Depression, dysthymia
A type of depression involving long-term, chronic symptoms that are not disabling, but keep a person from functioning at "full steam" or from feeling good. Dysthymia is a less severe type of depression than what is accorded the diagnosis of major depression. However, people with dysthymia may also sometimes experience major depressive episodes, suggesting that there is a continuum between dysthymia and major depression.
Depression, major

PREVIOUS AND NEXT TERMS--------------------------------------
Dehdroepiandrosterone (DHEA)
A steroid hormone produced in the adrenal glands. Its primary function is to inhibit the binding of cortisol.
Diabetes
A condition in which blood glucose is not well controlled. Type I diabetics make no insulin, whereas type 2 diabetics are characterized by the overproduction of insulin, but the inability of the target cells to respond to the insulin.
Dopamine
A neurotransmitter that works in an axis with serotonin.
Dermatitis
Dermatitis, also known as eczema, is a skin irritation characterized by red, flaky skin, sometimes with cracks or tiny blisters. Dermatitis is extremely itchy, but scratching damages the fragile skin and exacerbates the problem so it is important for people with eczema to try to leave the area alone.
Dominant gene
A gene which, when present on a chromosome, passes on a certain physical characteristic, even when the gene is present in only one copy. A dominant disorder can be inherited from only one parent.
Depression
Diabetes Mellitus
A metabolic disease caused by an absolute or a relative deficiency of insulin, a hormone that controls how the body processes glucose, protein, and fats. When the body's insulin supply is decreased, it cannot process carbohydrates and it compensates by overprocessing fats and protein. The condition is characterized by chronic high blood sugar and sugar in the urine. Diabetes mellitus can result in coma. Over time, complications can include nerve injury, blindness, kidney failure, and premature atherosclerosis with all of its complications.
Diabetic Retinopathy
Severe changes in the back of the eye, or the retina, caused by diabetes. These may include ongoing microaneurysms, retinal hemorrhages or swelling in the central part of the eye (macula). The proliferative type involves the growth of abnormal blood vessels in the retina or at the optic disc with blood leaking into the jelly part of the eye (vitreous), or a detachment of the retina.
Diplopia
Diplopia is a visual disorder that results in double vision, such that when the viewer looks at an object it seems as if there are two objects. It can arise when the eye muscles are not functioning as intended, and the eyes are not correctly aligned while focusing on an object. This binocular diplopia disappears when one eye is closed.
Dyscalculia
Is a term used to refer to learning disabilities that involve arithmetic comprehension or computation. This difficulty in mastering concepts or computations is usually associated with neurological dysfunction or brain damage and is classified as developmental (occurring before birth from genetic or congenital problems) or acquired (occurring after birth usually from a traumatic brain injury).
Dysgraphia
Dysgraphia is the inability to write, regardless of ability to read. People with dysgraphia often can write, but lack co-ordination, and find other fine motor tasks like tying shoes difficult. They also lack basic spelling skills, and often will say the wrong word when trying to formulate thoughts.
