Zusammenfassung

Zerebrale Läsionen aufgrund von Durchblutungsstörungen, Einblutungen, Verletzungen oder Tumoren können nicht nur zu motorischen oder sensiblen Ausfallserscheinungen führen, sondern sind oft ursächlich für Aufmerksamkeitsstörungen. Neben der Vigilanz und der Daueraufmerksamkeit kann dabei die Aufmerksamkeit für eine Raumhälfte betroffen sein. In solchen Fällen spricht man von (Hemi-)Neglekt. Leidet ein Patient an Neglekt, so sind die Aussichten auf eine Besserung der Symptome im Allgemeinen schlechter als bei Patienten ohne Neglekt, nicht zuletzt, weil das einseitige Aufmerksamkeitsdefizit zu einer Vernachlässigung ohnehin schon gelähmter Gliedmaßen führt und damit die Rehabilitation erschwert. Welche kog nitiven Prozesse bei Neglekt gestört sind, ist bereits seit Jahrzehnten Gegenstand neuropsychologischer Untersuchungen. Moderne bildgebende Verfahren haben diese ergänzt und in der letzten Zeit nicht unerheblich zum Verständnis des komplexen Krankheitsbildes beigetragen.
