Neurological complications of sickle cell anaemia at the Kenyatta National Hospital : A 5 year retrospective study
MetadataShow full item record
In a five year retrospective study of 360 patients with homozygous (SS) sickle cell disease, eighteen (5%) were found to have neurological complications. Their ages ranged from 7 months to 21 years with a mean of 11.1 +/- 6 years. Of those with neurological complications, twelve (67%) of the patients had cerebrovascular accident, six (33.3%) convulsions, three visual disturbance; one sensorineural deafness, one cerebellar degeneration and the last one confusion and hallucinations. Four of the patients had multiple neurological complications. There was only one patient with recurrence of neurological complications. Two patients were hypertransfused and up to the end of the study period none of them had any recurrence. The pattern of neurological complications are similar to that observed in other studies. However, in this study, there were fewer recurrences of neurological complications.
