Bipolar Disorder (DSM-IV-TR #296.0–296.89)
Bipolar disorder is characterized by the occurrence of at least occurrence of gradual transitions between all the various one manic or mixed-manic episode during the patient’s states.” In a similar vein, Carlson and Goodwin, in their lifetime. Most patients also, at other times, have one or more elegant paper of 1973, divided a manic episode into “three depressive episodes. In the intervals between these episodes, stages”: hypomania, or stage I; acute mania, or stage II; and most patients return to their normal state of well-being. Thus delirious mania, or stage III. As this “staging” of a manic bipolar disorder is a “cyclic” or “periodic” illness, with episode is very useful from a descriptive and differential patients cycling “up” into a manic or mixed-manic episode, diagnostic point of view, it is used in this chapter. Thus, then returning to normal, and cycling “down” into a when the term “manic episode” is used it may refer to any depressive episode from which they likewise eventually more one of the three stages of mania: hypomania, acute mania, or Bipolar disorder is probably equally common among men Manic episodes are often preceded by a prodrome, lasting and women and has a lifetime prevalence of from 1.3 to from a few days to a few months, of mild and often transitory and indistinct manic symptoms. At times, however, no prodromal warning signs may occur, and the episode starts quite abruptly. When this occurs, patients often Bipolar disorder in the past has been referred to as “manic unaccountably wake up during the night full of energy and depressive illness, circular type.” As noted in the introduction vigor—the so-called “manic alert.” to the chapter on major depression, the term “manic depressive illness,” at least in the United States, has more and more come to be used as equivalent to bipolar disorder. As The cardinal symptoms of mania are the following: this convention, however, is not worldwide, the term heightened mood (either euphoric or irritable); flight of ideas “bipolar” may be better, as it clearly indicates that the patient and pressure of speech; and increased energy, decreased need has an illness characterized by “swings” to the manic “pole” for sleep, and hyperactivity. These cardinal symptoms are and generally also to the depressive “pole.” most plainly evident in hypomania. In acute mania they exacerbate and may be joined by delusions and some fragmentation of behavior, and in delirious mania only tattered scraps of the cardinal symptoms may be present, otherwise being obscured by florid and often bizarre Bipolar disorder may present with either a depressive or a psychotic symptoms. Although all patients experience a manic episode, and the peak age of onset for the first episode, hypomanic stage, and almost all progress to at least a touch whether depressive or manic, lies in the teens and early of acute mania, only a minority finally are propelled into twenties. Earlier onsets may occur; indeed some patients may delirious mania. The rapidity with which patients pass from have their first episode at 10 years of age or younger.

The duration of an entire manic episode varies from the extremes of as little as a few days or less to many years, and rarely Premorbidly, these patients may either be normal or display even to a decade or more. On the average, however, most mild symptoms for a variable period of time before the first first episodes of mania last from several weeks up to 3 months.

The nosology of the various stages of a manic episode has In hypomania the mood is heightened and elevated. Most changed over the decades. In current DSM-IV nomenclature, often these patients are euphoric, full of jollity and hypomanic episodes are separated from the more severe full cheerfulness.

This flight of ideas is often accompanied by pressure of thought. Patients may report that their thoughts race, that severe exacerbation of the symptoms seen in hypomania, and they have too many thoughts, that they run on pell-mell. the appearance of delusions. Typically, the delusions are grandiose: millions of dollars are held in trust for them; Typically, patients also display pressure of speech. Here the listener is deluged with a torrent of words.

Impulses come at cross sick and impaired; if only the rest of the world could feel as purposes, and patients, though increasingly active, may be unable to complete anything.

On the average, untreated, these bipolar depressions tend to last about a half year. Hyperactivity is extreme, and behavior disintegrates into numerous and disparate fragments of purposeful activity.

These mixed-manic episodes must be distinguished from the transitional periods that may Patients may lose interest in life; things appear dull and appear in patients who “cycle” directly from a manic into a depressive episode, or vice versa, without any intervening euthymic interval. These transitional periods are often Many patients feel a greatly increased need for sleep. Some marked by an admixture of both manic and depressive may succumb and sleep 10, 14, or 18 hours a day. Yet no symptoms; however, they do not “stand alone” as episodes of matter how much sleep they get, they awake exhausted, as if illness unto themselves, but are always both immediately they had not slept at all.

In Conversely, some patients may experience insomnia or loss contrast the mixed-manic episode “stands alone.” It starts with mixed symptoms, endures with them, and finishes with them, and is neither immediately preceded nor immediately followed by an episode of mania or by an episode of Psychomotor retardation is the rule, although some patients may show agitation. In psychomotor retardation the patient may lie in bed or sit in the chair for hours, perhaps all day, profoundly apathetic and scarcely moving at all.

With time, however, the duration of the euthymic interval Mixed-manic episodes are not as common as manic episodes or depressive episodes, but tend to last longer.

Such “unipolar manic” patients are very Suicide occurs in from 10 to 20% of patients with bipolar rare. In general, a depressive preponderance is more common disorder and appears to be more common in those who have only hypomanic episodes (i.e., those with bipolar II disorder) than in those whose manic episodes progress beyond the first stage (i.e., those with bipolar I disorder). Although most As noted earlier, for most patients the interval between suicides appear to occur during episodes of depression, episodes is euthymic and free of symptoms. In at least a patients in a mixed-manic episode may be at an even higher quarter of all cases, however, the interval may be “colored” by very mild symptoms, and the direction of this “coloring,” or its “polarity,” correlates with the preponderance of episodes. For example, a patient with very mild The complications of a depressive episode are as outlined in subhypomanic symptoms during the interval is likely to have more manic episodes than depressive ones, and the converse holds true for the patients whose interval is clouded with ETIOLOGY

DIFFERENTIAL DIAGNOSIS

In distinguishing bipolar disorder from other disorders, the single most useful differential feature is the course of the illness. Essentially no other disorder left untreated presents The differential between a postpartum psychosis and a with recurrent episodes of mood disturbance at least one of bipolar disorder that has become “entrained” to the which is a manic episode, with more or less full restitution to postpartum period is discussed in that chapter. normal functioning between episodes. Thus if the patient in question has had previous episodes and if the available history is complete, then one can generally state with The persistence of very mild affective symptoms between certainty whether the patient has bipolar disorder. However, episodes might suggest, depending on the polarity of the symptoms, a diagnosis of dysthymia or of hyperthymia. Here, these are two big “ifs,” and in clinical practice history may either be absent or unobtainable, and herein arises diagnostic however, temporal continuity of these symptoms with a full episode of illness betrays their true nature, that of either a prodrome or of a condition of only partial remission of a prior episode. Occasionally a patient in a manic episode is brought to the emergency room by police with no other history except that he was arrested for disturbing the peace.

If the The overall treatment of bipolar disorder is conveniently patient is in the stage of delirious mania, the differential approached by considering, in turn, the treatment of the would include an acute exacerbation of catatonic manic or mixed-manic episode first, then the treatment of the schizophrenia and also a delirium from some other cause. depressive episode, in each instance considering three phases The quality of the hyperactivity seen in the excited subtype of treatment: acute, continuation, and preventive.

Although there are no hard and fast rules for choosing among these agents, some general guidelines may be offered. Certainly, if the patient The distinction between secondary mania and a manic has a history of an excellent response to a particular agent, episode of bipolar disorder is discussed in that chapter. then it should be seriously considered.

In many When breakthrough mania occurs despite normal thyroid patients even though the dose of lithium is held constant, the status and good compliance, consideration may be given to blood level rises when the manic symptoms eventually come switching to monotherapy with another mood stabilizer or to under complete control. The unexpected appearance of side using a combination of mood stabilizers such as lithium plus effects to lithium may indicate this and should prompt a divalproex or lithium plus carbamazepine.

Clearly, if alternative to a mood stabilizer. It must be borne in mind, the patient is having breakthrough manic symptoms, no however, that, as compared with the mood stabilizers, matter how mild, treatment should continue.

If lithium was utilized, it is important to taper the dose over a few weeks time, as it appears that abrupt discontinuation of As noted in the section on course, various pharmacologic lithium predisposes to a recurrence of mania. Although the conditions, such as the use of sympathomimetics, the abrupt discontinuation of long-term treatment with clonidine, and Other Treatment Considerations

With regard to breast antidepressant or consider adding lamotrigine or perhaps feeding, no firm advice can be given: although maternal use topiramate. Traditionally an antidepressant has been used; of lithium, valproate and carbamazepine have all been rarely however, though effective, all the antidepressants entail the associated with adverse effects in breast-fed infants, large, risk of precipitating a manic episode; a strategy for choosing controlled studies are lacking. Consequently the decision to and utilizing an antidepressant is discussed in the chapter on breast feed or not should be made in light of the entire major depression. Neither lamotrigine nor topiramate carry a clinical picture, including the mother’s illness and response risk of inducing a manic episode, and between the two, the evidence for the effectiveness of lamotrigine is much stronger. In mild cases of depression, one may also consider the use of cognitive-behavioral therapy. Substance Use.
Continuation Treatment.
As noted earlier, alcohol abuse or alcoholism and cocaine addiction are not infrequently associated with bipolar disorder, and these must also be treated. Once the depressive symptoms are relieved, treatment should be continued until the patient has been asymptomatic for a significant period of time. If an antidepressant were added to a mood stabilizer, one should probably consider discontinuing the antidepressant after the patient has been BIBLIOGRAPHY
asymptomatic for a matter of months. Given the ongoing risk of a “precipitated” mania, it is preferable to discontinue the Baumann B, Bogerts B.
