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
