Cognitive deficits are among the most disabling consequences of
traumatic brain injury (TBI), leading to long-term outcomes and interfering with
the individual's recovery.
One of the most effective ways to reduce the impact of
cognitive disturbance in everyday life is cognitive rehabilitation, which is
based on the principles of brain neuroplasticity and restoration. Although there
are many studies in the literature focusing on the effectiveness of cognitive
interventions in reducing cognitive deficits following TBI, only a few of them
focus on neural modifications induced by cognitive treatment. The use of
neuroimaging or neurophysiological measures to evaluate brain changes induced by
cognitive rehabilitation may have relevant clinical implications, since they
could add individualized elements to cognitive assessment. Nevertheless, there
are no review studies in the literature investigating neuroplastic changes
induced by cognitive training in TBI individuals. OBJECTIVE: Due to lack of data,
the goal of this article is to review what is currently known on the cerebral
modifications following rehabilitation programs in chronic TBI. METHODS: Studies
investigating both the functional and structural neural modifications induced by
cognitive training in TBI subjects were identified from the results of database
searches. Forty-five published articles were initially selected.
Of these, 34
were excluded because they did not meet the inclusion criteria. RESULTS: Eleven
studies were found that focused solely on the functional and neurophysiological
changes induced by cognitive rehabilitation. CONCLUSIONS: Outcomes showed that
cerebral activation may be significantly modified by cognitive rehabilitation, in
spite of the severity of the injury.
