“…The reduction in the NAA/Cr ratio in the motor cortex was found to vary from 5% to 32% [50,[52][53][54]56,57]. NAA/ Cho is reduced more than NAA/Cr in the motor cortex in those studies that measured both [51,55,56,[58][59][60][61]. NAA/Cr and NAA/Cho ratios are reduced along the length of the intracranial CST from the motor cortex to the cerebral peduncle; however, this reduction is most significant rostrally in the pre-central gyrus and corona radiata [59].…”

NAA/Cr and NAA/Cho ratios are reduced along the length of the intracranial CST from the motor cortex to the cerebral peduncle; however, this reduction is most significant rostrally in the pre-central gyrus and corona radiata [59]. Nevertheless, 1 H-MRSI changes in the brainstem have also been reported in patients with ALS, with the greatest decrease of the NA (NAA + N-acetylaspartylglutamate)/Cr ratio in the pons and upper medulla of patients with prominent UMN or bulbar signs [62].…”

“…Αρνητική συσχέτιση προκύπτει μεταξύ της διάρκειας της νόσου και του δείκτη FA στην παρεγκεφαλίδα(Keil et al, 2012). Οι δείκτες διάχυσης του φλοιονωτιαίου σχετίζονται με τη διάρκεια της νόσου(Lombardo et al, 2009), με τους δείκτες διάχυσης του ετερόπλευρου φλοιονωτιαίου δεματίου να σχετίζονται με την σπαστικότητα(Pyra et al, 2010). Αναφορικά με τη νωτιαία ή προμηκικού τύπου έναρξη, υπάρχουν αναφορες για απουσία διαφορών μεταξύ των δύο ομάδων ασθενών στον δείκτη FA του φλοιονωτιαίου δεματίου ενώ μια άλλη μελέτη βρήκε σημαντικά διαταραγμένους τους δείκτες FA, MD και Dradial στην ομάδα με προμηκική έναρξη και όχι τον δείκτη Daxial (Cardenas-Blanco et al, 2014).…”
