F39: Unspecified mood [affective] disorder

Unspecified mood disorders, also known as affective disorders, represent a group of conditions that primarily impact an individual's emotional state or mood. These disorders might be characterized by feelings of extreme sadness, elation, or a combination of both. While the exact cause of these disorders is not pinpointed, a combination of genetic, biological, environmental, and psychological factors are thought to contribute. Symptoms can vary significantly but often include persistent feelings of sadness or an excessively happy mood, drastic changes in appetite and sleep patterns, loss of interest in activities previously enjoyed, or difficulty in concentrating. These mood variations are above and beyond the normal ups and downs of daily life and can impact daily functioning. The course of these disorders can also vary wildly, from single episodes occurring only once in a lifetime to multiple episodes over a period. These disorders can affect both the mental and physical wellbeing of an individual.
