Mood Disorders Practice Questions

Q: A 35-year-old male presents with episodes of intense euphoria, increased energy, and decreased need for sleep, followed by periods of severe depression. What is the most likely diagnosis?

Bipolar disorder. ***Bipolar disorder*** - The alternating episodes of **intense euphoria, increased energy, and decreased need for sleep** (manic or hypomanic symptoms) and **severe depression** are characteristic features of bipolar disorder. - This condition is defined by the presence of at least one manic or hypomanic episode, often accompanied by depressive episodes. *Major depressive disorder* - This disorder is characterized by **persistent sadness and anhedonia** but does not include episodes of elevated mood, increased energy, or decreased need for sleep. - While periods of severe depression are mentioned, the presence of euphoric and high-energy phases rules out major depressive disorder as the sole diagnosis. *Cyclothymic disorder* - Cyclothymia involves **chronic, fluctuating mood disturbances** with numerous periods of hypomanic and depressive symptoms, but these symptoms are less severe and do not meet the full criteria for manic, hypomanic, or major depressive episodes. - The description of "intense euphoria" and "severe depression" suggests a more pronounced presentation than typically seen in cyclothymic disorder. *Schizophrenia* - Schizophrenia is primarily characterized by **psychotic symptoms** such as hallucinations, delusions, disorganized thinking, and negative symptoms. - While mood disturbances can occur, they are not the primary feature, and the recurring pattern of distinct manic/hypomanic and depressive episodes is not characteristic of schizophrenia.

Q: A 30-year-old woman presents with episodes of extreme euphoria, decreased need for sleep, and hyperactivity lasting for at least one week. What is the most likely diagnosis?

Bipolar I Disorder. ***Bipolar I Disorder*** - The patient's presentation with episodes of extreme **euphoria**, **decreased need for sleep**, and **hyperactivity** lasting for at least one week are classic features of a **manic episode**. - According to DSM-5 criteria, the presence of at least one **manic episode** is sufficient for a diagnosis of Bipolar I Disorder. *Major Depressive Disorder* - This diagnosis involves persistent **depressed mood** or **loss of pleasure**, with symptoms lasting at least two weeks. - It does not involve episodes of **euphoria** or **manic symptoms**. *Bipolar II Disorder* - This disorder is characterized by at least one episode of **hypomania** and at least one **major depressive episode**. - **Hypomanic episodes** are less severe than manic episodes, do not cause significant functional impairment, and typically last for a shorter duration (at least 4 consecutive days, but less than a week). The described symptoms are of extreme euphoria and hyperactivity, pointing to mania. *Cyclothymic Disorder* - This disorder involves chronic, fluctuating moods with numerous periods of **hypomanic symptoms** and numerous periods of **depressive symptoms** for at least 2 years. - The symptoms are less severe and do not meet the full criteria for either a hypomanic or a major depressive episode.

Q: Which of the following statements about postpartum depression is false?

Symptoms resolve in 10-12 days. ***Symptoms resolve in 10-12 days*** - This statement is false because **postpartum depression (PPD)** symptoms typically last much longer, often for **several weeks to months**, and require intervention. - The resolution of symptoms within 10-12 days is characteristic of **postpartum blues**, a much milder and self-limiting condition. *Affects both sexes* - This statement is true because while more common in mothers, **paternal postpartum depression** is also a recognized condition. - Fathers can also experience significant depressive symptoms, often related to stress, lack of sleep, and changes in relationships. *SSRIs are effective* - This statement is true because **Selective Serotonin Reuptake Inhibitors (SSRIs)** are a first-line pharmacological treatment for postpartum depression. - SSRIs help regulate **neurotransmitter imbalances** associated with depression, with efficacy shown in numerous studies. *None of the above* - This option is incorrect because there is a false statement among the given choices, which is "Symptoms resolve in 10-12 days." - Therefore, this choice would only be correct if all other statements were true.

Q: Which of the following is a characteristic of mania?

High self esteem. ***High self esteem*** - **Elevated self-esteem** or **grandiosity** is a core symptom of mania, where individuals may believe they possess unique talents, abilities, or even divine connections. - This symptom contributes to an overall expansive and **euphoric mood**, characteristic of a manic episode. *Paranoid delusion* - **Paranoid delusions** are more characteristic of conditions like **schizophrenia** or **delusional disorder**, where individuals experience false beliefs of being persecuted or conspired against. - While psychotic features can occur in severe mania, **grandiosity** is more typical than paranoia. *Depressed mood* - A **depressed mood** is the hallmark of a **depressive episode**. - Mania, by definition, involves a distinct period of **abnormally and persistently elevated, expansive, or irritable mood**. *Loss of orientation* - **Loss of orientation** to time, place, or person is typically seen in conditions causing **cognitive impairment**, such as **dementia**, **delirium**, or severe organic brain disorders. - While severe mania can involve disorganized thinking, true **disorientation** is less common than in organically based cognitive disorders.

Q: A woman, who is 4 days postpartum, presented with tearfulness, mood swings, and occasional insomnia. What is the likely diagnosis?

Postpartum blues. ***Postpartum blues*** - This condition presents with mild, transient symptoms like **tearfulness**, **mood swings**, and **insomnia** typically peaking around **4-5 days postpartum** and resolving within two weeks. - It is a very common, self-limiting condition impacting up to 80% of new mothers, attributed to drastic **hormonal shifts** post-delivery. *Postpartum depression* - Symptoms are similar to postpartum blues but are more **severe**, last longer (typically **beyond two weeks**), and significantly impair functioning. - It often includes feelings of **hopelessness**, pervasive sadness, loss of pleasure, and sometimes thoughts of harming oneself or the baby. *Postpartum psychosis* - This is a severe psychiatric emergency characterized by **hallucinations**, delusions, disorganized thinking, and bizarre behavior, usually within the first 2-3 weeks postpartum. - It is a rare condition requiring **urgent medical intervention** due to the high risk of harm to mother and baby. *Postpartum anxiety* - While anxiety can co-occur with postpartum blues or depression, primary postpartum anxiety specifically involves excessive and **uncontrollable worry** or fear, often about the baby's health or safety. - It does not typically present with the prominent **tearfulness** and **mood swings** characteristic of blues or depression.

Q: A patient with depressive symptoms for 6 months now presents with auditory hallucinations that started 2 weeks ago. What is the probable diagnosis of the condition?

Major depressive disorder with psychotic features. ***Major depressive disorder with psychotic features*** - The presence of **depressive symptoms for 6 months** as the predominant and longer-standing issue, followed by the emergence of **psychotic features (auditory hallucinations)** *only during the depressive episode*, aligns with this diagnosis. - In this condition, the psychotic symptoms occur exclusively in the context of a **major depressive episode**. *Schizoaffective disorder* - This disorder requires a period of **at least 2 weeks of psychotic symptoms** (like hallucinations or delusions) *in the absence of prominent mood symptoms*. - Here, the psychotic symptoms *co-occur with and are limited to the depressive episode*, so there is no separate period where only psychosis is present. *Bipolar disorder* - This diagnosis involves episodes of **mania or hypomania**, which are not described in the patient's presentation. - While psychotic features can occur during severe depressive or manic episodes in bipolar disorder, the primary mood symptoms presented are purely depressive. *Schizophrenia* - Schizophrenia is characterized by **prominent psychotic symptoms** (hallucinations, delusions, disorganized speech/behavior) for a significant portion of time, typically lasting at least 6 months, and its diagnosis requires a **lack of prominent mood episodes** existing for *most of the active phase*. - In this case, the **mood symptoms (depression) predate and are consistently present**, indicating a primary mood disorder focus.

Q: What is the term for a profound state of depression characterized by severe symptoms and a lack of identifiable cause?

Melancholia. ***Melancholia*** - **Melancholia** is the term specifically used to describe a profound, severe state of depression that arises **without an identifiable external cause** (historically called "endogenous depression"). - It is characterized by **loss of pleasure in all activities** (pervasive anhedonia), profound despondency, distinct biological features like **early morning awakening**, **psychomotor retardation**, **worse symptoms in the morning**, and **significant weight loss**. - In DSM-5, melancholia is a specifier for major depressive episodes, but the **term itself** refers to this specific severe, endogenous form of depression lacking clear precipitating factors. - This distinguishes it from reactive depression, which has identifiable life stressors or causes. *Major depressive disorder* - **Major Depressive Disorder (MDD)** is the broader diagnostic category that encompasses various forms of depression. - MDD can be **reactive** (with identifiable precipitating causes like life stressors) or **endogenous** (without clear external triggers). - While melancholic features represent a severe subtype of MDD, the question asks for the specific **term** describing profound depression **lacking identifiable cause**, which is melancholia. *Mania* - **Mania** is characterized by abnormally elevated, expansive, or irritable mood with increased energy and activity. - It is the opposite pole of depression and is a hallmark of **bipolar I disorder**, not a form of depression. *Schizophrenia* - **Schizophrenia** is a psychotic disorder characterized by **hallucinations**, **delusions**, and disorganized thinking. - While mood disturbances can occur in schizophrenia, it is not primarily a mood disorder and does not describe a profound state of depression.
