Bipolar Disorders
Bipolar disorder is a mental illness characterized by periods of depression and periods of elevated mood. The elevated mood is significant and is known as mania or hypomania depending on its severity or whether symptoms of psychosis are present. During mania an individual behaves or feels abnormally energetic, happy or irritable. Individuals often make poorly thought out decisions with little regard to the consequences.
The need for sleep is usually reduced during manic phases as well.
During periods of depression there may be crying, a negative outlook on life, and poor eye contact with others.
The risk of suicide among those with the illness is high at greater than 6% over 20 years, while self-harm occurs in 30-40%. Other mental health issues such as anxiety disorder and substance use disorder are commonly associated.

About Bipolar Disorders
The cause is not clearly understood, but both environmental and genetic factors play a role. Many genes of small effect contribute to risk. Environmental factors include a history of childhood abuse and long term stress. It is divided into bipolar I disorder if there is at least one manic episode and bipolar II disorder if there are at least one hypomanic episode and one major depressive episode.
In those with less severe symptoms of a prolonged duration the condition cyclothymic disorder may be present.
If due to drugs or medical problems it is classified separately.
Other conditions that may present in a similar manner include attention deficit hyperactivity disorder, personality disorders, schizophrenia and substance use disorder as well as a number of medical conditions. Medical testing is not required for a diagnosis.
However, blood tests or medical imaging can be done to rule out other problems.
Treatment commonly includes psychotherapy, as well as medications such as mood stabilizers and antipsychotics. Examples of mood stabilizers that are commonly used include lithium and anticonvulsants. Treatment in hospital against a person’s consent may be required at times as people may be a risk to themselves or others yet refuse treatment. Severe behavioral problems may be managed with short term antipsychotics or benzodiazepines. In periods of mania it is recommended that antidepressants be stopped. If antidepressants are used for periods of depression they should be used with a mood stabilizer.
Electric shock therapy may be helpful for those who do not respond to other treatments. If treatments are stopped, it is recommended that this be done slowly.
Many individuals have financial, social or work-related problems due to the illness. These difficulties occur a quarter to a third of the time on average. The risk of death from natural causes such as heart disease is twice that of the general population. This is due to poor lifestyle choices and the side effects from medications.
About 1% of people around the world are estimated to have bipolar disorder at some point in their life. The most common age at which symptoms begin is 25.
Rates appear to be similar in females as males. People with bipolar disorder often face problems with social stigma.

Mania is the defining feature of bipolar disorder, and can occur with different levels of severity. With milder levels of mania, known as hypomania, individuals appear energetic, excitable, and may be highly productive.
As mania worsens, individuals begin to exhibit erratic and impulsive behaviour, often making poor decisions due to unrealistic ideas about the future, and sleep very little.
At the most severe level, manic individuals can experience very distorted beliefs about the world known as psychosis.
A depressive episode commonly follows an episode of mania.
The biological mechanisms responsible for switching from a manic or hypomanic episode to a depressive episode or vice versa remain poorly understood.
The causes of bipolar disorder likely vary between individuals and the exact mechanism underlying the disorder remains unclear. Genetic influences are believed to account for 60–80% of the risk of developing the disorder indicating a strong hereditary component.
The overall heritability of the bipolar spectrum has been estimated at 0.71.
Twin studies have been limited by relatively small sample sizes but have indicated a substantial genetic contribution, as well as environmental influence.
For bipolar disorder type I, the (probandwise) concordance rates in modern studies have been consistently estimated at around 40% in identical twins (same genes), compared to about 5% in fraternal twins. A combination of bipolar I, II and cyclothymia produced concordance rates of 42% vs. 11%, with a relatively lower ratio for bipolar II that likely reflects heterogeneity.
There is overlap with unipolar depression and if this is also counted in the co-twin the concordance with bipolar disorder rises to 67% in monozygotic twins and 19% in dizygotic. The relatively low concordance between dizygotic twins brought up together suggests that shared family environmental effects are limited, although the ability to detect them has been limited by small sample sizes.
Prevention of bipolar has focused on stress (such as childhood adversity or highly conflictual families) which, although not a diagnostically specific causal agent for bipolar, does place genetically and biologically vulnerable individuals at risk for a more pernicious course of illness. There has been debate regarding the causal relationship between usage of cannabis and bipolar disorder.
Bipolar disorder often goes unrecognized and is commonly diagnosed during adolescence or early adulthood. The disorder can be difficult to distinguish from unipolar depression and the mean delay in diagnosis is 5–10 years after symptoms begin.
Diagnosis of bipolar disorder takes several factors into account and considers the self-reported experiences of the symptomatic individual, behaviour abnormalities reported by family members, friends or co-workers, and observable signs of illness as assessed by a psychiatrist, nurse, social worker, clinical psychologist or other health professional. Assessment is usually done on an outpatient basis; admission to an inpatient facility is considered if there is a risk to oneself or others.
The most widely used criteria for diagnosing bipolar disorder are from the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, the current version being DSM-IV-TR, and the World Health Organization’s International Statistical Classification of Diseases and Related Health Problems, currently the ICD-10. The latter criteria are typically used in Europe and other regions while the DSM criteria are used in the USA and other regions, as well as prevailing in research studies. The DSM-V, published in 2013, included further and more accurate sub-typing
An initial assessment may include a physical exam by a physician. Although there are no biological tests that are diagnostic of bipolar disorder, tests may be carried out to exclude medical illnesses with clinical presentations similar to that of bipolar disorder such as hypothyroidism or hyperthyroidism, metabolic disturbance, a chronic disease, or an infection such as HIV or syphilis. An EEG may be used to exclude a seizure disorder such as epilepsy, and a CT scan of the head may be used to exclude brain lesions. Investigations are not generally repeated for a relapse unless there is a specific medical indication.
Several rating scales for the screening and evaluation of bipolar disorder exist, such as the Bipolar spectrum diagnostic scale. The use of evaluation scales can not substitute a full clinical interview but they serve to systematize the recollection of symptoms.

Bipolar spectrum disorders (BSD) include the following four disorders: bipolar I disorder, bipolar II disorder, cyclothymic disorder, and bipolar disorder not otherwise specified. These disorders typically involve depressive symptoms or episodes that alternate with elevated mood states or with mixed episodes that feature symptoms of both depressive and elevated mood states. The concept of the bipolar spectrum is similar to that of Emil Kraepelin’s original concept of manic depressive illness.
Unipolar hypomania without accompanying depression has been noted in the medical literature. There is speculation as to whether this condition may occur with greater frequency in the general, untreated population; successful social function of these potentially high-achieving individuals may lead to being labeled as normal, rather than as individuals with substantial dysregulation.

There is no clear consensus as to how many types of bipolar disorder exist. In DSM-IV-TR and ICD-10, bipolar disorder is conceptualized as a spectrum of disorders occurring on a continuum. The DSM-IV-TR lists three specific subtypes and one for non-specified:

Bipolar I disorder:
– At least one manic episode is necessary to make the diagnosis
– depressive episodes are common in bipolar disorder I, but are unnecessary for the diagnosis.
There are several other mental disorders with symptoms similar to those seen in bipolar disorder. These disorders include schizophrenia, major depressive disorder, attention deficit hyperactivity disorder (ADHD), and certain personality disorders, such as borderline personality disorder.
It has been noted that the bipolar disorder diagnosis is officially characterized in historical terms such that, technically, anyone with a history of (hypo)mania and depression has bipolar disorder whatever their current or future functioning and vulnerability. This has been described as “an ethical and methodological issue”, as it means no one can be considered as being recovered (only “in remission”) from bipolar disorder according to the official criteria. This is considered especially problematic given that brief hypomanic episodes are widespread among people generally and not necessarily associated with dysfunction.
There are a number of pharmacological and psychotherapeutic techniques used to treat bipolar disorder. Individuals may use self-help and pursue recovery.
Hospitalization may be required especially with the manic episodes present in bipolar I. Long-term inpatient stays are now less common due to deinstitutionalization, although these can still occur. Following (or in lieu of) a hospital admission, support services available can include drop-in centers, visits from members of a community mental health team or an Assertive Community Treatment team, supported employment and patient-led support groups, intensive outpatient programs. These are sometimes referred to as partial-inpatient programs.
For many individuals with bipolar disorder a good prognosis results from good treatment, which, in turn, results from an accurate diagnosis.
Of the various forms of bipolar disorder, rapid cycling bipolar disorder is associated with the worst prognosis.
Because bipolar disorder can have a high rate of both under-diagnosis and misdiagnosis, it is often difficult for individuals with the condition to receive timely and competent treatment. It can be a severely disabling medical condition. However, many individuals with bipolar disorder can live full and satisfying lives.
Quite often, medication is needed to enable this.
Persons with bipolar disorder may have periods of normal or near normal functioning between episodes.
A naturalistic study from first admission for mania or mixed episode (representing the hospitalized and therefore most severe cases) found that 50% achieved syndromal recovery (no longer meeting criteria for the diagnosis) within six weeks and 98% within two years.
Within two years, 72% achieved symptomatic recovery (no symptoms at all) and 43% achieved functional recovery (regaining of prior occupational and residential status). However, 40% went on to experience a new episode of mania or depression within 2 years of syndromal recovery, and 19% switched phases without recovery.
Symptoms preceding a relapse (prodromal), specially those related to mania, can be reliably identified by people with bipolar disorder.
There have been intents to teach patients coping strategies when noticing such symptoms with encouraging results.
Bipolar disorder can cause suicidal ideation that leads to suicidal attempts.
Individuals whose bipolar disorder begins with a depressive or mixed affective episode seem to have a poorer prognosis and an increased risk of suicide.
One out of two people with bipolar disorder attempt suicide at least once during their lifetime and many attempts are successfully completed.
The annual average suicide rate is 0.4%, which is 10–20 times that of the general population. The standardized mortality ratio from suicide in bipolar disorder is between 18 and 25. The lifetime risk of suicide has been estimated to be as high as 20% in those with bipolar disorder.
Bipolar disorder is the sixth leading cause of disability worldwide and has a lifetime prevalence of about 3% in the general population. The incidence of bipolar disorder is similar in men and women as well as across different cultures and ethnic groups. Late adolescence and early adulthood are peak years for the onset of bipolar disorder.
In adults the course of bipolar disorder is characterized by discrete episodes of depression and mania with no clear symptomatology between them, in children and adolescents very fast mood changes or even chronic symptoms are the norm.
There is a relative lack of knowledge about bipolar disorder in late life.
There is evidence that it becomes less prevalent with age but nevertheless accounts for a similar percentage of psychiatric admissions; that older bipolar patients had first experienced symptoms at a later age; that later onset of mania is associated with more neurologic impairment; that substance abuse is considerably less common in older groups; and that there is probably a greater degree of variation in presentation and course, for instance individuals may develop new-onset mania associated with vascular changes, or become manic only after recurrent depressive episodes, or may have been diagnosed with bipolar disorder at an early age and still meet criteria.
There is also some weak and not conclusive evidence that mania is less intense and there is a higher prevalence of mixed episodes, although there may be a reduced response to treatment.
Overall, there are likely more similarities than differences from younger adults. In the elderly, recognition and treatment of bipolar disorder may be complicated by the presence of dementia or the side effects of medications being taken for other conditions.
