Title: Self-awareness, depression and neurocognitive functions in traumatic brain injury


Traumatic Brain Injury (TBI) is the most common cause of disability in young patients. In the self-awareness deficits that can arise after TBI, patients experience difficulties in understanding the disabilities resulting from their injury. This is an important problem that affects the rehabilitation processes. Materials and methods: Self-awareness, neurocognitive functions and depressive symptoms were observed in 31 outpatients with a diagnosis of moderate or severe TBI, aged between 16 and 45 years. Instruments: Patient Competency Rating Scale, Neurocognitive Assessment and Hamilton Depression Rating Scale. Results: Correlations were found between self-awareness and its dimensions with visuospatial skills, executive functions (double task and cognitive inhibition), episodic memory  and depressive symptoms. Conclusions: Patients who have suffered a moderate or  severe TBI may have impaired self-awareness. Self-awareness is the ability to objectively perceive (perceive our own self), while maintaining a sense of subjectivity, It is a complex function that needs to use executive functions and episodic memory. The relationship found between interpersonal self-awareness and depressive symptoms does not seem to be conclusive, since this association is probably more complex, and involves other variables not considered in this study.
