Poor balance when sitting, lack of control of the head, mouth, and trunk, not being able to bend the hips enough to allow the arms to stretch forward to reach and grasp food or utensils, and lack of hand-eye coordination can make self-feeding difficult. Feeding difficulties are related to higher GMFCS levels. Dental problems can also contribute to difficulties with eating. Pneumonia is also common where eating difficulties exist, caused by undetected aspiration of food or liquids. Fine finger dexterity, like that needed for picking up a utensil, is more frequently impaired than gross manual dexterity, like that needed for spooning food onto a plate. Grip strength impairments are less common.Children with severe cerebral palsy, particularly with oropharyngeal issues, are at risk of undernutrition. Triceps skin fold tests have been found to be a very reliable indicator of malnutrition in children with cerebral palsy. Language
Speech and language disorders are common in people with cerebral palsy. The incidence of dysarthria is estimated to range from 31% to 88%, and around a quarter of people with CP are non-verbal. Speech problems are associated with poor respiratory control, laryngeal and velopharyngeal dysfunction, and oral articulation disorders that are due to restricted movement in the oral-facial muscles. There are three major types of dysarthria in cerebral palsy: spastic, dyskinetic (athetotic), and ataxic.Early use of augmentative and alternative communication systems may assist the child in developing spoken language skills. Overall language delay is associated with problems of cognition, deafness, and learned helplessness.
The effects of cerebral palsy fall on a continuum of motor dysfunction, which may range from slight clumsiness at the mild end of the spectrum to impairments so severe that they render coordinated movement virtually impossible at the other end of the spectrum. Although most people with CP have problems with increased muscle tone, some have normal or low muscle tone. High muscle tone can either be due to spasticity or dystonia.Babies born with severe cerebral palsy often have irregular posture; their bodies may be either very floppy or very stiff. Birth defects, such as spinal curvature, a small jawbone, or a small head sometimes occur along with CP. Symptoms may appear or change as a child gets older. Babies born with cerebral palsy do not immediately present with symptoms. Classically, CP becomes evident when the baby reaches the developmental stage at 6 to 9 months and is starting to mobilise, where preferential use of limbs, asymmetry, or gross motor developmental delay is seen.Drooling is common among children with cerebral palsy, which can have a variety of impacts including social rejection, impaired speaking, damage to clothing and books, and mouth infections. It can additionally cause choking.An average of 55.5% of people with cerebral palsy experience lower urinary tract symptoms, more commonly excessive storage issues than voiding issues. Those with voiding issues and pelvic floor overactivity can deteriorate as adults and experience upper urinary tract dysfunction.Children with CP may also have sensory processing issues. Adults with cerebral palsy have a higher risk of respiratory failure.
