Abstract
Aim: To examine cognitive-communicative functioning in adults with Mild Cognitive Impairment due to Alzheimer’s disease (MCI-AD) and compare performance with cognitively healthy older adults using the Bulgarian-adapted version of the Scales of Cognitive and Communicative Ability for Neurorehabilitation (SCCAN-BG).
Methods: This cross-sectional comparative study included 60 participants: 30 individuals with MCI-AD and 30 cognitively healthy controls comparable in education. Cognitive-communicative functioning was assessed across SCCAN domains, including orientation, memory, attention, oral expression, auditory and reading comprehension, writing, and problem solving. Group differences were analysed using non-parametric statistical methods.
Results: Overall SCCAN performance was lower in the MCI-AD group. Consistent group differences were observed in memory, attention, oral expression, and problem solving. These differences suggest reduced efficiency in tasks that require integrated cognitive-communicative processing. Reading comprehension and writing were largely preserved. Auditory comprehension showed a non-significant trend towards lower performance in the MCI-AD group.
Conclusion: Cognitive-communicative changes are evident at the MCI-AD stage and extend beyond memory impairment alone. The SCCAN-BG captures early, functionally relevant vulnerability in everyday communication. This supports its use for clinical monitoring and rehabilitation-oriented decision-making in populations at risk for Alzheimer’s disease–related cognitive decline.
