Toward a neuropsychological theory of antidepressant drug action: increase in positive emotional bias after potentiation of norepinephrine activity.

OBJECTIVE: Antidepressants that increase serotonin or norepinephrine in the brain are effective in treating depression, but there is no neuropsychological account of how these changes relieve depressive states. Cognitive theories suggest that biases in ...

Functional disconnection between the prefrontal and parietal cortices during working memory processing in schizophrenia: a[15(O)]H2O PET study.

OBJECTIVE: The prefrontal-parietal circuits have been reported to play an important role in working memory. The purpose of this study was to use direct neuroimaging to address whether interregional correlation in the prefrontal-parietal circuits is ...

Mercury derived from dental amalgams and neuropsychologic function.

There is widespread concern regarding the safety of silver-mercury amalgam dental restorations, yet little evidence to support their harm or safety. We examined whether mercury dental amalgams are adversely associated with cognitive functioning in a ...

Mild cognitive impairment: prevalence and incidence according to different diagnostic criteria. Results of the Leipzig Longitudinal Study of the Aged (LEILA75+).

BACKGROUND: Although mild cognitive impairment is associated with an increased risk of developing dementia, there has been little work on its incidence and prevalence. AIMS: To report age-specific prevalence, incidence and predictive validities for four ...

Social cognition and neurocognitive deficits in schizophrenia.

While research equivocally supports a relationship between social cognition and neurocognition, it is less clear whether social cognition is related to general cognitive functioning or whether specific aspects of social cognition are linked with specific ...

Depressed mood and executive dysfunction in early Parkinsons disease.

OBJECTIVES: Studies on neuropsychological functions in early Parkinsons disease (PD) have reported changes with respect to memory and executive control related to dysfunction of fronto-striatal circuitry. The question has been raised, however, whether ...

Effect of age on regional cerebral blood flow patterns in Alzheimers disease patients.

The purpose of this study was to explore the influence of age on regional cerebral blood flow (rCBF) patterns in patients with Alzheimers disease (AD). Single photon emission computed tomography (SPECT) was performed in 79 patients with AD, including 31 ...

Gamma-band phase clustering and photosensitivity: is there an underlying mechanism common to photosensitive epilepsy and visual perception?

Photosensitive epilepsy (PSE) is the most common form of human reflex epilepsy, appearing in up to 10% of epileptic children. It also offers a highly reproducible model to investigate whether changes in neuronal activity preceding the transition to an ...

Unilateral subthalamotomy in the treatment of Parkinsons disease.

Hyperactivity in the subthalamic nucleus (STN) is seen in animal models of Parkinsons disease, and lesioning of the STN dramatically relieves the animals parkinsonism. Deep brain stimulation (DBS) of the STN is an effective treatment for patients with ...

Source versus content memory in patients with a unilateral frontal cortex or a temporal lobe excision.

It has been suggested previously that patients with a frontal lobe lesion might have a specific impairment in the retrieval of the source of information despite adequate memory for facts. Patients with an anterior temporal excision are known to have ...
