Mood Disorders Practice Questions

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.

Q: Which of the following is a common feature associated with mania?

Flights of ideas. ***Flights of ideas*** - A **flight of ideas** is characterized by a rapid, continuous, pressured flow of talk with abrupt changes from one topic to another, usually based on understandable associations or plays on words, which is a hallmark feature of **mania**. - This symptom reflects the accelerated thinking and heightened energy typical of a **manic episode**. *Neologism* - **Neologisms** are newly coined words or phrases, often without meaning to others, which are more commonly associated with thought disorders like **schizophrenia**. - While patients with mania can have pressured speech, the formation of nonsensical new words is not a primary or common feature of the condition. *Perseveration* - **Perseveration** involves the persistent repetition of a word, phrase, or gesture despite the absence of a stimulus or the appropriateness of the repetition, often seen in **cognitive disorders** or **schizophrenia**. - It differs from the rapidly shifting topics in a flight of ideas, where new thoughts are constantly being generated rather than a single thought being repeated. *Echolalia* - **Echolalia** is the automatic repetition of vocalizations made by another person, which is mainly observed in conditions such as **autism spectrum disorder** or **Tourette's syndrome**. - This symptom involves imitation rather than the spontaneous generation of accelerated speech and thoughts characteristic of mania.

Q: What is the core feature required for diagnosing a manic episode?

Elevated mood. ***Elevated mood*** - The **DSM-5 criteria** for a manic episode explicitly state that an abnormally and persistently **elevated, expansive, or irritable mood** must be present for at least one week. - This core mood disturbance is what differentiates mania from other psychiatric conditions and is a prerequisite for diagnosis. *Grandiosity* - While **grandiosity** (inflated self-esteem or sense of importance) is a common associated symptom of a manic episode, it is not the sole diagnostic requirement. - It is one of several symptom criteria that must be present in addition to the mood disturbance for a diagnosis of mania. *Decreased appetite* - **Decreased appetite** is generally not a feature of a manic episode; in fact, individuals in a manic state often have an **increased appetite** or engage in impulsive eating due to lack of inhibition. - A decreased appetite is more commonly associated with depressive episodes. *Increased sleep* - **Increased sleep** is contrary to the typical presentation of a manic episode, where individuals often experience a **decreased need for sleep** and can function on very little sleep, feeling energized. - A significant reduction in the need for sleep is a characteristic symptom of mania, not an increase.

Q: Cyclothymia is classified as which type of mood disorder?

Bipolar mood disorder. ***Bipolar mood disorder*** - **Cyclothymia (Cyclothymic Disorder)** is classified under **Bipolar and Related Disorders** in both DSM-5 and ICD-11, making it part of the bipolar spectrum. - It is characterized by **chronic, fluctuating mood disturbances** lasting at least 2 years (1 year in children/adolescents) with numerous periods of hypomanic and depressive symptoms that do not meet full criteria for hypomanic or major depressive episodes. - The alternating, less severe mood swings share the fundamental **bipolar pattern** of mood elevation and depression, hence its classification under bipolar mood disorders. *Major depression* - **Major depressive disorder** is a unipolar mood disorder involving persistent feelings of sadness, loss of interest, and other depressive symptoms that significantly impair daily functioning, **without any episodes of mania or hypomania**. - Cyclothymia involves **mood instability with both elevated and depressed periods**, which distinguishes it from unipolar major depression. *Dysthymia* - **Dysthymia** (now termed **Persistent Depressive Disorder** in DSM-5) is characterized by chronic, low-grade depressive symptoms lasting at least 2 years, **without manic or hypomanic episodes**. - While both involve sub-threshold symptoms, cyclothymia includes periods of **hypomanic symptoms** (elevated mood, increased energy), which are absent in dysthymia. *Persistent mood disorder* - This is a broad, non-specific descriptive term rather than a formal diagnostic category in DSM-5 or ICD-11. - While cyclothymia is indeed a persistent condition, it is **specifically categorized under Bipolar and Related Disorders** due to the presence of both elevated (hypomanic) and depressed mood states.

Q: All are required to diagnose major depression except?

Nihilistic ideas. ***Nihilistic ideas*** - While nihilistic ideas (e.g., belief that life is meaningless or that nothing matters) can occur in severe depression, they are **not a mandatory diagnostic criterion** for major depressive disorder (MDD). - The diagnosis of MDD requires a specific number of core symptoms, and nihilistic ideation is not listed as one of them in diagnostic manuals like the DSM-5. *Depressed mood* - A **depressed mood** for most of the day, nearly every day, is one of the two **cardinal symptoms** required for a diagnosis of major depressive disorder. - The other cardinal symptom is anhedonia (loss of interest or pleasure). *Insomnia* - **Insomnia** (difficulty falling or staying asleep) or hypersomnia (sleeping excessively) is a common neurovegetative symptom of major depressive disorder and is one of the **nine diagnostic criteria**. - At least 5 of these 9 criteria must be present for a diagnosis, including at least one of the two cardinal symptoms. *Decreased concentration* - **Diminished ability to think or concentrate**, or indecisiveness, is another of the **nine diagnostic criteria** for major depressive disorder. - This cognitive symptom highlights the impact of depression on mental function beyond mood.

Q: Which neurotransmitter is believed to be increased in mania?

Increased dopamine. ***Increased dopamine*** - **Dopamine** is the primary neurotransmitter implicated in the pathophysiology of mania according to the **dopaminergic hypothesis** of mood disorders. - Increased dopaminergic activity in the **mesolimbic and mesocortical pathways** contributes to the core symptoms of mania including **euphoria**, **increased goal-directed activity**, **reduced need for sleep**, **psychosis**, and **impulsivity**. - Evidence includes: response to dopamine antagonists (antipsychotics) in treating mania, and dopamine agonists can precipitate manic episodes. - Studies using neuroimaging and CSF analysis support elevated dopamine activity during manic episodes. *Increased norepinephrine* - While norepinephrine is also increased in mania and contributes to **arousal**, **attention**, and **energy levels**, it is considered a secondary or contributory mechanism rather than the primary pathophysiological change. - The **catecholamine hypothesis** suggests both dopamine and norepinephrine are elevated, but dopamine plays the more central role in the characteristic manic symptoms. *Decreased dopamine* - Decreased dopamine is associated with **depression**, **Parkinson's disease**, and **negative symptoms of schizophrenia**, not mania. - Low dopamine leads to reduced motivation, anhedonia, psychomotor retardation, and lack of energy—the opposite of manic presentation. *Decreased norepinephrine* - Decreased norepinephrine is linked to **depressive states**, characterized by low energy, poor concentration, and reduced arousal. - This is directly contrary to the hyperarousal, excessive energy, and heightened activity seen in mania.

Q: Which mental health condition is most commonly associated with suicide?

Depression. ***Depression*** - **Depression**, particularly severe forms, is consistently identified as the leading mental health condition associated with an increased risk of **suicide**. - Symptoms like **hopelessness**, **anhedonia**, and psychomotor retardation can contribute to suicidal ideation and acts. *Alcohol dependence* - While **alcohol dependence** significantly increases suicide risk, it is often comorbid with depression or other mental disorders, making depression a more direct primary association. - Alcohol can lower inhibitions and impair judgment, increasing the impulsivity of suicidal acts. *Dementia* - **Dementia** is not commonly associated with suicide, primarily because cognitive decline often diminishes the capacity for complex suicidal planning. - The risk of suicide in dementia is generally lower compared to other mental health conditions, though early stages might involve depression. *Schizophrenia* - Individuals with **schizophrenia** have a significantly elevated suicide risk, particularly in the early stages of illness and during acute exacerbations. - However, the overall prevalence of depression as a primary contributing factor to suicide is higher across the general population.

Q: Clang associations are primarily associated with which of the following conditions?

Mania. ***Mania*** - **Clang associations** are a characteristic **thought disorder** seen in mania, where a person selects words based on their **sound (rhyming)** rather than their meaning or logical connection. - This symptom reflects the **pressured speech** and **racing thoughts** commonly observed during manic episodes. - **Classic example**: "I'm feeling fine, wine, dine, spine" - words rhyme but lack logical connection. *Depressive disorder* - Patients with depressive disorder typically experience **paucity of speech** or **slowed thoughts**, not clang associations. - Their thought content often focuses on themes of **hopelessness, guilt, or worthlessness**. *Psychotic disorder* - While psychotic disorders like **schizophrenia** can occasionally involve clang associations during acute episodes, they are **much more classically and prominently** associated with **mania**. - Schizophrenia more typically shows other thought disorders like **loose associations, derailment, or word salad**. - Other psychotic symptoms like **delusions** and **hallucinations** are more central to psychotic disorders. *Anxiety disorder* - Anxiety disorders are characterized by excessive **worry, fear**, and **physical symptoms of arousal**. - They do not involve formal **thought disorders** like clang associations; thought content is usually coherent but focused on anxious themes.

Q: Which of the following is not a required symptom for the diagnosis of major depression?

Nihilistic ideas. ***Nihilistic ideas*** - While nihilistic ideas (feelings that life is meaningless or that nothing exists) can occur in severe depression, they are **not a core diagnostic symptom** required by the DSM-5 criteria for major depressive disorder. - The diagnosis of major depression requires at least five specific symptoms, including either depressed mood or anhedonia, but **nihilism is not one of these mandatory criteria**. *Depressed mood* - This is one of the **two core symptoms** required for a diagnosis of major depressive disorder, alongside anhedonia. - The individual must experience a **subjective feeling of sadness, emptiness, or hopelessness**, or appear tearful to others, for most of the day, nearly every day. *Anhedonia* - This is the **other core symptom** required for a diagnosis of major depressive disorder if depressed mood is not present. - It refers to a **markedly diminished interest or pleasure** in all, or almost all, activities most of the day, nearly every day. *Significant weight loss* - **Significant unintentional weight loss** or weight gain (e.g., a change of more than 5% of body weight in a month) or **decrease/increase in appetite nearly every day** is one of the associated symptoms that can contribute to a diagnosis of major depression. - Changes in appetite or weight are common somatic symptoms associated with **mood dysregulation** in depression.

Q: Disturbances in sleep due to depression are associated with which of the following?

Decreased REM (rapid eye movement) latency. ***Decreased REM (rapid eye movement) latency*** - **Decreased REM latency** (shortened time from sleep onset to first REM period, typically <60 minutes vs normal ~90 minutes) is the **most specific and well-established polysomnographic finding** in major depressive disorder. - This neurobiological marker reflects dysregulation of sleep architecture and is used as a **biological marker** in depression research. - Other REM changes include **increased REM density** (more rapid eye movements per REM period) and **prolonged first REM period**. *Changes in REM sleep architecture* - While this statement is technically correct (decreased REM latency is a change in REM architecture), it is **too broad and non-specific**. - This option lacks the precision needed for a clinical diagnosis, as many psychiatric and medical conditions alter REM architecture. - The question asks for the specific disturbance most associated with depression, making **decreased REM latency** the superior answer. *Occasional vivid dreams* - Vivid dreams are **not a characteristic or diagnostic feature** of depression-related sleep disturbance. - More commonly associated with **REM rebound** (after REM suppression), **narcolepsy**, **PTSD**, or certain medications (e.g., beta-blockers, antidepressants). *Insomnia and fragmented sleep* - While **early morning awakening** (terminal insomnia), difficulty maintaining sleep, and fragmented sleep are common clinical symptoms of depression, they are **non-specific**. - These symptoms occur in many conditions and describe subjective sleep quality rather than the **objective neurophysiological marker** that decreased REM latency represents.
