A label leads to a loss of information and overlooks the uniqueness of the person being studied or treated.

They may misinterpret typical body functions as signs of illness. Their persistent health worries can interfere with their relationships, careers and life. You may be more familiar with the term hypochondria or health anxiety.

Diagnosis 2.0: Are mental illnesses diseases, disorders, or syndromes?

Disease , any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury.

A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state. Thus, the normal condition of an organism must be understood in order to recognize the hallmarks of disease. Nevertheless, a sharp demarcation between disease and health is not always apparent. The study of disease is called pathology. It involves the determination of the cause etiology of the disease, the understanding of the mechanisms of its development pathogenesis , the structural changes associated with the disease process morphological changes , and the functional consequences of those changes.

Correctly identifying the cause of a disease is necessary to identifying the proper course of treatment. Humans, other animals , and plants are all susceptible to diseases of some sort. However, that which disrupts the normal functioning of one type of organism may have no effect on the other types. The normal state of an organism represents a condition of delicate physiological balance, or homeostasis , in terms of chemical, physical, and functional processes, maintained by a complex of mechanisms that are not fully understood.

In a fundamental sense, therefore, disease represents the consequences of a breakdown of the homeostatic control mechanisms. In some instances the affected mechanisms are clearly indicated, but in most cases a complex of mechanisms is disturbed, initially or sequentially, and precise definition of the pathogenesis of the ensuing disease is elusive. Death in humans and other mammals , for example, often results directly from heart or lung failure, but the preceding sequence of events may be highly complex, involving disturbances of other organ systems and derangement of other control mechanisms.

Finally, the disease may be caused by some agent external to the organism, such as a chemical that is a toxic agent. In this case the disease is noncommunicable; that is, it affects only the individual organism exposed to it. The external agent may be itself a living organism capable of multiplying within the host and subsequently infecting other organisms; in this case the disease is said to be communicable.

Noncommunicable diseases generally are long-lasting and progress slowly, and thus they are sometimes also referred to as chronic diseases. They can arise from environmental exposures or from genetically determined abnormalities, which may be evident at birth or which may become apparent later in life. The World Health Organization WHO has identified four major types of noncommunicable disease: cancer , cardiovascular disease e. WHO estimates that, combined, these four groups of conditions account for 82 percent of all deaths from noncommunicable disease.

Noncommunicable diseases that arise from inherited genetic abnormalities often leave an individual ill-equipped to survive without some form of treatment.

Examples of inherited disease include cystic fibrosis , Down syndrome , and inborn errors of metabolism , which are present at birth. Examples of inherited diseases that emerge in adulthood include Huntington disease and certain forms of cancer e. Disease Article Media Additional Info. Article Contents. Table Of Contents.

Do You Know The Difference Between Disease And Disorder?

A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not due to any immediate external injury. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency , hypersensitivity , allergies and autoimmune disorders. In humans, disease is often used more broadly to refer to any condition that causes pain , dysfunction , distress , social problems , or death to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries , disabilities , disorders , syndromes , infections , isolated symptoms , deviant behaviors , and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories.

Because differences are our greatest strength. We often hear the words speech and language used interchangeably. But in the medical community, they have very different meanings. Speech refers to the actual sound of spoken language. Speech is talking : using the muscles of the tongue, lips, jaw, and vocal tract in a very precise and coordinated way to produce the recognizable sounds that make up language.


While these two terms are often used interchangeably by doctors, there are subtle differences. A disease is distinct and measurable. A disorder might indicate that a specific disease is possible but there is not enough clinical evidence for diagnosis.


What’s the difference between a speech impairment and a language disorder?

Learn what a disease is and how it differs from a disorder, syndrome or condition. One of the original definitions of a disease was published in the British Medical Journal as early as Today, doctors treat and diagnose a disease based on abnormalities in systemic functions — for example, cardiovascular disease. These abnormalities can cause both physical and emotional signs and symptoms, as well as pain, dysfunction, distress, social problems or death.

What Is the Difference Between a Disease and a Disorder?

When a doctor suspects you have an autoimmune disease such as rheumatoid arthritis RA , you may hear them speak about your symptoms and diagnosis in various terms such as disease, disorder, syndrome, and condition. While these terms may seem interchangeable, they all refer to specific states of health. Symptom, syndrome, disorder, disease are all terms used as a hierarchy to classify how our health is affected. The symptoms are the first things we notice that indicate there might be a problem.

Which of these sentences is correct? As it happens, the first is an actual quote H. However, the question remains: What are the differences, if any, between disease and disorder? For that matter, where does the often-used condition fit in?
