Chapter Six
Summary
Bipolar disorder is characterized by cycling between extreme highs or mania, and extreme lows or
depression. For some, the mania may be less intense and troublesome, so we refer to this as hypomania. While the
typical age of onset is about 19, it may be several years before a definitive diagnosis is made. Although effective
treatments are available, most patients will fail to maintain treatment protocol in the first five years.
In contrast to unipolar depression, bipolar depression is thought to be endogenously caused. It may
however, be triggered by exogenous stimuli. The concordance rates among monozygotic twins can be as high as
70%. In many cases, physicians and others fail to obtain adequate history and treat the more obvious depressive
symptoms first. This may trigger a manic or hypomanic episode.
Many other diseases have been known to cause or exacerbate mania. These include brain tumors, syphilis,
CNS trauma, delirium and dementia, hyperthyroidism, cancer, MS, Parkinson’s, hemodialysis, stroke, epilepsy, and
vitamin deficiencies just to name a few. Furthermore, drugs of abuse and other medications may cause manic type
symptoms. These include antihypertensives, antidepressants, cimetidine, steroids, disulfiriam, cocaine,
hallucinogens, PCP, opioids, and various stimulants.
Treatment of bipolar conditions can be tricky. Medications include mood stabilizers like lithium and other
anticonvulsants, but they may also include atypical antipsychotics . The choice of medication depends on which
phase of depression or mania the patient is exhibiting. Lithium is the “gold standard” as it may be used to control
both the manic and depressive aspects of the illness. Careful monitoring of lithium levels is essential to prevent toxic
levels, which is very close to the actual therapeutic level.
Specific Discussion Questions:
1. Explain the major differences between Bipolar Type I and II. How would a medication regime change to
address the differences?
2. Explain why Bipolar illness is thought to have a genetic predisposition.
3. Why is good patient education and family therapy so important when working with Bipolar patients?
4. Aside from anticonvulsants, which anti psychotics have been approved for treating manic symptoms?
5. Review the various steps of treatment based on the phase of the patient’s illness. When would one consider a
two or three-drug combination?
