P300 in Early Cognitive Impairment in Hepatitis C Virus

May 12, 2020 updated by: Ahmed Esmael, Mansoura University Hospital

Predictive Value of P300 Event-related Potential Component in Early Cognitive Impairment in Patients With Uncomplicated Newly Diagnosed Hepatitis C Virus

Approximately 50% of patients with hepatitis C have complaints of fatigue and cognitive deficits even before the development of significant hepatic impairment.

Detailed Description

Assessing the influence of HCV infection on the development of cognitive changes involves many challenges. The frequent presence of confounding factors such as illicit drug use, depression, and cirrhosis has the potential to produce cognitive impairment and therefore obscuring the role of HCV infection as a major actor in the development of cognitive impairment.

The presence of brain dysfunction in patients with liver cirrhosis is well known. Zeegen et al. described in 1970, through the use of neuropsychological tests, the occurrence of cognitive changes involving mainly psychomotor speed, attention, and executive function in cirrhotics who did not have clinical criteria for hepatic encephalopathy. This condition is currently called minimal hepatic encephalopathy.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
HCV patients
Patients with uncomplicated newly diagnosed hepatitis C virus
Diagnostic test: Visual Event-Related Potentials
Auditory P300-evoked brain potential: an eventrelated potential of cognitive neurophysiological significance. It represents the brain response to certain sensory/cognitive stimuli by paying attention to the different stimulus among the stereotypical ones (the auditory oddball paradigm). It measures mainly the decision-making process (Polich and Kok, 1995).
Control group
Age and sex matched with patients
Diagnostic test: Visual Event-Related Potentials
Auditory P300-evoked brain potential: an eventrelated potential of cognitive neurophysiological significance. It represents the brain response to certain sensory/cognitive stimuli by paying attention to the different stimulus among the stereotypical ones (the auditory oddball paradigm). It measures mainly the decision-making process (Polich and Kok, 1995).
