Improving Self-Awareness in Chronic Moderate-Severe Acquired Brain Injury: The Social Cognitive Communication...

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Cognitive Psychology

Background:

• Chronic moderate-severe acquired brain injury (MS-ABI) presents significant challenges in self-awareness and executive functions.
• Current rehabilitation strategies often require enhancement for optimal patient outcomes.

Purpose of the Study:

• To assess the feasibility of an integrated rehabilitation intervention.
• To combine social cognitive-communication (SocCom) training with transcranial direct current stimulation (tDCS).
• To improve self-awareness and executive functions in individuals with chronic MS-ABI.

Main Methods:

• A pilot study involving 25 individuals with chronic MS-ABI.
• Random assignment to either combined SocCom + tDCS or SocCom alone over 11 weeks.
• Neuropsychological, psychosocial, and functional near-infrared spectroscopy (fNIRS) assessments pre- and post-intervention.

Main Results:

• Both groups showed significant improvements in memory, executive functions, semantic knowledge, and quality of life.
• The combined SocCom + tDCS group exhibited significant neurophysiological changes via fNIRS.
• Superior gains in visual memory, executive function, and processing speed were observed in the combined intervention group.

Conclusions:

• The integrated SocCom and tDCS intervention is a promising strategy for MS-ABI rehabilitation.
• This combined approach enhances cognitive and psychosocial outcomes more effectively than SocCom alone.
• The findings support a personalized, holistic approach to recovery for individuals with chronic MS-ABI.
