Information: - Hyperthyroidism is the condition that occurs due to excessive production of thyroid hormone by the thyroid gland. Thyrotoxicosis is the condition that occurs due to excessive thyroid hormone of any cause and therefore includes hyperthyroidism. Some, however, use the terms interchangeably. Signs and symptoms vary between people and may include irritability, muscle weakness, sleeping problems, a fast heartbeat, heat intolerance, diarrhea, enlargement of the thyroid, and weight loss. Symptoms are typically less in the old and during pregnancy. An uncommon complication is thyroid storm in which an event such as an infection results in worsening symptoms such as confusion and a high temperature and often results in death. The opposite is hypothyroidism, when the thyroid gland does not make enough thyroid hormone. Graves' disease is the cause of about 50% to 80% of the cases of hyperthyroidism in the United States. Other causes include multinodular goiter, toxic adenoma, inflammation of the thyroid, eating too much iodine, and too much synthetic thyroid hormone. A less common cause is a pituitary adenoma. The diagnosis may be suspected based on signs and symptoms and then confirmed with blood tests. Typically blood tests show a low thyroid stimulating hormone (TSH) and raised T or T. Radioiodine uptake by the thyroid, thyroid scan, and TSI antibodies may help determine the cause. Treatment depends partly on the cause and severity of disease. There are three main treatment options: radioiodine therapy, medications, and thyroid surgery. Radioiodine therapy involves taking iodine-131 by mouth which is then concentrated in and destroys the thyroid over weeks to months. The resulting hypothyroidism is treated with synthetic thyroid hormone. Medications such as beta blockers may control the symptoms, and anti-thyroid medications such as methimazole may temporarily help people while other treatments are having effect. Surgery to remove the thyroid is another option. This may be used in those with very large thyroids or... - Electroconvulsive therapy (ECT), formerly known as electroshock therapy, and often referred to as shock treatment, is a psychiatric treatment in which seizures are electrically induced in patients to provide relief from psychiatric illnesses. The ECT procedure was first conducted in 1938 and is the only currently used form of shock therapy in psychiatry. ECT is often used with informed consent as a last line of intervention for major depressive disorder, mania, and catatonia. ECT machines have been placed in the Class III category (high risk) by the United States Food and Drug Administration (FDA) since 1976. - Anxiety disorders are a group of mental disorders characterized by feelings of anxiety and fear. Anxiety is a worry about future events and fear is a reaction to current events. These feelings may cause physical symptoms, such as a fast heart rate and shakiness. There are a number of anxiety disorders: including generalized anxiety disorder, specific phobia, social anxiety disorder, separation anxiety disorder, agoraphobia, panic disorder, and selective mutism. The disorder differs by what results in the symptoms. People often have more than one anxiety disorder. The cause of anxiety disorders is a combination of genetic and environmental factors. Risk factors include a history of child abuse, family history of mental disorders, and poverty. Anxiety disorders often occur with other mental disorders, particularly major depressive disorder, personality disorder, and substance use disorder. To be diagnosed symptoms typically need to be present at least six months, be more than would be expected for the situation, and decrease functioning. Other problems that may result in similar symptoms including hyperthyroidism, heart disease, caffeine, alcohol, or cannabis use, and withdrawal from certain drugs, among others. Without treatment, anxiety disorders tend to remain. Treatment may include lifestyle changes, counselling, and medications. Counselling is typically with a type of cognitive behavioural therapy. Medications, such as antidepressants or beta blockers, may improve symptoms. About 12% of people are affected by an anxiety disorder in a given year and between 5-30% are affected at some point in their life. They occur about twice as often in females as males, and generally begin before the age of 25. The most common are specific phobia which affects nearly 12% and social anxiety disorder which affects 10% at some point in their life. They affect those between the ages of 15 and 35 the most and become less common after the age of 55. Rates appear to be higher in the United States and Europe. - Alcoholism, also known as alcohol use disorder (AUD), is a broad term for any drinking of alcohol that results in problems. It was previously divided into two types: alcohol abuse and alcohol dependence. In a medical context, alcoholism is said to exist when two or more of the following conditions is present: a person drinks large amounts over a long time period, has difficulty cutting down, acquiring and drinking alcohol takes up a great deal of time, alcohol is strongly desired, usage results in not fulfilling responsibilities, usage results in social problems, usage results in health problems, usage results in risky situations, withdrawal occurs when stopping, and alcohol tolerance has occurred with use. Risky situations include drinking and driving or having unsafe sex among others. Alcohol use can affect all parts of the body but particularly affects the brain, heart, liver, pancreas, and immune system. This can result in mental illness, WernickeKorsakoff syndrome, an irregular heart beat, liver failure, and an increase in the risk of cancer, among other diseases. Drinking during pregnancy can cause damage to the baby resulting in fetal alcohol spectrum disorders. Generally women are more sensitive to alcohol's harmful physical and mental effects than men. Both environmental factors and genetics are associated with alcoholism with about half the risk attributed to each. A person with a parent or sibling with alcoholism is three to four times more likely to be alcoholic themselves. Environmental factors include social, cultural, and behavioral influences. High stress levels, anxiety, as well as inexpensive easily accessible alcohol increases risk. People may continue to drink partly to prevent or improve symptoms of withdrawal. A low level of withdrawal may last for months following stopping. Medically, alcoholism is considered both a physical and mental illness. Both questionnaires and certain blood tests may detect people with possible alcoholism. Further information is then collected to confirm the... - Pathology (from the Greek roots of "pathos", meaning "experience" or "suffering", and "-logia", "study of") is a significant component of the causal study of disease and a major field in modern medicine and diagnosis. - Suicide is the act of intentionally causing one's own death. Risk factors include mental disorders such as depression, bipolar disorder, schizophrenia, personality disorders, alcoholism, or substance misuse. Others are impulsive acts due to stress such as from financial difficulties, troubles with relationships, or from bullying. Those who have previously attempted suicide are at higher risk for future attempts. Suicide prevention efforts include limiting access to method of suicide, such as firearms and poisons, treating mental disorders and substance misuse, proper media reporting of suicide, and improving economic conditions. Although crisis hotlines are common, there is little evidence for their effectiveness. The most commonly used method of suicide varies between countries, and is partly related to the availability of effective means. Common methods include hanging, pesticide poisoning, and firearms. Suicide resulted in 842,000 deaths globally in 2013 (up from 712,000 deaths in 1990). This makes it the 10th leading cause of death worldwide. Approximately 0.5% to 1.4% of people die by suicide, about 12 per 100,000 persons per year. Three quarters of suicides globally occur in the developing world. Rates of completed suicides are generally higher in men than in women, ranging from 1.5 times as much in the developing world to 3.5 times in the developed world. Suicide is generally most common among those over the age of 70; however, in certain countries those aged between 15 and 30 are at highest risk. There are an estimated 10 to 20million non-fatal attempted suicides every year. Non-fatal suicide attempts may lead to injury and long-term disabilities. In the Western world, attempts are more common in young people and females. Views on suicide have been influenced by broad existential themes such as religion, honor, and the meaning of life. The Abrahamic religions traditionally consider suicide an offense towards God due to the belief in the sanctity of life. During the samurai era in Japan, a form of... - Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities. Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging. - Major depressive disorder (MDD), also known simply as depression, is a mental disorder characterized by at least two weeks of low mood that is present across most situations. It is often accompanied by low self-esteem, loss of interest in normally enjoyable activities, low energy, and pain without a clear cause. People may also occasionally have false beliefs or see or hear things that others cannot. Some people have periods of depression separated by years in which they are normal while others nearly always have symptoms present. Major depressive disorder can negatively affects a person's personal, work, or school life, as well as sleeping, eating habits, and general health. Between 27% of adults with major depression die by suicide, and up to 60% of people who die by suicide had depression or another mood disorder. The cause is believed to be a combination of genetic, environmental, and psychological factors. Risk factors include a family history of the condition, major life changes, certain medications, chronic health problems, and substance abuse. About 40% of the risk appears to be related to genetics. The diagnosis of major depressive disorder is based on the person's reported experiences and a mental status examination. There is no laboratory test for major depression. Testing, however, may be done to rule out physical conditions that can cause similar symptoms. Major depression should be differentiated from sadness which is a normal part of life and is less severe. The United States Preventive Services Task Force (USPSTF) recommends screening for depression among those over the age 12, while a prior Cochrane review found insufficient evidence for screening. Typically, people are treated with counselling and antidepressant medication. Medication appears to be effective, but the effect may only be significant in the most severely depressed. It is unclear whether medications affect the risk of suicide. Types of counselling used include cognitive behavioral therapy (CBT) and interpersonal therapy. If... - Bipolar disorder , also known as bipolar affective disorder or manic depression , is a mental disorder characterized by periods of elevated mood and periods of depression . The elevated mood is significant and is known as mania or hypomania depending on the severity or whether there is psychosis . During mania an individual feels or acts abnormally happy , energetic , or irritable . They often make poorly thought out decisions with little regard to the consequences . The need for sleep is usually reduced . During periods of depression there may be crying , poor eye contact with others , and a negative outlook on life . The risk of suicide among those with the disorder is high at greater than 6 % over 20 years , while self harm occurs in 30 -- 40 % . Other mental health issues such as anxiety disorder and substance use disorder are commonly associated . The cause is not clearly understood , but both genetic and environmental factors play a role . Many genes of small effect contribute to risk . Environmental factors include long term stress and a history of childhood abuse . It is divided into bipolar I disorder if there is at least one manic episode and bipolar II disorder if there are at least one hypomanic episode and one major depressive episode . In those with less severe symptoms of a prolonged duration the condition cyclothymic disorder may be present . If due to drugs or medical problems it is classified separately . Other conditions that may present in a similar manner include substance use disorder , personality disorders , attention deficit hyperactivity disorder , and schizophrenia as well as a number of medical conditions . Blood tests or medical imaging can be done to rule out other problems , although medical testing is not mandatory for a diagnosis . Treatment commonly includes psychotherapy and medications such as mood stabilizers or antipsychotics . Examples of mood stabilizers that are commonly used include lithium and anticonvulsants . Treatment in hospital against a person 's wishes may be... - A disease is a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism. The study of disease is called pathology which includes the causal study of etiology. Disease is often construed as a medical condition associated with specific symptoms and signs. It may be caused by external factors such as pathogens, or it may be caused by internal dysfunctions particularly of the immune system such as an immunodeficiency, or a hypersensitivity including allergies and autoimmunity.
