CSF levels correlated with clinical upper motor neuron burden and rate of disease progression.
Results demonstrated that PLS patients were distinguished by widespread cerebral myelin water fraction reductions, independent of disease duration and clinical upper motor neuron burden.
In cross-sectional study, the core signature of white matter pathology was confirmed within the corticospinal tract and callosal body, and linked strongly to clinical upper motor neuron burden, but also to limb disability subscore and progression rate.
In the current study, we demonstrated the association of pTDP-43 within the cytoplasm of neurons burdened with pathological tau aggregates a tauopathy triggered solely by the expression of mutant human tau in transgenic mice.
Astrocytes accumulate higher levels of Mn than neurons and may be an initial site for Mn-induced damage, thus, lowering the neuronal burden of Mn [ 8].
An upper motor neuron clinical burden score out of 15 comprised the number of pathologically brisk reflexes [extensor plantar responses (2), brisk facial and jaw jerks (3), biceps (2), supinator (2), triceps (2), finger (2), knee (2), and ankle reflexes] (Turner et al., 2004).
To gain further insights into pathomechanisms of C9FTLD, sense and antisense neuronal RNA foci burden (percentage of neurons containing foci) were correlated with age at onset and age at death.
Conversely, the enhancement of autophagy induction by ENMs could play a role in improving the survival of neurons that are burdened with increased removal of aggregated proteins and mitochondria in the setting of neurodegenerative disease.
Amyotrophic lateral sclerosis (ALS) is characterized by heterogeneity in the region of onset, rate of progression, patterns of disease spread, and relative burden of upper motor neuron (UMN), lower motor neuron (LMN), and cognitive pathology.
We used the data available for the three variant types to perform power calculations for the Neuron projection (GO) gene-set burden test and three other gene-sets (Table S5).
Pathology studies in AD have shown high correlations between structural changes on MRI and Braak NFT stages [ 28], validating structural MRI as a biomarker for measuring neuron loss associated with NFT burden [ 115- 117].
