Bipolar disorder involves periods of depression alternating with periods of mania, which can involve unusually elevated mood reckless behavior. Historically, bipolar disorder has been known as manic depression. Periods of mania do not occur in a depressive disorder.

Individuals with Bipolar I disorder must have at least one manic episode. Bipolar II is characterized by major depression and hypomania, a state of slightly less agitation than mania, but cannot have had a manic episode. 

"Hallucinating" is the correct answer. Hallucinating is not a common attribute of a manic state. It is more commonly paired with schizophrenia. During a manic state, bi-polar patients are elated, often talking a lot, not sleeping, engaging in promiscuous activities, and being more creative. 

Sarah's symptoms are consistent with “bipolar disorder,” which includes alternating between periods of depression and mania. By definition, a manic episode must last at least one week and not be induced by drugs or alcohol. Even though Sarah experiences periods of “depression,” bipolar disorder is the more appropriate diagnosis due to her manic episodes. “Borderline personality disorder” includes symptoms related to instability in relationships, emotions, and self-image. “Generalized anxiety disorder” is characterized by excessive anxiety regarding a number of things that induces impaired functioning. Last, “schizophrenia” is a psychotic disorder that involves at least two of the following symptoms: hallucinations, delusions, disorganized thinking, disorganized behavior, and emotional flattening.

People with major depressive disorder typically give up their productivity and their motivation to complete daily tasks. Below is a comprehensive list of some of the most common symptoms of major depressive disorder.

When people are living with major depressive disorder, they experience emotional symptoms (feeling sad and dejected), motivational symptoms (loss of desire to pursue usual activities and duties), behavioral symptoms (feeling less active and less productive), cognitive symptoms (holding negative views of self, like feeling inadequate, undersireable, inferior, worthy of blame), and physical symptoms (experiencing headaches, indigestion, constipation, dizzy spells, and general pain).

Preoccupation with schedules and productivity is more indicative of an obsessive-compulsive disorder than a depressive disorder.

Learned helplessness is the perception that, based on past experiences, an individual has no control over reinforcements (rewards, punishments) in his/her life. These individuals also tend to believe that they themselves are entirely responsible for this helpless state.

Dsythymia and major depressive disorder are both mood disorders, specifically focused on depressive symptomology. The main difference between them is that dsythymia is a low grade depression that lasts multiple years, while major depressive disorder is a single, severe depressive episode.

Panic disorder is an anxiety disorder, not a depressive disorder. All other listed answer options are depressive disorders.

Dysthymia (also known as dysthymic disorder) is a mild, but long-term, form of depression. Symptoms usually last for at least two years, and cause significant interference in aspects of daily life and work. 

Major depressive disorder is the most common mood disorder and is characterized by a depressed mood and physical symptoms such as loss of appetite and fatigue for 2 or more weeks in the absence of a clear cause. SAD has the symptoms of major depressive disorder but the episodes occur seasonally, typically during winter. Dysthymia is similar to major depressive disorder but it is less severe and lasts longer (at least 2 years). Bipolar disorder involves episodes of both depression and mania. Minor depressive disorder is still being researched and you do not have to know it for the AP Psychology exam.
