Hypomania

Hypomania

Hypomania (literally, below mania) is a mood state characterized by persistent and pervasive elevated or irritable mood, as well as thoughts and behaviors that are consistent with such a mood state. Individuals in a hypomanic state have a decreased need for sleep, are extremely outgoing and competitive, and have a great deal of energy. However, unlike with full mania, those with hypomanic systems are fully functioning, and are often actually more productive than usual. Specifically, hypomania is distinguished from mania by the absence of psychotic symptoms and by its lower degree of impact on functioning. Hypomania is a feature of bipolar II disorder and cyclothymia, but can also occur in schizoaffective disorder. Hypomania is sometimes credited with increasing creativity and productive energy. A significant number of people with creative talents have reportedly experienced hypomania or other symptoms of bipolar disorder and attribute their success to it. Classic symptoms of hypomania include mild euphoria, a flood of ideas, endless energy, and a desire and drive for success. A lesser form of hypomania is called hyperthymia.

Hypomania is also a side effect of numerous medications, often—though not always—those used in psychopharmacotherapy. Patients suffering from severe depression who experience hypomania as a side effect of (for example) antidepressants, may prove to have a form of bipolar disorder that has previously gone unrecognized. However, drug-induced hypomania is not invariably indicative of bipolar affective disorders. The difference between uni- and bi-polar disorders is essential for analysis of switches. Consequently, it is important for researchers and mental health professionals to distinguish drug-induced hypomania in bipolar patients from drug-induced hypomania in unipolar (non-bipolar) depressives. Nevertheless if antidepressants trigger the first episode of hypomania, it is strongly suggestive of an underlying diagnosis of Bipolar Disorder, particularly if the manic symptoms (mild, moderate or severe) last for a lengthy period of time after they start. In cases of true drug-induced hypomania, cessation of the antidepressant or whichever drug has triggered this mood state – for example steroid therapy or stimulants such as amphetamine – usually causes a fairly swift return to normal mood. It is far less likely to be a side effect in those with pure Clinical Unipolar Depression, unless for example tricyclic antidepressants are given in very high doses. SSRIs are less likely to trigger manic symptoms except in those individuals where there is an underlying Bipolar Disorder, particularly if administered without a mood stabilizer.

Often in those who have experienced their first episode of hypomania (which is a level of mild to moderate mania) – generally without psychotic features – there will have been a long or recent history of depression prior to the emergence of manic symptoms, and commonly this surfaces in the mid to late teens. Due to this being an emotionally charged time, it is not unusual for mood swings to be passed off as hormonal or teenage ups and downs and for a diagnosis of Bipolar Disorder to be missed until there is evidence of an obvious manic/hypomanic phase.

Hypomania may also occur as a side effect of pharmaceuticals prescribed for conditions/diseases other than psychological states or mood disorders. In those instances, as in cases of drug-induced hypomanic episodes in unipolar depressives, the hypomania can almost invariably be eliminated by lowering medication dosage, withdrawing the drug entirely, or changing to a different medication if discontinuation of treatment is not possible.

Symptomatic recognition
The DSM-IV-TR defines a hypomanic episode as including, over the course of at least four days, elevated mood plus three of the following symptoms OR irritable mood plus four of the following symptoms:

* pressured speech; rapid talking but research[which?] shows this feature is not found in 25% of individuals with other manic symptoms.
* inflated self-esteem or grandiosity;
* decreased need for sleep;
* flight of ideas or the subjective experience that thoughts are racing;
* easy distractibility and attention-deficit (superficially[citation needed] similar to attention deficit hyperactivity disorder);
* increase in psychomotor agitation; and
* involvement in pleasurable activities that may have a high potential for negative psycho-social or physical consequences (e.g., the person engages in unrestrained buying sprees, sexual indiscretions, reckless driving, or foolish business investments).

Explanation of common symptoms
* In the hypomanic state, people may feel that they cannot slow their minds down, and that their speeding thoughts are crafted exceptionally well. Some examples are speaking or writing in rhyme or alliteration without planning it first; quick responses to people talking; or the ability to improvise easily.
* People in hypomanic episodes do not have delusions or hallucinations. They do not lose touch with reality in the sense that they know who they are and what is real. What can be a problem, however, is that people in a hypomanic state can sometimes

* Overestimate their capabilities and fail to see the risks involved in their ventures. For example, a person may suddenly decide to expand a business in a way that is not really practical or set up schemes for which he or she is ill-prepared, or pursue an unrealistic love interest.
* Hypomanic individuals may also experience difficulty with decision making, resulting in behavior such as reckless driving, gambling, spending sprees and sexual adventures. To a varying degree, promiscuity, loss of social inhibitions, and risk taking, are all very common in hypomanic episodes. Many have described hypomanic individuals as ‘the life of the party’.

It is unknown to what degree hypomanic symptoms can occur without a depressive component. Patients may be relatively unlikely to seek psychiatric treatment for hypomania alone. However, many hypomanic patients also experience:

* obsessive behavior, whether mild or severe
* excessive risk-taking (e.g., gambling, foolish business decisions)
* general poor judgment
* a decreased need for sleep. Many hypomanic individuals may get at little as 3–6 hours of sleep a night
* uncontrolled, or only partially controllable, impulsivity
* excessive sexual activity or sexual risk taking

Plus other out-of-character behaviors that the person may regret following the conclusion of the mood episode. A more mild form of elevated mood, which has fewer negative behaviors, is hyperthymic temperament.

Hypomania can signal the beginning of a more severe manic episode, and often does result in a more severe manic episode if the hypomanic episode remains untreated. A hypomanic episode can also directly precede a depressive episode.

Possible benefits
Some commentators believe that hypomania actually has an evolutionary advantage. People with hypomania are generally perceived as being energetic, euphoric, visionary, overflowing with new ideas, and sometimes over-confident and very charismatic, yet—unlike those with full-blown mania—are sufficiently capable of coherent thought and action to participate in everyday activities. Like mania, there seems to be a significant correlation between hypomania and creativity. A person in the state of hypomania might be immune to fear and doubt and have little social and sexual inhibition. People experiencing hypomania are often the “life of the party.” They may talk to strangers easily, offer solutions to problems, and find pleasure in small activities. Such advantages may render them unwilling to submit to treatment, especially when disadvantages are minimal.

Relationship with disorders
Cyclothymia is a condition of continued mood fluctuations between hypomania and depressive symptoms that do not meet the criteria for a Major Depressive Episode. These are often interspersed with periods of normal moods.

When a patient presents with a history of one or more hypomanic episodes and one or more depressive episodes that meet the criteria for a Major Depressive Episode, Bipolar II Disorder is diagnosed. If left untreated, hypomania can transition into mania and sometimes psychosis, in which case, Bipolar I Disorder is often diagnosed.

Treatment
Clinical trials of medications for the non-depressive phases of bipolar illnesses generally treat patients for psychotic mania during the initial, or acute, phase of mania. High doses are justified in the case of mania, in order to remove the patient from immediate danger. Hypomania, however, involves different considerations and almost always requires more in-depth clinical judgment. Medications typically prescribed for hypomania include mood stabilizers such as valproic acid and lithium carbonate as well as atypical antipsychotics such as olanzapine and quetiapine.
