Advancement in the field of science and technology has taken medicine to a whole new level. Today, specialization is the key to success which has broadly been accepted by all. Over the years, a number of different types of doctors have come up. This article talks about some of the prominent specializations in medicine.

Optometrist: This is the type of doctor to approach when suffering from problems related to the eye (the name is derived from the word "Optical"). They are experts in the field of eye disorders and are responsible for suggesting and prescribing treatment methods post carrying out various types of tests to determine the problem(s). A common instance when we come across them is at the time of getting lenses (it is they who decide the power and type of lenses required). At times, when the problem is pathologic in nature, they may refer the patient to an ophthalmologist who would then perform a surgery if required.

Psychiatrist: Psychiatrist as the name suggests deal with the psyche of their patients. They are the ones who specialize in treating people against non physical problems and include cases of mental, behavioral, and emotional problems. Depression and schizophrenic cases are run of the mill of them and they are experts in resolving them. Unlike other types of doctors who practice surgeries, psychiatrists indulge in therapy. Treatment is started only after a detailed study of their patient's behavior which is why all care is personalized and patient intensive. Different psychiatrists have different ways of undertaking this practice with only the ground rules been laid down by the books.

Neurologist: Neurologists work on the nervous system of their patients. This specialization deals with the nerves and the brain. It is a known fact that the human body is interconnected with each organ dependent on the functioning of other in some way or the other. As such, a complication in some part may cause severe damage to the nervous system. Neurologists are experts are diagnosing and treating such problems. Another reason why they are considered so highly is because these are the only type of doctors who have to know the complete functioning of the body in order to be successful.

Dermatologist: Dermatologists are doctors who are bestowed with the responsibility of taking care of skin problems including the likes of acne, skin cancer etc. They study the skin and its properties in detail which enables them to understand and analyze problems and what they might have resulted from. With people actively falling for plastic surgery, tattoos etc. the numbers of patients with skin complications and allergies are on the rise.

Nephrologists: These types of doctors treat disorders and problems related to the kidney. A reason why this specialization is important is because it is essential for the body to dispose harmful toxins for proper functioning. Treatment may be done by the use of medicines and if that fails, they may resort to removal of wastes with the help of equipments meant to do so popular amongst which is the dialysis machine. Cases involving removal or replacement of kidneys are also undertaken by the nephrologists.
