[Diagnostic aspects of dyslexia].

For diagnosing dyslexia (Legasthenie) we describe a neurological, psychiatric and psychodiagnostic examination, which was practicable for clinical use. Furthermore we critical new trends in pedagogical and school-ministerial institutions neglecting clinical facts concerning the complexities of causes, primary and secondary symptoms of reading and writing disorders. Finally various scientific efforts are reviewed which aim at gaining more precise knowledge on the correlations between physiological brain processes and the normal or disturbed learning of reading and writing.
