  2. Mood Disorders Emotional extremes of mood disorders come in two principal forms. • Major depressive disorder • Bipolar disorder

  3. Major Depressive Disorder Depression is the “common cold” of psychological disorders. In a year, 5.8% of men and 9.5% of women report depression worldwide (WHO, 2002). Blue mood Major Depressive Disorder Gasping for air after a hard run Chronic shortness of breath

  4. Major Depressive Disorder Major depressive disorder occurs when signs of depression last two weeks or more and are not caused by drugs or medical conditions. Signs include: • Lethargy and fatigue • Feelings of worthlessness • Loss of interest in family & friends • Loss of interest in activities

  5. Explaining Mood Disorders Since depression is so prevalent worldwide, investigators want to develop a theory of depression that will suggest ways to treat it. Lewinsohn et al., (1985, 1998) note that a theory of depression should explain the following: • Behavioral and cognitive changes • Common causes of depression

  6. Theory of Depression • Gender differences

  8. Suicide Statistics • National differences • Racial differences • Gender differences • Age differences • Other differences Suicide The most severe form of behavioral response to depression is suicide. Each year some 1 million people commit suicide worldwide.

  9. Biological Perspective Genetic Influences: Mood disorders run in families. The rate of depression is higher in identical (50%) than fraternal twins (20%). Linkage analysis and association studies link possible genes and dispositions for depression. Jerry Irwin Photography

  11. Social-Cognitive Perspective The social-cognitive perspective suggests that depression arises partly from self-defeating beliefs and negative explanatory styles.

  12. Negative Thoughts and Moods Explanatory style plays a major role in becoming depressed.

  13. Depression Cycle • Negative stressful events. • Pessimistic explanatory style. • Hopeless depressed state. • These hamper the way the individual thinks and acts, fueling personal rejection.

  14. Bipolar Disorder Formerly called manic-depressive disorder. An alternation between depression and mania signals bipolar disorder. Depressive Symptoms Manic Symptoms Gloomy Elation Withdrawn Euphoria Inability to make decisions Desire for action Tired Hyperactive Slowness of thought Multiple ideas
