Cerebral palsy is not a disease, neither contagious nor inheritable. It is very rear for two cases to be found in the same family, and when a child is born with cerebral palsy it is not his/her parents' fault.

The causes of cerebral palsy are various and down to prenatal, perinatal and postnatal impairments. Sometimes, there might be more factors responsible for the cause of brain damage.

The exact definition of the etiological factor is not always easy, because there are often indications but not enough evidence, while there is an important percentage of cases where the causes remain unknown. The delineation of the particular etiological factor for brain damage is achieved to a percentage of 50-75%. It is wrong to claim that, in any case of cerebral palsy, the cause is attributed to difficulties during delivery, as it was initially assumed by John Little (1862), who identified cerebral palsy with difficult delivery and premature birth. It should also be noted that many children who present with predisposing factors for cerebral palsy in their prenatal, perinatal and postnatal medical record, do not necessarily develop cerebral palsy (Blair 1992 and 1993·Lamb 1992·Paneth 1993·Stanley 1994).

In the past few years, the imaging methods gave solutions in certain cases, where the etiological factor was unclear.
