Verbal communication disorders in brain damaged post-stroke patients in Benin.

UNLABELLED: In Western countries, progress has lessened the severity of numerous sequels of verbal communication disorders (VCD). For Africa and more particularly Benin, few data on the subject are presently available.

OBJECTIVE

To analyze the occurrence and development of post-stroke VCD in Benin.

METHOD: A retrospective, descriptive and analytical study focused on 563 post-stroke patients treated in rehabilitation department of the National university hospital of Cotonou (CNHU) from January 2006 through December 2010.

RESULTS

VCD prevalence was 42.10%. Average age was 57.17 ± 12.62 years, sex ratio was 1.75, and 74.69% were right-handed. VCD affected oral expression (95.78%), written expression (2.11%), oral comprehension (13.08%) and written comprehension or reading (0.84%). Type of stroke, sex and age had no impact on VCD occurrence following stroke. Only 5.91% of the patients underwent speech therapy. Progression was favorable in 21.09% of the cases studied.

CONCLUSION

In Benin, post-stroke VCD is exceedingly common and occasions major social difficulties. Prevalence of VCD in a predominantly oral culture underscores the need for speech therapists to develop a more broadly ecological approach toward treatment.
