Classification of mood disorders 1 - Depressive Disorders : A. major Depression Disorder (unipolar depression or clinical depression) • • • Atypical depression catatonic depression melancholic depression postpartum depression psychotic major depression seasonal affective disorders B. Dysthymia (double depression) B. Depressive disorders not otherwise specified • • recurrent brief depression minor depressive disorder

Classification of mood disorders cont. 2 - Bipolar Disorders (manic depression): a. Bipolar I b. Bipolar II c. Cyclothymic d. Bipolar disorder not otherwise specified 3 - Substance-induced mood disorders: a. Alcohol induced M. D. b. Benzodiazepine M. D.

Epidemiology l l l l 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 l l Neuroendocrine dysregulation: hypothalamus, pituitary, adrenal, thyroid, and growth hormone. l 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: l Psychoanalytic theory: depression is a result of loss - mania is a defense against depression. l Cognitive theory: depression is a result of negative processing of thoughts. l Learned helplessness: depression is a result of apperceived lack of control over events. l Life events and stress theory: significant life events cause stress, which results in depression or mania. l Personality theory: personality characteristics predispose an individual to mood disorders.

3 - Social and environmental factors: l Adverse childhood experiences lead to depressive disorders in adult life l Depression is more common in divorced men. l 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. l High rates of depression are seen in clients with chronic or painful physical illnesses

1 - Depressive Disorders l Major depressive disorder (MDD): (unipolar or clinically depression) l Is condition characterized by along-lasting depressed mood or marked loss of interest or pleasure (anhedonia) in all or nearly all activities. l 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.
