DYSLEXIA – AN OVERVIEW OF ASSESSMENT AND TREATMENT METHODS

Abstract

This article will give an overview of the different methods of assessment and treatment
currently used in the field of dyslexia with a special focus on genetic research. Based on the
modification and extension of the multilevel model of Valtin (1989, modified by Witruk,
1993b), assessment and treatment methods will be discussed due to their primary objectives.
These methods will be described regarding primary causes (biological risk factors), secondary
causes (partial performance deficits), primary symptoms (reading and writing problems) and
secondary symptoms (emotional and behavioural disorders).
Keywords: Multilevel model of dyslexia, genetics, magnocellular deficit, partial performance
