Medically unexplained physical symptoms (MUPS or MUS) are symptoms for which a treating physician or other healthcare providers have found no medical cause, or whose cause remains contested. [1] In its strictest sense, the term simply means that the cause for the symptoms is unknown or disputed—there is no scientific consensus .
Signs and symptoms are also applied to physiological states outside the context of disease, as for example when referring to the signs and symptoms of pregnancy, or the symptoms of dehydration. Sometimes a disease may be present without showing any signs or symptoms when it is known as being asymptomatic . [ 13 ]

He listed symptoms such as "behavioral changes, sleep disturbances, unexplained pain, visual hallucinations, coordination problems, unexplained hair loss, involuntary muscle twitching, formication (a sensation that feels like small insects crawling under the skin), ataxia ...
Relatedly, when disease is widespread, epidemiological studies investigate what associated factors, such as location, sex, exposure to chemicals, and many others, make a population more or less likely to have an illness, condition, or disease, thus helping determine its etiology. Sometimes determining etiology is an imprecise process.
Functional weakness is weakness of an arm or leg without evidence of damage or a disease of the nervous system. Patients with functional weakness experience symptoms of limb weakness which can be disabling and frightening such as problems walking or a 'heaviness' down one side, dropping things or a feeling that a limb just doesn't feel normal or 'part of them'.
Overdiagnosis is the diagnosis of "disease" that will never cause symptoms or death during a patient's lifetime. [9] It is a problem because it turns people into patients unnecessarily and because it can lead to economic waste [10] (overutilization) and treatments that may cause harm. Overdiagnosis occurs when a disease is diagnosed correctly ...
Also called silent disease, silent stage, or asymptomatic disease. This is a stage in some diseases before the symptoms are first noted. [23] Terminal phase If a person will die soon from a disease, regardless of whether that disease typically causes death, then the stage between the earlier disease process and active dying is the terminal phase.
An idiopathic disease is any disease with an unknown cause or mechanism of apparent spontaneous origin. [ 1 ] For some medical conditions, one or more causes are somewhat understood, but in a certain percentage of people with the condition, the cause may not be readily apparent or characterized.
