All participants were male and were assessed by Wechsler working memory. The performance of the two groups was compared using multivariate analysis of variance.

The difference between the two groups in the visual memory span was statistically significant (p <0.05) and the difference between the two groups in other subdomains of working memory test were statistically significant (p <0.01). In general, coma patients showed a poorer performance than the healthy group.

Hence, it is strongly suggested that in clinical and legal evaluations of the patients, this issue to be considered and both psychological and medical interventions done simultaneously to facilitate the treatment process and cognitive rehabilitation of the patients and to prevent individual, social and financial consequences and costs associated with a coma.
