Abstract
Human immunodeficiency virus (HIV-1) infection and acquired immunodeficiency syndrome (AIDS) lead to neurocognitive disorders; however, there is still much knowledge to be gained regarding HIV-associated neurocognitive disorders. The purpose of this study was to assess the cognitive performance, instrumental activities of daily living, depression, and anxiety in patients with asymptomatic HIV-1 infections compared with seronegative participants without neurocognitive impairment. We studied a sample consisted of 60 patients with asymptomatic HIV-1 infections and 60 seronegative participants without neurocognitive impairment from the city of Barranquilla, Colombia, with a mean age of 36.07 years. A protocol of neuropsychological and psychopathological tests was applied to the participants. The group of patients with asymptomatic HIV infections significantly underperformed on tasks that assessed global cognitive screening, attention span, learning, phonemic verbal fluency, auditory-verbal comprehension, information processing speed, cognitive flexibility, and motor skills compared to the group of seronegative participants. No significant differences were found in memory, visual confrontation naming, vocabulary, inhibition, and instrumental activities of daily living. Additionally, the patients with asymptomatic HIV-1 infection had a higher anxiety index than the seronegative participants, but no significant difference was found in depression. A correlation was found between depression and anxiety. In conclusion, the patients with asymptomatic HIV-1 infection had lower cognitive performances than the seronegative participants in the cognitive functions mentioned above and more anxiety but still performed the instrumental activities of daily living.

Abstract
PURPOSE To use the World Health Organization's International Classification of Functioning, Disability and Health (ICF) to explore the experiences of women living with self-identified HIV-associated neurocognitive challenges. METHOD This interpretive, qualitative study involved key informant interviews with 16 women with self-identified HIV-associated neurocognitive challenges. Data were collected through 60-90 min, in-depth, semi-structured interviews. Thematic analysis was performed using an inductive approach. Theoretical analysis then used the ICF to reconceptualize the data using a disability lens. RESULTS Participants perceived impairments (e.g. memory loss, difficulty multi-tasking) and participation restrictions (e.g. parenting, work roles) resulting from their neurocognitive challenges as having a larger impact on their daily lives than activity limitations (e.g. difficulty with chores). Participants held contrasting views about parenting: women with children drew strength from parenting whereas women without children worried that parenting could compromise their health. Participation in work and volunteering roles was viewed as integral to managing neurocognitive challenges and health overall. CONCLUSIONS Conceptualizing neurocognitive challenges through a disability lens focuses attention on how impairments interact with other realities in these women's lives. This exploratory study reveals the need for future research exploring perceptions among people living with HIV-associated neurocognitive challenges with attention to aging and among other vulnerable groups.

Abstract
Episodic memory deficits are common in HIV infection and bipolar disorder, but patient insight into such deficits remains unclear. Thirty-four HIV-infected individuals without bipolar disorder (HIV+/BD-) and 47 HIV+ individuals with comorbid bipolar disorder (HIV+/BD+) were administered the Hopkins Verbal Learning Test-Revised and the Brief Visuospatial Memory Test-Revised to examine objective learning/memory functioning. Subjective memory complaints were assessed via the memory subscale of the Patient's Assessment of Own Functioning Inventory. HIV+/BD+ individuals performed poorer on tests of visual learning and visual/verbal recall than did HIV+/BD- participants (ps < .05). Memory complaints only predicted verbal learning (at a trend level, p = .10) and recall (p = .03) among the HIV+/BD- individuals. Memory complaints were not associated with memory performance within the HIV+/BD+ group (ps > .10). Memory complaints were associated with depressive symptoms in both groups (ps < 0.05). These complaints were also predictive of immunosuppression, higher unemployment, and greater dependence on activities of daily living among the HIV+/BD+ individuals (ps < .05). Awareness of memory abilities was particularly poor among HIV+/BD+ individuals (i.e., objective learning/memory did not correspond to reported complaints), which has important implications for the capacity of these individuals to engage in error-monitoring and compensatory strategies in daily life. Memory complaints are associated with depressed mood regardless of group membership. Among HIV+/BD+ individuals, these complaints may also signify worse HIV disease status and problems with everyday functioning. Clinicians and researchers should be cognizant of what these complaints indicate in order to lead treatment most effectively; use of objective neurocognitive assessments may still be warranted when working with these populations.

Abstract
As many as 50% of people living with HIV/AIDS report cognitive difficulties, which can be associated with objective neuropsychological impairments and depression. A number of studies have demonstrated an association between higher social support and lower rates of depression. Using a cross-sectional design, we examined the role social support may play in attenuating the effects of both neuropsychological status and depression on cognitive difficulties. A total of 357 participants completed a battery of neuropsychological tests, questionnaires about cognitive difficulties and depression, and an interview that included an assessment of perceived level of social support. A multivariate linear regression analysis revealed that higher levels of cognitive symptom burden were significantly associated with depression (P<0.05) while lower levels of cognitive symptom burden were significantly associated with greater social support (P<0.01) and higher level of education (P<0.05). There was a significant interaction between neuropsychological status and depression (P<0.001); the presence of neuropsychological impairment with depression was associated with higher levels of cognitive symptom burden. There was also a significant interaction between social support and depression (P<0.05). Interestingly, social support was also associated with a lower cognitive symptom burden for non-depressed individuals living with HIV/AIDS. These findings have important clinical implications for promoting psychological well-being in persons living with HIV/AIDS. To improve quality of life, it is important to screen for and identify individuals with HIV/AIDS who may be depressed and to intervene appropriately. Further research should examine the potential role of social support interventions in modifying the effects of both depression and neuropsychological status on cognitive symptom burden.

Abstract
OBJECTIVE The risks and factors contributing to major depressive episodes in HIV infection remain unclear. This 2-year prospective study compared cumulative rates and predictors of a major depressive episode in HIV-infected (HIV+) men (N=297) and uninfected (HIV-) risk-group controls (N=90). METHODS By design participants at entry were without current major depression, substance dependence or major anxiety disorder. Standardized neuromedical, neuropsychological, neuroimaging, life events, and psychiatric assessments (Structured Clinical Interview for DSM III-R) were conducted semi-annually for those with AIDS, and annually for all others. RESULTS Lifetime prevalence of major depression or other psychiatric disorder did not differ at baseline between HIV+ men and controls. On a two-year follow-up those with symptomatic HIV disease were significantly more likely to experience a major depressive episode than were asymptomatic HIV+ individuals and HIV-controls (p<0.05). Episodes were as likely to be first onset as recurrent depression. After baseline disease stage and medical variables associated with HIV infection were controlled, a lifetime history of major depression, or of lifetime psychiatric comorbidity (two or more psychiatric disorders), predicted subsequent major depressive episode (p<0.05). Neither HIV disease progression during follow-up, nor the baseline presence of neurocognitive impairment, clinical brain imaging abnormality, or marked life adversity predicted a later major depressive episode. LIMITATIONS Research cohort of men examined before era of widespread use of advanced anti-HIV therapies. CONCLUSIONS Symptomatic HIV disease, but not HIV infection itself, increases intermediate-term risk of major depression. Prior psychiatric history most strongly predicted future vulnerability.

Abstract
Diagnosis of neurobehavioral syndromes associated with HIV infection requires the determination that neuropsychological (NP) deficits are present, are not caused by any comorbid (e.g., psychiatric) condition, and significantly affect everyday functioning. Methamphetamine (Meth) dependence and depression are common comorbid conditions with HIV and may complicate diagnosis of HIV-associated neurobehavioral syndromes. The current study examined the complex relationships between depression and NP impairment, and self-report of problems with everyday functioning, in 362 adults with HIV infection or Meth dependence, or both. Everyday functioning was measured with questionnaires of instrumental activities of daily living (IADLs) and reported cognitive difficulties. Results indicate that comorbid HIV and Meth did not increase the likelihood of complaints regarding everyday functioning, beyond what was seen with either single risk factor. Across all groups, depressive symptoms predicted greater IADL decline and cognitive complaints, while NP impairment predicted cognitive complaints more than IADL decline. Both IADL decline and cognitive complaints were associated with higher rates of unemployment and worse clinician ratings of overall functioning (Karnofsky ratings), even when depressive symptoms were controlled. These results suggest that depressive symptoms should not be used to dismiss subjective complaints related to everyday functioning even though depressive symptoms account for significant variance in self-reported complaints. Additional research is needed to clarify the potentially reciprocal causal relationships between depressive symptoms and impairment in everyday functioning.

Abstract
The main objective of this study was to use structural equation modeling (SEM) to clarify the relationship between subjective cognitive complaints and neuropsychological functioning in 160 adults with HIV infection. Participants completed questionnaires assessing cognitive complaints, symptoms of depression, and HIV-related medical symptoms. Neuropsychological tests included measures of attention, verbal fluency, psychomotor skills, learning, memory, and executive skills. SEM was used to test models of the relationships among cognitive complaints, mood, and medical symptoms with neuropsychological functioning. The model indicated that although depressed mood (beta = 0.32, p < .01) and medical symptoms (beta = 0.31, p < .01) influenced cognitive complaints, cognitive complaints were independently associated with poorer neuropsychological performance (beta = 0.39, p < .01). Mood and medical symptoms were significantly correlated but were not significantly associated with neuropsychological skills.

Abstract
To investigate the association of antigen specific CD4 T cell activation with HIV disease progression and AIDS-related central nervous system damage, T cell proliferation responses to HIV, CMV, and HSV were evaluated in infected individuals. CD4 T cell loss and neurocognitive impairment were assessed at 6-mo intervals. Individuals with known times of seroconversion who responded to more HIV peptides were at greater risk of progressing to < 200 CD4 T cells (P = 0.04) and dying (P = 0.03) than those with responses to fewer peptides. A positive correlation (0.52) was seen between the breadth of the HIV proliferation response and HIV plasma RNA levels. Higher proliferation responses to CMV and HSV were also associated with more rapid CD4 loss (P = 0.05). HLA phenotyped individuals (n = 150) with two HLA-DR alleles associated with response to more HIV peptides and CMV (DR-2,5,w6,10) were less likely to develop neurocognitive (P = 0.002) and neurologic impairment (P = 0.04), but were not protected from CD4 loss and death. Thus, the ability to generate a greater T cell proliferation response to HIV and opportunistic herpes viruses may lead to resistance to central nervous system damage, but also risk of more rapid HIV disease progression.
