Rehabilitation of lexical and semantic communicative impairments: An overview of available approaches

Lexical-semantic impairments are common consequences of acquired neurological damage. However, little is known about the benefits of existing treatment methods for this type of language impairment. Objective To evaluate current research into lexical-semantic interventions for adults with dementia, TBI or stroke. Methods The PubMed, PsycInfo and SCOPUS databases were searched for studies related to rehabilitation, neurological conditions, communicative and lexical-semantic skills published between 2004 and 2014. Results Twenty-eight of the 453 abstracts found were selected for the review based on the PRISMA method. Most of the studies described treatments for anomia. Semantic tasks were the most commonly used, followed by phonological and gestural strategies. Interventions were individual and involved formal tasks, although the number, frequency and duration of sessions varied between studies. Conclusion Although lexical-semantic interventions lead to improvements in language abilities, they are still poorly described in the literature, and must be further investigated in terms of their efficacy, effectiveness and long-term effects.
