The history of the term "empathy" (translated from the German word Einfuhlung, that means feeling into) started over 100 years ago, introduced by the psychologist Edward Titchener.
Empathy is a complex psychological influencing social interaction; it plays a role in the understanding of other's feelings, suffering, and behavior with a significant link to compassion. It is a motivated phenomenon that allows people to connect emotionally, mainly by sharing experiences and feelings.
Empathy has been shown to be linked to neuroanatomical structures such as the amygdala, anterior cingulate cortex, and anterior insula. Furthermore, a multidimensional approach to empathy classifies it as either being cognitive, affective, or behavioral empathy. 
In order to measure empathy, several scales have been designed that help to identify the capacity of an individual to be more empathic or less empathic. As empathy involves a wide range of psychological concepts, many scales are currently being used to identify empathy. Some of these include the Empathic Accuracy Task (EAT), Empathy Components Questionnaire, and the very old Interpersonal Reactivity Index (IRI). 
Influence of Empathy on the healthcare team and delivery
A healthcare professional has to bring empathy to the table when they are dealing with a patient as it helps them to comprehend the emotional and the cognitive state of the patient involved. This connection can help healthcare professionals to build a therapeutic relationship with the patients that can eventually lead to better health outcomes. This influence is not only determined by the words chosen but also by facial expressions, body language, and vocalization. The emotional and cognitive connection is invaluable in the current day healthcare delivery to achieve the best patient-provider relationship.
As empathetic behavior by providers gets modulated by motivation, health care providers should also have empathic support from their institutions to deliver the same high-quality care for the patients.
Clinical significance of empathy:
Increasing empathy in the practice:
Cognitive empathy modulated by motivation can help to make better providers. There are many motivational triggers to increase empathy; those strategies apply to the interprofessional team and patient's care and is achievable by regular and thoughtful training.
These kinds of modulation can increase patient satisfaction and improve the diagnostic process and treatment outcome.
Disorders of Empathy
Disturbance in an appropriate empathic/vicarious response can be associated with some conditions such as:
Education and training by various seminars showed to be effective in training medical students for empathic communication; therefore, training of health care professionals is essential to prepare them for excellent patient care.
Empathy for nursing is describable as both a human trait and a professional state. Empathy plays a vital role in decision making to deliver patient-centered care.
Understanding and Educating
As empathic responses may be dysfunctional in patients with Alzheimer's disease and frontotemporal dementia, the professional that deals with these patients need to be trained/educated to understand empathic behavior and deliver proper care for these specific cases.
