Hippocampal dopamine D2 receptors correlate with memory functions in Alzheimers disease.

Post mortem studies have revealed a loss of dopamine D2 receptors in the temporal lobes in Alzheimers disease (AD). Moreover, the role of hippocampal D2 receptors on memory performance has been suggested in experimental studies. However, there are no ...

Implicit learning of visuospatial sequences in schizophrenia.

The authors examined whether patients with schizophrenia learned sequential patterns in a probabilistic serial response time task in which pattern trials alternated with random ones. Patients showed faster and more accurate responses to pattern trials ...

Quantitative EEG and dynamic susceptibility contrast MRI in Alzheimers disease: a correlative study.

OBJECTIVE: To investigate the relationship between the electroencephalographic (EEG) power spectra features obtained by quantitative EEG (qEEG) and the hemodynamic parameters detected by dynamic susceptibility contrast-enhanced MR imaging (DSC MRI) in ...

Effects of the use of alcohol and cigarettes on cognition in elderly African American adults.

In this study we examined the independent and interactive effects of lifetime patterns of drinking and smoking on cognitive performance in elderly African Americans. A sample of 230 individuals with varying histories of alcohol and cigarette use was ...

An open trial of bupropion for the treatment of adults with attention-deficit/hyperactivity disorder and bipolar disorder.

BACKGROUND: Despite the increasing recognition of comorbid attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder (BPD) in adults, there are no prospective trials of pharmacological agents to treat ADHD in these patients. Given the efficacy ...

Can adults with attention-deficit/hyperactivity disorder be distinguished from those with comorbid bipolar disorder? Findings from a sample of clinically referred adults.

BACKGROUND: Despite data describing the overlap of attention deficit hyperactivity disorder (ADHD) and bipolar disorder (BPD) in youth, little is known about adults with these co-occurring disorders. We now evaluate the clinical characteristics of ...

Monitoring sedation status over time in ICU patients: reliability and validity of the Richmond Agitation-Sedation Scale (RASS).

CONTEXT: Goal-directed delivery of sedative and analgesic medications is recommended as standard care in intensive care units (ICUs) because of the impact these medications have on ventilator weaning and ICU length of stay, but few of the available ...

A functional magnetic resonance imaging study of bipolar disorder: state- and trait-related dysfunction in ventral prefrontal cortices.

BACKGROUND: Abnormalities in prefrontal and anterior cingulate cortices are implicated in disturbances of attention, cognition, and impulse regulation in bipolar disorder. Acute episodes have been associated with dysfunction in these brain regions, and ...

Neuropsychological performance and regional cerebral blood flow in obsessive-compulsive disorder.

Convergent findings from neuropsychological and neuroimaging studies have suggested that neural dysfunction in frontal-subcortical circuits may play a central role in the pathophysiology of obsessive-compulsive disorder (OCD). To further examine the ...

Apathy and cognitive performance in older adults with depression.

OBJECTIVES: Recent studies have linked apathy to frontal lobe dysfunction in persons with dementia, but few studies have explored this relationship in older, depressed persons without dementia. We examined the association between apathy and cognitive ...
