Abstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by loss of motor neuron and various cognitive deficits including writing errors. (11)C-flumazenil (FMZ), the positron emission tomography (PET) GABA(A) receptor ligand, is a marker of cortical dysfunction. The objective of this study was to investigate the relationship between cognitive deficits and loss of neuronal integrity in ALS patients using (11)C-FMZ PET. Ten patients with ALS underwent both neuropsychological tests and (11)C-FMZ-PET. The binding potential (BP) of FMZ was calculated from (11)C-FMZ PET images. There were no significant correlations between the BP and most test scores except for the writing error index (WEI), which was measured by the modified Western Aphasia Battery - VB (WAB-IVB) test. The severity of writing error was associated with loss of neuronal integrity in the bilateral anterior cingulate gyrus with mild right predominance (n=9; x=4mm, y=36mm, z=4mm, Z=5.1). The results showed that writing errors in our patients with ALS were related to dysfunction in the anterior cingulate gyrus.
