Use of a comprehensive programme of external cueing to enhance procedural memory in a patient with dense amnesia

This case study describes rehabilitation efforts with a 24-year-old woman who exhibited dense amnesia secondary to status epilepticus following a motor vehicle accident. She was 20 months post-injury upon entry into our day treatment programme. The functional severity of her amnesia was reflected in numerous ways, including no recall of what she wore from day to day and an inability to find the toilet after 2 weeks in the programme. A multidisciplinary comprehensive programme of external cueing was established to exploit her preserved procedural memory. Objective measures of functional compliance were gathered over time and contrasted with both standard neuropsychological test scores and early levels of functioning in rehabilitation. Results demonstrated enhanced functioning via utilization of procedural memory. In addition, the patient actually demonstrated increased independent generalization of strategies and techniques over time. Practical treatment implications are reviewed and discussed.
