What term refers to the remedial treatment of a disease or disorder?

The term that refers to the remedial treatment of a disease or disorder is therapy. Therapy encompasses a wide range of treatments designed to alleviate symptoms, heal ailments, and improve patients' well-being. It can include various methods, such as medication, physical rehabilitation, psychological counseling, and other interventions tailored to address specific health issues.

By focusing on therapy, healthcare professionals aim to not only treat the underlying causes of diseases but also support the overall recovery and improvement in the quality of life for patients. This distinguishes it from other terms in the options, which pertain to different aspects of the healthcare process. For instance, diagnosis is the identification of a disease based on symptoms and tests, while intervention often refers to actions taken to improve a situation, which may or may not involve direct treatment. Assessment pertains to the evaluation of a patient’s condition to inform care decisions, rather than the treatment itself.
