AbstractThe cerebellum is linked to motor coordination, cognitive and affective processing, in addition to a wide range of clinical illnesses. To enable robust quantification of individual cerebellar anatomy relative to population norms, we mapped the normative development and aging of the cerebellum across the lifespan using brain scans of >54,000 participants. We estimated normative models at voxel-wise spatial precision, enabling integration with cerebellar atlases.

AbstractDeep learning approaches for clinical predictions based on magnetic resonance imaging data have shown great promise as a translational technology for diagnosis and prognosis in neurological disorders, but its clinical impact has been limited. This is partially attributed to the opaqueness of deep learning models, causing insufficient understanding of what underlies their decisions.

For vel 20 år siden fikk en studie om sammenheng mellom inntak av vin og risiko for demens stor oppmerksomhet. Nesten 4000 personer over 65 år ble fulgt over tre år. Det viste seg at de som hadde et moderat forbruk av vin, definert som tre−fire glass per dag, hadde mindre sjanse for å få demens enn de som ikke drakk i det hele tatt. Forfatterne konkluderte med at eldre ikke behøvde å redusere vinforbruket for å minke risikoen for demens. Studien ble gjennomført i Bordeaux.
