Study Notes

Emotions, Mood, and Affect

Emotions are individual responses to stimuli, reactionary and intense, lasting a short duration.
Common emotions include joy, fear, anger, disgust, and surprise, often accompanied by physiological changes such as increased heart rate or sweating.
Moods are less intense and longer-lasting, shaped by one or multiple triggers or no specific cause; they influence general expectations about the future.
Affect denotes automatic reactions to events and is the observable expression of mood, assessed through verbal and nonverbal cues.

Mental Health

Mood and affect significantly impact mental health, defined as a state of well-being allowing productive work and meaningful relationships.
Severe disruptions in mood and affect can indicate mental illness, which manifests through a combination of emotional, cognitive, and behavioral changes.
Depression and bipolar disorder notably affect daily functioning and life goals, necessitating assessment and collaborative treatment.

Normal Mood and Affect

Normal mood exists on a continuum from depression to mania, with euthymia representing a stable, functional range.
Affect evaluated based on appropriateness to context, emotional range, intensity, stability, and congruence with mood.
Common affect classifications include blunted, flat, and labile, indicating the variability and visibility of emotions.

Factors Influencing Mood and Affect

Neurologic function, personality traits, stress levels, social interactions, and overall illness status play substantial roles in shaping mood and affect.
Limbic system structures such as the amygdala, hippocampus, and medial prefrontal cortex are critical in regulating emotional responses.
High emotional instability and low conscientiousness can lead to negative mood states; conversely, emotional stability and agreeableness foster positive affect.

Health Promotion and Prevention

No definitive prevention exists for depression due to inherent biological factors, but strategies to reduce stressors include healthier dietary choices and regular exercise.
Community-specific psychosocial education can improve coping strategies and resilience against mood disorders.
Secondary prevention involves regular screenings for mood disorders and appropriate referrals for treatment.

Treatment Modalities

Nonpharmacologic therapies complement pharmacological approaches, including psychotherapy, light therapy, support groups, and meditation.
Cognitive-Behavioral Therapy (CBT) is pivotal for changing negative thought patterns and developing coping strategies.
Electroconvulsive Therapy (ECT) is effective for treatment-resistant depression, administered under careful medical supervision, and has a high success rate.

Safety Considerations

Bipolar patients are at risk of transitioning from depressive to manic episodes when prescribed only antidepressants; mood stabilizers are essential in these cases.
Transcranial Magnetic Stimulation (TMS) is FDA-approved for treating depression and anxiety, offering an alternative intervention for patients.

Normal Mood and Affect

Mood is a spectrum ranging from depression to mania, with depression characterized by sadness and irritability, while mania involves elevated mood affecting functionality.
Euthymia represents a stable mood range where fluctuations do not impair function.
