This article presents a literature review and description of seasonal affective disorder (SAD). SAD is a newly recognized disorder, differentiated from other affective illnesses by its seasonality (with midwinter dysthymia and spring/summer remission), and its atypical symptoms of hypersomnia and hyperphagia. SAD symptoms remit with travel towards the equator or with bright light treatments, possibly indicating a chronobiological circadian etiology. This article introduces aspects of SAD that are amenable to the nursing process, including assessment of the seasonality of dysthymic symptoms; diagnoses of patient responses; referral, education, and psychotherapeutic interventions; and evaluation of patient responses to interventions. Since SAD is found predominantly in young women, and because symptoms may be exacerbated by rotating shifts, it is possible that nurses may have a higher incidence of SAD, compared with other professions.

Dysthymic disorder, a chronic disturbance of mood, manifests as depressed mood for most of the day, more days than not, for at least two years. In children, dysthymia may present as irritable mood, and a duration of symptoms of only one year is required to make the diagnosis. By definition, there is no history of a major depressive disorder. Associated symptoms include poor appetite or overeating, insomnia or hypersomnia, poor concentration or difficulty making decisions, low energy, low self-esteem and feelings of hopelessness. Because of the chronic nature of this disorder, treatment requires an understanding approach and continuity of care.

Patients meeting criteria for borderline personality disorder are heterogeneous. Our studies suggest that at least two sub-types exist which benefit from specific treatments. Data will be presented which suggests that some patients who meet borderline criteria and have atypical depression (patients meeting DSM III-R criteria for major depression or dysthymia reactive wills mood and any vegetative atypical symptoms, i.e. overeating, oversleeping, rejection sensitivity, leaden paralysis) clearly benefit from treatment with antidepressant medication. Although some patients with atypical depression who meet borderline criteria will improve with tricyclic therapy, a significantly greater proportion will improve with the monoamine oxidase inhibitor (MAOI) phenelzine if they suffer from atypical depression. The validity of emotionally unstable character disorder (EUCD) will also be examined. Patients with this disorder frequently meet criteria for borderline character disorder. The validity of this sub-group is supported by the presence of neurological soft signs, their negative response to anti-depressants, and their positive response to chlorpromazine and lithium.

Depression with atypical features is a treatable and relatively common disorder among depressed outpatients. A growing body of evidence suggests this is a biologically distinct subtype of depression. This assertion is supported by genetic epidemiologic studies and by a preferential response of the subtype to monoamine oxidase inhibitors compared with tricyclic antidepressants. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) includes atypical features as a parenthetical modifier for depressive illness. According to DSM-IV diagnostic criteria ("atypical features" specifier), the disorder is primarily characterized by 2 or more of the following symptoms as predominant features in patients with major depression or dysthymic disorder: overeating, oversleeping, "leaden paralysis," and interpersonal rejection sensitivity. Patients also show mood reactivity in response to actual or potential positive events. Despite aspects of the disorder resembling a maladaptive, persistent mode of behavior, patients diagnosed with depression with atypical features demonstrate a good response to antidepressant treatment.
