Theory of Cause
Presence evaluated on a spectrum.Genetic abnormalities,
Activated (Shine)Dormant-normal development
The occurrence of stressful events.Difficult ongoing life situations with
a depletion of neurotransmitters.Grief-Support and coping skills

Genetic Basis• Depression• 20% have one episode only.• An individual with a first-degree
relative has up to 40%-50% chance with an 8% vulnerability in the general population.
• Multiple genes are involved in Depression, more prevalent in women.

Genetic Influence
Bipolar disease85% of risk inheritedMultiple genes involved in disease.
• Up to 60% chance of having the disease in identical twins.More prevalent in men.

Spectrum of Mood Disorders
DysthymicCyclothymicSchizoaffective Post-partumCo-morbid Disorders
04/22/23 10
Biochemical Basis of Mood DO
The neural networks of the brain and the prefrontal cortex.Limbic System: the emotional brain.Altered neurotransmitters: serotonin (5HT), dopamine, norepinephrine, acetylcholine (a critical neurotransmitter in brain plasticity).
04/22/23 11
Neurobiology
Depression and PTSD have shown to damage the hippocampus.Hypercortisolemia: majority of unipolar and bipolar individuals have elevated cortisol levels.This causes neurotoxic effects: hippocampal atrophy.
04/22/23 12
Organic Causes• Endocrine disorders:Diabetes, Cushing’s disease• Neurologic diseases:Parkinson’s and Alzheimer’s
disease Metabolic disturbances:Hypoxia and hypercalcemia• Cardiovascular diseases:Heart failure, Open Heart OR• Pulmonary disorders:COPD

Nursing Assessment and Interventions
Assess for suicidalityStay alert for clues to suicidal
thoughts, stay with client.Findings:A preoccupation with death.Previous suicide attempts.Presence of a plan.

Pharmacological Interventions
Antidepressants Prescribed: Variety of antidepressants that alter specific neurotransmitters.
Often 4 –6 weeks until a therapeutic result, if none another tried or added to initial
medication tried.
04/22/23 19
Non-Pharmacological Therapies
Electroconvulsive Therapy-ECTAlternative Therapy.LifestyleNutritionalHerbal: SAMe St. John’s Wort

Maintaining a Healthy Brain
A key to activating neuroplasticity:Paying Attention.
Learn something new.Evoking a mental picture will increase metabolic activity.Repeated activation strengthens areas of the brain.Exercise creates new capillaries to the brain.

Integrative Medicine
CBT (cognitive behavioral therapy) modifies sensitivity to anxiety.Family Focused Therapy: problem solving for the family and psychosocial pressuresNational Alliance for the Mentally ill
NAMIEach client needs to be an involved
member of the team.

Bipolar DisordersDepression is a low, sad state in which life seems dark and its challenges overwhelming,Bipolar is a pattern of alternating between moods.
Mania, the opposite of depression, is a state of breathless euphoria, and a frenzied energy.People have the mistaken belief that the world is theirs.

04/22/23 25
Genetic Influence
Bipolar Disease has an 85% inheritable risk.Multiple genes involved.More prevalent in men.
04/22/23 26
Neurobiology
Bipolar DO:Ventricular enlargementSmaller hippocampus (critical
for memory and emotional regulation) amygdala, temporal lobe.
04/22/23 27
Mania
Elation, euphoria, agitation or irritability, hyper-excitability, hyperactivity, rapid thought and speech, exaggerated sexuality, decreased sleep.Psychotic symptomsHypomania:An expansive, elevated, or agitated mood. Similar to mania but is less intense, no psychotic symptoms.
