Health & MedicineBipolar Disorder
** Bipolar disorder (BD) is a chronic mood‑regulating condition marked by alternating episodes of depression and abnormally elevated mood (mania or hypomania), often accompanied by sleep disturbances, impulsivity, and heightened risk of suicide. **CONTENT:** ## Overview **Bipolar disorder** (formerly called manic‑depressive illness) is a neuropsychiatric condition that affects roughly 1–2 % of the global population. Individuals experience distinct mood episodes that can last from days to several weeks, and in some cases, months. A **depressive episode** is characterized by persistent sadness, loss of interest, fatigue, crying, negative self‑view, and often reduced eye contact. In contrast, a **manic episode** involves an abnormally high or irritable mood, inflated self‑esteem, decreased need for sleep, rapid speech, racing thoughts, and reckless behaviors such as overspending or unsafe driving. When the elevated mood is milder, does not cause marked functional impairment, and lasts at least four days, it is termed **hypomania**. The disorder is highly heterogeneous: some people cycle rapidly (multiple episodes per year), while others have long periods of stability between episodes. Sleep disruption is a hallmark of manic phases, with patients often feeling rested after only a few hours. The emotional volatility of BD contributes to a strikingly high risk of **suicide**—about 15–20 % of individuals with BD die by suicide, and 30–60 % attempt it at least once. Self‑harm behaviors are also common, affecting 40–50 % of all patients and up to 78 % of adolescents with the condition. Early recognition and comprehensive treatment are essential to reduce morbidity and mortality. ## History/Background The concept of alternating mood states dates back to ancient Greek physicians such as Hippocrates, who described “melancholia” and “mania” as separate illnesses. In the 19th century, French psychiatrist **Jean-Pierre Falret** coined the term “**circular insanity**” to capture the recurrent nature of mood swings. German psychiatrist **Emil Kraepelin** later distinguished **manic‑depressive illness** from schizophrenia, emphasizing its episodic course and biological underpinnings—a classification that persisted for decades. The mid‑20th century saw the introduction of **lithium**, the first mood‑stabilizing medication, dramatically improving outcomes and cementing BD as a treatable medical disorder. The 1970s and 1980s brought the development of **anticonvulsants** (e.g., valproate) and **atypical antipsychotics**, expanding the therapeutic arsenal. Diagnostic criteria were refined in successive editions of the **Diagnostic and Statistical Manual of Mental Disorders (DSM)**, with the current DSM‑5 distinguishing **Bipolar I**, **Bipolar II**, and **cyclothymic disorder** based on severity and duration of manic versus hypomanic episodes. Research into genetics, neuroimaging, and circadian biology continues to shape modern understanding. ## Key Information - **Epidemiology:** Affects ~1–2 % of adults worldwide; onset typically occurs in late adolescence or early adulthood, though pediatric cases are increasingly recognized. - **Subtypes:** - **Bipolar I:** At least one full **mania** episode (may be preceded or followed by depression). - **Bipolar II:** At least one **hypomania** episode and one major **depressive** episode, without full mania. - **Cyclothymic disorder:** Chronic, milder mood fluctuations that do not meet full criteria for mania or depression. - **Risk factors:** Family history, certain genetic markers, stressful life events, substance misuse, and sleep‑wake rhythm disruptions. - **Diagnosis:** Clinical interview, standardized rating scales (e.g., Young Mania Rating Scale, Montgomery‑Åsberg Depression Rating Scale), and exclusion of medical mimics (thyroid disease, neurologic disorders). - **Treatment:** A multimodal approach combining **mood stabilizers** (lithium, valproate, lamotrigine), **atypical antipsychotics**, **psychotherapy** (cognitive‑behavioral therapy, interpersonal‑social rhythm therapy), and lifestyle interventions (regular sleep, exercise, stress management). Psychoeducation and adherence monitoring are critical to prevent relapse. - **Prognosis:** With optimal treatment, many individuals achieve sustained remission and functional recovery, though the disorder is lifelong and relapse rates remain significant. **Important:** If you or someone you know exhibits signs of mania, severe depression, or suicidal thoughts, seek professional mental‑health care immediately. Early intervention can save lives. ## Significance Bipolar disorder’s impact extends beyond the individual to families, workplaces, and health systems. The high rates of **suicide** and **self‑harm** underscore a public‑health imperative for early detection, destigmatization, and accessible treatment. Economically, BD contributes to lost productivity, increased health‑care utilization, and substantial societal costs. Advances in pharmacogenomics and digital mood‑tracking tools hold promise for personalized care, while ongoing research into circadian biology may yield novel preventive strategies. Understanding BD also informs broader neuroscience, shedding light on the neural circuits that regulate emotion, reward, and cognition. Ultimately, comprehensive management of bipolar disorder improves quality of life, reduces mortality, and fosters societal inclusion for those living with this complex condition. **INFOBOX:** - Name: Bipolar disorder - Type: Mental health / Mood disorder - Date: First formally described in the late 19th century (Kraepelin, 1899) - Location: Global prevalence (affects individuals worldwide) - Known For: Alternating episodes of depression and elevated mood (mania/hypomania), high suicide risk, and response to mood‑stabilizing medications **TAGS:** bipolar disorder, mania, hypomania, depression, suicide risk, mood stabilizer, mental health, psychiatric epidemiology

** This encyclopedia entry is about a rare genetic disorder known as **Erythromelalgia** (EM), a condition characterized by burning pain, redness, and heat in the hands and feet. ## Overview Erythromelalgia (EM) is a rare genetic disorder affecting approximately 1.3 people per 100,000 worldwide. It is characterized by episodes of intense burning pain, redness, and heat in the hands and feet, often accompanied by increased skin temperature. The condition is usually diagnosed in childhood or adolescence, but it can also occur in adults. Erythromelalgia is often misdiagnosed as other conditions, such as neuropathy, arthritis, or vasculitis, due to its complex symptoms. The symptoms of EM can vary in severity and frequency, but they often worsen with heat, exercise, or stress. People with EM may experience episodes of intense pain, which can be debilitating and disrupt daily activities. In some cases, the condition can lead to anxiety, depression, or social isolation due to the impact on daily life. ## History/Background Erythromelalgia was first described in the late 19th century by a German physician, Dr. Hermann Oppenheim. However, it was not until the 1970s that the condition gained more attention, and its genetic basis was identified. In 1975, a study published in the **Journal of Neurology** found that EM was associated with a mutation in the **ATP6V0A2** gene, which codes for a protein involved in sodium-potassium transport in the skin. ## Key Information * **Causes:** Erythromelalgia is caused by a mutation in the **ATP6V0A2** gene, which leads to impaired sodium-potassium transport in the skin. * **Symptoms:** Burning pain, redness, and heat in the hands and feet, often accompanied by increased skin temperature. * **Diagnosis:** EM is diagnosed based on a combination of clinical evaluation, medical history, and genetic testing. * **Treatment:** Treatment options for EM include medications to manage pain, reduce inflammation, and regulate body temperature. * **Complications:** Untreated EM can lead to anxiety, depression, social isolation, and decreased quality of life. ## Significance Erythromelalgia is a significant condition due to its impact on daily life and quality of life.

** Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain, fatigue, and cognitive difficulties, affecting millions of people worldwide. **CONTENT:** ### Overview Fibromyalgia is a complex and multifaceted condition that affects the nervous system, causing widespread pain, fatigue, and cognitive difficulties. It is estimated that over 10 million people in the United States alone suffer from fibromyalgia, making it one of the most common chronic pain conditions. Despite its prevalence, fibromyalgia remains poorly understood, and its exact causes and mechanisms are still not fully understood. However, research has made significant progress in identifying the key factors that contribute to the development of fibromyalgia. Fibromyalgia is often described as a "central sensitization" disorder, meaning that the nervous system becomes overly sensitive to pain signals, leading to an amplified response to stimuli. This can result in a range of symptoms, including muscle pain, joint pain, headaches, fatigue, sleep disturbances, and cognitive difficulties such as memory and concentration problems. The symptoms of fibromyalgia can vary from person to person, and can be triggered by a range of factors, including stress, trauma, and certain medical conditions. ### History/Background The concept of fibromyalgia dates back to the 19th century, when it was described as a condition characterized by widespread muscle pain and fatigue. However, it wasn't until the 1990s that fibromyalgia was recognized as a distinct medical condition. In 1990, the American College of Rheumatology (ACR) established a set of criteria for diagnosing fibromyalgia, which included widespread pain, fatigue, and cognitive difficulties. Since then, research has continued to shed light on the causes and mechanisms of fibromyalgia, leading to a greater understanding of this complex condition. ### Key Information * **Prevalence:** Fibromyalgia affects an estimated 10 million people in the United States, and millions more worldwide. * **Symptoms:** Widespread pain, fatigue, sleep disturbances, cognitive difficulties, and other symptoms. * **Causes:** Unknown, but thought to involve a combination of genetic, environmental, and psychological factors. * **Diagnosis:** Based on a combination of medical history, physical examination, and laboratory tests. * **Treatment:** May include medication, physical therapy, cognitive-behavioral therapy, and lifestyle changes. ### Significance Fibromyalgia has significant implications for individuals and society as a whole.
