Spontaneous intrusive recollections (SIRs) are known to follow emotional events in clinical and non-clinical populations. Previous work in our lab has found that women report more SIRs than men after exposure to emotional films, and that this effect is driven entirely by women in the luteal phase of the menstrual cycle. To replicate and extend this finding,(More)
There has been a reduction in the most severe cases of HIV-associated neurocognitive disorders (HAND) with advances in antiretroviral treatment (ART). But the prevalence of milder forms of HAND still remains high. Data from systematically conducted studies on the effects of ART on cognition are scanty in India, where HIV-1 clade C is prevalent. The purpose(More)
Apathy is a relatively common psychiatric syndrome in HIV infection, but little is known about its neural correlates. In the present study, we examined the associations between apathy and diffusion tensor imaging (DTI) indices in key frontal white matter regions in the thalamocorticostriatal circuit, which has been implicated in the expression of apathy.(More)
BACKGROUND Brazil accounts for the largest number of HIV+ persons in Latin America, and this epidemic poses a significant public health burden in this country. Little is known about the neuropsychiatric and functional consequences of HIV infection in this population. METHODS Participants were 43 HIV+ and 29 HIV- individuals who underwent a(More)
PURPOSE: Patients with obstructive sleep apnea (OSA) commonly have cognitive complaints. There are few randomized studies that have examined neuropsychological effects of continuous positive airway pressure (CPAP) treatment in patients with OSA. In this double-blind trial, we examined if a 3-week CPAP treatment compared with placebo CPAP treatment has(More)
Apathy is a relatively common clinical feature of HIV-Associated Neurocognitive Disorders, but little is known about its implications for everyday functioning outcomes. In the present study, we examined the associations between apathy and self-reported instrumental activities of daily living (IADL) and neurocognitive complaints in 75 participants with HIV(More)
Apathy and depression are inter-related yet separable and prevalent neuropsychiatric disturbances in persons infected with HIV. In the present study of 225 HIV+ persons, we investigated the role of an incident depressive episode in changes in apathy. Participants completed the apathy subscale of the Frontal Systems Behavior Scale during a detailed(More)
BACKGROUND Obstructive sleep apnea (OSA) is a prevalent disorder with multiple consequences including negative effects on neurocognitive function. Several domains of cognitive function are impaired in OSA patients, but the mechanisms through which this sleep disorder results in impairment are not clear. Given the well-known effects of cortisol on cognitive(More)
The present study aimed to examine if bilingualism affects executive functions and verbal fluency in Marathi and Hindi, two major languages in India, with a considerable cognate (e.g., activity is actividad in Spanish) overlap. A total of 174 native Marathi speakers from Pune, India, with varying levels of Hindi proficiency were administered tests of(More)
BACKGROUND AND OBJECTIVE Acute and early human immunodeficiency virus infection (AEH) is accompanied by neuroinflammatory processes as well as impairment in neurocognitive and everyday functions, but little is known about the frequency and clinical correlates of the neurobehavioral disturbances during this period. We compared pre-seroconversion with current(More)
