- W2026178475 abstract "We wished to longitudinally assess early changes in cerebral perfusion (CP) and its relationship to cognitive impairment (CI) in ALS. Fourteen ALS patients at time of diagnosis and 11 spousal controls, both without CI, were longitudinally assessed to determine a relationship between CP and incidence of CI in early stage disease. Neuropsychological testing and CP measurements were performed in both ALS and control groups at the initial assessment (T0) and two time-periods post initial assessment, T1 and T2, taken on average 6.1 and 17.0 months after initial assessment (T0), respectively. CT perfusion was used to measure cerebral blood flow, blood volume, and mean transit time (MTT) for all cortical lobes, and subcortical grey and white matter. Two of 14 ALS patients progressed to CI. No differences in CP measurements existed at T0 or T1 between the ALS and control groups. At T2, widespread cortical differences in MTT were present between the two groups. The ALS group had significantly increased MTT in all cortical regions, as well as the thalamus, compared with the control group. Our findings suggest early widespread changes in CP occur outside the motor area in the absence of CI in ALS." @default.
