“…There is a growing body of knowledge about how gesture becomes particularly important for enhancing communication when language is impaired after brain injury (e.g., in post-stroke aphasia). Yet, there is comparatively little known about how gestures are utilized by individuals with traumatic brain injury, which can result in cognitive-communicative differences that share some similarities with aphasia (e.g., anomia, a naming impairment), but differ in other aspects (e.g., more memory impairments; Chabok et al, 2012;Coelho, 2021;Kerr, 1995).…”

The use of hand gestures during communication is a naturally occurring phenomenon thought to aid in cognitive processes such as language, memory, and learning. Co-speech gestures increase in individuals with language impairment after brain injury, e.g., post-stroke aphasia. Traumatic brain injury (TBI) provides a unique avenue to evaluate gestures, as individuals with TBI often present with both anomia and cognitive impairments, resulting in cognitive-communicative disorder. Broadly, this study examines the extent to which iconic gestures are present in procedural narratives post moderate-severe TBI, and their stability across a period of longitudinal recovery. This study has several aims: (1) identify longitudinal changes in overall iconic gesture frequency, (2) examine longitudinal iconicity representation, (3) examine the relationship between language assessment scores and iconic gesture use, and (4) quantify the use of iconic gestures that are supplemental to speech, i.e., add to, disambiguate, or replace speech. Archival audiovisual data was drawn from a previous longitudinal study investigating communication recovery in moderate-severe TBI. We found that gestures were employed consistently across 2 years. Additionally, we found a high proportion of iconicity types, which were also used consistently longitudinally. We found that participants did not employ many gestures that were supplemental to speech, however there is some evidence that under severe language impairment, gestures may be employed for conveying information that is not available in speech. This study extends previous TBI and aphasia gesture research, suggesting that gestures and speech are highly connected speech processes, and that gestures are consistent over time.

Background & Aims:The present retrospective study examines veterans and military personnel who have sustained a cognitive-communication deficit/disorder (CCD) and/or aphasia secondary to traumatic brain injury (TBI).The prevalence of each disorder secondary to TBI is identified and demographic factors are analysed to determine whether specific characteristics (age, gender, race and/or ethnicity) differentially influenced diagnosis (CCD or aphasia). Methods & Procedures: A retrospective analysis examining the prevalence of CCD and aphasia among US service personnel with a complicated mildto-severe TBI treated over a 4-year period (1 January 2016-31 December 2019) was conducted. Medical diagnoses and demographic factors were obtained from administrative data repositories and a logistic regression was performed to identify the relationship between demographic factors and diagnoses.Outcomes & Results: Analyses revealed that 8.8% of individuals studied had a secondary diagnosis of CCD (6.9%), aphasia (1.5%) or both (0.4%). This signifies 6863 cases of CCD, 1516 cases of aphasia and 396 cases of CCD and aphasia (dual diagnosis) per 100,000 individuals who have sustained a complicated mild-tosevere TBI. The proportion of cases observed with these diagnoses was consistent with the racial, gender and ethnic demographics of those diagnosed with TBI. Statistical modelling revealed that increased age is predictive of a diagnosis of aphasia relative to CCD. Conclusions & Implications: Service personnel sustaining TBIs are at increased risk of communication impairments with deficits observed across all gender, racial and ethnic demographics. CCD is more commonly observed than aphasia, though clinicians should be cognisant of both when performing assessments. Age is a factor that can influence diagnosis.
