Often religious beliefs intensify or people believe they are an important religious figure. Lack of insight - people experiencing mania may not recognise that their behaviour is inappropriate, although they may understand that other people see their ideas and actions as inappropriate, reckless, or irrational.
Mania is diagnosed when symptoms have been present for a week or more. Hypomania is less severe and may have shorter duration. Normal moods Most people who have episodes of mania and depression experience normal moods in between. They are able to live their lives productively and manage home and work commitments. It is when moods become extreme and interfere with a person's life that assessment and treatment for mental illness becomes necessary.

These subtypes—what the DSM-5 refer to as specifiers—are not specific disorders; rather, they are labels used to indicate specific patterns of symptoms or to specify certain periods of time in which the symptoms may be present.
One subtype, seasonal pattern , applies to situations in which a person experiences the symptoms of major depressive disorder only during a particular time of year e. In everyday language, people often refer to this subtype as the winter blues. Another subtype, peripartum onset commonly referred to as postpartum depression , applies to women who experience major depression during pregnancy or in the four weeks following the birth of their child APA, These women often feel very anxious and may even have panic attacks.
They may feel guilty, agitated, and be weepy. They may not want to hold or care for their newborn, even in cases in which the pregnancy was desired and intended. In extreme cases, the mother may have feelings of wanting to harm her child or herself. In a horrific illustration, a woman named Andrea Yates, who suffered from extreme peripartum-onset depression as well as other mental illnesses , drowned her five children in a bathtub Roche, Most women with peripartum-onset depression do not physically harm their children, but most do have difficulty being adequate caregivers Fields, A surprisingly high number of women experience symptoms of peripartum-onset depression.
People with persistent depressive disorder previously known as dysthymia experience depressed moods most of the day nearly every day for at least two years, as well as at least two of the other symptoms of major depressive disorder.
People with persistent depressive disorder are chronically sad and melancholy, but do not meet all the criteria for major depression. However, episodes of full-blown major depressive disorder can occur during persistent depressive disorder APA, To be diagnosed with bipolar disorder, a person must have experienced a manic episode at least once in his life; although major depressive episodes are common in bipolar disorder, they are not required for a diagnosis APA, During a manic episode, some experience a mood that is almost euphoric and become excessively talkative, sometimes spontaneously starting conversations with strangers; others become excessively irritable and complain or make hostile comments.
The person may talk loudly and rapidly, exhibiting flight of ideas , abruptly switching from one topic to another. These individuals are easily distracted, which can make a conversation very difficult. They may exhibit grandiosity, in which they experience inflated but unjustified self-esteem and self-confidence. They may take on several tasks at the same time e. Patients may also recklessly engage in pleasurable activities that could have harmful consequences, including spending sprees, reckless driving, making foolish investments, excessive gambling, or engaging in sexual encounters with strangers APA, During a manic episode, individuals usually feel as though they are not ill and do not need treatment.
However, the reckless behaviors that often accompany these episodes—which can be antisocial, illegal, or physically threatening to others—may require involuntary hospitalization APA, Some patients with bipolar disorder will experience a rapid-cycling subtype, which is characterized by at least four manic episodes or some combination of at least four manic and major depressive episodes within one year. In the Showtime Series Shameless, the character Ian has been diagnosed with bipolar disorder and cycles between manic and depressive periods seen here.
Bipolar disorder is considerably less frequent than major depressive disorder. In the United States, 1 out of every people meets the criteria for bipolar disorder each year, and 1 out of meet the criteria within their lifetime Merikangas et al. The rates are higher in men than in women, and about half of those with this disorder report onset before the age of 25 Merikangas et al.
Mood disorders have been shown to have a strong genetic and biological basis. Relatives of those with major depressive disorder have double the risk of developing major depressive disorder, whereas relatives of patients with bipolar disorder have over nine times the risk Merikangas et al.
People with mood disorders often have imbalances in certain neurotransmitters, particularly norepinephrine and serotonin Thase, These neurotransmitters are important regulators of the bodily functions that are disrupted in mood disorders, including appetite, sex drive, sleep, arousal, and mood. Medications that are used to treat major depressive disorder typically boost serotonin and norepinephrine activity, whereas lithium—used in the treatment of bipolar disorder—blocks norepinephrine activity at the synapses.
Many medications designed to treat mood disorders work by altering neurotransmitter activity in the neural synapse.
Because the PFC can dampen amygdala activation, thereby enabling one to suppress negative emotions Phan et al. These findings suggest that depressed persons are more prone to react to emotionally negative stimuli, yet have greater difficulty controlling these reactions.
Depressed individuals react to negative emotional stimuli, such as sad faces, with greater amygdala activation than do non-depressed individuals.
When cortisol is released, the body initiates a fight-or-flight response in reaction to a threat or danger. Such findings raise the question of whether high cortisol levels are a cause or a consequence of depression.
Thus, high cortisol levels may have a causal effect on depression, as well as on its brain function abnormalities van Praag, Also, because stress results in increased cortisol release Michaud, Matheson, Kelly, Anisman, , it is equally reasonable to assume that stress may precipitate depression.
Indeed, it has long been believed that stressful life events can trigger depression, and research has consistently supported this conclusion Mazure, In particular, exit events—instances in which an important person departs e.
Exit events are especially likely to trigger depression if these happenings occur in a way that humiliates or devalues the individual. Likewise, individuals who are exposed to traumatic stress during childhood—such as separation from a parent, family turmoil, and maltreatment physical or sexual abuse —are at a heightened risk of developing depression at any point in their lives Kessler, Of course, not everyone who experiences stressful life events or childhood adversities succumbs to depression—indeed, most do not.
If so, what might such predispositions be? Bipolar disorder generally occurs before the age of 30 years and may first develop during adolescence. Not only adults become depressed.
Children and teenagers also may have depression, as well. The good news is that depression is a treatable illness. About 5 percent of children and adolescents in the general population suffer from depression at any given point in time.
