What is the difference between an affective disorder, psychosis and mood disorders like depression, mania etc.?

Affective disorders are a group of mental health conditions that involve disturbances in emotion. This can include mood disorders such as depression and bipolar disorder, as well as other conditions such as dysthymia and cyclothymia.

Psychosis is a term that refers to a loss of contact with reality. It can manifest in a number of different ways, including hallucinations (seeing or hearing things that are not really there) and delusions (believing things that are not true).

Depression is a mood disorder characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in activities. It can also cause physical symptoms such as fatigue, changes in appetite, and difficulty sleeping.

Mania is a state of elevated or irritable mood, energy, and activity levels. It is a symptom of bipolar disorder, but can also occur as a result of other medical conditions or the use of certain substances.

It's important to note that these are just general definitions, and there can be overlap between these different conditions. It's always best to consult with a mental health professional for a proper diagnosis and treatment plan
