Question: Is Spastic diplegia cerebral palsy inherited ?
Answer: Is spastic diplegia cerebral palsy inherited? Scientists have found that family members of people with cerebral palsy, including spastic diplegia cerebral palsy, have an increased risk of developing the condition. The exact risk depends on the how closely the family members are related: A child with a sibling (brother, sister) or parent with cerebral palsy would have a six- to nine-fold increased risk of developing the condition (actual risk: 1 to 1.5%) A child with a half sibling with cerebral palsy would have up to a three-fold risk of developing the condition (actual risk: less than 1%) A child with a first cousin with cerebral palsy would have a 1.5-fold increased risk of developing the condition (actual risk: less than 1%) This suggests that there may be a genetic component in some cases of cerebral palsy. However, the inheritance is likely multifactorial which means the condition is caused by multiple genes interacting with each other and with environmental factors.
