Diese Arbeit bestätigt Sturzangst als Einflussfaktor auf Stürze bei IPS-Patienten.

Als neue Information findet sich in dieser Arbeit eine Assoziation von links-temporalen WML mit dem Vorkommen von Stürzen. Diese kann durch Beeinflussung von Gedächtnis, Navigationsfähigkeit, Orientierung, auditiver Verarbeitung und Angstkonditionierung erklärt werden, da diese Fähigkeiten in diesem Hirnareal ‚durchgeführt‘ werden und zumindest für einen Teil dieser Fähigkeiten Hinweise für eine Lateralisierung bestehen. Diese Arbeit kann somit als Basis für weitere und möglicherweise spezifischere Arbeiten auf dem Gebiet der Sturzerfassung und -analyse bei IPS dienen.
