اختلال خاص زبان به عنوان اختلالات توسعه سیستمیک

The underlying cause of SLI is unknown and the numerous studies on the subject suggest that there is no single cause. We suggest that SLI is the result of an abnormal development of the language system, occurring when more than one part of the system fails, thus blocking the system's natural compensation mechanisms. Since compensation also hinders linguistic evaluation, one possibility for diagnosis and remediation control is to assess basic cognitive abilities by non-linguistic means whenever possible. Neurological plausible bases for language and language development should also be taken into account to offer new hypotheses and research issues for future work on SLI.
