NURS 6501 Week 9 Assignment; MindMap - Depression Pathophysiology and Treatment

depression involves alterations in neurotransmitter systems, brain structure and function, neuroendocrine regulation, inflammatory processes, and neuroplasticity. 1.altered neurotransmitters include a)Serotonin- serotonin plays a crucial role in regulating mood, appetite, and sleep. Reduced serotonin levels or impaired receptor sensitivity are XXXXXXXXXXXXX commonly observed in individuals with depression. NURS-6501N-31: b)Norepinephrine- involved in the body's stress response and mood Advanced regulation. Dysregulation of norepinephrine pathways can lead to Pathophysiology-Fall symptoms such as persistent sadness and fatigue. 2025 Dr. Rutherford c)Dopamine while traditionally associated with pleasure and reward, November 28th, 2025 dopamine also modulates motivation, mood, and cognition. Dysfunctions in dopamine pathways are linked to anhedonia (loss of pleasure) and motivational deficits seen in depression. 2.Altered Brain Structure and Function a)Prefrontal Cortex involved in decision-making, emotion regulation, and executive functions, exhibits structural and functional abnormalities in individuals with depression. Reduced gray matter volume and abnormal activity patterns contribute to cognitive impairments and emotional dysregulation. pathophysiology b)Amygdala known for its role in emotional processing and the stress response, shows heightened activity and structural changes in Psychotherapy (cognitive-behavioral therapy, interpersonal therapy) depression. Overactivity of the amygdala is associated with heightened Pharmacotherapy (selective serotonin reuptake inhibitors, serotonin- negative emotions and increased susceptibility to stressors. norepinephrine reuptake inhibitors) c)Hippocampus critical for memory formation and emotional regulation, Lifestyle modifications (exercise, dietary changes, stress treatment and referrals experiences structural alterations, including reduced volume and management) Referral to psychiatry or psychology for specialized impaired neurogenesis, in depression. These changes contribute to care cognitive deficits and difficulties in emotion regulation. Collaboration with other healthcare providers for comprehensive 3.Disruptions in Neuroendocrine Systems: management Support groups and community resources a)Dysregulation of the HPA axis, the body's primary stress response depression system, is commonly observed in depression. Chronic stress leads to Hamilton Depression Rating Scale (HAM- excessive release of cortisol, a stress hormone, which can disrupt D) Beck Depression Inventory (BDI) neurotransmitter balance, impair neuroplasticity, and contribute to Structured Clinical Interview for DSM-5 depressive symptoms. (SCID) Thyroid function tests diagnostic tests b)Thyroid Dysfunction- Thyroid hormones play a crucial role in regulating Complete blood count metabolism and mood. Hypothyroidism, characterized by low thyroid (CBC) Basic metabolic panel hormone levels, is associated with depressive symptoms, including (BMP) fatigue, low mood, and cognitive impairment. Genetic predisposition Depression affects various body risk factors Traumatic life events systems, contributing to: Chronic stress 1.Increased risk of cardiovascular impact diseases Neurological conditions 2. Immune system dysfunction Substance abuse 3. Altered neuroendocrine function Medical illnesses (e.g., chronic 4. Cognitive impairment pain, cancer) signs and symptoms Medications (e.g., corticosteroids) 5. Impaired social and occupational differential diagnosis functioning 6. Substance abuse disorders 7. Suicidal ideation and attempts Persistent feelings of sadness or emptiness Loss of interest in previously enjoyed activities Changes in appetite or weight Bipolar disorder Sleep disturbances Dysthymia (persistent depressive Fatigue or loss of disorder) Adjustment disorder with energy depressed mood Difficulty concentrating or making Anxiety disorders (e.g., generalized anxiety decisions Feelings of worthlessness or guilt disorder, panic disorder) Recurrent thoughts of death or suicide Substance-induced mood disorder
