Bipolar disorder is a mood disorder characterized by one or more episodes of mania or hypomania, often with a history of one or more major depressive episodes.1 It is a chronic illness with a course characterized by relapses and improvements or remissions. Mood episodes can be manic, depressed, or mixed. They can be separated by long periods of stability or can cycle... 

Bipolar disorders have been categorized into bipolar I disorder, bipolar II disorder, and bipolar disorder, not otherwise specified (NOS). Bipolar I disorder is characterized by one or more manic or mixed mood episodes. Bipolar II disorder is characterized by one or more major depressive episodes and at least one hypomanic episode. Hypomania is an abnormally and persistently elevated, expansive, or irritable mood, but not of sufficient severity to cause significant impairment in social or occupational function and does not require hospitalization. Most epidemiologic studies have looked at bipolar disorder of all types (bipolar I and bipolar II), or the bipolar spectrum, which includes all clinical conditions thought to be closely related to bipolar disorder. The lifetime prevalence of bipolar I disorder is estimated to be between 0.3% and 2.4%. The lifetime prevalence of bipolar II disorder ranges from 0.2% to 5%. When including the bipolar spectrum, the lifetime prevalence is between 3% and 6.5%.1... 

Bipolar disorder can be conceptualized as a continuum or spectrum of mood disorders and is not comprised solely of bipolar I disorder.9 They include four subtypes bipolar I (periods of major depressive, manic, and/or mixed episodes) bipolar II (periods of major depression and hypomania) cyclothymic disorder (periods of hypomanic episodes and depressive episodes that do not meet all criteria for diagnosis of a major depressive episode) and bipolar disorder, NOS. The defining feature of bipolar disorders is one or more manic or hypomanic episodes in addition to depressive episodes that are not caused by any medical condition, substance abuse, or other psychiatric disorder.1... 

Cyclothymic disorder is a chronic mood disturbance generally lasting at least 2 years (1 year in children and adolescents) and characterized by mood swings including periods of hypomania... 

Guidelines agree that when antidepressants must be used, they should be combined with a mood-stabilizing drug to reduce the risk of mood switch to hypomania or mania.17,41 The question of which antidepressant drugs are less likely to cause a mood switch is not resolved. Anecdotal reports suggested bupropion may be less likely to cause this effect, but systematic reviews have not supported this conclusion. Prevailing evidence recommends that tricyclic antidepressants be avoided.41,43... 

Hypomania Abnormal mood elevation that does not meet the criteria for mania. 

In clinical psychiatric terms, the affective disorders can be subdivided into unipolar and bipolar disorders. Unipolar depression is also known as psychotic depression, endogenous depression, idiopathic depression and major depressive disorder. Bipolar disorder is now recognised as being heterogeneous bipolar disorder I is equivalent to classical manic depressive psychosis, or manic depression, while bipolar disorder II is depression with hypomania (Dean, 2002). Unipolar mania is where periods of mania alternate with periods of more normal moods. Seasonal affective disorder (SAD) refers to depression with its onset most commonly in winter, followed by a gradual remission in spring. Some milder forms of severe depression, often those with an identifiable cause, may be referred to as reactive or neurotic depression. Secondary depression is associated with other illnesses, such as neuro-degenerative or cardiovascular diseases, and is relatively common. 

Changes in the sleep-wake cycle or light-dark cycle can precipitate episodes of mania or depression. Bright light therapy can be used for the treatment of winter depression and can precipitate hypomania, mania, or mixed episodes. 

Approximately 10% to 15% of adolescents with recurrent major depressive episodes subsequently have an episode of mania or hypomania. 

In addition to the above behavioral and performance tests, there are a number of well-known tests of personality that may provide useful information in select clinical studies. The most well known of these tests is the Minnesota Multiphasic Personality Inventory (MMPI). This test consists of 550 affirmative statements to which a true or false response is given and requires about one hour to complete. It is given to adults over the age of 16 and is scored for ten scales depression, hysteria, hypochondriasis, psychopathic deviate, masculinity-femininity, paranoia, hypomania, schizophrenia, psychasthenia, and social introversion. 

Hypomania and use with other antidepressants One case has been reported of concurrent use of hypericum with an SSRI. Gordon (1998) reported a case of a 50-year-old woman taking 600 mg/day of hypericum for chronic depression. She had discontinued taking Paxil 10 days prior to hypericum and experienced no ill effects at that time. However, she added 20 mg of paroxetine to her regimen of hypericum to improve her sleep. She presented with lethargy, nausea, and weakness, but vital signs and mental status were normal. Following discontinuation of medications, she returned to normal status the next day. 

Two cases of hypomania resulting from hypericum have been reported (O Breasail and Argouarch 1998). One case involved post-stroke depres-... 

The unipolar mood disorders consist solely of episodes of depression. On the other hand, the bipolar mood disorders consist of episodes of both depressed and elevated mood. The periods of elevated mood are characterized by either euphoria or irritability and are called mania or hypomania depending on the level of severity. A schematic of the mood disorders is shown in Figure 3.1. Substance-induced mood disorders and mood disorders due to general medical conditions usually manifest depressed mood however, manic episodes are occasionally seen as well. 

In the bipolar affective disorders (BPADs), periods of normal mood are interspersed with episodes of mania, hypomania, mixed states, or depression. BPAD differs from MDD in that there is a bidirectional natnre to the mood swings and, for many patients, the rate of cycling is more rapid in BPAD than MDD. The phases of BPAD inclnde mania, hypomania, and depression, though mixed states, the simultaneous presentation of symptoms of both mania and depression, are common. 

D. Unlike hypomania, the impairment is very severe and may require a hospital stay. 

Bipolar Syndromes. There are three distinct bipolar syndromes described in DSM-IV BRAD I, BRAD II, and cyclothymic disorder. The most severe subtype, BRAD I, is comprised of episodes of mania and/or depression. BRAD II, in contrast, is defined by episodes of hypomania and/or depression. BRAD II is arguably the most difficult to distinguish from the mood instability of patients with Cluster B personality disorders. Cyclothymic patients fluctuate between phases of hypomania and those of mild depression reminiscent of dysthymia. Although the symptoms of cyclothymia produce significant morbidity and impairment, the disability falls far... 

For this reason, the initial evaluation of a patient during an episode of mania or hypomania must include a review of all prescribed medications and illicit substance use, and collection of a urine drug screen. We must bear in mind, however, that many of the newer designer drugs such as Ecstasy are not typically detected by most commercial laboratory tests for drugs of abuse. 

In contrast to MDD, the bipolar disorders consist of episodes of depression and episodes of hypomania or mania. This poses a problem for treating the depressed phase of this illness, becanse, as noted earlier, antidepressants can trigger hypomania, mania, or mixed dysphoric mania and can increase the freqnency of manic episodes. Therefore, the hallmark of treating BPAD is the nse of mood stabilizers, with and withont snpplemental antidepressant therapy. Please refer to Table 3.16 for a comparison of the traditional mood stabilizers. 

Manic, Hypomanic, and Mixed Episodes. The first step in managing an acute episode of BPAD is to choose the appropriate venue for treatment. Even when the patient is not overtly suicidal, the agitation, disinhibition, and impulsivity inherent to a severe manic or mixed episode of the disorder commonly require hospitalization. Hypomania, however, can usually be managed outside the hospital with frequent outpatient visits. This is particularly true if the longitudinal course of the patient s illness indicates that the patient is unlikely to progress to a full-blown manic episode. 

Choice of a Mood Stabilizer. With the advance of atypical antipsychotics and an ever-expanding list of anticonvulsants, the number of medications reported to treat acute mania and hypomania continues to grow. In fact, all of the atypical antipsychotics, olanzapine, quetiapine, risperidone, ziprasidone, and aripiprazole have FDA approval for the treatment of acute mania. Long-term protection against future episodes of illness has also been demonstrated with several of these agents, which can influence the choice of initial therapy. 

For example, stimnlants can cause irritability. However, irritability can also resnlt from depression. So it is always important to rule out comorbid depression in the patient with ADHD before discontinuing the stimulant medication. If the irritability does resnlt from depression, then the obvious solution is to add an antidepressant to the stimnlant. Conversely, irritability can also be a symptom of emerging hypomania or mania. 

The diagnosis can be clarified by collecting a retrospective history both from the patient and from a collateral source, such as a friend or family member. A history of bipolar disorder will include episodes of illness that typically arise spontaneously, last for days or weeks, and often result in a decreased need for sleep during times of hypomania or mania. The periods of affective lability in the patient with a Cluster B personality generally do not arise in this spontaneous fashion but are instead triggered by a stressful life event. In addition, they seldom last as long as the typical...
