Prevalence of Intellectual Disabilities and Epilepsy in Different Forms of Spastic Cerebral Palsy in Adults

Spastic cerebral palsy may be interconnected with other neurodevelopmental disorders such as intellectual disabilities, and epilepsy. Brain synaptic plasticity and successful restorative rehabilitation may also contribute to diminish neurological deficit of patients having cerebral palsy. The aim of this study was to investigate the prevalence of intellectual disabilities and epilepsy in adult patients with different forms of spastic cerebral palsy and to find out correlation between the severity level of intellectual disabilities and epilepsy.

Adults diagnosed with different forms of spastic cerebral palsy were analyzed during a three-month period. The investigated features were: gender and age; form of cerebral palsy; the prevalence of intellectual disabilities and epilepsy. Intellectual disabilities were divided into 4 severity levels. The correlation between the severity level of intellectual disabilities and epilepsy was statistically analyzed.

Intellectual disability was present in 55% of patients diagnosed with spastic cerebral palsy. Epilepsy was present in 36% of such patients. It was recorded in 51.1% of quadriplegic, 21.9% of diplegic, and 19.2% of hemiplegic patients. Intellectual disability was present in 73.8% of quadriplegic, 31.3% of diplegic, and 53.8% of hemiplegic patients. The statistically significant correlation existed between the severe intellectual disability and epilepsy.

Intellectual disabilities and epilepsy most frequently occurred in patients with most severe forms of spastic cerebral palsy. Epilepsy is strongly correlated to the severity level of intellectual disability. Such patients require additional special modes of treatment and restorative rehabilitation to improve the functional outcome.
