-year increase from 1960-1989 in the Australian study was 3.9% for twins and 67% for triplets. This has contributed to a significant annual increase in the proportion of multiple births associated with cases of cerebral palsy (6). Before 1970, 5.3 % of all cerebral palsy was in multiple births, in 1980, 6.6%, and in 1990, 10.3% (6).Multiple births are much more common now than in the past. Multiple pregnancies are fairly easy to identify as high-risk pregnancies for cerebral palsy. Because of the high susceptibility infants in multiple births have towards cerebral palsy, the trend of fertilization drugs needs to be carefully examined. There are several documentations about the risks that multiple pregnancies pose to the outcomes of cerebral palsy in the babies, and this is ground for concern for parents, children, and doctors....
