Chronic fatigue syndrome
Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a medical condition characterized by long-term fatigue and other symptoms that limit a person's ability to carry out ordinary daily activities. Biological, genetic, infectious, and psychological mechanisms have been proposed, but the cause is not understood. Diagnosis is based on a person's symptoms. The fatigue is not due to strenuous ongoing exertion, is not much relieved by rest, and is not due to a previous medical condition. Fatigue is a common symptom in many illnesses, but the unexplained fatigue and severity of functional impairment in CFS is comparatively rare.
History of chronic fatigue syndrome
The history of chronic fatigue syndrome (CFS, also known by many other names) is thought to date back to the 19th century and before. Several descriptions of illness resembling those of chronic fatigue syndrome have been reported for at least two hundred years. In the 19th century, neurologist George Miller Beard popularised the concept of neurasthenia, with symptoms including fatigue, anxiety, headache, impotence, neuralgia and depression. This concept remained popular well into the 20th century, eventually coming to be seen as a behavioural rather than physical condition, with a diagnosis that excluded postviral syndromes.
Clinical descriptions of chronic fatigue syndrome
The clinical descriptions of chronic fatigue syndrome (CFS) vary. Different agencies and scientific bodies have produced different guidelines to define the condition, with some overlap of symptoms between descriptions. Aspects of the condition are controversial, with disagreements over etiology, pathophysiology, treatment and naming between medical practitioners, researchers, patients and advocacy groups. Subgroup analysis suggests that, depending on the applied definition, the CFS population may represent a variety of conditions rather than a single disease entity. The most widely used diagnostic criteria for CFS are the 1994 research guidelines proposed by the "International Chronic Fatigue Syndrome Study Group", led by the Centers for Disease Control and Prevention.
Chronic fatigue syndrome treatment
Treatment of chronic fatigue syndrome (CFS) is variable and uncertain, and the condition is primarily managed rather than cured. Only two treatments, cognitive behavioral therapy and graded exercise therapy, have demonstrated reproducible evidence for their efficacy people with CFS who are walking. There are no Food and Drug Administration (FDA) approved medications for ME/CFS treatment, although medications are used without approval for the illness (off-label). Drugs have been used in experimental studies of the illness that haven't been approved for market for any condition in the United States (for example, isoprinosine and rintatolimod).
Controversies related to chronic fatigue syndrome
Chronic fatigue syndrome (CFS) is an illness with a long history of controversy. For years, many professionals within the medical community did not recognize CFS as a true condition, nor was there agreement on its prevalence. There has been much disagreement over the pathophysiology of chronic fatigue syndrome, how it should be diagnosed, and how to treat it. The diagnosis is controversial, and its etiology is still not fully understood. Alternative names to describe the condition(s) have been used over time throughout the world. Patient groups have criticized the name "chronic fatigue syndrome," saying it trivializes the illness.
Fibromyalgia
Fibromyalgia (FM) is a medical condition characterised by chronic widespread pain and a heightened pain response to pressure. Other symptoms include tiredness to a degree that normal activities are affected, sleep problems, and troubles with memory. Some people also report restless legs syndrome, bowel or bladder problems, numbness and tingling, and sensitivity to noise, lights or temperature. Fibromyalgia is frequently associated with depression, anxiety, and posttraumatic stress disorder. Other types of chronic pain are also frequently present. The cause of fibromyalgia is unknown; however, it is believed to involve a combination of genetic and environmental factors with half the risk attributed to each.
Daniel Peterson (physician)
Daniel Peterson is an American physician in private practice in the state of Nevada, and has been described as a "pioneer" in the treatment of chronic fatigue syndrome (CFS). He graduated from the University of Rochester School of Medicine, Rochester, New York, in 1976 and was an intern and resident at the University of Utah Medical Center from 1976 to 1979. In 1979, he became a Diplomat of the American Board of Internal Medicine. He is president of Sierra Internal Medicine of Incline Village, established in 1981. Along with Paul Cheney, Peterson was a treating physician at Incline Village during an outbreak of chronic fatigue syndrome that began in 1984 in the Lake Tahoe region.

Well we don't really know how it is cause, but there are alot of different potential causes like genetics and biology. 
Biological, genetic, infectious, and psychological mechanisms have been proposed, but the cause is not understood.

Teleological argument
The teleological or physico-theological argument, also known as the argument from design, or intelligent design argument is an argument for the existence of God or, more generally, for an intelligent creator based on perceived evidence of deliberate design in the natural world. The earliest recorded versions of this argument are associated with Socrates in ancient Greece, although it has been argued that he was taking up an older argument. Plato, his student, and Aristotle, Plato's student, developed complex approaches to the proposal that the cosmos has an intelligent cause, but it was the Stoics who, under their influence, "developed the battery of creationist arguments broadly known under the label 'The Argument from Design.
History of evolutionary thought
Evolutionary thought, the conception that species change over time, has roots in antiquity - in the ideas of the ancient Greeks, Romans, and Chinese as well as in medieval Islamic science. With the beginnings of modern biological taxonomy in the late 17th century, two opposed ideas influenced Western biological thinking: essentialism, the belief that every species has essential characteristics that are unalterable, a concept which had developed from medieval Aristotelian metaphysics, and that fit well with natural theology; and the development of the new anti-Aristotelian approach to modern science: as the Enlightenment progressed, evolutionary cosmology and the mechanical philosophy spread from the physical sciences to natural history.
Spinocerebellar ataxia type 1
Spinocerebellar Ataxia type 1 (SCA1) is a rare autosomal dominant disorder, which, like other spinocerebellar ataxias, is characterized by dysarthria, hypermetric saccades, ataxia of gait and stance, and other neurological symptoms. This cerebellar dysfunction is progressive and permanent. First onset of symptoms is normally between 30 and 40 years of age, though juvenile onset can occur. Death typically occurs within 10 to 30 years from onset. SCA1 is typically inherited from the parents in an autosomal dominant regime; the children of a person with the disease have a 50% chance of inheriting it themselves and new mutations can occur in some cases.
History of biology
The history of biology traces the study of the living world from ancient to modern times. Although the concept of "biology" as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to ayurveda, ancient Egyptian medicine and the works of Aristotle and Galen in the ancient Greco-Roman world. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna. During the European Renaissance and early modern period, biological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms.
Ma'alot-Tarshiha
Ma'alot-Tarshiha (; , "Maʻālūt Taršīḥā") is a mixed city in the North District in Israel, some east of Nahariya, about above sea level. The city was established in 1963 through a municipal merger of the Arab town of Tarshiha and the Jewish town of Ma'alot. In the city has a population of . Excavations of a 4th-century burial cave in the village unearthed a cross and a piece of glass engraved with a menorah. Crusader sources from the 12th and 13th century refer to Tarshiha as "Terschia," "Torsia" and "Tersigha." The King had initiated the settlement of Crusader ("Latin", "Frankish") people in nearby Mi'ilya ("Castellum Regis"), and from there settlement spread out to Tarshiha.
Alot
Alot () is a town and nagar panchayat in the Ratlam district of Madhya Pradesh, India. Alot is located at . Alot has a population of 40,948. Alot is a tehsil place and a small town; it is a tahsil of Ratlam district and the hometown to Jangalwa Dynasty. It is on the route of the Delhi–Bombay railway track. Through trade routes Jewellers and Businessman established themselves in the town before the 17th century and flourished businesses in ginning and jewellery. A glimpse of the business lifestyle during that era can still be found in the historical town. Alot is a main station for Jain ; many Jain people go there daily for the darshan of Lord Jain Swetamber.
Free will
Free will is the ability to choose between different possible courses of action unimpeded. Free will is closely linked to the concepts of responsibility, praise, guilt, sin, and other judgements which apply only to actions that are freely chosen. It is also connected with the concepts of advice, persuasion, deliberation, and prohibition. Traditionally, only actions that are freely willed are seen as deserving credit or blame. There are numerous different concerns about threats to the possibility of free will, varying by how exactly it is conceived, which is a matter of some debate. Some conceive free will to be the capacity to make choices in which the outcome has not been determined by past events.

Yeah its diagnosed using a person's symptoms like most conditions. 
Diagnosis is based on a person's symptoms.

Attention deficit hyperactivity disorder
Attention deficit hyperactivity disorder (ADHD) is a mental disorder of the neurodevelopmental type. It is characterized by problems paying attention, excessive activity, or difficulty controlling behavior which is not appropriate for a person's age. The symptoms appear before a person is twelve years old, are present for more than six months, and cause problems in at least two settings (such as school, home, or recreational activities). In children, problems paying attention may result in poor school performance. Although it causes impairment, particularly in modern society, many children with ADHD have a good attention span for tasks they find interesting.
Post-concussion syndrome
Post-concussion syndrome, also known as postconcussive syndrome or PCS, is a set of symptoms that may continue for weeks, months, or a year or more after a concussion – a mild form of traumatic brain injury (TBI). The rates of PCS vary, but most studies report that about 15% of individuals with a history of a single concussion develop persistent symptoms associated with the injury. A diagnosis may be made when symptoms resulting from concussion last for more than three months after the injury. Loss of consciousness is not required for a diagnosis of concussion or post-concussion syndrome. The condition is associated with a wide range of symptoms: physical, such as headache; cognitive, such as difficulty concentrating; and emotional and behavioral, such as irritability.
Schizoaffective disorder
Schizoaffective disorder (SZA, SZD or SAD) is a mental disorder characterized by abnormal thought processes and deregulated emotions. The diagnosis is made when the person has features of both schizophrenia and a mood disorder—either bipolar disorder or depression—but does not strictly meet diagnostic criteria for either alone. The bipolar type is distinguished by symptoms of mania, hypomania, or mixed episode; the depressive type by symptoms of depression only. Common symptoms of the disorder include hallucinations, paranoid delusions, and disorganized speech and thinking. The onset of symptoms usually begins in young adulthood, currently with an uncertain lifetime prevalence because the disorder was redefined, but DSM-IV prevalence estimates have been less than one percent of the population, in the range of 0.5 to 0.8 percent.
Neuroferritinopathy
Neuroferritinopathy or adult-onset basal ganglia disease is a genetic neurodegenerative disorder characterized by the accumulation of iron in the basal ganglia, cerebellum, and motor cortex of the human brain. Symptoms, which are extrapyramidal in nature, progress slowly and generally do not become apparent until adulthood. These symptoms include chorea, dystonia, and cognitive deficits which worsen with age. This disorder is autosomal dominant and is caused by mutations in the gene encoding the light chain subunit of the ferritin protein. Wild type ferritin functions as a buffer for iron, sequestering it and controlling its release.
Psychosis
Psychosis is an abnormal condition of the mind that results in difficulties telling what is real and what is not. Symptoms may include false beliefs and seeing or hearing things that others do not see or hear. Other symptoms may include incoherent speech and behavior that is inappropriate for the situation. There may also be sleep problems, social withdrawal, lack of motivation, and difficulties carrying out daily activities. Psychosis has many different causes. These include mental illness, such as schizophrenia or bipolar disorder, sleep deprivation, some medical conditions, certain medications, and drugs such as alcohol or cannabis.
Cerebral palsy
Cerebral palsy (CP) is a group of permanent movement disorders that appear in early childhood. Signs and symptoms vary among people. Often, symptoms include poor coordination, stiff muscles, weak muscles, and tremors. There may be problems with sensation, vision, hearing, swallowing, and speaking. Often babies with cerebral palsy do not roll over, sit, crawl, or walk as early as other children of their age. Other symptoms may include seizures and problems with thinking or reasoning, either of which occurs in about one third of people with CP. While the symptoms may get more noticeable over the first few years of life, the underlying problems do not worsen over time.
Dissociative identity disorder
Dissociative identity disorder (DID), also known as multiple personality disorder, is a mental disorder characterized by at least two distinct and relatively enduring personality states. There is often trouble remembering certain events, beyond what would be explained by ordinary forgetfulness. These states alternately show in a person's behavior. Presentations, however, are variable. Associated condition often include borderline personality disorder, post traumatic stress disorder, depression, substance misuse disorder, self-harm, or anxiety. The cause is believed to be due to childhood trauma.
