Providing long-term care for a demented relative profoundly affects caregivers' lives. We assessed changes in depression, immune function, and health in 69 spousal caregivers who had already been caregiving for an average of five years and 69 sociodemographically matched control subjects. Between the initial sample ("intake") and the follow-up data collected an average of 13 months later, caregivers showed decrements relative to controls on three measures of cellular immunity. Caregivers also reported significantly more days of infectious illness, primarily upper respiratory tract infections. Caregivers had a much greater incidence of depressive disorders than controls, with 25% of caregivers meeting syndromal criteria at intake and 32% at follow-up, compared with no cases among controls at intake and 6% at follow-up. Caregivers who reported lower levels of social support at intake and who were most distressed by dementia-related behaviors showed the greatest and most uniformly negative changes in immune function at follow-up.

Current and lifetime rates of disorders outlined in the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev., DSM-III-R) were compared in 78 adult children caring for a parent with a progressive dementia and 78 control subjects. The frequencies of depressive and anxiety disorders did not differ between groups in the years prior to caregiving, and there were no differences between groups in first-degree relatives' incidence of psychiatric disorder. During the years they had been providing care, 34% ofcaregivers met DSM-III-R criteria: 24% for a depressive disorder and 10% for an anxiety disorder. In contrast, 8% of the matched controls met criteria during the same time period for depressive or anxiety disorders. Results support the chronic strains ofcaregiving being linked to the onset of both depressive and anxiety disorders in adult children caring for a demented parent.

Multiple aspects of family functioning were assessed when mothers experienced either chronic pain, a chronic illness (diabetes), or no illness. Mothers' and fathers' self-report measures of depression, anxiety, and family environment were collected. Children's self-report measures of depression and anxiety, as well as information about their overall adjustment, were collected. Family communication patterns were also assessed. Families with a mother who had chronic pain had poorer perceived family environments and higher levels of depression and anxiety compared to the other two groups of families. Children from chronic pain families also appeared to be adversely affected. The data suggest that level of disability appeared more salient than the type of chronic illness. Implications of the findings are discussed in light of the fact that mothers with chronic pain in the present sample reported relatively mild disability and were not actively seeking treatment for their condition.

Current and lifetime rates of Diagnostic and Statistical Manual (rev. 3rd ed.) disorders were compared in 86 older adults caring for a spouse with a progressive dementia and 86 sociodemographically matched control subjects. Dementia caregivers were significantly more dysphorie than noncare givers. The frequencies of depressive disorders did not differ between groups in the years before care giving, and there were no group differences in first-degree relatives' incidence of psychiatric disorder. During the years they had been providing care, 30% of care givers experienced a depressive disorder (major depression, dysthymia, or depression not otherwise specified) versus 1% of their matched controls in the same time period. Only two care givers who met criteria during care giving had met criteria for a depressive disorder before care giving, and family history was not even weakly related to the identification of at-risk care givers. In contrast to these group differences in depressive disorders, there were no significant differences in other Axis I disorders either before or during care giving. Thus, the chronic strains of care giving appear to be linked to the onset of depressive disorders in older adults with no prior evidence of vulnerability.
