How can the quality of speech therapy work for individuals with aphasia, dyslexia, and dysgraphia be ensured in the absence of universally applicable therapeutic materials? Utilize the findings from numerous studies on already tested disorder-specific therapy methods compiled in this work. The authors guide you step by step: What are the causes of language comprehension and word retrieval difficulties, semantic disorders, and writing and reading impairments? What therapeutic approach is appropriate for these causes, and which study evaluates it? How can I transfer the therapeutic approach into practical work? What does the structure of the therapy materials look like, and what essential aspects should be considered? This book makes it easier for you as a speech therapist to handle the demanding case-specific treatment.
