Mania Symptoms: The 7 DSM-5 Signs and How Often Each Appears

Mania symptoms are a cluster of changes in mood, energy, thinking and behavior: an abnormally elevated, expansive or irritable mood together with abnormally increased activity or energy, plus at least three of seven specific symptoms under DSM-5 criteria^[3]. Mania is the defining state of bipolar I disorder, one of the diagnoses within bipolar disorder, and a single manic episode is enough for that diagnosis^[1].

The seven DSM-5 symptoms are inflated self-esteem or grandiosity, decreased need for sleep, being more talkative than usual, racing thoughts or flight of ideas, distractibility, increased goal-directed activity or agitation, and risky activities with painful consequences^[3]. If the mood is only irritable rather than elevated, four of the seven are required^[3].

The symptoms must last at least one week, most of the day and nearly every day, or any length of time if hospitalization is needed^[3]. The American Psychiatric Association (APA) adds that the changes must be clear to friends and family and severe enough to disrupt work, family or social life^[1].

This article covers what each symptom looks like and how often it appears. How long episodes last, what triggers them and what recovery looks like are covered in manic episode.

Mood: euphoric, irritable or both

The mood change at the center of mania is not always happiness. NIMH describes feeling very up, high or elated, or extremely irritable or touchy^[2].

In a study of 316 inpatients with mania or mixed mania, irritability, dysphoric mood and rapid mood swings (mood lability) were prominent across the whole group, even though euphoria was present in a large portion^[4]. The authors concluded that mania is not a purely euphoric state^[4]. Episodes that combine manic and depressive symptoms at the same time are called mixed episodes^[2].

Grandiosity

Grandiosity means feeling unusually important, talented or powerful^[2]. In severe episodes it can become delusional: NIMH gives the example of someone who falsely believes they are famous or have special powers^[2].

The APA calls false beliefs, hallucinations and disorganized thinking during severe mania psychotic features^[1]. NIMH notes that people with bipolar disorder and psychotic symptoms can be misdiagnosed with schizophrenia^[2]. More detail is in psychosis symptoms.

Sleep

The DSM-5 sleep symptom is a decreased need for sleep, not insomnia: the person feels rested after as little as three hours^[3]. The APA describes it as feeling energetic despite significantly less sleep than usual^[1].

Speech and thinking

Speech becomes more abundant than usual, sometimes with a pressure to keep talking^[3]. Thoughts race or jump from topic to topic, which clinicians call flight of ideas, and attention is easily drawn to unimportant or irrelevant things^[3].

Activity and risk-taking

Activity rises socially, at work or school, or sexually, or shows up as purposeless restlessness called psychomotor agitation^[3]. NIMH also lists an excessive appetite for food, drinking, sex or other pleasurable activities, and feeling able to do many things at once without getting tired^[2].

Risk-taking is the symptom with the most visible consequences. DSM-5 examples include unrestrained buying sprees, sexual indiscretions and foolish business investments^[3], and the APA adds reckless driving^[1].

What mania feels like from the inside

In milder hypomanic states, people may feel very good and productive and not feel that anything is wrong, while family and friends notice the change in mood and activity^[2]. The APA's description requires that the changes be clear to friends and family, not only to the person^[1].

In a 1998 Duke University study of 316 inpatients with bipolar disorder, manic or mixed, the most frequently noted signs were motor activation, accelerated thinking, pressured speech and decreased sleep^[4]. The team rated 20 signs and symptoms in each patient^[4].

Grandiosity, euphoric mood and pressured speech were significantly more common in pure mania than in mixed episodes^[4]. Dysphoric mood, mood lability, anxiety, guilt, suicidality and irritability were more common in mixed episodes, while paranoia did not differ between the two groups^[4].

Suicidality was present in 7% of the whole cohort, including some patients who did not meet criteria for mixed mania^[4].

The core picture has been stable for more than a century. A 2017 review of 18 psychiatric textbooks published between 1899 and 1956 found that every author described elevated mood, grandiosity, hyperactivity, pressured speech, irritability and new activities with painful consequences^[5].

The same review found 22 prominent symptoms and signs reported by five or more authors, and DSM-5 contains only eight of the historically noted features^[5]. Impulsivity, hypersexuality, mood lability, altered moral standards, increased humor, hypergraphia and a vigorous physical appearance appear in none of the six modern criteria sets reviewed^[5].

NIMH says bipolar symptoms usually start in late adolescence or early adulthood, and that children occasionally experience them^[2]. The APA puts the average age of onset in the mid-20s^[1].

In youth, irritability is nearly as common as increased energy. A 2016 meta-analysis of 20 studies covering 2,226 youths found increased energy in 79%, irritability in 77% and mood lability in 76%^[6]. Decreased need for sleep (56%) and flight of ideas (54%) were among the less frequent symptoms on the list^[6].

Symptom rates varied widely between samples, and the authors found no clear pattern explaining the differences^[6]. They noted that the definition of pediatric bipolar disorder is still debated^[6].

Yes. Manic symptoms can be produced by medications, drugs and medical illness, which is why DSM-5 excludes episodes attributable to the physiological effects of a substance, a medication or other treatment^[3]. NIMH notes that thyroid disease can cause symptoms like those of bipolar disorder and that prescribed, recreational or illicit drugs can mimic or worsen mood symptoms^[2].

A 1978 review by Krauthammer and Klerman named this pattern secondary mania, after finding cases linked to drugs, infection, tumors, epilepsy and metabolic disturbances in people with no history of mood disorder^[8]. They argued that mania, like hypertension, is a syndrome with multiple causes^[8].

Corticosteroids

Steroid medications are a well-documented example. A 2006 Mayo Clinic Proceedings review reported that, across two large meta-analyses, severe psychiatric reactions occurred in nearly 6% of patients on systemic corticosteroids and mild to moderate reactions in about 28%^[10].

Euphoria and hypomania were the most common effects of short-term courses, while long-term therapy tended to produce depressive symptoms^[10]. Higher doses were associated with more reactions, and symptoms typically resolved when the dose was reduced or stopped^[10].

Antidepressants

NIMH states that antidepressants are not used alone in bipolar disorder because they can trigger a manic episode or rapid cycling^[2]. Under DSM-5, a full manic episode that begins during antidepressant treatment but persists beyond the drug's physiological effect counts as a manic episode^[3].

Mania that starts late in life

Mania that begins in older age is more often tied to neurological illness. A 1997 review linked mania in old age with late onset, a range of neurological disorders and poorer outcomes, with lesions often in the right hemisphere and the orbitofrontal and basotemporal cortex^[9]. Its evidence base was mostly small case series^[9].

Mania without depression

Some people with bipolar I disorder have manic episodes but never a major depressive episode, a pattern called unipolar mania. A 2026 meta-analysis of 26 studies and 17,716 people with bipolar I disorder put its pooled prevalence at 21.1%^[11]. The APA describes bipolar I disorder as diagnosed by a manic episode, with depressive or hypomanic episodes occurring in some people^[1].

Hypomania involves the same kinds of symptoms at lower intensity. The APA defines it as less severe manic symptoms lasting at least four days in a row, without the major problems in daily functioning that mania commonly causes^[1].

The dividing line is severity. Under DSM-5, an episode counts as manic when it causes marked impairment in social or occupational functioning, requires hospitalization to prevent harm to self or others, or includes psychotic features^[3].

A pattern of hypomanic and depressive episodes defines bipolar II disorder^[2]. How those symptoms differ from bipolar I is covered in bipolar 2 symptoms.

NIMH says a health care provider may complete a physical exam and order medical testing to rule out other illnesses before referring the person for a mental health evaluation^[2]. Diagnosis rests on the severity, length and frequency of symptoms over the person's lifetime, along with family history^[2].

One established severity measure is the Young Mania Rating Scale (YMRS), an 11-item clinician-administered scale introduced in 1978^[7]. In its validation study, two independent clinicians' total scores correlated at 0.93, and individual item scores at 0.66 to 0.92^[7].

YMRS scores also tracked how many days patients went on to stay in hospital, and they separated patients before and after two weeks of treatment^[7].

Self-report screening questionnaires and their accuracy are covered in bipolar test, and the full diagnostic process in how bipolar disorder is diagnosed.
