00:00Bipolar 1 disorder is defined by the presence of at least one full manic episode.
00:07A manic episode is a period of abnormally elevated, expansive, or irritable mood
00:13that lasts at least one week or any duration if hospitalization is required.
00:20During mania, energy is markedly increased, and people often show inflated self-esteem or grandiosity,
00:27decreased need for sleep, pressured or rapid speech, racing thoughts, and impulsive high-risk behavior
00:34such as reckless spending, substance use, or dangerous driving.
00:40Functioning is clearly impaired.
00:42Work, relationships, and daily responsibilities often fall apart,
00:46or the person may require hospital care to prevent harm.
00:50Depressive episodes are common but not required for the diagnosis.
00:54Major depression in Bipolar 1 involves at least two weeks of low mood or loss of interest,
01:00combined with changes in sleep, appetite, energy, concentration, or thoughts of death.
01:07The pattern over time varies.
01:10Some people have long, stable periods between episodes, while others cycle more often.
01:15Diagnosis requires ruling out mood symptoms caused by substances or medical conditions,
01:21and confirming that the mood shifts are not better explained by another psychiatric disorder.
01:28Bipolar 2 disorder is characterized by a pattern of at least one hypomanic episode
01:33and at least one major depressive episode without any history of a full manic episode.
01:40Hypomania involves elevated or irritable mood and increased energy,
01:45but the intensity is less severe than mania and does not cause the same level of social or occupational collapse.
01:53Symptoms can include reduced need for sleep, increased talkativeness, racing thoughts, and goal-directed activity,
02:00but the person can often continue working or interacting with others.
02:05Because hypomania may feel productive or positive, it is frequently overlooked or not reported.
02:12The depressive episodes in Bipolar 2 are often severe and long-lasting,
02:18leading to significant impairment, suicidal thoughts, and functional decline.
02:24Many people with Bipolar 2 seek help only for depression
02:27and are misdiagnosed with unipolar major depression.
02:31Correct identification of past hypomanic periods is critical
02:35because it changes treatment planning and informs the expected course of illness over time.
02:40Cyclothymic disorder is a chronic pattern of fluctuating mood
02:45that never fully meets the criteria for a full hypomanic or major depressive episode,
02:50but still causes distress and functional problems.
02:54For adults, symptoms must be present for at least two years,
02:58with numerous periods of hypomanic symptoms
03:00and periods of depressive symptoms that do not reach full episode intensity.
03:05People with cyclothymia often describe themselves as emotionally unstable,
03:11reactive, or up and down, without clear triggers.
03:16The highs may include increased energy, talkativeness, or reduced sleep,
03:21while the lows bring fatigue, pessimism, and social withdrawal.
03:26There are typically no long stretches of stable mood.
03:29Symptoms occur for at least half the time,
03:32with no symptom-free period longer than about two months.
03:36Cyclothymia is considered part of the bipolar spectrum
03:39because the pattern suggests an underlying instability in mood regulation.
03:45It carries a risk of eventually developing full bipolar I or ITI disorder,
03:49especially under stress or with substance use.
03:53Rapid cycling is a course specifier applied when a person with bipolar disorder
03:57experiences four or more distinct mood episodes within a 12-month period.
04:02These episodes can be manic, hypomanic, or depressive,
04:05and they must meet full duration and symptom criteria.
04:09Rapid cycling is not a separate diagnosis.
04:12Rather, it describes how often mood states change.
04:17This pattern is associated with greater functional impairment,
04:20more severe symptoms, and a more difficult treatment course.
04:23Some individuals experience periods of rapid cycling for a few years
04:28and then return to a slower episode pattern,
04:31while others have persistent rapid cycling.
04:34Factors that may contribute include thyroid abnormalities,
04:38antidepressant use in some cases,
04:41and certain biological vulnerabilities.
04:44Clinically, rapid cycling requires careful tracking of mood shifts over time,
04:49often with mood charts or apps,
04:51because the frequent transitions can be confusing
04:54and may lead to misinterpretation of symptoms
04:57as personality problems rather than episodic illness.
05:02Mixed features describe episodes in which symptoms of mania and depression
05:07occur simultaneously or in very close succession.
05:11For example, a person may feel extremely agitated,
05:15restless, and talkative while also experiencing hopelessness,
05:19guilt, and suicidal thoughts.
05:21In bipolar I, mixed features most often appear during manic episodes.
05:27In bipolar II, they may occur during hypomanic or depressive episodes.
05:32Mixed states are clinically important
05:35because they are associated with higher risk of self-harm,
05:38greater distress, and poorer response to some medications.
05:43Patients may appear irritable and volatile rather than euphoric or slowed,
05:47which can lead to mislabeling as personality or behavioral problems.
05:52The diagnostic specifier with mixed features is added when a threshold number of opposite polarity
05:59symptoms is present during a mood episode.
06:03Treatment planning must account for both sets of symptoms at once,
06:07focusing on stabilizing mood rather than treating only depression or only mania.
06:12Psychotic features occur when hallucinations or delusions appear during manic,
06:18hypomanic, or depressive episodes.
06:21Hallucinations involve perceiving things that are not actually present,
06:25such as hearing voices or seeing figures.
06:29Delusions are fixed,
06:30false beliefs that do not change even when clear evidence is presented,
06:35such as believing one has a special mission from a higher power,
06:38or that others are plotting harm.
06:40In bipolar disorder, psychotic content is usually mood-congruent.
06:46During mania, delusions may involve grandiosity, special powers, or unlimited wealth.
06:53During depression, psychotic ideas may involve guilt, worthlessness,
06:58or the belief that one's body is diseased or rotting.
07:03Psychotic features significantly raise the level of impairment
07:07and often require hospitalization.
07:10Diagnosis distinguishes bipolar disorder with psychotic features
07:14from primary psychotic illnesses like schizophrenia
07:17by showing that psychosis only occurs during clear mood episodes
07:22and resolves when mood stabilizes.
07:26The anxious distress specifier is used when a person with bipolar disorder
07:30experiences prominent anxiety symptoms during mood episodes.
07:34These can include excessive worry, feeling keyed up or tense,
07:38difficulty concentrating because of fear,
07:41and a sense that something terrible is about to happen.
07:44Anxious distress can appear during manic, hypomanic, or depressive states
07:49and is associated with greater subjective suffering,
07:52higher suicide risk, and a more complicated treatment course.
07:56People with bipolar disorder and anxious distress may be more likely to misuse substances
08:02or avoid situations that trigger anxiety,
08:05which can worsen social and occupational functioning.
08:09The specifier is applied when a minimum number of anxiety symptoms
08:14are present most days of the episode.
08:16Clinically, recognizing anxious distress matters because it guides the choice
08:22and sequence of medications and psychotherapies,
08:25as some anxiety-targeting treatments can destabilize mood
08:29if used without careful monitoring.
08:33A seasonal pattern is diagnosed when mood episodes and bipolar disorder occur
08:38at characteristic times of the year for at least two consecutive years,
08:42without non-seasonal episodes in that period.
08:46A common example is depressive episodes emerging in late fall or winter
08:50when daylight decreases,
08:52and hypomanic or manic episodes emerging in spring or early summer.
08:58The pattern is thought to involve changes in circadian rhythms,
09:02melatonin secretion,
09:03and light exposure that influence brain systems regulating mood.
09:08People with a seasonal pattern often report predictable changes
09:12in sleep, appetite, energy, and motivation as the seasons change.
09:18Recognizing a seasonal pattern allows clinicians to prepare preventive strategies,
09:23such as adjusting medications before the usual onset period
09:26and using evidence-based light therapy for certain depressive presentations.
09:32It also helps differentiate bipolar disorder from recurrent major depression
09:37with seasonal pattern, which does not include manic or hypomanic episodes.
09:43Peripartum onset refers to mood episodes that begin during pregnancy
09:47or within several weeks after childbirth in individuals with bipolar disorder.
09:53This period involves major hormonal shifts, sleep disruption, and psychosocial stress,
09:58all of which can trigger mood instability in biologically vulnerable individuals.
10:04Peripartum bipolar episodes can be depressive, hypomanic, manic, or mixed,
10:10and they often appear abruptly.
10:12Severe manic or mixed episodes after delivery, especially with psychotic features,
10:17are considered psychiatric emergencies due to high risk of harm to self or the infant.
10:24Distinguishing bipolar
10:25Peripartum episodes from unipolar postpartum depression is critical
10:29because treatment strategies differ,
10:32and some medications carry specific risks for pregnancy and breastfeeding.
10:37Early identification, close monitoring, and coordinated care
10:41between psychiatry and obstetrics are central to managing this specifier safely.
10:46Catatonia is a syndrome of marked disturbances in movement and behavior
10:52that can occur during mood episodes in bipolar disorder.
10:57Symptoms may include stupor, no psychomotor activity and minimal response to the environment,
11:03mutism, waxy flexibility, maintaining positions after being placed,
11:08odd posturing, negativism, resistance to instructions, or excessive, purposeless agitation.
11:16Catatonia is not a separate diagnosis in this context,
11:20but a specifier that signals severe illness requiring urgent treatment.
11:25It can appear during manic, depressive, or mixed episodes.
11:29Because catatonia can resemble neurological or medical conditions,
11:33careful evaluation is needed to rule out other causes.
11:38Standard treatments, such as certain medications or specific medical procedures,
11:42often produce rapid improvement when catatonia is correctly identified.
11:48Failure to recognize catatonia can lead to complications like dehydration,
11:53malnutrition, or muscle breakdown due to prolonged immobility or agitation.
11:59Atypical features describe a specific pattern of depressive symptoms in bipolar disorder.
12:05Instead of the classic picture of low appetite, early morning awakening, and slowed movement,
12:10atypical depression involves mood reactivity, increased appetite or weight gain,
12:16excessive sleep, and a heavy, leaden feeling in the arms or legs.
12:20People may be extremely sensitive to rejection, experiencing intense emotional pain
12:25in response to perceived criticism or abandonment.
12:29These features can occur within bipolar I or bipolar II depression
12:33and may overlap with anxiety or personality vulnerabilities.
12:39The term atypical does not mean rare.
12:42It simply means that the symptom pattern differs from the traditional melancholic profile.
12:48Recognizing atypical features helps guide medication choice and predicts certain course patterns,
12:54such as earlier onset and higher risk of co-occurring conditions,
12:59including anxiety disorders and substance use.
13:02Drug-Induced Bipolar Disorder
13:06This diagnosis applies when manic, hypomanic, or mixed symptoms
13:11are directly caused by substances, medications, or toxins,
13:16rather than by a primary bipolar illness.
13:19Common triggers include stimulant drugs, certain antidepressants,
13:23corticosteroids, and some substances of abuse.
13:26The key features are that mood symptoms begin during or soon after substance exposure,
13:32exceed what would be expected from simple intoxication or withdrawal,
13:36and resolve or greatly improve after the substance is discontinued.
13:41Careful history-taking is necessary to distinguish this condition from primary bipolar disorder
13:46that is merely triggered or worsened by substances.
13:49In substance-induced cases, long-term treatment focuses
13:53on managing the underlying medical or substance use problems and avoiding re-exposure.
14:00In primary bipolar disorder, substance use may still be present,
14:04but the mood pattern persists independently of any specific drug or medication.
14:10Medically-caused Bipolar Disorder
14:13This diagnosis is used when a medical illness directly disrupts brain function
14:18and produces manic, hypomanic, or mixed mood symptoms.
14:23Examples include certain neurological conditions,
14:27such as stroke, multiple sclerosis, or traumatic brain injury.
14:31Endocrine disorders, like hyperthyroidism,
14:34and other systemic illnesses that affect the central nervous system.
14:38The temporal relationship is crucial.
14:42Mood changes appear after the onset of the medical condition
14:45and cannot be better explained by a primary psychiatric disorder or substance use.
14:51Laboratory tests, imaging, and specialist evaluations
14:55often play a central role in confirming the underlying cause.
15:00Treating the medical condition may significantly reduce or eliminate the mood symptoms,
15:05though in some cases ongoing psychiatric treatment is still necessary.
15:10This diagnosis highlights that not all bipolar-like presentations
15:14represent classic bipolar disorder.
15:18Some are secondary to identifiable physical disease.
15:22Ultra-rapid cycling describes a pattern in which mood episodes in bipolar disorder
15:28shift over days rather than weeks or months.
15:31A person may experience several distinct manic, hypomanic, or depressive states in a single month,
15:38each lasting a few days but still reaching threshold for a full episode.
15:44This concept is mainly used in clinical research and practice
15:48to capture very unstable mood courses that go beyond standard rapid cycling.
15:53Individuals with ultra-rapid cycling often report feeling as though their emotional state
15:59is constantly shifting beyond their control,
16:02making work, relationships, and long-term planning especially difficult.
16:08Accurate tracking with daily mood logs is essential
16:11because retrospective recall of so many changes can be unreliable.
16:16This pattern is associated with higher illness burden
16:20and treatment may require more complex combinations of mood stabilizers
16:24and lifestyle interventions aimed at stabilizing sleep, routines, and stress exposure.
16:32Ultra-d in cycling refers to mood shifts that occur multiple times within a single day.
16:38Instead of having separate episodes lasting days or weeks,
16:41a person may move from elevated to depressed to irritable states over hours.
16:46This pattern is controversial as current diagnostic manuals
16:50are structured around episodes lasting at least several days,
16:54but the term is used clinically to describe extreme mood lability
16:58in some individuals with bipolar disorder.
17:02Ultradion cycling can be mistaken for personality disorders,
17:06attention deficit, hyperactivity disorder,
17:09or trauma-related instability because external behavior may look similar.
17:15However, in bipolar ultradion cycling,
17:18the shifts still reflect underlying changes in mood, energy, and thinking patterns
17:23consistent with the bipolar spectrum.
17:27Assessment focuses on repeated real-time mood monitoring,
17:30collateral information from family or partners,
17:33and careful differentiation from reactions to external events.
17:37Management is challenging and typically involves comprehensive treatment plans
17:42addressing sleep, medications, and environmental structure.
17:46Some individuals experience recurrent manic episodes without clear major depressive episodes.
17:52In these cases, the diagnosis falls under bipolar eye disorder,
17:57but the clinical course is described as mania-predominant or manic-only.
18:02During mania, people may show euphoric or irritable mood,
18:05severely reduced sleep, increased goal-directed activity,
18:10excessive spending, sexual risk-taking, or aggressive behavior.
18:15The absence of documented depression does not lessen the seriousness of the condition.
18:20Manic episodes alone can cause legal, financial, and interpersonal damage.
18:26Over a lifetime, many people who initially seem to have only manic episodes
18:31eventually experience depression as well, but a subgroup remains predominantly manic.
18:37Recognizing this pattern helps avoid inappropriate assumptions about depressive risk,
18:42while still planning long-term mood-stabilizing strategies and safety measures around future manic relapses.
18:49In depression-dominant bipolar disorder,
18:52major depressive episodes are frequent, long-lasting, or severe,
18:56while manic or hypomanic episodes are relatively rare, brief, or mild.
19:03Many individuals with this pattern are initially misdiagnosed with recurrent unipolar major depression
19:08because their elevated phases are subtle or retrospectively underreported.
19:14Hypomania may appear only after antidepressant treatment
19:17or during periods of reduced sleep and high stress.
19:20The key diagnostic point is that at least one episode of mania or hypomania
19:26has occurred at some point, distinguishing this condition from pure depression.
19:32Depression-dominant bipolar illness tends to be associated with significant functional impairment,
19:38high suicide risk, and frequent health care use.
19:42Identifying the underlying bipolarity leads to different medication choices and cautions
19:48around antidepressant use, emphasizing mood stabilizers and psychoeducation
19:54about early warning signs of mood elevation.
19:57Mania-dominant bipolar disorder is characterized by repeated manic or hypomanic episodes
20:03with relatively few or brief depressive episodes.
20:07Individuals may seek help primarily during crises involving agitation, aggression, or risky behavior,
20:14often brought in by family or law enforcement.
20:17Between episodes, they may feel well or even believe treatment is unnecessary,
20:22which can contribute to medication, non-adherence, and high relapse rates.
20:28Mania-dominant patterns are linked to significant disruption in employment, finances, and relationships
20:34due to repeated impulsive actions taken during elevated states.
20:40Clinicians focus on documenting the frequency, duration, and severity of manic episodes over time.
20:47As well as any sub-threshold depressive symptoms that may still be clinically relevant.
20:54Long-term management centers on mood stabilizers, structured routines,
20:59and close follow-up to catch early signs of future manic escalation.
21:04In mixed-dominant bipolar disorder, mixed episodes are the primary or most disabling mood state over time.
21:12Instead of distinct, cleanly separated periods of mania and depression,
21:17individuals frequently experience overlapping symptoms.
21:21Agitation and racing thoughts combined with despair,
21:25high energy combined with suicidal ideation,
21:28or irritability combined with severe anxiety.
21:31This presentation is often misinterpreted as purely anxiety-related, trauma-related,
21:38or personality-based because the person may not appear classically euphoric or slowed.
21:44Mixed-dominant patterns are strongly associated with increased self-harm risk
21:49and intense subjective distress, making early recognition crucial.
21:53Diagnosis is based on repeated documentation that episodes regularly include both manic,
22:00hypomanic, and depressive features meeting threshold criteria.
22:04Treatment typically prioritizes mood-stabilizing and antipsychotic medications
22:09that target both poles simultaneously while carefully evaluating the risks of standard antidepressants,
22:17which can worsen mixed states in some individuals.
