Which of the following is/are included in bipolar disorders:
**Core Concept**
Bipolar disorders are a group of mood disorders characterized by extreme shifts in mood, energy, and activity levels. The underlying pathophysiology involves abnormalities in neurotransmitter systems, particularly dopamine and serotonin, which regulate mood and emotional responses.
**Why the Correct Answer is Right**
The correct answer includes all three types of bipolar disorders: Bipolar I, Bipolar II, and Cyclothymic Disorder. Bipolar I disorder is marked by at least one manic episode, while Bipolar II disorder involves at least one major depressive episode and at least one hypomanic episode. Cyclothymic Disorder is characterized by periods of hypomanic and depressive symptoms that last for at least two years.
* **Option A:** Schizoaffective Disorder - This is incorrect because Schizoaffective Disorder is a separate psychiatric disorder that involves a combination of schizophrenia symptoms and mood episodes.
* **Option B:** Attention Deficit Hyperactivity Disorder (ADHD) - This is incorrect because ADHD is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity.
* **Option C:** Dysthymic Disorder - This is incorrect because Dysthymic Disorder, now known as Persistent Depressive Disorder, is a chronic form of depression that does not involve the mood swings characteristic of bipolar disorders.
**Clinical Pearl / High-Yield Fact**
It's essential to note that the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) no longer uses the term "Bipolar NOS" (Not Otherwise Specified) and instead requires a specific diagnosis of one of the three bipolar disorders.
**Correct Answer:** C. Cyclothymic Disorder, Bipolar I Disorder, Bipolar II Disorder
