An individualized memory retraining program after closed-head injury: a single-case study.

A memory-retraining program was designed for a patient approximately 2 1/2 months after he suffered a closed-head injury. Tests showed his memory deficit to be relatively isolated in the verbal sphere. An attempt was made to design a program in which tasks resembled the environmental demands on the patient for retention of verbal material. On a routine basis, the patient was read various paragraphs and was subsequently required to write them from memory. Three different strategies were used in an attempt to improve memory. After 15 days of training, the patient improved from an impaired level of verbal recall to a normal level. Strategies employing (a) visual imagery and other mnemonic devices and (b) questioning during presentation appeared to be most effective in facilitating retention. There was some drop in memory performance at a 9 month follow-up, and the patient was encouraged to resume active use of mnemonic strategies. Implications for further study are discussed.
