The motor band sign in ALS: Presentations and frequencies in a consecutive series of ALS patients

The primary role of magnetic resonance imaging (MRI) in routine diagnostic work-up of motor neuron disease patients is currently still largely limited to exclusion of relevant non-degenerative pathologies. We here present an illustrative case of a 63-year-old woman with early stage Frontotemporal-Dementia-Amyotrophic-Lateral-Sclerosis (FTD-ALS) spectrum disorder showing a striking hypointense signal of the cortical band along the precentral gyrus, termed “Motor Band Sign” (MBS). Based on this finding, we analysed the frequency of the MBS in clinical routine MRIs in a large consecutive series of ALS patients (MRIs available from 157 patients).

Handwriting Boosts Brain Connectivity and Learning

Handwriting, compared to typing, results in more complex brain connectivity patterns, enhancing learning and memory. This study used EEG data from 36 students to compare brain activity while writing by hand and typing. from Neuroscience News https://ift.tt/0bklQBj

More Education, Longer Life: Global Study Reveals Link

A new study reveals that higher education levels significantly reduce the risk of death, regardless of age, sex, location, or background. Researchers found that each additional year of education decreases death risk by two percent, with 18 years of education lowering it by 34 percent. from Neuroscience News https://ift.tt/oeK38Fk
