Bipolar disorder, previously known as manic depression, is a mental disorder characterized by periods of depression and periods of abnormally elevated mood that each last from days to weeks. If the elevated mood is severe or associated with psychosis, it is called mania; if it is less severe and does not significantly affect functioning, it is called hypomania. During mania, an individual behaves or feels abnormally energetic, happy or irritable, and they often make impulsive decisions with little regard for the consequences. There is usually also a reduced need for sleep during manic phases. During periods of depression, the individual may experience crying and have a negative outlook on life and poor eye contact with others. The risk of suicide is high; over a period of 20 years, 6% of those with bipolar disorder died by suicide, while 30–40% engaged in self-harm. Other mental health issues, such as anxiety disorders and substance use disorders, are commonly associated with bipolar disorder.
Catatonia is a complex neuropsychiatric behavioral syndrome that is characterized by abnormal movements, immobility, abnormal behaviors, and withdrawal. The onset of catatonia can be acute or subtle and symptoms can wax, wane, or change during episodes. It has historically been related to schizophrenia, but catatonia is most often seen in mood disorders. It is now known that catatonic symptoms are nonspecific and may be observed in other mental, neurological, and medical conditions. Catatonia is now a stand-alone diagnosis, and the term is used to describe a feature of the underlying disorder.
Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive low mood, low self-esteem, and loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this symptom cluster under mood disorders in the 1980 version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), and has become widely used since. The disorder causes the second-most years lived with disability, after lower back pain.
Electroconvulsive therapy (ECT) or electroshock therapy (EST) is a psychiatric treatment where a generalized seizure is electrically induced to manage refractory mental disorders. Typically, 70 to 120 volts are applied externally to the patient's head, resulting in approximately 800 milliamperes of direct current passing between the electrodes, for a duration of 100 milliseconds to 6 seconds, either from temple to temple or from front to back of one side of the head. However, only about 1% of the electrical current crosses the bony skull into the brain because skull impedance is about 100 times higher than skin impedance.
Links between creativity and mental health have been extensively discussed and studied by psychologists and other researchers for centuries. Parallels can be drawn to connect creativity to major mental disorders including bipolar disorder, autism, schizophrenia, major depressive disorder, anxiety disorder, OCD and ADHD. For example, studies have demonstrated correlations between creative occupations and people living with mental illness. There are cases that support the idea that mental illness can aid in creativity, but it is also generally agreed that mental illness does not have to be present for creativity to exist.
State-dependent memory or state-dependent learning is the phenomenon where people remember more information if their physical or mental state is the same at time of encoding and time of recall. State-dependent memory is heavily researched in regards to its employment both in regards to synthetic states of consciousness as well as organic states of consciousness such as mood. While state-dependent memory may seem rather similar to context-dependent memory, context-dependent memory involves an individual's external environment and conditions while state-dependent memory applies to the individual's internal conditions.
Lauretta Bender was an American child neuropsychiatrist known for developing the Bender-Gestalt Test, a psychological test designed to evaluate visual-motor maturation in children. First published by Bender in 1938, the test became widely used for assessing children's neurological function and screening for developmental disorders.
Bipolar disorder in children, or pediatric bipolar disorder (PBD), is a rare mental disorder in children and adolescents. The diagnosis of bipolar disorder in children has been heavily debated for many reasons including the potential harmful effects of adult bipolar medication use for children. PBD is similar to bipolar disorder (BD) in adults, and has been proposed as an explanation for periods of extreme shifts in mood called mood episodes. These shifts alternate between periods of depressed or irritable moods and periods of abnormally elevated moods called manic or hypomanic episodes. Mixed mood episodes can occur when a child or adolescent with PBD experiences depressive and manic symptoms simultaneously. Mood episodes of children and adolescents with PBD are different from general shifts in mood experienced by children and adolescents because mood episodes last for long periods of time and cause severe disruptions to an individual's life. There are three known forms of PBD: Bipolar I, Bipolar II, and Bipolar Not Otherwise Specified (NOS). The average age of onset of PBD remains unclear, but reported age of onset ranges from 5 years of age to 19 years of age. PBD is typically more severe and has a poorer prognosis than bipolar disorder with onset in late-adolescence or adulthood.
LifeLock Inc. was an American software company active from 2005 to 2017. The company was best known for its eponymous LifeLock identity theft prevention software, now sold by Gen Digital after the latter acquired LifeLock in 2017. LifeLock's system monitors for identity theft, the use of personal information, and credit score changes.
Bipolar II disorder (BP-II) is a mood disorder on the bipolar spectrum, characterized by at least one episode of hypomania and at least one episode of major depression. Diagnosis for BP-II requires that the individual must never have experienced a full manic episode. Otherwise, one manic episode meets the criteria for bipolar I disorder (BP-I).
Richard Todd Davis, also known as Todd Davis, is the cofounder of LifeLock, an American identity theft protection company based in Tempe, Arizona, that became a subsidiary of Symantec in 2019.
Joseph Biederman was an American academic psychiatrist. He was Chief of the Clinical and Research Programs in Pediatric Psychopharmacology and Adult ADHD at the Massachusetts General Hospital and a professor of psychiatry at Harvard Medical School.
Obsessive–compulsive disorder (OCD) is a mental and behavioral disorder in which an individual has intrusive thoughts and feels the need to perform certain routines (compulsions) repeatedly to relieve the distress caused by the obsession, to the extent where it impairs general function.
Magnetic seizure therapy (MST) is a proposed form of electrotherapy and electrical brain stimulation. It is currently being investigated for the treatment of major depressive disorder, treatment-resistant depression (TRD), bipolar depression, schizophrenia and obsessive-compulsive disorder. MST is stated to work by inducing seizures via magnetic fields, in contrast to ECT which does so using alternating electric currents. Additionally, MST works in a more concentrated fashion than ECT, thus able to create a seizure with less of a total electric charge. In contrast to (r)TMS, the stimulation rates are higher resulting in more energy transfer. Currently it is thought that MST works in patients with major depressive disorder by activating the connection between the subgenual anterior cingulate cortex and the parietal cortex.
Yang Yongxin is a Chinese psychiatrist who advocated and practiced a highly controversial form of electroconvulsive therapy (ECT) without anesthesia or muscle relaxants as a cure for video game and Internet addiction in adolescents. Yang is currently deputy chief of the Fourth Hospital of Linyi, in the Shandong province of China. He runs the Internet Addiction Treatment Center at the hospital.
Cyclothymia, also known as cyclothymic disorder, psychothemia / psychothymia, bipolar III, affective personality disorder and cyclothymic personality disorder, is a mental and behavioural disorder that involves numerous periods of symptoms of depression and periods of symptoms of elevated mood. These symptoms, however, are not sufficient to indicate a major depressive episode or a manic episode. Symptoms must last for more than one year in children and two years in adults.
Melancholic depression, or depression with melancholic features, is a DSM-IV and DSM-5 specifier of depressive disorders. The specifier is used to distinguish clinically relevant subsets of causes and symptoms that have the potential to influence treatment.
Boy Interrupted is a 2009 documentary film on the life and death of Evan Perry, who experienced bipolar depression from a young age. When his parents, Dana and Hart Perry, consulted psychiatrists about Evan's suicidal comments or other signs of depression, medical professionals did not believe that he was mentally ill, and the footage was originally intended to show his symptoms and help access to the treatment he needed.
Schizophrenia is a primary psychotic disorder, whereas, bipolar disorder is a primary mood disorder which can also involve psychosis. Both schizophrenia and bipolar disorder are characterized as critical psychiatric disorders in the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5). However, because of some similar symptoms, differentiating between the two can sometimes be difficult; indeed, there is an intermediate diagnosis termed schizoaffective disorder.
