    Basal forebrain (BF) In neurodegenerative diseases, BF cholinergic neurons often degenerate, leading to subsequent cognitive decline


    β-Amyloid BF atrophy α-synuclein cholinergic deficiency Since cortical atrophy can reflect the pathological spreading pattern of AD and LBD, a comparative assessment of cortical thinning patterns associated with cholinergic atrophy and β-amyloid burden has Helps understand the two most common neurodegenerative diseases


    18F -flubetabine positron emission tomography with BF volume and cortical thickness (CTH) and β-amyloid load obtained by magnetic resonance imaging (MRI), neuropsychological assessment of cognitive function.




    18 Hypertension Diabetes

    • BF volume mediates the association of FBB-SUVR with cortical thickness in AD and LBD disease spectrum, whereas FBB-SUVR is associated with CTH independently of BF volume only in LBD disease spectrum


      There are common β-amyloidosis mechanisms in AD and LBD spectrum, with or without BF mediation, BF atrophy is more profoundly related to cognitive impairment, and localized β-amyloid is present in LBD disease spectrum and cortical atrophy
