Depression:
Medical causes
(Handbook of Signs & Symptoms (Third Edition))
Organic disorders
Various organic disorders and chronic illnesses produce mild, moderate, or severe depression. Among these are metabolic and endocrine disorders,such as hypothyroidism, hyperthyroidism, and diabetes; infectious diseases, such as influenza, hepatitis, and encephalitis; degenerative diseases, such as Alzheimer's disease, multiple sclerosis, and multi-infarct dementia; and neoplastic disorderssuch as cancer.Psychiatric disorders
Affective disordersare typically characterized by abrupt mood swings from depression to elation (mania) or by prolonged episodes of either mood. In fact, severe depression may last for weeks. More moderate depression occurs in cyclothymic disordersand usually alternates with moderate mania. Moderate depression that's more or less constant over a 2-year period typically results from dysthymic disorders. Also, chronic anxiety disorders,such as panic and obsessive-compulsive disorder, may be accompanied by depression.Other causes
Alcohol abuse
Long-term alcohol use, intoxication, or withdrawal commonly produces depression.Drugs.
Various drugs cause depression as an adverse effect. Among the more common are barbiturates; chemotherapeutic drugs, such as asparaginase; anticonvulsants, such as diazepam; and antiarrhythmics, such as disopyramide. Other depression-inducing drugs include centrally acting antihypertensives, such as reserpine (common in high dosages), methyldopa, and clonidine; beta-adrenergic blockers, such as propranolol; levodopa; indomethacin; cycloserine; corticosteroids; and hormonal contraceptives.Postpartum period.
Although the cause hasn't been proved, depression occurs in about 1 in every 2,000 to 3,000 pregnancies and is characterized by various symptoms. Symptoms range from mild postpartum blues to an intense, suicidal, depressive psychosis.Source: Handbook of Signs & Symptoms (Third Edition), 2006
Fontanel depression:
Medical causes
(Handbook of Signs & Symptoms (Third Edition))
Dehydration
With mild dehydration (5% weight loss), the anterior fontanel appears slightly depressed. The infant has pale, dry skin and mucous membranes; decreased urine output; a normal or slightly elevated pulse rate; and, possibly, irritability
Moderate dehydration (10% weight loss) causes slightly more pronounced fontanel depression, along with gray skin with poor turgor, dry mucous membranes, decreased tears, and decreased urine output. The infant has normal or decreased blood pressure, an increased pulse rate and, possibly, lethargy.
Severe dehydration (15%or greater weight loss) may result in a markedly sunken fontanel, along with extremely poor skin turgor, parched mucous membranes, marked oliguria or anuria, lethargy, and signs of shock, such as a rapid, thready pulse; very low blood pressure; and obtundation.

Major depression:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The multiple causes of depression aren’t completely understood. Current research suggests possible genetic, familial, biochemical, physical, psychological, and social causes. Psychological causes (the focus of many nursing interventions) may include feelings of helplessness and vulnerability, anger, hopelessness and pessimism, and low self-esteem. They may be related to abnormal character and behavior patterns and troubled personal relationships. In many cases, the history identifies a specific personal loss or severe stressor that probably interacts with the person’s predisposition to provoke major depression.
Depression may be secondary to a specific medical condition — for example, metabolic disturbances, such as hypoxia and hypercalcemia; endocrine disorders, such as diabetes and Cushing’s syndrome; neurologic diseases, such as Parkinson’s and Alzheimer’s diseases; cancer (especially of the pancreas); viral and bacterial infections, such as influenza and pneumonia; cardiovascular disorders, such as heart failure; pulmonary disorders, such as chronic obstructive lung disease; musculoskeletal disorders, such as degenerative arthritis; GI disorders, such as irritable bowel syndrome; genitourinary problems, such as incontinence; collagen vascular diseases, such as lupus; and anemias.
Drugs prescribed for medical and psychiatric conditions as well as many commonly abused substances can also cause depression. Examples include antihypertensives, psychotropics, opioid and nonopioid analgesics, antiparkinsonian drugs, numerous cardiovascular medications, oral antidiabetics, antimicrobials, steroids, chemotherapeutic agents, cimetidine, and alcohol. Depression occurs in up to 18 million Americans, affecting all racial, ethnic, and socioeconomic groups. It affects both sexes, but is more common in women.
