Role of Alternative and Augmentative Communication in Three Cases of Severe Acquired Brain Injury: A Neurorehabilitative Approach

Background: Augmentative and Alternative Communication (AAC) improved communicative skills in adults with post-stroke aphasia demonstrating the effectiveness in speech disorders and consequent improvement of patients’ communication skills. This study aimed to report the efficacy of AAC in the rehabilitation of cognitive disorders and to estimate how the changes in cognitive and communicative functions could enhance the quality of life in patients affected by severe acquired brain injury. Methods: Three patients with pontine cerebral ischemia, traumatic brain injury (TBI), and meningioma expressed in the posterior cranial fossa, respectively, were submitted to rehabilitative training with AAC for 6 months. Patients underwent to neuropsychological and mood evaluations at the beginning of AAC treatment (T0) and after rehabilitative training (T1). Results: The results support the efficacy of AAC in the improvement of cognitive functions, particularly in memory, attention, and language domains. In addition, we described also an improvement in the quality of life and a decrease in depressive symptoms. Conclusions: The AAC seems to be an important rehabilitative technique for the recovery of cognitive functions with a consequent effect in improvement of psychological aspects and quality of life in patients with Acquired Brain Injury (ABI).
