Rorschach, Bender, Rey Auditory Learning Test, Trail and some questionnaires as Audit, WHO-QOL Bref, Epworth scale as well as Quantitative EEG were also applied as part of their diagnostic workup. Results: Patients were 45 to 84 years old (mean 61.1 yrs); CDR scores were 0 to 3 (mean 0.7). The mean of the z score to P300 was 3.77 (SD 3.1). A moderate correlation was found for P300 latencies z-scores and CDR (r 0.493; p 0.009). Conclusion: P300 latencies measure seems to be a valuable method when a more objective test is needed in the evaluation of patients with cognitive dysfunction.
