Respiratory problems in the adolescent with developmental delay

Abstract

Patients with developmental disorders, including adolescents, comprise a large and heterogeneous group of individuals who vary in underlying diagnosis and degree of disability. The largest numbers of patients are those with cerebral palsy and with traumatic brain injury. While these conditions themselves do not directly cause airway or parenchymal lung dysfunction, consequences of neuromuscular dysfunction, especially aspiration and ineffective cough, may lead to lung damage. Poor nutritional status, impairment of airway clearance by muscular weakness or incoordination and poor pulmonary reserve (due to chest wall or spine deformity) increase the risk of significant morbidity and mortality from respiratory infections. Individuals who were premature infants or who had prolonged neonatal courses may also have residual chronic lung disease (bronchopulmonary dysplasia) contributing to their pulmonary problems. This review discusses conditions that have adverse effects on the airway and lung (drooling, feeding problems, gastroesophageal reflux, aspiration, spasticity, scoliosis) and some of the consequences of these insults (disordered airway clearance, pneumonia, sleep apnea). Also discussed are issues important to the prevention or amelioration of respiratory difficulties, including preventive care, the effects of exercise, dental hygiene, and surgical intervention.
