The Nervous System (NS) is affected in patients with Sickle Cell Anemia (SCA). The Visual Temporal Resolution (VTR) is considered as a measure of processing speed and cortical activation. It is used as general indicator of NS functioning, and it can be tested by Critical Frequency Fusion (CFF). The CFF was examined in 84 patients without previous neurologic events and the same amount in healthy subjects. The par­ticipants were ranging in age from 8 to 68. The patients’ hemoglobin level was measu­red at the moment of the neuropsychological assessment. The patients’ CFF was signi­ficantly lower than healthy people. Age correlated inversely with CFF, and statistically significant associations between hemoglobin and CFF was not found. We concluded that VTR is diminished en patients with SCA, which suggests that neurodevelopment is affected due to SCA.
