There is no unanimity in the national and international scientific community regarding the definition of SCD, nor is there a unique and globally accepted identification of which pathologies and ages are encompassed by this term.
The DCS is the injury produced in the brain after birth that causes a decline in the health and quality of life of those who suffer it. Considering that the brain is the control organ of all vital functions, the lesions produced in it can affect any function of the organism in the form of physical, cerebral or sensory sequels.
When we refer to DCSI we are delimiting the brain injury that occurs in children and adolescents until the age of 18.
In the pediatric age it is necessary to define the DCSI of the infantile cerebral paralysis (PCI) and of the degenerative diseases of the nervous system. PCI is defined as a disorder of postural tone and movement, persistent but not invariable, secondary to a non-progressive aggression to an immature brain. The age limit is not clearly established, but the literature generally limits PCI to secondary injury to prenatal, perinatal and neonatal (first month of life) lesions.
Degenerative diseases of the nervous system are a group of diseases with deterioration in some neurological function, variable in symptomatology, etiology and age of presentation. Its own definition is its progressive character, but sometimes the progression is not clear at the onset of the disease and it is not uncommon for the onset of symptoms to be related to a traumatic event, which can lead to confusion.
Therefore, we should exclude from the definition of ISDC:
Problems occurring during gestation and at birth are excluded because they are “congenital”.
Complications and sequelae of prematurity are excluded, which are generally presented as infantile cerebral palsy, as they are considered to be related to birth.
