Bipolar Disorder Essay, Research Paper
Bipolar Disorder The phenomenon of bipolar affective disorder has been a mystery since the 16th century. History has shown that this affliction can appear in almost anyone. Even the great painter Vincent Van Gogh is believed to have had bipolar disorder. It is clear that in our society many people live with bipolar disorder; however, despite the abundance of people suffering from the it, we are still waiting for definite explanations for the causes and cure. The one fact of which we are painfully awareis that bipolar disorder severely undermines its victims ability to obtain and maintain social and occupational success. Because bipolar disorder has such debilitating symptoms, it is imperative that we remain vigilant in the quest for explanations of its causes and treatment. Affective disorders are characterised by a smorgasbord of symptoms that can be broken into manic and depressive episodes. The depressive episodes are characterised by intense feelings of sadness and despair that can become feelings of hopelessness and helplessness. Some of the symptoms of a depressive episode include anhedonia, disturbances in sleep and appetite, psychomotor retardation, loss of energy, feelings of worthlessness, guilt, difficulty thinking, indecision, and recurrent thoughts of death and suicide (Hollandsworth, Jr. 1990). The manic episodes are characterised by elevated or irritable mood, increased energy, decreased need for sleep, poor judgement and insight, and often reckless or irresponsible behaviour (Hollandsworth, Jr. 1990). Bipolar affective disorder affects approximately one percent of the population (approximately three million people) in the United States. It is presented by both males and females. Bipolar disorder involves episodes of mania and depression. These episodes may alternate with profound depressions characterised by a pervasive sadness, almost inability to move, hopelessness, and disturbances in appetite, sleep, in concentrations and driving. Bipolar disorder is diagnosed if an episode of mania occurs whether depression has been diagnosed or not (Goodwin, Guze, 1989, p 11). Most commonly, individuals with manic episodes experience a period of depression. Symptoms include elated, expansive, or irritable mood, hyperactivity, pressure of speech, flight of ideas, inflated self esteem, decreased need for sleep, distractibility, and excessive involvement in reckless activities (Hollandsworth, Jr. 1990). Rarest symptoms were periods of loss of all interest and retardation or agitation (Weisman, 1991). As the National Depressive and Manic Depressive Association (MDMDA) has demonstrated, bipolar disorder can create substantial developmental delays, marital and family disruptions, occupational setbacks, and financial disasters. This devastating disease causes disruptions of families, loss of jobs, and millions of dollars in cost to society. Many time s bipolar patients report that the depressions are longer and increase in frequency as the individual ages. Many times s bipolar states and psychotic states are misdiagnosed as schizophrenia. Speech patterns help distinguish between the two disorders (Lish, 1994). The onset of Bipolar disorder usually occurs between the ages of 20 and 30 years of age, with a second peak in the mid-forties for women. A typical bipolar patient may experience eight to ten episodes in their lifetime. However, those who have rapid cycling may experience more episodes of mania and depression that succeed each other without a period of remission (DSM III-R). The three stages of mania begin with hypomania, in which patients report that they are energetic, extroverted and assertive (Hirschfeld, 1995). The hypomania state has led observers to feel that bipolar patients are “addicted” to their mania. Hypomania progresses into mania and the transition is marked by loss of judgement (Hirschfeld, 1995). Often, euphoric grandiose characteristics are displayed, and paranoid orirritable characteristics begin to manifest. The third stage of mania is evident when the patient experiences delusions with often paranoid themes. Speech is generally rapid and hyperactive behaviour manifests sometimes associated with violence (Hirschfeld, 1995). When both manic and depressive symptoms occur at the same time, it is called a mixed episode. Those afflicted are a special risk because there is a combination of hopelessness, agitation, and anxiety that makes them feel like they “could jump out of their skin”(Hirschfeld, 1995). Up to 50% of all patients with mania have a mixture of depressed moods. Patients report feeling dysphoric, depressed, and unhappy; yet,they exhibit the energy associated with mania. Rapid cycling mania is another presentation of bipolar disorder. Mania may be present with four or more distinct episodes within a 12-month period. There is now evidence to suggest that sometimes rapid cycling may be a transient manifestation of the bipolar disorder. This form of the disease exhibits more episodes of mania and depression than bipolar. Lithium has been the primary treatment of bipolar disorder since its introduction in the 1960’s. It is main function is to stabilise the cycling characteristic of bipolar disorder. In four controlled studies by F. K. Goodwin and K. R. Jamison, the overall response rate for bipolar subjects treated with Lithium was 78% (1990). Lithium is also the primary drug used for long- term maintenance of bipolar disorder. In a majority of bipolar patients, it lessens the duration, frequency, and severity of the episodes of both mania and depression. Unfortunately, as many as 40% of bipolar patients are either unresponsive to lithium or can not tolerate the side effects. Some of the side effects include thirst, weight gain, nausea, diarrhoea, and oedema. Patients who are unresponsive to lithium treatment are often those who experience dysphoric mania, mixed states, or rapid cycling bipolar disorder. One of the problems associated with lithium is the fact the long-term lithium treatment has been associated with decreased thyroid functioning in-patients with bipolar disorder. Preliminary evidence also suggest that hypothyroidism may actually lead to rapid cycling (Bauer et al., 1990). Another problem associated with the use of lithium is experienced by pregnant women. Its use during pregnancy has been associated with birth defects, particularly Ebstein’s anomaly. Based on current data, the risk of a child with Ebstein’s anomaly being born to a mother who took lithium during her first trimester of pregnancy is approximately 1 in 8,000, or 2.5 times that of the general population (Jacobson et al., 1992). There are other effective treatments for bipolar disorder that are used in cases where the patients cannot tolerate lithium or have been unresponsive to it in the past. The American Psychiatric Association’s guidelines suggest the next line of treatment to be Anticonvulsant drugs such as valproate and carbamazepine. These drugs are useful as
antimanic agents, especially in those patients with mixed states. Both of these medications can be used in combination with lithium or in combination with each other. Valproate is especially helpful for patients who are lithium noncompliant, experience rapid cycling, or have comorbid alcohol or drug abuse. Neuroleptics such as haloperidol or chlorpromazine have also been used to help stabilise manic patients who are highly agitated or psychotic. Use of these drugs is often necessary because the responses to them are rapid, but there are risks involved in their use. Because of the often severe side effects, Benzodiazepines are often used in their place. Benzodiazepines can achieve the same results as Neuroleptics for most patients in terms of rapid control of agitation and excitement, without the severe side effects. Antidepressants such as the selective serotonin reuptake inhibitors (SSRI s) fluovamine and amitriptyline have also been used by some doctors as treatment for bipolar disorder. A double-blind study by M. Gasperini, F. Gatti, L. Bellini, R.Anniverno, and E. Smeraldi showed that fluvoxamine and amitriptyline are highly effective treatments for bipolar patients experiencing depressive episodes (1992). This study is controversial however, because conflicting research shows that SSRI sand other antidepressants can actually precipitate manic episodes. Most doctors can see the usefulness of antidepressants when used in conjunction with mood stabilising medications such as lithium. In addition to the mentioned medical treatments of bipolar disorder, there are several other options available to bipolar patients, most of which are used in conjunction with medicine. One such treatment is light therapy. One study compared the response to light therapy of bipolar patients with that of unipolar patients. Patients were free ofpsychotropic and hypnotic medications for at least one month before treatment. Bipolar patients in this study showed an average of 90.3% improvement in their depressive symptoms, with no incidence of mania or hypomania. They all continued to use light therapy, and all showed a sustained positive response at a three month follow-up (Hopkins and Gelenberg, 1994). Another study involved a four week treatment of bright morning light treatment for patients with seasonal affectivedisorder and bipolar patients. This study found a statistically significant decrement in depressive symptoms, with the maximum antidepressant effect of light not being reached until week four (Baur, Kurtz, Rubin, and Markus, 1994). Hypomanic symptoms were experienced by 36% of bipolar patients in this study. Predominant hypomanic symptoms included racing thoughts, deceased sleep and irritability. Surprisingly, one-third of controls also developed symptoms such as those mentioned above. Regardless of the explanation of the emergence of hypomanic symptoms in undiagnosed controls, it is evident from this study that light treatment may be associated with the observed symptoms. Based on the results, careful professional monitoring during light treatment is necessary, even for those without a history of major mood disorders. Another popular treatment for bipolar disorder is electro-convulsive shock therapy. ECT is the preferred treatment for severely manic pregnant patients and patients who are homicidal, psychotic, catatonic, medically compromised, or severely suicidal. Inone study, researchers found marked improvement in 78% of patients treated with ECT, compared to 62% of patients treated only with lithium and 37% of patients who received neither, ECT or lithium (Black et al., 1987). A final type of therapy that I found is outpatient group psychotherapy. According to Dr. John Graves, spokesperson for The National Depressive and Manic Depressive Association has called attention to the value of support groups, and challenged mental health professionals to take a more serious look at group therapy for the bipolar population. Research shows that group participation may help increase lithium compliance, decrease denial regarding the illness, and increase awareness of both external and internal stress factors leading to manic and depressive episodes. Group therapy for patients with bipolar disorders responds to the need for support and reinforcement ofmedication management, and the need for education and support for the interpersonal difficulties that arise during the course of the disorder.
