Depression and mania
DSM-5 criteria describe it as an extremely depressed mood state that lasts at least 2 weeks and includes cognitive symptoms (such as feelings of worthlessness and indecisiveness) and disturbed physical functions (such as altered sleeping patterns, significant changes in appetite and weight, or a notable loss of energy) to the point that even the slightest activity or movement requires an overwhelming effort.
Major depressive episode
The most commonly diagnosed and most severe depression is called a
major depressive episode
Five (or more) of the following symptoms have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms is either (1) depressed mood or (2) loss of interest or pleasure. Note: Do not include symptoms that are clearly due to a general medical condition or mood-incongruent delusions or hallucinations.
Major depressive Disorder
Depressed mood most of the day, nearly every day, as indicated by either subjective report (e.g., feels sad, empty, hopeless) or observation made by others (e.g., appears tearful). (Note: In children and adolescents can be irritable mood.)
2. Markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day (as indicated by either subjective account or observation).
3. Significant weight loss when not dieting or weight gain (e.g., a change of more than 5% of body weight in a month), or decrease or increase in appetite nearly every day. (Note: In children, consider failure to make expected weight gains.)
4. Insomnia or hypersomnia nearly every day.
5. Psychomotor agitation or retardation nearly every day (observable by others, not merely subjective feelings of restlessness or being slowed down).
6. 7. Fatigue or loss of energy nearly every day. Feelings of worthlessness or excessive or inappropriate guilt (which may be delusional) nearly every day (not merely self-reproach or guilt about being sick).
8. Diminished ability to think or concentrate, or indecisiveness, nearly every day (either by subjective account or as observed by others).
9. Recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for suicide.
Major Depressive Episode

People with depression
reflects that these episodes represent a state of low positive affect and not just high negative affect
Anhedonia
The second fundamental state in mood disorders is abnormally
Exaggerated elation, joy, or euphoria
individuals find extreme pleasure in every activity; some patients compare their daily experience of mania with a continuous sexual orgasm.
Mania
They become extraordinarily active (hyperactive), require little sleep, and may develop grandiose plans, believing they can accomplish anything they desire.
Mania
DSM-5 highlights this feature by adding “persistently increased goal-directed activity or energy” to the “A” criteria (see DSM-5 Table 7.2) (American Psychiatric Association, 2013). Speech is typically rapid and may become incoherent, because the individual is attempting to express so many exciting ideas at once; this feature is typically referred to as
Flight of Ideas
require a duration of only 1week, less if the episode is severe enough to require hospitalization.
