Questions and Answers

What role does pharmacotherapy play in the management of mood disorders?

  • It may be needed initially for patients who cannot engage with therapy. (correct)

    Study Notes

    Mood Disorder Diagnosis and Management

    • Diagnosis and management of mood disorders involves a multi-faceted approach that considers both pharmacotherapy and non-pharmacologic therapies.
    • Pharmacotherapy for mood disorders focuses on identifying and treating the specific poles of the disorder (e.g., manic or depressive).
    • Non-pharmacologic therapies include psychotherapy and are often introduced once patients show some improvement with medication.
    • Combination therapy is recommended for most patients with true mood disorders, with both pharmacotherapy and non-pharmacologic therapies.
    • Mood stabilizers are used for bipolar I and bipolar II disorders and can include medications like valproic acid, carbamazepine, and lithium, as well as lamotrigine.
    • Antipsychotics are also prescribed for bipolar disorder, specifically for managing manic episodes and depressive phases.
    • Antidepressants are not typically used as monotherapy in bipolar disorder, but they can be used in conjunction with mood stabilizers or antipsychotics.
    • SSRI's, SNRIs, and other antidepressants are used to treat major depressive disorder to increase serotonin concentration and improve mood.
    • Effective diagnosis is essential for appropriate mood disorder management.
    • A mood disorder diagnosis requires that someone meets specific criteria and that symptoms produce impairment in social and occupational functions.
    • "Mood disorders" is a broad term and refers to a spectrum of abnormalities that occur within the realm of mood.
    • Five levels of mood are used to evaluate moods, which are not specific to the speaker of this text.

    Mood Disorders: Physiological Basis

    • Resting potential voltage of neurons is roughly between -60 and -70 millivolts.
    • Depolarizing stimulus raises the voltage, triggering an action potential when threshold is reached.
    • Neurotransmitters crucial to mood regulation include serotonin, norepinephrine, dopamine, and glutamate.
    • Imbalances in these neurotransmitters lead to mood disorders.
    • Dopamine, a feel-good neurotransmitter, is involved in euphoria and psychoses.
    • Cocaine blocks dopamine reuptake, leading to increased dopamine concentration and exaggerated euphoria or psychoses.
    • Three main mechanisms for neurotransmitter inactivation are diffusion, enzymatic degradation, and reuptake.

    Brain Regions Involved in Mood Regulation

    • Anterior Cingulate Cortex (ACC) plays a role in mood regulation and attention allocation.
    • ACC also contributes to emotional expression and response to stimuli.
    • Dorsomedial Prefrontal Cortex (DMPFC) coordinates cognitive and emotional function.
    • Dorsolateral Prefrontal Cortex (DLPFC) controls higher-order cognitive function like abstract thinking, multitasking, and inhibiting inappropriate emotional responses.
    • Ventrolateral Prefrontal Cortex (VLPFC) is linked to emotional aspects like reward and motivation.

    Mood Disorder Diagnosis and Management

    • Understanding mood disorder types is crucial for effective treatment.
    • Major depressive disorder (MDD) involves cycles between euthymia and depressive episodes.
    • Patients with MDD usually experience at least five out of nine symptoms.
    • MDD is often effectively treated with antidepressants.
    • Bipolar II disorder is characterized by alternating periods of euthymia and depression, with at least one hypomanic episode.
    • Cyclothymic disorder is marked by fluctuating moods, not meeting the criteria for depression or mania.
    • Patients with cyclothymic disorder often receive a diagnosis of "mood disorder not otherwise specified."
    • Careful assessment is necessary for accurate diagnosis because misdiagnosis can lead to ineffective treatment.
    • Recurrent mood changes that significantly affect social or occupational function are characteristic of mood disorders.

    Neurotransmitter theory

    • A recent study suggests that the neurotransmitter theory of depression might be incorrect
    • The study is not conclusive and more research is needed
    • Correcting neurotransmitter balance in some patients can improve their mood
    • It's possible that the improvement in mood is caused by an unknown mechanism
    • Depression is still considered to be related to chemical transmitters and synapses

    Areas of the brain

    • Presynaptic and postsynaptic neurons are important for understanding depression
    • The locus coeruleus and the raphe nucleus are areas of interest in the brainstem
    • Low levels of neurotransmitter activity in these areas are often found in people with depression
    • When neurotransmitter activity is increased in these areas, mood often improves
    • The mechanism for how neurotransmitter activity impacts mood is not fully understood

    Bipolar Disorder

    • Bipolar disorder is characterized by two poles: depressive and manic/hypomanic states
    • The physiology of mania is not well understood
    • Medications can help control mania and stabilize mood

    Brain Regions Important for Mood

    • The cingulate cortex plays a role in mood regulation, attention allocation, and emotional expression
    • The dorsomedial prefrontal cortex coordinates cognitive and emotional function
    • The dorsolateral prefrontal cortex is involved in higher-order cognition, including abstract thinking, executive function, and inhibiting inappropriate emotional responses
    • The ventrolateral prefrontal cortex is linked to emotional aspects like reward and motivation

    Diagnosis & Treatment

    • It is crucial to evaluate for a history of cycling when a patient presents with depressive symptoms
    • Always assess for a history of elevated mood (mania or hypomania) before diagnosing depression
    • Antidepressants should not be used to treat bipolar disorder as they can worsen manic episodes
    • Depression is often managed with antidepressants, SSRIs, and SNRIs
    • Nondrug therapy is also important for managing depression
    • Bipolar disorder is typically managed with mood stabilizers or antipsychotics
    • The choice of medication for bipolar disorder depends on the patient's current mood and treatment goals
    • Mood stabilizers can target either manic or depressive poles of bipolar disorder
    • Many antipsychotics are now used for bipolar depression
