4. Introduction
Depression
 or depressive disorders (unipolar depression
) are mental
 illnesses characterized by a profound and
persistent feeling
 of sadness or despair
and/or
 a loss of interest in things that once were
pleasurable.
 Disturbance in sleep,appetite, and mental
processes
 are a common accompaniment.

5. Introduction (cont.)
Depression is the oldest and most frequently
described psychiatric illness.
Transient symptoms are normal, healthy
responses to everyday disappointments in life.
Pathological depression occurs when
adaptation is ineffective.

6. Epidemiology
Gender prevalence
Higher in women than in men by about 2 to 1
Age
Depression more common in young women
than in older women
Opposite is true for men
Marital status: Single and divorced people
more likely to experience depression than
married people

7. Epidemiology (cont.)
Social class: There is an inverse
relationship between social class and
report of depressive symptoms; the
opposite is true with bipolar disorder.
Seasonality: Affective disorders are
more prevalent in the spring and in the
fall.

and subside shortly after onset of menstruation

12. Etiological Implications-Depressive
Disorders
Biological theories

part of clinical picture

Medications: pretreatment medication; muscle relaxant;
short-acting anesthetic

of married people

five times greater than those who are married
Gender: Women attempt suicide more often; more men
succeed
Age: Suicide highest in persons older than 50 years;
adolescents also at high risk

41. Nursing Process: Suicide Assessment (cont.)

lowest social classes have higher suicide rates than
those in the middle classes.

and business executives are at the highest risk.
Religion

42. Nursing Process: Suicide Assessment
(cont.)

psychiatric diagnosis
