Cerebral palsy is caused by damage to the infant brain. This damage can involve not only the motor parts of the brain, but also the parts that deal with vision. This is not related to damage to the eye but is related to damage of the parts of the brain that process visual information.
There is insufficient research on adults living with cerebral palsy, (as referenced in my previous blog post on cerebral palsy and adulthood). Although there is a paucity of studies examining mental health in this population, medical researchers have speculated that the rate of depression is three to four times higher in people with disabilities such as CP than it is in the general population.
