Bipolar Disorder for Nurses

Bipolar disorder is characterized by mood episodes that represent a change from the person's baseline. There are two primary types:

• Bipolar I: At least one manic episode (may or may not include depressive episodes). Mania in Bipolar I is severe enough to require hospitalization or cause psychotic features.
• Bipolar II: At least one hypomanic episode and one major depressive episode — no full manic episodes. Often misdiagnosed as unipolar depression.
• Cyclothymia: Chronic cycling between hypomanic and depressive symptoms that do not meet full episode criteria, lasting at least 2 years.

The lifetime risk of suicide in bipolar disorder is 15–20 times higher than in the general population, making safety assessment a constant nursing priority.

Mania

A distinct period of abnormally and persistently elevated, expansive, or irritable mood with increased goal-directed activity, lasting at least 7 days (or any duration if hospitalization is required). Must include ≥3 of the following symptoms (DIG FAST mnemonic):

• Distractibility — attention easily drawn to unimportant stimuli
• Irritability / impulsivity — low frustration tolerance, risky behaviors
• Grandiosity — inflated self-esteem, belief in special powers or connections
• Flight of ideas — racing thoughts, rapidly shifting topics
• Activity increase — goal-directed activity, psychomotor agitation
• Sleep decreased — decreased need for sleep without fatigue (key distinguishing feature)
• Talkativeness — pressured speech, difficult to interrupt

Severe mania may include psychotic features (hallucinations, delusions) and requires inpatient management. Manic patients are at risk for dangerous impulsive behaviors — sexual indiscretion, financial recklessness, substance use.

Hypomania

A less severe form of mania lasting at least 4 days. Mood is elevated or irritable; same symptoms as mania but less severe. Key distinction from mania: hypomania does not cause marked functional impairment and does not require hospitalization. No psychotic features.

• Patients often do not recognize hypomania as a problem — they may feel highly productive and resist treatment
• Hypomania can escalate to full mania, particularly with antidepressant use without a mood stabilizer
• Educate patients and families to recognize early warning signs of escalation

Depressive Episode in Bipolar Disorder

Bipolar depression presents identically to unipolar major depression in symptoms. However, treatment differs significantly:

• Antidepressant monotherapy is generally avoided — may trigger manic or mixed episodes
• Mood stabilizers (lithium, valproate, lamotrigine) are first-line
• Suicide risk is highest during depressive and mixed episodes
• Mixed states (simultaneous manic and depressive features) are particularly high-risk for suicide

• Provide a structured, predictable environment — routine reduces mood episode triggers
• Channel energy during mania into safe, solitary activities (walking, simple crafts) — avoid competitive or stimulating group activities
• Offer high-calorie, high-protein finger foods to manic patients who will not stop to eat
• Communicate in short, clear, calm statements during manic episodes — long explanations escalate agitation
• Establish consistent therapeutic boundaries — enforce limits firmly but non-confrontationally
• Monitor lithium levels, renal function, and thyroid function regularly
• Teach early warning signs of episode recurrence — sleep changes are often the first indicator
• Discuss mood charting — tracking mood daily helps patients recognize patterns

• During mania: Use a calm, firm tone. Avoid arguing or debating grandiose beliefs — do not reinforce them, but avoid direct confrontation that escalates agitation
• During depression: Use a warm, empathetic, unhurried approach. Validate the patient's experience without reinforcing hopelessness
• Consistency matters: Maintain the same approach across all staff — inconsistency is exploited by manic patients to bypass boundaries
• Psychoeducation: During stable periods, provide thorough medication and illness education — patients are most receptive when euthymic (baseline mood)

• Never stop mood stabilizers abruptly — discontinuation can trigger a severe manic episode
• Lithium: maintain consistent salt and fluid intake; report any illness, vomiting, or diarrhea to the provider immediately
• Regular sleep schedule is essential — sleep disruption is the most common trigger for manic episodes
• Avoid alcohol and recreational drugs — these destabilize mood and interact with medications
• Recognize personal early warning signs: decreased sleep need, racing thoughts, irritability, increased spending
• Have a crisis plan in place — who to call, what to do, when to go to the emergency department
• Bipolar disorder is a lifelong condition — but with treatment, meaningful, stable functioning is achievable
