Tachylalia is defined as extremely rapid output of speech. A case of delayed development of tachylalia 4 years following sustaining a closed craniocerebral injury is reported. We suggest that the management of communication disorders should always be considered as a part of treatment and rehabilitation of traumatic head injury. In a detailed PubMed and Medline search for late-onset tachylalia, development following traumatic craniocerebral injury did not yield even a single report in the literature. The multidisciplinary approach in management of such rare event is highly crucial.
