Bipolar
|
moods swinging from depression to mania. It is often referred to as manic
|
|
Mania
|
Mania is a feeling of euphoria, irritability, and unpredictability accompanied by increased energy and increased involvement in activities.
|
|
etiology of Bipolar
|
Bipolar disorder is considered by most researchers to be a chemical imbalance. The neurotransmitter changes are thought to be a change in serotonin, norepinephrine, and dopamine levels. When these neurotransmitters are decreased the person experiences a depressed mood. When these neurotransmitters are increased the person experiences a hypomanic or manic mood.

etiology of Bipolar
|
1.neurochemical
2.genetic link in the majority of people diagnosed with bipolar disorder. Children who have a parent with bipolar disorder are 4-6 times more likely to inherit the illness. 3.ages of 15-35;east 50% are diagnosed before the age of 25 years 4.environment 5.Two common defense mechanisms seen with bipolar disorder includes denial. It is difficult for a manic or hypomanic individual to see or hear the symptoms as being abnormal. The person perceives that the manic or hypomanic symptoms are normal. 6.substance abuse 7.ADHD-A person who is diagnosed with attention deficit hyperactivity disorder or ADHD runs a high risk for being diagnosed with bipolar disorder. The symptoms of hyperactivity, restlessness, talkative, interrupting, and difficulty with concentration is seen in both illnesses 8.Side effects of meds |
|
S/S of Mania
Onset before "30" Mood- elevated expansive irritable Speech- loud & rapid punning rhyming clanging vulgar ?Wt. loss Grandiose Delusions Distracted Hyperactive Decrease for Sleep Inappropriate Flight of Ideas Begins suddenly escalates over several days |
S/S of Depression
Previous manic episodes Mood- dysphoric depressive despairing Decrease interest in pleasure Negative views Fatigue Decrease appetite Constipation Insomnia Decreased Libido Suicidal preoccupation May be agitated or have movement retardation |
|
Acronym for Mainia
DIGFAST Distractibility -poorly focused, multitasking Insomnia-decreased need for sleep Gradiosity- inflated self-esteem Flight of Ideas- complaints of racing thoughts Activities- increased goal-directed activities Speech- pressured or talkative Thoughtlessness- risk taking behaviors(sexual, financial, travel, driving) |

Intervention: Assess learning barriers Assess knowledge of illness and treatment Implement teaching on illness, meds and other treatment modalities Review discharge safety plan and relapse prevention |
|
Antimanic Medications
|
Purpose: treat bipolar disorder (manic or depressed), seizure disorders, and/or CNS pain.
Route: po (for bipolar disorder-capsules, tablets, or concentrates) Frequency: daily for treatment of bipolar disorder |
|
Antimanic Medications
|
Effectiveness: 7-14 days before medication becomes effective.
Medications: Lithium carbonate (Eskalith, Eskalith CR, Lithane, Lithotabs, Lithobid, Lithicarb). Lithium citrate (Cibalith-S). Action: May influence reuptake of neurotransmitters possibly by interfering with ionic pump mechanisms in brain cells and may compete with or replace sodium ions. |
|
Antimanic Medications
Side effects |
Side effects: These side effects usually decrease after the 6th week of treatment
-HA -Fine hand tremors, -Polyuria -Mild thirst -Mild nausea -Weight gain -Edema -Dry mouth -Metallic taste -Hyperglycemia (nephrogenic diabetes insipidus) -Hypothyroidism. |
|
Antimanic Medications
Lithium |
Lithium levels: Therapeutic levels are 0.5-1.5 mEq/L. Maintenance levels are
0.6-1.2 mEq/L. Drawn 8-12 hours after last dose given. Drawn weekly until therapeutic level is reached. Than, drawn monthly. Lithium has a narrow therapeutic margin of safety. |
|
Antimanic Medications
Lithium Toxicity |
Early toxicity symptoms (1.5-2.0 mEq/L):
-Diarrhea -Vomiting -Drowsiness -Muscular weakness -Lack of coordination. Late toxicity symptoms (2.0 mEq/L or greater): -Ataxia -Giddiness -Blurred vision -Tinnitus -Large amount of dilute urine -Confusion -Coma -Death |
|
Antimanic Medications
|
Interactions:
Thiazide diuretics or drugs that decrease sodium levels will increase toxic effects of Lithium. Excessive salt intake, drugs containing large amounts of sodium, or ingestion of large amounts of caffeine decreases lithium levels. Combination of Haldol and Lithium can cause lethargy and confusion after high doses. |
|
Antimanic Medications
|
Contraindicated:
During pregnancy or breast feeding a baby. Lithium causes fetal abnormalities. If person has renal or cardiovascular disease. Use cautiously when person has thyroid disease or diabetes mellitus |
|
Antimanic Medications
Nursing Interventions/Teaching: |
Nursing Interventions/Teaching:
1. Inform patient of medication name, purpose, dosage, frequency, side effects, how to treat side effects, toxicity symptoms, call physician immediately if experiencing toxicity symptoms or if suspects pregnancy, compliancy, importance of regularly getting Lithium levels drawn, and what to do if a dose is missed. *See textbook for specific interventions for each side effect. 2. Encourage fluid intake of 2,500-3,000 ml/day to decrease chance of renal toxicity. Monitor that person does not increase water intake beyond 3,000 ml/day because fluid overload can cause a decrease in Lithium levels. 3. Monitor weight, intake, output, glucose, thyroid and renal function. 4. Assess diet. Encourage person to maintain balanced diet and salt intake since Lithium levels are related to sodium levels. The levels are inversely proportional. 5. Assess for diaphoresis, diarrhea, vomiting, fever, diuresis, or sodium changes. 6. Avoid driving until level is stabilized. |
|
Anticonvulsant Medications
|
Action: Unknown, transports amino acids across neuronal membranes, increases GABA, or inhibits sodium transport.
Effectiveness: May take 1-2 weeks to stabilize bipolar disorder. |
|
Anticonvulsant Medications Meds:
|
Meds:
Depakote (valproic acid) Tegretol (carbamazepine) Neurontin (gabapentin) Trileptal (oxcarbazepine) Lamictal (lamotrigine) Gabitril (tiagabine) Topamax (toprimate) |
|
Anticonvulsant Medications Meds:

Side Effects:
1. Dizziness 2. Drowsiness 3. HA 4. Nausea 5. Vomiting/GI upset 6. Rash especially with Lamictal 7. Hepatotoxicity with Depakote and Tegretol 8. Weight gain 9. Fatigue 10.Tremor |

Teaching:/intervention
1. Inform patient of medication name, purpose, dosage, frequency, side effects, how to treat side effects, compliancy, and what to do if a dose is missed. *See textbook for specific interventions for each side effect. When giving anticonvulsant meds to treat bipolar disorder, don’t teach seizures may occur if stopping the med. That is only if the patient is taking an anticonvulsant for seizure activity. 2. Patient should notify physician immediately if pregnant or is breast feeding a baby. 3. Advise not to stop medication abruptly. 4. Be cautious driving or operating heavy machinery especially while medication is being adjusted. 5. As medication stabilizes the mood swings, the chance for a successful suicide attempt increases. 6. Monitor Depakote and Tegretol serum levels for toxicity. Therapeutic Depakote level is 50-100 mcg/ml. Therapeutic Tegretol level is 6-12 mcg/ml. Monitor hepatic function for both medications. |
