar depression or clinical depression) • Atypical depression • catatonic depression • melancholic depression • postpartum depression • psychotic major depression • seasonal affective disorders • Dysthymia (double depression) • Depressive disorders not otherwise specified • recurrent brief depression • minor depressive disorder
Classification of mood disorders cont. 2- Bipolar Disorders (manic depression): • Bipolar I • Bipolar II • Cyclothymic • Bipolar disorder not otherwise specified 3- Substance-induced mood disorders: a. Alcohol induced M.D. b. Benzodiazepine M.D.
Epidemiology • 2% of the general population develop a mood disorder • Major depression fourth leading cause of disease burden in the world (WHO 2002) • 21% of women and 13% of men develop major depression. Ratio M:F ≈ 1:2 • Age of onset for major depression disorder ≈ 25 • Depression occurs more frequently in lower socioeconomic groups. • Bipolar disorders occurs more frequently in higher socioeconomic groups. • Age of onset of bipolar disorder ≈ 20 • Prevalence of bipolar disorder ≈ 1% . Ratio M:F ≈ 2:3
Etiologic Factors Related to mood disorders 1- Neuron biologic factors: • Altered neurotransmission (biochemical influences): abnormalities in various neurotransmitters as decrease in norepinephrine, low levels of serotonin in the brain, decrease in dopamine • Neuroendocrine dysregulation: hypothalamus, pituitary, adrenal, thyroid, and growth hormone. • Genetic transmission (heredity) • first degree relatives with mood disorders. (at least 3 times higher) • concordance between identical twins is high.
Etiology cont. 2- Psychological factors: • Psychoanalytic theory: depression is a result of loss - mania is a defense against depression. • Cognitive theory: depression is a result of negative processing of thoughts. • Learned helplessness: depression is a result of apperceived lack of control over events. • Life events and stress theory: significant life events cause stress, which results in depression or mania. • Personality theory: personality characteristics predispose an individual to mood disorders.
Etiology cont. 3- Social and environmental factors: • Adverse childhood experiences lead to depressive disorders in adult life • Depression is more common in divorced men. • Women, who were caring for 3 or more children under the age of 11, unemployed and without a confiding relationship, were at high risk of having depression. • High rates of depression are seen in clients with chronic or painful physical illnesses
Comorbidity With Other Disorders • Symptoms of anxiety are common in depressive disorder. • Depressive features are quite frequent in: generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, schizophrenia, schizoaffective disorder, eating disorder and personality disorder. • Substance-use disorders are common in person with mood disorder. • The incidence of depressive disorder is quite high in medical illness such as: chorea, parkinson's disease, epilepsy, stroke, migrant, myocardial Infraction, endocrinal disorders, viral infections and rheumatoid arthritis.
1- Depressive Disorders • Major depressive disorder (MDD): (unipolar or clinically depression) • Is condition characterized by along-lasting depressed mood or marked loss of interest or pleasure (anhedonia) in all or nearly all activities. • Children and adolescents with MDD may be irritable instead of sad.
Symptoms of Depression: “Space Drugs" Sleep disturbance: insomnia or hypersomnia nearly everyday. Pleasure/interest: (lack of) anhedonia in things that normally enjoy. Agitation: psychomotor agitation nearly everyday. Concentration: diminished ability to think or concentration, or indecisiveness. Energy: fatigue or loss of energy nearly everyday Depressed mound: most of day Retardation movement: psychomotor retardation nearly everyday Appetite disturbance: decreased or increased appetite and weight change. Guilt: feeling of worthlessness or excessive or inappropriate guilt. Suicidal thought: recurrent thoughts of death and suicidal ideation.
Mental Status Examination • General appearance: psychomotor retardation, decreased activity level, spontaneous movements, stooped posture and sad facial expression. • Mood/Affect: depressed mood and he sees the world through dark glasses. • Speech: slow, monotonous, answers in brief, • Perception:Hallucination, and illusions may occur in depression • Thought: negative thought about themselves, the world and the future. • preoccupation with thoughts of loss, worthlessness, guilt and death. • suicidal ideation is present in 21% of patients. • the patient may have delusions of guilt or poverty. • process: thinking is slow and difficult, the patient may take along time to answer a question.
Mental Status Examination cont. • Orientation: usually oriented to place, time and person • Memory:most of patients complain of forgetfulness and poor concentration. • Judgment/Insight: depressed patients emphasize their symptoms, they are said to have excessive insight into their condition. • Reliability:Information from depressed patients tend to emphasize the bad and minimize the good. • Impulse control: 213 of depressed patients have suicide thoughts, and about 10-15% actually complete suicide.
Diagnostic criteria • DSM IV criteria for major depression. • Five (or more) of the symptoms have been present during the same two week period and represent a change from previous functioning, depressed mood or anhedonia should be one of them.
Subtypes of Major depressive disorder • Atypical depression: is characterized by mood reactivity (ability to react to positive stimuli) and significant went gainer increased appetite, hypersomnia, a sensation of heaviness in limbs (leaden paralysis), and significant social impairment as a consequence of hypersensitivity to perceived interpersonal rejection. • Melancholic depression: is characterized by a loss of pleasure in most or all activities, a failure of reactivity to pleasurable stimuli, a worsening of symptoms in the morning hours, early morning waking, psychomotor, retardation, excessive went loss, excessive guilt.

Dysthymic Disorder (double depression) • Chronic mood disorder includes depression most of the day for most days for 2 years in adults and 1 year children and adolescents. • Diagnosis: 1- Depression for most of day for a period not less than 2 years.

In major depression the performance of person is decreasing significantly, but in dysthymia less severe and its effect on the performance is less and may continue for years. • It is believed that 50% of dysthymic pt. will have major depression later.
Depressive Disorder not otherwise specified: Any depressive disorder that does not meet the criteria for a specific disorder. It includes: • Recurrent brief depression: depressive episodes once per month at least one year, with individual episodes lasting less than 2 weeks and typically less than 2-3 days. • Minor depressive disorder: depression that does not meet full criteria for major depression but in which at least two symptoms are present for 2 weeks.

Subtypes of Bipolar disorder • Cyclothymic Disorder: chromic mood disturbance of at least 2 years' duration. Many episodes of hypomanic symptoms and depressive symptoms that do not meet criteria for a major depressive episode. • There symptoms are less severe or intense than those in major depression or manic episode.
Subtypes of Bipolar disorder cont. • Bipolar I: is distinguish by the presence or history of one or more manic episodes or mixed episodes with or without major depressive episodes. • Bipolar II: consisting of recurrent intermittent hypomanic and depressive episodes. • Bipolar disorder not otherwise specified: indicates that the patient suffers from some symptoms in the bipolar spectrum but does not fully quality for any of the three formal bipolar mentioned above.
