The other synaptic markers, including four other synaptic vesicle proteins (synaptotagmin‐1, SNAP25, syntaxin‐1B, and syntaxin‐7), generally show the reverse pattern, with higher values in AD for synaptotagmin‐1, SNAP25, syntaxin‐1B, and syntaxin‐7 (trend‐level). Here, SNAP25 is linked to Alzheimer disease.
