Abstract:
Often, standard aphasia batteries do not fully characterize higher-order cognitive-linguistic sequelae associated with a traumatic brain injury (TBI). Limited understanding and detection of complex linguistic deficits have thwarted efforts to comprehensively remediate higher-order language deficits that persist even in chronic stages of recovery post-TBI. This chapter reviews key precursor metrics that have motivated efforts to elucidate higher-order language proficiencies after a TBI. The chapter further expounds on a paradigmatic shift away from sole focus on lower level basic skills, towards a more top-down cognitive control approach to measure, retrain, and strengthen complex language abilities in TBI. The intricate relations between complex language abilities and cognitive control functions are also discussed. The concluding section offers promising directions for future research and clinical management based on new discoveries of higher-order language impairments and their modifiability in TBI populations.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
01:13Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
