2、twork of neurons in our brain fails to function normally, the result can be a near-endless variety and combinations of mental illnesses.Its normal to sometimes be sad, happy, anxious, confused, forgetful or fearful, but when a persons emotions, thoughts or behavior frequently trouble them, or disrup
3、t their lives, they may be suffering from mental illness. According to the World Health Organization (WHO), about 450 million people worldwide are affected by mental, neurological or behavioral problems at any time.However, determining that someone has a mental illness, and which one, is one of the
4、challenges psychiatrists face. One effort to catalogue these afflictions is the “psychiatrists bible“, the Diagnostic and Statistical Manual of Mental Disorders-the latest edition fills nearly one thousand pages and lists over 400 disorders.BDiversity of disorders/BAmong the best known and most comm
5、on mental illnesses is depression-a prolonged, weakening sad- ness, sometimes accompanied by a feeling of hopelessness and thoughts of suicide. Seasonal affective disorder is a type of depression that affects some people in the autumn and winter and is triggered by the disappearing hours of daylight
6、 and colder temperatures. In bipolar disorder (双极性障碍), a person changes from depression to episodes of excessive enthusiasm where they are unrealistically confident in their abilities.Personality disorders are behavior patterns that are destructive to the person themselves or those around them. In d
7、issociative disorders, someone experiences a sudden change in consciousness or their concept of self. In dissociative amnesia, for example, the result is a loss of part or all of their memories. Samson, the Biblical strongman, may have suffered from the earliest recorded case of antisocial personali
8、ty disorder.Anxiety disorders are characterized by powerful feelings of stress and physical signs of fear-sweating, a racing heart-due to some cue in the environment, or for no obvious reason at all. These include post-traumatic (创伤后的) stress disorder, panic disorder, obsessive compulsive disorder,
9、anger disorders, hypochondria, social phobia, and other phobias including agoraphobia (open spaces), claustrophobia (small spaces), acrophobia (heights), and arachnophobia (spiders).Attention-deficit hyperactivity disorder is among the most common mental illnesses diagnosed in children, affecting th
10、eir ability to focus and associated with high levels of activity and impulsiveness.Eating disorders involve an unhealthy relationship to food. A sufferer of anorexia nervosa (神经性厌食症) will strive for thinness to the point of starvation, due to a distorted perception of their bodies and dissatisfactio
11、n in their sense of control. They engage in cycles of gorging(feed greedily) themselves and then purging through vomiting or the use of some drugs. Muscle dysmorphia is sometimes thought of as a “reverse“ form of anorexia that affects bodybuilders. Sufferers constantly worry that they are too weak d
12、espite being extremely strong.BEnormous cost/BMental illnesses are quite common. As many as one in five people are thought to suffer from mental illness, at least temporarily, each year. Suicide-often the result of untreated mental illness-claims 873000 lives around the world each year. The economic
13、 costs of these conditions are also enormous and growing. According to the WHO, depression is expected to account for more lost years of healthy life than any other disease by 2030, except for HIV/AIDS.Even so, the mentally ill face disgrace and discrimination. Studies find people are reluctant to a
14、dmit they have at mental illness, to seek help, or to stick with treatment. Others are eager to reject the label of a mental illness. For example, some people with autism characterized by difficulty communicating or socializing insist the condition is not a disorder that needs to be cured, but just
15、part of normal human “neurodiversity“.BUnderlying causes/BHistorically, some symptoms of mental illness, such as irregular behaviour and hearing voices, have been taken as evidence of heavenly communication or possession of magical power. More recently, brain scans have directly linked these conditi
16、ons with changes in levels of neurotransmitters chemicals that convey messages across neurons-or alterations in the number or structure of neurons in different brain areas. For instance, people suffering from depression often display lowered levels of the neurotransmitter serotonin.In a few cases, t
17、he immediate cause of the malfunction has been identified. Alzheimers disease, a major source of dementia and memory loss ill the elderly, is caused by the accumulation of protein plaques which choke neurons in the brain.Some infectious diseases can also develop into a mental illness. Untreated HIV
18、infection can cause dementia, as can the uncontrolled replication of the microbe that causes syphilis. Borrelia burgdorferi-the Lyme disease bacterium, responsible for malaria (fever transmitted by mosquitoes), are also thought capable of triggering a variety of mental illnesses.In many cases the pr
19、ecise cause is unclear and experts suspect that many different factors are involved. One striking example is schizophrenia (精神分裂症), distinguished by psychosis. This is a distorted view of reality, which may include hallucinations (illusion of seeing or hearing something not actually present), hearin
20、g voices, delusions, and paranoia. The chance that identical twins both develop schizophrenia is much higher than that for fraternal twins or siblings, arguing for the strong role of inherited genes. But scientists are accumulating a growing list of other risk factors that predispose people to this
21、condition, including exposure to famine conditions before birth, certain infections or exposure to lead. The season of their birth also seems important-birth in winter or early spring increases the risk, as does an older father and, controversially, child abuse.Genes are also thought to influence ma
22、ny other mental health problems, including: anorexia, autism, Alzheimers disease and bipolar disorder. Besides, the womb environment, exposure to X-rays, being held in detention centres and having an overactive immune system are also some influencing factors.Some researchers believe that smoking cig
23、arettes and taking recreational drugs like LSD, ecstasy and cannabis, may elevate a users risk of mental illnesses, including schizophrenia, although it can be difficult to assess whether drug use is a cause or effect. And careful use of LSD and ecstasy might even help treat psychiatric problems.BPs
24、ychiatric treatments/BPsychiatric treatment for mental illness can take many forms. In psychotherapy, the patient is encouraged to recognize their problems, understand what may trigger undesirable behavior, and develop coping strategies.Many medications are also available to treat some of the most s
25、evere symptoms. Recently, however, some experts think there has been a rush to medicate every disorder and have questioned the effectiveness of many drugs. There is also controversy about using these drugs-such as Ritalin or amphetamines-to treat children.Other less mainstream treatments for mental
26、health problems, include stimulating the brain with magnetic pulses, electroconvulsive therapy, deep brain electrode stimulation, staying at a Hindu temple and using virtual reality to treat schizophrenia and phobias. Some experts argue that the different treatments for depression share a common mec
27、hanisms-prompting the growth of neurons. BMadly creative/BMadness has long been linked with genius. Many famous artists, writers and scientists have suffered from mental disorders, leading some to wonder if there is a link between these illnesses and creativity.The mathematician John Nash struggled
28、with schizophrenia while he developed the theory that earned him a Nobel Prize. The artist Vincent Van Gogh, the composer Robert Schumann and the writer Fyodor Dostoevsky are said to have suffered from a range of mental disorders including hypergraphia, a compulsion to write-a sign perhaps their art
29、 emerged from an unrelenting urge to communicate.One possibility is that genes that predispose people to such devastating illnesses persist because when the syndromes are present in a milder form, this heightened creativity gives people an evolutionary advantage.（分数：70.00）(1).Mental illness may be r
