Mood disorders are moods experienced outside of the normal range, longer in duration with severe symptoms and where mood and emotions are not under the individual’s control. They include major depressive disorder and bipolar disorder;
- Major depressive disorder occurs over a period of at least two weeks during which there is either depressed mood or loss of interest or pleasure in nearly all activities, accompanied by other symptoms such as insomnia and change in appetite (and weight gain or loss), energy and concentration, inappropriate feelings of guilt and worthlessness, reoccurring thoughts of death (suicidal thoughts)
- Seasonal patterns of depression, formerly known as Seasonal Affective Disorder or SAD, are indicated when there is a relationship between the onset of major depressive episodes and a particular time of year. This must occur over 2 years in which depressive symptoms are not experienced in non-seasonal periods
- Bipolar disorder is a mood disorder characterized by manic episodes of abnormally and persistently elevated, expansive or irritable mood, usually occurring separate from and in addition to episodes of major depression (there is very little written on bipolar disorder in athlete populations). During the depressive stage of bipolar disorder, several of the listed symptoms below will exist but can last for days, weeks or years before the manic stage where there is elevated mood, grandiose ideas and irritability, rapid thinking and speech, lack of inhibitions or insight and this too can last for days or months
