Mental health disorders

Depressive disorders are a critical topic for NEET PG, as they are common, have a significant impact on overall health, and often present in clinical practice in various forms. Here's an overview of depressive disorders, tailored to what you need to know for NEET PG: 1. Classification of Depressive Disorders Depressive disorders encompass a range of conditions, and understanding the different types is crucial for diagnosis and management. The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) and ICD-10 (International Classification of Diseases) are the primary classification systems used. Key types include: Major Depressive Disorder (MDD): Characterized by a persistent low mood, loss of interest, and other associated symptoms (e.g., sleep disturbances, appetite changes, feelings of worthlessness). Symptoms must last at least two weeks and cause significant impairment in daily functioning. It can be single episode or recurrent. Persistent Depressive Disorder (PDD) / Dysthymia: A chronic form of depression, with symptoms lasting for at least two years (one year in children and adolescents). Symptoms are less severe than in major depression but can still cause significant impairment. Bipolar Disorder: Involves both manic and depressive episodes. The depressive phase of bipolar disorder is similar to major depressive disorder. Bipolar I (more severe mania) and Bipolar II (hypomania with depressive episodes) are key distinctions. Disruptive Mood Dysregulation Disorder (DMDD): A mood disorder in children characterized by severe temper outbursts that are out of proportion to the situation. Can sometimes be misdiagnosed as ADHD. Premenstrual Dysphoric Disorder (PMDD): A severe form of premenstrual syndrome (PMS), leading to marked mood disturbances, irritability, and other depressive symptoms during the luteal phase of the menstrual cycle. Substance-Induced Mood Disorder: Depression caused by drug use, alcohol, or medications, and can be differentiated from primary depressive disorders. Psychotic Depression: Involves depressive symptoms along with psychotic features, such as delusions or hallucinations.
