This study investigates the efficacy of high-tech Augmentative and Alternative Communication (AAC) systems in enhancing communication and overall quality of life for a 54-year-old female diagnosed with Multiple Sclerosis (MS), presenting with declining cognition and communicative abilities. A comprehensive test battery, incorporating the Addenbrooke’s Cognitive Examination-III Marathi (ACE III- M) and the Frenchay Dysarthria Assessment-Second Edition (FDA-2) revealed Mild Cognitive Impairment and Severe Mixed Dysarthria, respectively—a motor speech disorder contributing to diminished speech intelligibility. The intervention focused on introducing Tobii Dynavox PC eye mini device, involving instruction on computer and eye gaze device usage for the client as she had no prior computer experience. A structured treatment plan, comprising thrice-weekly speech therapy sessions, was implemented, with progress assessments conducted bi-monthly. The treatment strategy included speech therapy to improve phonation, implementation of a personalised AAC board featuring words and sentences, targeting cognitive abilities through attention and memory games. After 10 months of treatment, ACE III- M and FDA-2 was re-administered which suggested adequate cognitive skills and better speech intelligibility. The client demonstrated independent use of AAC software and laptop, with occasional technical support. Client and caregiver interview also stated improved communication in various setting, which boosted the clients confidence and hence improved overall quality of life. The study provides valuable clinical evidence for the adoption of high-tech AAC, encouraging therapists and clients to consider its benefits.
