Generalized Anxiety Disorder (GAD): Excessive worry about various aspects of life, restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbances.
Bipolar Disorder: Alternating periods of depression and mania/hypomania. Manic episodes include elevated mood, increased activity, reduced need for sleep, grandiosity, talkativeness, and risky behavior.
Risk Factors
Depression: Genetics, major life changes, trauma, chronic illness, certain medications, and substance abuse.
GAD: Family history of anxiety disorders, chronic stress, trauma, and comorbid mental health conditions such as depression.
Bipolar Disorder: Family history of bipolar disorder, high-stress levels, substance abuse, and significant life changes or traumatic experiences.

Diagnosis
Depression: Clinical evaluation using DSM-5 criteria, patient history, and self-report questionnaires like the PHQ-9.

Management/Treatment Recommendations
Depression: Antidepressants (SSRIs, SNRIs), psychotherapy (CBT, IPT), lifestyle changes, and, in severe cases, electroconvulsive therapy (ECT).
GAD: Psychotherapy (CBT), medications (SSRIs, SNRIs, benzodiazepines), lifestyle modifications, and relaxation techniques.
Bipolar Disorder: Mood stabilizers (lithium, valproate), antipsychotic medications, psychotherapy, and lifestyle changes.
Transmission and Pathophysiology
Depression: Complex interplay of genetic, biochemical, environmental, and psychological factors. Imbalance of neurotransmitters such as serotonin, norepinephrine, and dopamine.
GAD: Dysregulation of the amygdala and prefrontal cortex, neurotransmitter imbalances, and genetic predisposition.
Bipolar Disorder: Genetic vulnerability combined with environmental stressors, neurochemical imbalances, and abnormalities in brain structure and function.
Depression and Related Conditions
Primary Medical Concerns
Depression: Risk of suicide, comorbid medical conditions (e.g., cardiovascular diseases), and poor adherence to treatment.
GAD: Increased risk of cardiovascular issues, chronic pain disorders, and other comorbidities such as depression.
Bipolar Disorder: Increased risk of suicide, substance abuse, and medical comorbidities such as obesity and cardiovascular disease.
Primary Psychosocial Concerns
Depression: Social isolation, strained relationships, occupational impairment, and stigma.
GAD: Persistent worry affecting social interactions, occupational functioning, and overall quality of life.

Implications for Critical Care and Advanced Practice Nurses
Depression: Vigilance for signs of suicidal ideation, ensuring adherence to treatment, providing support, and education about the condition.
GAD: Recognizing and managing symptoms of anxiety, providing reassurance, promoting adherence to therapy, and offering coping strategies.
Bipolar Disorder: Monitoring for mood swings, managing medication adherence, providing psychoeducation, and addressing the psychosocial impacts of the disorder.
Advanced practice nurses must adopt a holistic approach to manage these conditions, considering both the medical and psychosocial aspects to provide comprehensive care and support for patients. APA.
