Sleep deprivation differentially impairs cognitive performance in abstinent methylenedioxymethamphetamine ("Ecstasy") users.

2 Nov 2009 Methylenedioxymethamphetamine (MDMA; "Ecstasy") is a popular recreational drug and brain serotonin (5-HT) neurotoxin. Neuroimaging data indicate that some human MDMA users develop persistent deficits in brain 5-HT neuronal markers. Although the ... Read more...

Incidence of and risk factors for cognitive impairment in an early Parkinson disease clinical trial cohort.

Nov 2009 OBJECTIVE: To investigate the incidence of and risk factors for cognitive impairment in a large, well-defined clinical trial cohort of patients with early Parkinson disease (PD). METHODS: The Mini-Mental State Examination (MMSE) was administered ... Read more...

Altered effect of dopamine transporter 3'UTR VNTR genotype on prefrontal and striatal function in schizophrenia.

30 Oct 2009 CONTEXT: The dopamine transporter plays a key role in the regulation of central dopaminergic transmission, which modulates cognitive processing. Disrupted dopamine function and impaired executive processing are robust features of schizophrenia. ... Read more...
