A retrospective review of the records of 755 patients seen by a psychiatric consultation-liaison service in a general hospital was performed. The authors found that 87% of manic patients and 38% of depressed patients had a diagnosis of organic mood disorder. The most frequent precipitants of mania were corticosteroids, human immunodeficiency virus (HIV) infection, and temporolimbic epilepsy. The most frequent precipitants of depression were stroke, Parkinson's disease, and HIV infection.

HIV disease often leads to neuropsychiatric disturbance, either through direct infection of the brain by the virus or through CNS disease secondary to immunodeficiency. Neuropsychiatric complications of AIDS and AIDS-related disorders may present clinically as acute or chronic organic mental syndromes, or may mimic functional psychiatric illness, in particular depression, anxiety, or psychotic states. Two cases of hypomanic states in homosexual men suffering from AIDS are reported. Neither of the two men had a personal or family history of affective disorder. In one man, hypomanic symptoms were caused by early HIV encephalopathy; he rapidly developed typical HIV dementia with a marked downhill course. In the second case, a clear connection between the hypomanic symptoms and direct HIV brain involvement was not established.

The present study determined lifetime and current psychiatric functioning in a sample of homosexual or bisexual men at various stages of human immunodeficiency virus (HIV) infection in order to address several questions regarding the relationship between psychopathology and HIV infection. HIV+ asymptomatic or symptomatic and HIV- homosexual or bisexual men completed self-report measures of psychological and health functioning and participated in structured diagnostic interviews. Additional information regarding HIV-related life events and their potential relationship to onset of disorder and family history of psychiatric disorder were obtained. A high lifetime prevalence of affective and substance use disorder was found, with almost one half of the sample meeting criteria for both disorders. Lifetime affective disorder diagnosis was associated with a positive family history of affective disorder. HIV-related events were most closely associated with onset or recurrence of affective disorder compared with other disorders. Low current rates of psychiatric disorder and levels of emotional distress were found, with no differences in degree of psychiatric adjustment across stage of infection. We conclude that the lifetime prevalence of certain categories of psychiatric disorder is high in both HIV+ and HIV- homosexual samples. Increased rates of psychiatric disorders do not appear to be a consequence of HIV infection. However, episodes of illness, particularly affective disorder, may develop following an HIV-related event such as confirmation of infection. Although symptomatic subjects have more somatic difficulties, there appears to be no relationship between stage of illness and level of emotional distress.

This report presents systematic clinical data regarding psychiatric diagnoses, personal and family psychiatric histories, and symptomatologic aspects of 90 consecutive human immunodeficiency virus (HIV)-seropositive and acquired immune deficiency syndrome (AIDS) patients, of whom slightly less than two thirds were at risk due to intravenous drug abuse. In addition, a comparison was made between the distribution patterns of these variables at various stages of HIV illness and related at-risk behaviors. Eighty-four percent of the patients met criteria for a spectrum of DSM-III-R diagnoses (mostly affective) that were associated with high rates of affective and alcohol abuse disorders among first-degree relatives. Mood disorders did not differ significantly between the two main groups at risk (intravenous drug users [IVDUs] v others) by gender, age, or stage of illness. The overall data from the rating scales show high levels of psychic and somatic anxiety in the early stages of illness, whereas cognitive symptoms, retardation, and disorientation are dominant in later stages. A noteworthy finding in this study is that many depressed patients demonstrated current and/or past hypomanic, hyperthymic, or cyclothymic features with no evidence of brain damage detectable by computed axial tomography (CAT). These temperamental attributes, which preceded HIV infection, may have served as risk factors for both drug abuse and impulsive sexual behavior in all types of at-risk groups.

We examined the relationship between coping responses and mood states among three samples of patients with human immunodeficiency virus (HIV) infection (n=26), end-stage renal failure (n=98), and breast cancer (n= 60). Avoidance scores differed significantly across the groups, being highest in those with HIV infection. The avoidance scores were significantly and positively correlated with depression scores. However, patients with HIV infection did not fulfill the diagnostic criteria for major depression. Although patients with HIV infection may have minor psychiatric symptoms, results suggest that the symptoms are not strong enough to warrant a psychiatric diagnosis of mood disorder. It might be clinically important to attend to avoidance behaviors and thoughts which may develop into the manifestation of depression.

The potential for secondary (biological or psychological) mood disorders would seem to be heightened in human immunodeficiency virus (HIV) for many reasons. HIV infection is associated with lethal, multisystem illness related to profound immune dysregulation; infection involves the central nervous system (CNS) shortly after infection and leads to substantial neurocognitive impairment even in the absence of other physical evidence of disease. Psychological forces at work include social stigimitization of unparalleled proportion for the modern era, combined with bereavements of epidemic proportions, Nevertheless, it is misleading to attribute to HIV itself-or to its psychological and social consequences-all episodes of mood disorder. Preinfection rates of major depression are high in groups at greatest risk for HIV. Rates of "current" major depression approach 10%, but perhaps 50% of affected individuals have preinfection evidence of mood disorder. Mania is relatively rare, with an overall prevalence less that 1%. "Subsyndromic" mood disorder is understudied, but may effect an important minority of individuals. Given current advances in neuromedical evaluation, neuropsychological assessment, and rigorous psychiatric criteria, it is likely that study of secondary mood disorders in HIV can contribute to important advances in our understanding of brain-behavioral relationships.

Prominent apathy and/or irritability are frequently observed among individuals infected with the human immunodeficiency virus (HIV). Although these symptoms often occur as part of a mood disorder, compelling evidence suggests that they may occur independently of depression in neurologic disease/disorder. The current study examined the prevalence of both apathy and irritability among a sample of HIV-infected individuals and explored the degree to which these neuropsychiatric (NP) phenomena were associated with performance on neuro-cognitive measures thought to be sensitive to the potential CNS effects of HIV-1. Clinician-administered rating scales assessing apathy and irritability were administered to 65 HIV-seropositive (HIV+) and 21 HIV-seronegative (HIV-) participants who also completed a dual-task reaction time paradigm and the Stroop task. NP disturbance was significantly more prevalent among HIV+ participants compared with HIV- controls and was associated with specific neuro-cognitive deficits suggestive of executive dysfunction. Relative to both HIV- controls and to neuro-psychiatrically intact HIV+ participants, those HIV+ individuals with evidence of prominent apathy and/or irritability showed deficits in dual-task, but not single-task, performance and on the interference condition of the Stroop. Unexpectedly, NP disturbance did not show a robust relationship with HIV disease stage. These results suggest that the presence of prominent apathy and/or irritability among HIV+ individuals may signify greater HIV-associated CNS involvement. In HIV/AIDS, the disruption of frontal-subcortical circuits may be a common mechanism causing both executive dysfunction and NP disturbance.

People living with a mental illness are disproportionately vulnerable to human immunodeficiency virus. The current study sought to examine the influence of psychiatric disorder, substance use disorder, and gender on risky sexual behavior in this vulnerable population. Participants were 228 female and 202 male outpatients (66% mood disorder, 34% schizophrenia), each of whom took part in a Structured Clinical Interview for the DSM-IV and a comprehensive assessment of sexual risk behavior. Univariate and multivariate analyses tested a priori hypotheses. The results indicated that risk behavior was more frequent among patients diagnosed with a mood disorder (compared with those diagnosed with schizophrenia) or a substance use disorder (compared with those without a comorbid disorder) or both. We recommend routine human immunodeficiency virus risk screening and risk reduction programs for this vulnerable population.

Mood disorders are common mental illnesses. Among the factors associated with major depression are exposures to infectious diseases including hepatitis C, influenza, varicella-zoster, and herpes viruses. In this study, we sought to evaluate further associations between viral exposure and depression. From the US Center for Disease Control's National Health and Nutrition Examination Survey, we obtained data about depression status, antidepressant use, exposure to hepatitis A, hepatitis B, herpes simplex virus type 1, herpes simplex virus type 2, human immunodeficiency virus, and cytomegalovirus, and sociodemographic variables and evaluated associations between depression and viral exposure in adjusted multivariable models. Herpes simplex virus type 2 was associated with an increased risk of depression, whereas hepatitis A, hepatitis B, and herpes simplex virus type 1 were not. Higher cytomegalovirus antibody levels were associated with depression in subjects seropositive for cytomegalovirus. In conclusion, exposure to herpes simplex virus type 2 and possibly cytomegalovirus are associated with depression in an adult US sample.
