Gli elevati livelli d'inquinamento atmosferico aumentano il rischio di contrarre, oltre a diverse malattie respiratorie, oncologiche e cardiovascolari, anche la sclerosi multipla, stando alle conclusioni di uno studio condotto da una squadra internazionale, guidata dal Lilian Calderon-Garciduenas, del Centro di neuroscienze funzionali e strutturali dell'Università del Montana.
L'analisi, di cui riferisce la Revue Neurologique, si concentra in particolare sugli effetti delle polveri fini e degli ossidi d'azoto. Ne risulta che diffuse neuroinfiammazioni, danni all'apparato neurovascolare e produzione di anticorpi contro le proteine neurali sono risultati più preoccupanti nei bambini cronicamente esposti a concentrazioni di smog superiori alle norme. Si dimostra inoltre che ozono e particolato possono significativamente stimolare l'insorgere del morbo di Alzheimer in età avanzata.
