Lastly, little is known about MAO-B brain expression levels in ADRD, including Lewy body diseases (LBD), primary tauopathies [e.g., Pick’s disease (PiD), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD)], and frontotemporal lobar degeneration with Tar DNA-binding protein of 43 kDa (FTLD-TDP). The gene discussed is MAOB; the disease is corticobasal degeneration disorder.
