Bipolar Disorders and Clinical Management

Demographic Distribution and Lifetime Risk

• Total Lifetime Risk: The lifetime risk for developing bipolar-related disorders is approximately $4.4\%$.
• Gender Comparison: Rates of incidence between men and women are nearly equal.

Pediatric and Adolescent Considerations

• Diagnosis of DMDD: Children and adolescents are more likely to be diagnosed with DMDD (Disruptive Mood Dysregulation Disorder) rather than bipolar disorder.
• Rationale for DMDD Over Bipolar:
  • Developmental Factors: Factors such as puberty and general development make it difficult to determine if symptoms are part of a permanent disorder or a developmental phase.
  • Stigma and Documentation: A bipolar diagnosis at an early age can follow a student through the school district, potentially hindering their access to proper education.
  • Clinical Accuracy: Providers tend to avoid a bipolar diagnosis in young patients unless they are "absolutely positive."

Postpartum Considerations

• Risk Elevation: Individuals with bipolar disorder have a risk factor for postpartum depression that is up to $4\times$ higher than the general population.
• Clinical Vigilance: Patients already hospitalized for bipolar episodes who become pregnant or have a baby require close monitoring for postpartum depressive symptoms.

Classification of Bipolar and Related Disorders

• Bipolar I Disorder: Considered the most severe form, characterized by a high mortality rate. To meet the criteria, the patient must have experienced at least one manic episode.
• Bipolar II Disorder: Characterized by at least one hypomanic episode and at least one major depressive episode.
  • Depressive phases in Bipolar II are often marked by dark thoughts and a high incidence of self-harm.
• Cyclothymic Disorder (Cyclothymia): Involves symptoms that alternate from mild to moderate for at least $2\text{ years}$.
  • Seasonal Patterns: The speaker notes a "spring uphill" phenomenon where mania may emerge around March, April, or May and then die off into a depressive mode.
  • Early Presentation: Often emerges in adolescent years or early adulthood, characterized by behaviors such as running away from home or skipping school.
• Rapid Cycling: Defined as having multiple cycles (at least four) within a year, particularly when the condition is unmanaged.
• Substance/Medication-Induced Bipolar: Triggered by high concentrations of substances, specifically mentioning THC (marijuana or gummies). Once the "light switch" is flipped by high-potency substances, the disorder often persists.
• Bipolar Due to Medical Conditions: Imbalances in neuroendocrine systems (e.g., thyroid) or inflammation can disrupt brain chemistry. Conditions affecting the renal/kidney, cardiovascular, respiratory, and even cancer can trigger bipolar symptoms.

Manic vs. Hypomanic Manifestations

• Mania:
  • Charactersitics: Hyperactive, impulsive, racing thoughts, and high-risk activities.
  • Attitude toward Treatment: Some patients view mania as a "superpower" (citing examples like Britney Spears, musicians, or magicians) and may refuse medication because they believe it dampens their creativity or success.
  • Escalation: Patients may remain in a manic state until psychosis sets in.
• Hypomania:
  • Detection: Harder to detect than full mania.
  • Speech/Activity: Patients remain talkative and active but in a less "loud" or blatant manner than full mania; it is often described as a state of euphoria.
  • Productivity Paradox: Patients may appear highly organized or busy with three or four projects at once, though they may never finish them.
  • Physical Indicators: Increased energy, sleep deprivation, and poor eating habits are still present but behavior is generally "less risky" than in mania.
  • Differential Diagnosis: Often confused with ADD/ADHD due to the high activity level.

Comorbidities and Complications

• Anxiety Disorders: Bipolar I is frequently associated with almost all anxiety disorders, including panic attacks, social anxiety, and phobias.
• Other Conditions: ADHD, impulsive control disorders, and conduct disorders often complicate the diagnosis in children.
• Eating Disorders: Binge eating and other eating disorders are highly associated with Bipolar II, particularly during the depressive or hypomanic sides.
• Sleep Disorders: A telltale sign of cyclothymic disorder, often cited as the precipitating factor for the onset of symptoms.

Risk Factors and Etiology

• Genetic Factors: Strong hereditary component.
• Neurobiological: Involvement of the neuroendocrine system (thyroid), inflammation, and chemical imbalances.
• Environmental Factors: Adverse Childhood Experiences (ACEs) and PTSD.
• Cognitive Factors: Pre-existing mental decline, academic struggles, or conditions like Alzheimer's, dementia, or autism.

Clinical Judgment and Verbal Communication Management

• Assessment Tools: The Altman celebrating mania scale is used to assess mood.
• Managing Manipulative Behavior (Splitting):
  • Bipolar patients can be highly manipulative, asking different staff members for the same request until they get the answer they want.
  • Strategy: Staff must remain consistent and firm with boundaries. When splitting occurs, assign one specific person to give the patient all their answers to ensure a unified front.
• Professionalism: Nurses should never discuss last names and may need to turn their badges around if they have unique names to prevent patients from tracking them outside the facility.
• Staff Safety: Psychiatric patients can be "psychotically strong." Staff must never sabotage one another (e.g., sending a disliked colleague into a room with an aggressive patient) as this leads to serious injury.

Assessment of Thought Processes and Speech Patterns

• Pressured Speech: Rapid, forceful speech.
• Circumstancial: Talking at length with excessive detail before eventually reaching the point.
• Tangential: Going "down the rabbit hole" and never returning to the original topic, leaving both the speaker and listener confused.
• Loose Associations: Fragmented thoughts that are only vaguely connected (e.g., claiming a simple shoulder tap for wake-up was a "ninja attack").
• Flight of Ideas: Rapidly shifting from one topic to another (e.g., moving from a shirt color to exam three without transition).
• Clang Associations: Grouping words based on sound/rhyme rather than meaning (Example: "Hot trot").
• Grandiose Delusions: Inflated ego or ideas of power, wealth, or status (e.g., claiming to own the hospital, being a multimillionaire, or promising patients million-dollar bonuses).
• Persecutory Delusions: Continuous accusations, often regarding jealousy, cheating, or betrayal (e.g., accusing a nurse of messing with their husband or stealing food stamps).

Case Study: The Severe Manic Patient

• Presentation: A patient hospitalized for $3\text{ years}$ who consistently appeared "butt naked" for every meal.
• Background: Discovered to have been sexually molested by her father starting at age $3$. Her condition progressed from depression to psychosis to catatonia.
• Hygiene Management (Forced Care): Because it is considered legal neglect to leave a patient unwashed, staff had to perform forced baths, forced shaving, and forced teeth brushing.
• Behavioral Complications: The patient would masturbate loudly and had pica-like behaviors involving fecal matter (eating feces found in her braces) and foreign objects (a banana used for masturbation that required medical removal).
• Clinical Note: This illustrates the "holistic care" required for patients who cannot perform daily functioning for themselves.

Nursing Diagnoses and Care Priorities

• Common Nursing Diagnoses: Risk for injury/violence, sleep deprivation, altered cognitive concentration, and self-care deficit.
• Acute Phase Priorities:
  • Prevention of injury.
  • Monitoring cardiac status due to physical exhaustion and high heart rates.
  • Hydration and tissue integrity (providing fluids for dry mouth caused by medications).
  • Ensuring sufficient sleep.

Pharmacological Considerations

• The Antidepressant Switch: Using antidepressants (e.g., Wellbutrin) on a bipolar patient who is in a depressive phase can "flip the switch" and trigger an acute manic episode.
• Long-term Management: Bipolar patients typically require medication for their entire lifetime. Families must be educated to recognize when tolerance is built and adjustments are needed.
• Severe Interventions: Seclusion, physical restraints, and ECT (Electroconvulsive Therapy) may be necessary during the acute phase to manage tissue-failing levels of agitation or treatment resistance.

Questions & Discussion

• Question (Student): For Bipolar II, is hypomanic more of a low period?
• Response: It is a "low" type of mania, but still mania. We will talk more about specific meanings, but understand they have manic and hypomanic periods as well as severe depressive lows.
• Question (Student): Is it possible for a Bipolar II diagnosis to be re-diagnosed as Bipolar I?
• Response: Yes. However, once you are diagnosed as Bipolar I, you do not "go down" to Bipolar II. It is not a level-based system. Sometimes Bipolar I is misdiagnosed as II initially because the family or patient misrepresents the severity of symptoms to the physician.
• Question (Student): Why would a patient abuse Imodium?
• Response: Patients sometimes report getting high off of Imodium (loperamide) or use it to self-medicate when they stop fixing their own symptoms. Other over-the-counter items like Sudafed, Benadryl, or even huffing cans are used to achieve a high.
• Discussion on Insurance: The speaker notes that sometimes a diagnosis is chosen based on what insurance covers. For example, some medications work better for Bipolar I but may only be covered under a specific diagnostic code. Similar situations occur in nursing homes where Alzheimer's patients are put on antidepressants to get approval for other antipsychotic medications.
