An abnormality or deviation from normal structure and function of the mind or the body is termed as a disease.
This can include a physical or physiological injury or malfunction.
A disease exhibits symptoms or manifestations that can be used to identify it. Therefore, the normal structure and function must also be studied.
The scientific study of diseases is called pathology. This includes investigating the cause or etiology of the disease as well as its pathogenesis, treatment and prognosis.
