Our findings on serum VILIP-1 in AD patients showed increased concentrations compared to the Con group but the difference between the two groups was smaller than for CSF confirming the plasma measurements from Tarawneh et al. Furthermore, the significant difference between AD and PD spectrum, bvFTD, and ALS seen in CSF was not found for blood. Here, VSNL1 is linked to amyotrophic lateral sclerosis.
