Even if, in recent years, the study of language disorders in brain-damaged patients has been strongly influenced by models and experimental paradigms of cognitive neuropsychology, much less relevant has been the impact of this new approach to language rehabilitation. Contrasting opinions exist on this subject among clinicians and researchers. Some authors maintain that cognitive neuropsychology has not changed and will not change the treatment of aphasia. Other authors adopt a less pessimistic attitude, either reporting empirical data that support this viewpoint, or trying to define more precisely theoretical models, patient's characteristics and treatment paradigms that should improve the efficacy of cognitively oriented treatments.
The main scope of the present volume, which is mainly based upon contributions presented at a workshop on the relationships between cognitive neuropsychology and aphasia rehabilitation, is to make the point on this controversial issue. The volume includes several theoretical papers discussing the role of the cognitive approach in the development of language rehabilitation (Shallice; Basso & Marangolo; Best & Nickels), as well as specific examples of the application of cognitive models to the treatment of disorders of written language (Luzzatti, Colombo, Frustaci & Vitolo) and of sentence-level impairments (Springer & Huber; Mitchum, Berndt & Greenwald). Two review papers, dealing with the pragmatic approach to aphasia rehabilitation (Carlomagno, Santoro, Labruna & Blasi) and with neuroimaging studies of recovery (Cappa) complete the issue.
The papers incorporate elements of the lively discussion, which took place among the restricted number of participants at the workshop, on a number of controversial issues. Leading among them were the fundamental questions: has cognitive neuropsychology given up to now a significant contribution to aphasia rehabilitation, and what can be expected in the future. We hope that the moderately optimistic view that emerged from the workshop will be shared by readers of this special issue.

The study of patients affected by disorders of the central nervous system is one of the crucial research methods for investigating the organization of cognitive functions in the brain. However, many clinicians remain unaware of the significant advances that have taken place in the field of cognitive neuroscience in the last decades. This book provides an introduction to the cognitive and behavioural aspects of the clinical practice of neurology. Most of the contributors to this book combine an active clinical practice with a leading role in their respective research area, and have provided concise summaries of the theoretical advances which they consider as potentially relevant for the clinical evaluation and treatment of patients. This general approach has led to a format which is different from the many textbooks of neuropsychology that have appeared in the last few years. The organization of the material follows the main issues of diagnostic evaluation, clinical presentation and management. As a consequence, the book deals not only with the classical neuropsychological syndromes associated with stroke and degenerative dementias, but also with other common clinical conditions, such as multiple sclerosis, head injury, epilepsy and psychiatric disorders, which are often neglected in neuropsychology textbooks. Cognitive Neurology will be essential for neurologists in training, who want to understand how the observations they make everyday in the clinic relate to the expanding knowledge about the organization of cognition and emotion in the human brain. It will also be of interest to psychologists and cognitive neuroscientists, speech and language clinicians and rehabilitation specialists and psychiatrists.

Il volume presenta i lavori di revisione della letteratura relativa alla riabilitazione neuropsicologica effettuati come lavoro preparatorio per la "Consensus Conference "sulla Riabilitazione neuropsicologica che si e tenuta a Siena nel febbraio del 2010 sotto gli auspici di una serie di associazioni e societa scientifiche e professionali. L'approccio usato in modo comune in tutte le revisioni e quello della "evidence-based medicine" che consente di arrivare a delle raccomandazioni sull'efficacia dei diversi trattamenti riabilitativi con un solido ancoraggio nella letteratura scientifica internazionale.

Alla stesura di queste revisioni hanno partecipato i principali esperti neuropsicologi italiani. Il volume rappresenta cosi un "update" fondamentale per il professionista (fisiatra, logopedista, neurologo, neuropsicologo, psicologo, terapista della riabilitazione, terapista occupazionale)che svolge la sua attivita nell'ambito della riabilitazione neuropsicologica."
