Tiersky et al. A 10 year follow-up of the outbreak at West Otago, New Zealand also reported a good prognosis. Though some needed to adapt their lifestyle to prevent relapses, most patients returned to premorbid activity. Follow-up data is also available for the outbreak in Akureyri, Iceland. After an average of 2. Eighty-eight percent reported recovery, though this information has not been reported in a peer-review publication.
A comparison showed few meaningful differences. But when limited to those patients who had been sick for a long time, younger patients did have more autonomic and immune -related symptoms.
Although many physicians believe that patients would benefit from earlier diagnosis and treatment, evidence for this is currently lacking. Many studies have found that illness severity at baseline is associated poorer outcomes over time. Disagreement exists however on which measures of illness best predict a worse prognosis. While Pheley et al. One well-controlled study Tiersky et al. After 6. DeLuca et al.
Ciccone et al. Hamilton et al. To estimate prognosis they looked at the percentage of patients who retained the label of any of these " fatiguing illnesses " at follow-up. Most studies have not found gender to be a significant predictor of prognosis more references needed.
Finally Adamowicz et al. This was seen in a Norwegian study that used multiple measures of recovery. While the total sleep and rest time decreased, work disability increased.
While attention during reading worsened, difficulty in driving a car improved. Twisk argued that objective measures such as a cardiopulmonary exercise test , a tilt table test or neurocognitive tests , should be used to assess recovery. In the s, Patricia Fennell for example suggested four distinct stages. In the second phase, the diagnosis has provided a kind of relief, while the disease usually stabilizes.
In the third phase, patients understand that they will not recover quickly and that their disease is chronic. At this stage patients go through a mourning process as they realize that their old self is gone and they have to adapt to a new identity. Although the illness is stable, they still experience relapses.
In the fourth phase, the patients reintegrate with their new identity; they set new goals and value a new way of living. Some experience improvement. Jason et al. Though analysis showed a three-factor solution that corresponded with Fennell's stages, almost none of the patients were in the fourth stage.
The analysis also showed that patients experiencing the first phase, the crisis phase, were sick for a longer time than patients in other stages. This suggests Fennell's subdivisions should not be seen as a linear development in time, but rather the progression patients make in dealing with illness and disability.
The initial virus likely fades away in a week and the patient feels better and is ready for regular activities. Bell adds "in a person with a gradual onset of symptoms, this stage would be different. There is little variation day-to-day, and this time is very confusing. Many medical providers are contacted, most giving conflicting opinions varying from psychological disorders to possible exotic infections, but the tests come back normal. Patients may look well and recovery is thought to have taken place, but they still have to adapt their lifestyle to avoid relapses and symptom exacerbation.
It operates under the auspices of the Department of Health and Human Services. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain myalgia , trouble remaining upright orthostatic intolerance , sleep abnormalities, and gastro-intestinal impairments, among others. Table 2: Category II medications with response rate, remission, time to remission and level of evidence.
View Table 2. Furthermore, not all studies investigating the above treatments were conducted in a large-scale and double-blinded setting. The following criteria were adopted for the inclusion of drugs in Category III:. Table 3 shows 5 medications that meet the inclusion criteria for Category III treatment;.
Table 3: Category III medications with response rate, remission, time to remission and level of evidence. View Table 3. The following criteria were adopted for the inclusion of drugs in Category IV:. A total of 31 supplements fall in this category. Additionally, there are 6 pharmaceutical formulations Naphazoline, Piracetam, Pentoxifylline, Azithromycin, Guaifenesin, Fludrocortisone that fulfill the inclusion criteria for Category IV treatment regimen.
However, the effectiveness of these supplements and pharmaceuticals has not been published or investigated in scientific studies and their evidence is hypothetical, informal, or based on expert opinion of medical professionals only. However, surveys from patient organizations have found considerable rates of harm from CBT in CFS patients [ 50 , 51 ].
Moreover, the two largest UK patient charities, ME Association and Action for ME, have called for the use of CBT to challenge "illness beliefs" to be withdrawn and for health care providers to warn patients of the potential for harm [ 52 ].
Older age, longer duration of symptoms, severity, comorbid psychiatric illness, and poor physical health status are additional factors that worsen the prognosis. Children and adolescents appear to recover more rapidly and have a low incidence of recurrence [ 56 ]. However, the study failed to identify predictors for recovery [ 57 ]. Furthermore, prompt diagnosis and early treatment significantly raises the rate and pace of recovery [ 54 , 58 ].
The evidence suggests the 10 different agents as the most effective treatments for CFS. Furthermore, the evidence suggests the following 10 different agents as the most effective treatments for CFS. There are certain limitations to this review. However, most of the above studies were conducted over the time span of a few weeks to 6 months, which should alleviate this limitation. Chronic fatigue syndrome is also known as myalgic encephalopathy or ME although not everyone agrees that these are the same condition.
It is accompanied by other symptoms including impaired memory or concentration, sore throat, tender lymph nodes, headaches and joint and muscle pain. The symptoms are very similar to those of flu, and in many cases chronic fatigue does seem to be triggered by viral infections such as glandular fever although not flu. The body seems to clear the viral infection, but the fatigue stays.
Medical authorities now agree that it is a genuine, discrete condition, even though its causes are debated, but many sufferers still feel they are dismissed as hypochondriacs who need to pull themselves together. Tim Noakes, a sports physiologist at the University of Cape Town, South Africa, became interested in chronic fatigue after seeing athletes affected by it and realised that it did not fit this stereotype. He believes the answer to the condition lies in the brain.
His work studying athletes with a colleague, Alan St Clair Gibson, left them both convinced that, although there is a physical limit to what the body can achieve, the brain acts in advance of this limit, making us feel tired before any signs of damage occur. Most of the research into the idea of a central governor involves subtle shifts at the very limits of performance, often in elite athletes.
But what happens if that entire system crashes? The fatigue that normally protects us from pushing ourselves too far might instead become a prison. Whatever the trigger — virus, overwork, a genetic predisposition or most likely a combination of several factors — Noakes argues that in chronic fatigue the boundaries of physical activity narrow tremendously, to the point where patients are essentially immobilised.
But it does hint that their condition might be influenced by psychological factors. Indeed, one of the most robust scientific findings regarding chronic fatigue is that, when patients are convinced that their condition is biological and untreatable, and fear that engaging in activity will be harmful, they are much less likely to recover.
If interval training works for athletes by teaching the central governor that ever-greater levels of exertion are safe, might it also work for patients with chronic fatigue syndrome? Samantha Miller made a deal with her partner and her sister.
Please, just give him six months, they said. Independently of Noakes, White was developing similar ideas about chronic fatigue. To try to reverse the change, he developed with colleagues an approach called graded exercise therapy GET , which is intended to work like an ultra-gentle form of interval training.
The idea is to set a baseline of activity that the patient can maintain safely, then gradually increase it. Each step has to be small, so as not to risk a relapse. Patients report feeling vastly more fatigued than healthy people for a set level of exercise. But White has shown that, after a course of GET, they feel less tired after the same amount of exercise, even though their physical fitness is unchanged.
White also uses cognitive behavioural therapy CBT , in which therapists work with patients to challenge negative ideas and beliefs that they have about their illness. People with M.

The prognosis for an improvement in symptoms is less gloomy.
