Das Altern stört die Fähigkeit des Gehirns, Schlüsselproteine zu produzieren, wodurch eine Kaskade von Funktionsstörungen ausgelöst wird, die zu altersbedingten Rückläufen und neurodegenerativen Erkrankungen beitragen. Beim Altern killifisch (kurzlebiger Wirbeltier, das als Modell für das Altern verwendet wird) wird das Gehirn bei der Übersetzung von Proteinen weniger effizient.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:
A recent study published in the journal Aging sheds light on how **aging interferes with the brain’s ability to produce key proteins, potentially triggering a cascade of dysfunctions that contribute to age-related decline and neurodegenerative diseases. The researchers found that in aging killifish (a short-lived vertebrate used as a model for studying aging) the brain becomes less efficient at translating specific types of proteins**. These disruptions appear to be driven by ribosomal stalling during protein synthesis, rather than changes in gene expression.
