The tendency for BP-II to be misdiagnosed and treated ineffectively, or not at all in some cases, leads to an increased risk.As a result of the high suicide risk for this group, reducing the risk and preventing attempts remains a main part of the treatment; a combination of self-monitoring, close supervision by a therapist, and faithful adherence to their medication regimen will help to reduce the risk and prevent the likelihood of suicide.Suicide is a common endpoint for many patients with severe psychiatric illness. The mood disorders (depression and bipolar) are by far the most common psychiatric conditions associated with suicide. At least 25% to 50% of patients with bipolar disorder also attempt suicide at least once. Aside from lithium—which is the most demonstrably effective treatment against suicide—little is known about contributions of specific mood-altering treatments to minimizing mortality rates in persons with either major mood disorders or bipolar depression specifically. Suicide is usually a manifestation of severe psychiatric distress that is often associated with a diagnosable and treatable form of depression or other mental illness. In a clinical setting, an assessment of suicidal risk must precede any attempt to treat psychiatric illness. Epidemiology
The global estimated lifetime prevalence of bipolar disorder among adults range from 1 to 3 percent. The annual incidence is estimated to vary from 0.3 to 1.2 percent worldwide. According to the World Mental Health Survey Initiative, the lifetime prevalence of BP-II was found to be 0.4%, with a 12-month prevalence of 0.3%.
Individuals often will only seek treatment during a depressive episode, and their history of hypomania may go undiagnosed. Although hypomania may increase functioning, episodes require treatment as they may indicate increasing instability and can precipitate a depressive episode. Depressive episodes
It is during depressive episodes that BP-II patients often seek help. Symptoms may be syndromal or subsyndromal.Depressive episodes in BP-II can present similarly to those experienced in unipolar depressive disorders. Patients characteristically experience a depressed mood and may describe themselves as feeling sad, gloomy, down in the dumps, hopeless, or for most of the day, nearly every day. In children, this can present with an irritable mood. Most patients report significant fatigue, loss of energy, or tiredness. Patients or their family members may note diminished interest in usual activities such as sex, hobbies, or daily routines. Many patients report a change in appetite along with associated weight change. Sleep disturbances may be present, and can manifest as problems falling or staying asleep, frequent awakenings, excessive sleep, or difficulties getting up in the morning. Around half of depressed patients develop changes in psychomotor activity, described as slowness in thinking, speaking, or movement. Conversely, they may also present with agitation, with inability to sit still or wringing their hands. Changes in posture, speech, facial expression, and grooming can be observed.
