BT There is great interest in identifying biomarkers of ALS to allow earlier diagnosis, recognize disease subtypes (which exist phenotypically), monitor disease progression, and assess the efficacy of therapeutic interventions. It is now generally accepted that DVAs are variations in venous drainage of normal brain parenchyma. Nevertheless, the widening grooves and fissures of the cerebral cortex indicate progressively severe brain atrophy and loss of brain mass. alterations of the blood–brain barrier (BBB) are thought to prevent ASDs from entering the brain parenchyma in necessary amounts, thereby being involved in causing drug-resistant epilepsy. Disease progression rate was calculated by dividing the number of points ALSFRS-R score decreased from normal (i.e., 48) at the time of neuroimaging by symptom duration in months [9]. bv. 2018 Oct;49(10):2504-2507. doi: 10.1161/STROKEAHA.118.022367. Growing evidence from neuroimaging and clinical studies indicates that ALS manifests with distinct clinical phenotypes identified by extent of upper motor neuron (UMN) dysfunction [2], cognitive impairment (ALS patients with frontotemporal lobe dementia, ALS-FTD), and variable degrees of lower motor neuron dysfunction.
