P300 event-related potential in late-onset schizophrenia.
P300 event-related potential in late-onset schizophrenia The P300 event-related potential (ERP) is a late positive waveform that is typically maximal at centroparietal midline sites 300 msec post-stimulus in simple categorization tasks. Reduction in auditory P300 amplitude has been widely reported in young schizophrenic patients. The degree of amplitude reduction has been related to the degree ...
متن کاملLate auditory event-related evoked potential (P300) in Down's syndrome patients.
UNLABELLED Down syndrome is caused by a trisomy of chromosome 21 and is associated with central auditory processing deficit, learning disability and, probably, early-onset Alzheimer's disease. AIM To evaluate the latencies and amplitudes of evoked late auditory potential related to P300 events and their changes in young adults with Down's syndrome. MATERIALS AND METHODS Prospective case stu...
متن کاملLate whiplash syndrome: correlation of brain SPECT with neuropsychological tests and P300 event-related potential.
BACKGROUND The acceleration forces infringing the cervical spine in whiplash injury are frequently associated with multiple cerebral symptoms. The purpose of this study was to determine whether there is a correlation between cerebral perfusion findings, P300 recording (an electrophysiologic marker of cognitive ability), and neuropsychological tests in patients with whiplash injury. METHODS Tw...
متن کاملThe Event-related Potential P300 in Patients with Migraine.
OBJECTIVE Recording of event-related potentials by using oddball paradigm of auditory P300 has yielded conflicting results in migraine. The aim of this study was to demonstrate that migraine patients have reduced P300 amplitude and prolonged P300 latency, suggesting alterations of the cognitive-evaluative component. METHODS We recruited 29 migraine patients (24 females; median age 40 years) a...
متن کاملP300 Event-Related Potential as an Indicator of Inattentional Deafness?
An analysis of airplane accidents reveals that pilots sometimes purely fail to react to critical auditory alerts. This inability of an auditory stimulus to reach consciousness has been coined under the term of inattentional deafness. Recent data from literature tends to show that tasks involving high cognitive load consume most of the attentional capacities, leaving little or none remaining for...
