Definition:

"Mood and anxiety disorders consist of a large group of distressing mental disorders. Depressive disorders are characterized by depressed mood and diminished interest in almost all activities. Symptoms of bipolar disorders include elevated mood and increased energy that may or may not occur along with symptoms of depression. The main characteristics of anxiety disorders are excessive fear, anxiety, or worry and often avoidance of situations that provoke these strong emotions. Mood and anxiety disorders interfere with relationships with family and peers, cognitive abilities, and performance at school (Birmaher, Arbelaez, & Brent, 2002; Youngstrom, Birmaher, & Findling, 2008). [...] these disorders were grouped together because they often occur together and medications used to treat them are similar." in Chartier et al., 2016.

"Mood and anxiety disorders represent a broad spectrum of conditions that range from poor adjustment reactions and anxiety state to anxiety disorders, phobic disorders, obsessive-compulsive disorders, depressive disorders, affective psychoses, and neurotic depression (Doupe et al., 2008; Martens et al., 2004; Martens et al., 2010)." in Brownell et al., 2012.

Mood disorder is the term given for a group of diagnoses in the Diagnostic and Statistical Manual of Mental Disorders (DSM) classification system where a disturbance in the person's mood is hypothesized to be the main underlying feature. Anxiety disorder is a group of diagnoses in this classification system that includes one or more anxiety disorders as the main diagnosis (Brownell et al., 2012).
