Language impairment refers to difficulties or limitations in a person's ability to understand, use, or produce language. This can manifest in a variety of ways, including difficulty with vocabulary, grammar, sentence structure, and communication skills. Language impairment can affect both spoken and written language, and can occur in individuals of all ages. Research in the area of language impairment seeks to better understand the underlying causes and mechanisms of language difficulties, as well as to develop effective assessment and intervention strategies to help individuals with language impairments improve their communication skills. Researchers may investigate factors such as genetics, brain development, and environmental influences on language impairment, as well as how to tailor interventions to meet the specific needs of individuals with language difficulties. This research can have important implications for improving academic achievement, social communication, and overall quality of life for individuals with language impairments.
