What are the symptoms of chronic fatigue syndrome?
Chronic fatigue syndrome, also known as CFS or myalgic encephalomyelitis, is a disorder that is not well understood. The symptoms of chronic fatigue syndrome, which include fatigue and joint and muscle pain, occur without the cause or apparent trigger. Although there are some strong theories that indicate a special cause of the disorder, there are still no clear answers. The classic feature is simply fatigue, but fatigue itself does not necessarily indicate CFS. For diagnostic purposes, fatigue must be present for at least six months before diagnosis. In addition, there must be no other cause that could explain the presence of fatigue. In some people, fatigue may monitor viral infection, but previous viral infection is not present in all cases.
Fatigue that occurs with CFS has different common properties. One of them is the post-eeral tukigue, which means that people with CFS are exhausted after activities that would not be tired before the development of CFS. Another characteristicU is that people with CFS are not refreshed by sleep or rest. Other common symptoms of chronic fatigue syndrome include muscle and joint pain, headaches, fever and sore throat.
People with CFS can also suffer from neurological problems. One of them is a cognitive disorder called dysnomy. People with this disorder have difficulty in language and have problems thinking about the right words that can be used in speaking. Memory dysfunction is also common; However, it tends to suffer only short -term memory, while long -term memory is preserved. Depression is another neurological symptom that may result from CFS, but the disorder does not cause depression. Instead, depression tends to develop as a result of problems that people with CFS face every day.
Because the cause of the disorder is unknown, the same question is what causes symptoms of chronic fatigue syndrome. One of the strongest theories on the cause of CFS is teOrie central sensitization that describes a specific type of abnormal immune reaction. When the body is in the state of central sensitization, the result is a chronically active immune system. In fact, the immune system behaves as if it were constantly fighting against infection. This may partially explain why intense fatigue is one of the characteristic symptoms of chronic fatigue syndrome, as the body can spend a large amount of energy to fight the infection.
