Epidemiologie der Demenzen

  • Horst Bickel

Zusammenfassung

Zum Ende des 20. Jahrhunderts hat die Zahl der über 65jährigen in Deutschland knapp 13 Millionen erreicht. Nach konservativer Schätzung ist bis zur Mitte des nächsten Jahrhunderts bei überproportionaler Zunahme der Höchstbetagten ein anhaltendes Wachstum der Altenbevölkerung um wenigstens weitere vier Millionen Menschen zu erwarten. Zu den wichtigsten medizinischen, sozialen und ökonomischen Problemen, die durch den demographischen Wandel aufgeworfen wurden, zählt die Versorgung der hohen und fortgesetzt steigenden Zahl von Demenzerkrankungen. Der folgende Beitrag schildert, wie häufig Demenzen nach den Resultaten epidemiologischer Studien sind und wie sie sich in der Bevölkerung verteilen, stellt einige der Auswirkungen auf das Versorgungssystem dar und faßt den Kenntnisstand über Risikofaktoren der Alzheimer Demenz (AD) als numerisch bedeutsamster Demenzform zusammen.
