Table 1 Clinical characteristics and neuropsychological performance at baseline and through clinical follow-up at 6, 12 and 24 months from the baseline: comparison between fast decliners and slow decliners.

From: NFL strongly correlates with TNF-R1 in the plasma of AD patients, but not with cognitive decline
