OverviewBipolar disorder, or manic-depressive illness
(MDI), is one of the most common, severe, and persistent mental illnesses
Bipolar disorder is characterized by periods of deep, prolonged, and profound depression that alternate with periods of an excessively elevated or irritable mood known as mania.
Bipolar disorder constitutes 1 pole of a spectrum of mood disorders that includes including bipolar I (BPI), bipolar II (BPII), cyclothymia, and major depression.

PathophysiologyThe pathophysiology of bipolar disorder has
not been determined, and no objective biologic markers correspond definitively with the disease state. However, twin, family, and adoption studies all indicate that bipolar disorder has a genetic component.

GENETICBPI, has a major genetic component, with the
involvement of the ANK3,CACNA1C, and CLOCK genes
A parent with bipolar disorder have a 50% chance of having another major psychiatric disorder
Twin studies demonstrate a concordance of 33-90% for BPI in identical twins.

BIOCHEMICAL1. A number of neurotransmitters have been
linked to this disorder, largely based on patients’ responses to psychoactive agents.
2.Drugs like cocaine, which also act on this neurotransmitter system, exacerbate mania
3.Hormonal imbalances and disruptions of the hypothalamic-pituitary-adrenal axis involved in homeostasis and the stress response may also contribute to the clinical picture of bipolar disorder.
4.Tricyclic antidepressants can trigger mania.

EpidemiologyThe lifelong prevalence of bipolar disorder
in the United States has been noted to range from 1% to 1.6%.
The age of onset of bipolar disorder varies greatly. Most cases commence when individuals are aged 15-19 years. The second most frequent age range of onset is 20-24 years.
BP I occurs equally in both sexes. The incidence of BPII is higher in females than in males.

HistoryThese criteria are based on the
specifications of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR).

Prognosis Factors suggesting a worse prognosis include the
following:Poor job historyAlcohol abusePsychotic featuresDepressive features between periods of mania and
depressionEvidence of depressionMale sex
Factors suggesting a better prognosis include the following:Manic phases (short in duration)Late age of onsetFew thoughts of suicideFew psychotic symptomsFew medical problems

Physical ExaminationUse the Mental Status Examination (MSE)
to diagnose bipolar disorder. This section highlights the major findings for a person with bipolar disorder. Because the patient’s mental status depends on whether he or she is depressed, hypomanic, manic, or mixed, the following discussions of the various areas of the MSE include consideration of each of these particular phases
![Page 15: Journal Presentation Bipolar Affective Disorder](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f1cf0b1af9f880b8b4ef4/html5/thumbnails/15.jpg)
AppearancePersons experiencing a depressed episode
may demonstrate poor to no eye contact.Persons experiencing a hypomanic episode
are busy, active, and involved. a patient in the manic phase is the
opposite of that of a person in the depressed phase. Patients experiencing the manic phase are hyperactive and might be hypervigilant.
![Page 16: Journal Presentation Bipolar Affective Disorder](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f1cf0b1af9f880b8b4ef4/html5/thumbnails/16.jpg)
Affect/moodIn persons experiencing a depressed
episode, sadness dominates the affect. In persons experiencing a hypomanic
episode, the mood is up, expansive, and often irritable.
In persons experiencing a manic episode, the mood is inappropriately joyous, elated, and jubilant.
![Page 17: Journal Presentation Bipolar Affective Disorder](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f1cf0b1af9f880b8b4ef4/html5/thumbnails/17.jpg)
Perceptions Persepsi Patients experiencing a hypomanic episode do
not experience perceptual disturbances. Approximately three fourths of patients
experiencing a manic episode have delusions. Manic delusions reflect perceptions of power, prestige, position, self-worth, and glory.
Patients experiencing a mixed episode might exhibit delusions and hallucinations consistent with either depression or mania or congruent to both.
![Page 18: Journal Presentation Bipolar Affective Disorder](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f1cf0b1af9f880b8b4ef4/html5/thumbnails/18.jpg)
Suicide/self-destructionPatients experiencing a depressed episode
have a very high rate of suicide. Patients experiencing a hypomanic or manic episode have a low incidence of suicide.
Homicide/violence/aggression Patients who are hypomanic frequently show
evidence of irritability and aggressiveness. Persons experiencing a manic episode can be
openly combative and aggressive. The homicidal element is particularly likely to
emerge if these individuals have a delusional content to their mania.
![Page 19: Journal Presentation Bipolar Affective Disorder](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f1cf0b1af9f880b8b4ef4/html5/thumbnails/19.jpg)
Judgment/insight Persons experiencing a hypomanic episode
generally have good but expansive judgment.
In patients experiencing a manic episode, judgment is seriously impaired.
CognitionImpairments in orientation and memory are
seldom observed in patients with bipolar disorder unless they are very psychotic.

ComplicationsThe main complications of bipolar disorder
are suicide, homicide, and addictions.
![Page 21: Journal Presentation Bipolar Affective Disorder](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f1cf0b1af9f880b8b4ef4/html5/thumbnails/21.jpg)
TreatmentPropose a regular exercise schedule for all
patients, especially those with bipolar disorder. Both the exercise and the regular schedule are keys to surviving this illness.
The indications for inpatient treatment in a person with bipolar disorder include the following:Danger to selfDanger to othersTotal inability to functionTotal loss of controlMedical conditions that warrant medication monitoring
![Page 22: Journal Presentation Bipolar Affective Disorder](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f1cf0b1af9f880b8b4ef4/html5/thumbnails/22.jpg)
Outpatient treatment has 4 major goals, as follows.
1.Look at areas of stress and find ways to handle them.
2.Monitor and support the medication. 3.Develop and maintain the therapeutic
alliance. 4.Provide education.

Pharmacologic TherapyAppropriate medication depends on the stage of
the bipolar disorder the patient is experiencing
Electroconvulsive Therapy ECT is useful in a number of instances. It has
proven to be highly effective in the treatment of acute mania. Often, the severity of the symptoms, the lack of response to medications, or the presence of contraindications to certain medications necessitates the use of ECT. In a study of 400 patients with acute mania who received ECT, 313 showed significant clinical improvement.

“Pharmacologic Therapy”-Mood stabilizersLithium is the drug commonly used for
prophylaxis and treatment of manic episodes. -AnticonvulsantsAnticonvulsants have been effective in preventing
mood swings associated with bipolar disorder, especially in those patients known as rapid cyclers.
-Atypical AntipsychoticsAtypical antipsychotics are being used
increasingly for treatment of both acute mania and mood stabilization.
