FABP3 and vascular dementia: Given that the levels of FABP3 are significantly higher in the cerebrospinal fluid and serum of patients with AD, DLB, PD with dementia, and vascular dementia (VaD) than in healthy individuals, it has been proposed as a biomarker of neurodegeneration [47,48,49,50], with high levels of FABP3 being significantly associated with the development of dementia [10].
