Bipolar Disorder DefinitionBipolar, or manic-depressive disorder, is a mood disorder that causes radical emotional changes and mood swings, from manic highs to depressive lows. The majority of bipolar individuals experience alternating episodes of mania and depression. DescriptionIn the United States alone, more than two million people are diagnosed with bipolar disorder. Research shows that as many as 10 million people might be affected by bipolar disorder, which is the sixth-leading cause of disability worldwide. The average age of onset of bipolar disorder is from adolescence through the early twenties. However, because of the complexity of the disorder, a correct diagnosis can be delayed for several years or more. In a survey of bipolar patients conducted by the National Depressive and Manic Depressive Association (MDMDA), one-half of respondents reported visiting three or more professionals before receiving a correct diagnosis, and over one-third reported a wait of ten years or more before they were correctly diagnosed. Bipolar I disorder is characterized by manic episodes, the "high" of the manic-depressive cycle. A person with bipolar disorder experiencing mania often has feelings of self-importance, elation, talkativeness, increased sociability, and a desire to embark on goal-oriented activities, coupled with the characteristics of irritability, impatience, impulsiveness, hyperactivity, and a decreased need for sleep. Usually this manic period is followed by a period of depression, although a few bipolar I individuals may not experience a major depressive episode. Mixed states, where both manic or hypomanic symptoms and depressive symptoms occur at the same time, also occur frequently with bipolar I patients (for example, depression with the racing thoughts of mania). Also, dysphoric mania is common (mania characterized by anger and irritability). Bipolar II disorder is characterized by major depressive episodes alternating with episodes of hypomania, a milder form of mania. Bipolar depression may be difficult to distinguish from a unipolar major depressive episode. Patients with bipolar depression tend to have extremely low energy, retarded mental and physical processes, and more profound fatigue (for example, hypersomnia; a sleep disorder marked by a need for excessive sleep or sleepiness when awake) than unipolar depressives. Cyclothymia refers to the cycling of hypomanic episodes with depression that does not reach major depressive proportions. One-third of patients with cyclothymia will develop bipolar I or II disorder later in life. A phenomenon known as rapid cycling occurs in up to 20% of bipolar I and II patients. In rapid cycling, manic and depressive episodes must alternate frequently; at least four times in 12 months; to meet the diagnostic definition. In some cases of "ultra-rapid cycling," the patient may bounce between manic and depressive states several times within a 24-hour period. This condition is very hard to distinguish from mixed states. Bipolar NOS is a category for bipolar states that do not clearly fit into the bipolar I, II, or cyclothymia diagnoses. Causes and symptomsThe source of bipolar disorder has not been clearly defined. Because two-thirds of bipolar patients have a family history of affective or emotional disorders, researchers have searched for a genetic link to the disorder. Several studies have uncovered a number of possible genetic connections to the predisposition for bipolar disorder. A 2003 study found that schizophrenia and bipolar disorder could have similar genetic causes that arise from certain problems with genes associated with myelin development in the central nervous system. (Myelin is a white, fat-like substance that forms a sort of layer or sheath around nerve fibers.) Another possible biological cause under investigation is the presence of an excessive calcium build-up in the cells of bipolar patients. Also, dopamine and other neurochemical transmitters appear to be implicated in bipolar disorder and these are under intense investigation. Key termsAffective disorder — An emotional disorder involving abnormal highs and/or lows in mood. Now termed mood disorder. Anticonvulsant medication — A drug used to prevent convulsions or seizures; often prescribed in the treatment of epilepsy. Several anticonvulsant medications have been found effective in the treatment of bipolar disorder. Antipsychotic medication — A drug used to treat psychotic symptoms, such as delusions or hallucinations, in which patients are unable to distinguish fantasy from reality. Benzodiazpines — A group of tranquilizers having sedative, hypnotic, antianxiety, amnestic, anticonvulsant, and muscle relaxant effects. DSM-IV — Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). This reference book, published by the American Psychiatric Association, is the diagnostic standard for most mental health professionals in the United States. ECT — Electroconvulsive therapy sometimes is used to treat depression or mania when pharmaceutical treatment fails. Hypomania — A milder form of mania which is characteristic of bipolar II disorder. Mania — An elevated or euphoric mood or irritable state that is characteristic of bipolar I disorder. Mixed mania/mixed state — A mental state in which symptoms of both depression and mania occur simultaneously. Neurotransmitter — A chemical in the brain that transmits messages between neurons, or nerve cells. Changes in the levels of certain neurotransmitters, such as serotonin, norepinephrine, and dopamine, are thought to be related to bipolar disorder. Psychomotor retardation — Slowed mental and physical processes characteristic of a bipolar depressive episode. Over one-half of patients diagnosed with bipolar disorder have a history of substance abuse. There is a high rate of association between cocaine abuse and bipolar disorder. Some studies have shown up to 30% of abusers meeting the criteria for bipolar disorder. The emotional and physical highs and lows of cocaine use correspond to the manic depression of the bipolar patient, making the disorder difficult to diagnosis. For some bipolar patients, manic and depressive episodes coincide with seasonal changes. Depressive episodes are typical during winter and fall, and manic episodes are more probable in the spring and summer months. Symptoms of bipolar depressive episodes include low energy levels, feelings of despair, difficulty concentrating, extreme fatigue, and psychomotor retardation (slowed mental and physical capabilities). Manic episodes are characterized by feelings of euphoria, lack of inhibitions, racing thoughts, diminished need for sleep, talkativeness, risk taking, and irritability. In extreme cases, mania can induce hallucinations and other psychotic symptoms such as grandiose illusions. DiagnosisBipolar disorder usually is diagnosed and treated by a psychiatrist and/or a psychologist with medical assistance. In addition to an interview, several clinical inventories or scales may be used to assess the patient's mental status and determine the presence of bipolar symptoms. These include the Millon Clinical Multiaxial Inventory III (MCMI-III), Minnesota Multiphasic Personality Inventory II (MMPI-2), the Internal State Scale (ISS), the Self-Report Manic Inventory (SRMI), and the Young Mania Rating Scale (YMRS). The tests are verbal and/or written and are administered in both hospital and outpatient settings. Psychologists and psychiatrists typically use the criteria listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) as a guideline for diagnosis of bipolar disorder and other mental illnesses. DSM-IV describes a manic episode as an abnormally elevated or irritable mood lasting a period of at least one week that is distinguished by at least three of the mania symptoms: inflated self-esteem, decreased need for sleep, talkativeness, racing thoughts, distractibility, increase in goal-directed activity, or excessive involvement in pleasurable activities that have a high potential for painful consequences. If the mood of the patient is irritable and not elevated, four of the symptoms are required. Although many clinicians find the criteria too rigid, a hypomanic diagnosis requires a duration of at least four days with at least three of the symptoms indicated for manic episodes (four if mood is irritable and not elevated). DSM-IV notes that unlike manic episodes, hypomanic episodes do not cause a marked impairment in social or occupational functioning, do not require hospitalization, and do not have psychotic features. In addition, because hypomanic episodes are characterized by high energy and goal directed activities and often result in a positive outcome, or are perceived in a positive manner by the patient, bipolar II disorder can go undiagnosed. Bipolar symptoms often present differently in children and adolescents. Manic episodes in these age groups are typically characterized by more psychotic features than in adults, which may lead to a misdiagnosis of schizophrenia. Children and adolescents also tend toward irritability and aggressiveness instead of elation. Further, symptoms tend to be chronic, or ongoing, rather than acute, or episodic. Bipolar children are easily distracted, impulsive, and hyperactive, which can lead to a misdiagnosis of attention deficit hyperactivity disorder (ADHD). Furthermore, their aggression often leads to violence, which may be misdiagnosed as a conduct disorder. Substance abuse, thyroid disease, and use of prescription or over-the-counter medication can mask or mimic the presence of bipolar disorder. In cases of substance abuse, the patient must ordinarily undergo a period of detoxification and abstinence before a mood disorder is diagnosed and treatment begins. TreatmentTreatment of bipolar disorder is usually achieved with medication. A combination of mood stabilizing agents with antidepressants, antipsychotics, and anticonvulsants is used to regulate manic and depressive episodes. Mood stabilizing agents such as lithium, carbamazepine, and valproate are prescribed to regulate the manic highs and lows of bipolar disorder:
Treating the depression associated with bipolar disorder has proven more challenging. In early 2004, the first drug to treat bipolar administration was approved by the U.S. Food and Drug Administration (FDA). It is called Symbyax, a combination of olanzipine and fluoxetine, the active ingredient in Prozac. Because antidepressants may stimulate manic episodes in some bipolar patients, their use typically is short-term. Selective serotonin reuptake inhibitors (SSRIs) or, less often, monoamine oxidase inhibitors (MAO inhibitors) are prescribed for episodes of bipolar depression. Tricyclic antidepressants used to treat unipolar depression may trigger rapid cycling in bipolar patients and are, therefore, not a preferred treatment option for bipolar depression.
Adjunct treatments are used in conjunction with a long-term pharmaceutical treatment plan:
Clozapine (Clozaril) is an atypical antipsychotic medication used to control manic episodes in patients who have not responded to typical mood stabilizing agents. The drug has also been a useful prophylactic, or preventative treatment, in some bipolar patients. Common side effects of clozapine include tachycardia (rapid heart rate), hypotension, constipation, and weight gain. Agranulocytosis, a potentially serious but reversible condition in which the white blood cells that typically fight infection in the body are destroyed, is a possible side effect of clozapine. Patients treated with the drug should undergo weekly blood tests to monitor white blood cell counts. Risperidone (Risperdal) is an atypical antipsychotic medication that has been successful in controlling mania when low doses were administered. In early 2004, the FDA approved its use for treating bipolar mania. The side effects of risperidone are mild compared to many other antipsychotics (constipation, coughing, diarrhea, dry mouth, headache, heartburn, increased length of sleep and dream activity, nausea, runny nose, sore throat, fatigue, and weight gain). Olanzapine (Zyprexa) is another atypical antipsychotic approved in 2003 for use in combination with lithium or valproate for treatment of acute manic episodes associated with bipolar disorder. Side effects include hypotension (low blood pressure) associated with dizziness, rapid heartbeat, and syncope, or low blood pressure to the point of fainting. Lamotrigine (Lamictal, or LTG), an anticonvulsant medication, was found to alleviate manic symptoms in a 1997 trial of 75 bipolar patients. The drug was used in conjunction with divalproex (divalproate) and/or lithium. Possible side effects of lamotrigine include skin rash, dizziness, drowsiness, headache, nausea, and vomiting. Alternative treatmentGeneral recommendations include maintaining a calm environment, avoiding overstimulation, getting plenty of rest, regular exercise, and proper diet. Chinese herbs may soften mood swings. Biofeedback is effective in helping some patients control symptoms such as irritability, poor self control, racing thoughts, and sleep problems. A diet low in vanadium (a mineral found in meats and other foods) and high in vitamin C may be helpful in reducing depression. A surprising study in 2004 found that a rarely used combination of magnetic fields used in magnetic resonance imaging (MRI) scanning improved the moods of subjects with bipolar disorder. The discovery was made while scientists were using MRI to investigate effectiveness of certain medications. However, they found that a particular type of echo-planar magnetic field led to reports of mood improvement. Further studies may one day lead to a smaller, more convenient use of magnetic treatment. PrognosisWhile most patients will show some positive response to treatment, response varies widely, from full recovery to a complete lack of response to all drug and/or ECT therapy. Drug therapies frequently need adjustment to achieve the maximum benefit for the patient. Bipolar disorder is a chronic recurrent illness in over 90% of those afflicted, and one that requires lifelong observation and treatment after diagnosis. Patients with untreated or inadequately treated bipolar disorder have a suicide rate of 15-25% and a nine-year decrease in life expectancy. With proper treatment, the life expectancy of the bipolar patient will increase by nearly seven years and work productivity increases by ten years. PreventionThe ongoing medical management of bipolar disorder is critical to preventing relapse, or recurrence, of manic episodes. Even in carefully controlled treatment programs, bipolar patients may experience recurring episodes of the disorder. Patient education in the form of psychotherapy or self-help groups is crucial for training bipolar patients to recognize signs of mania and depression and to take an active part in their treatment program.

bipolar disorder, a major mental disorder characterized by episodes of mania, depression, or mixed mood. One or the other phase may be predominant at any given time, one phase may appear alternately with the other, or elements of both phases may be present simultaneously. Characteristics of the manic phase are excessive emotional displays, such as excitement, elation, euphoria, or in some cases irritability accompanied by hyperactivity, boisterousness, impaired ability to concentrate, decreased need for sleep, and seemingly unbounded energy. In extreme mania, a sense of omnipotence and delusions of grandeur may occur. In the depressive phase, marked apathy and underactivity are accompanied by feelings of profound sadness, loneliness, guilt, and lowered self-esteem. Causes of the disorder are multiple and complex, often involving biologic, psychologic, interpersonal, and social and cultural factors. The disorder is a biologic illness that can be precipitated or exacerbated by psychosocial stressors.

Bipolar disorder
Patient discussion about Manic-depressive mental disorder. Q. bipolar people, anyone else feels nothing or is it just me? I mean actually nothing, no meaning to anything, nothing make sense. emptyness A. I also wanted to say that the world like everything else is what it is. It is not an issue of being true or untrue, it just is. The world spins the seasons come and go and people are people, etc... It all just is. Like Joseph said the glass is not half full or half empty it is just a glass. Its a glass with water in it. You can fill the glass and empty the glass but it is still just a glass and when that glass is empty it is just as capable of being full again. I care, stay safe. Q. bipolar amnesia? I am 39 yrs old and suffer from Bipolar Disorder. Last March I suffered from a severe depressive episode and was hospitalized. Since I was 19yrs old, I have been hospitalized 3 times. Each time I suffered from a weird kind of amnesia. I don't recall long periods of time while I was falling into this depressive state. It is pretty unnerving. Anyone ever experience this type of amnesia and how do you cope? It is scarey to not remember some pretty significant times-- my husband will bring up things that I have no recollection of. Any help or support will be greatly appreciated. A. Is it just times that you were hospitalized that you have memory loss of? Or does that include time spent outside of the hospital? I know that there are medications specifically designed to make you forget about particualrily difficult times. My mother was given a medication after an invasive surgery to make her forget the extream pain she was experiencing. She has no memory to this day of the few days following the opporation. If you also experience this memory loss during times you are not hospitalized it may be your mind blocking out memories that were tramatic for you or side effects to medications you were on at the time. It is also possible you were experiencing psychosis in those times. Often psychosis comes with blackouts. Q. I am scared of bipolar disorder. I have noticed some changes in my behavior few months back, I am scared of bipolar disorder. So please let me know the symptoms of Bipolar disorder? A. Lixurion is right here, It is vey important to find a good doctor. I have found that GP's (family doctors) are great for colds or stomach aches but when it comes to mental illness they do not know enough to be of sufficiant help to you. Ask to be referred to a psychiatrist, in fact I would ask for a few names you have to find someone you trust. Read more or ask a question about Manic-depressive mental disorderYour fear is based on a lack of knowlege about bipolar disorder, once you learn the facts about the illness you will no longer fear the illness. there are ways to manage this illness. Start with an accurate diagnosis and move forward to educate yourself as much as possible about the illness, its symptoms and treatments. I will be thinking of you in this time. The symptoms are as follows: mania- irritable, spending money, excessive energy, lack of sleep or the need to sleep etc... Depression- over sleeping, inability to function, lack of interest in thigs you were once important to you, thoughts/planning of suicide.. How to thank TFD for its existence?
