Communication disorders that are found in children can be due to genetic factors or occur during pregnancy.  Communication disorders are discovered when the child fails to develop communications skills.  Some communication disorders are the result of an accident or injury.  Some of the causes of communication problems can be found by these:


• Craniofacial anomalies


• Oral anomalies (cleft lip/palate, dental malocclusion, macroglossia, oral-motor     dysfunction)


• Pharyngeal anomalies (upper airway obstruction, velopharyngeal insufficiency/incompetence)


• Laryngeal anomalies (vocal fold pathology, tracheal stenosis, tracheostomy, respiratory compromise)


• Auditory problems (hearing loss or deafness)


• Neurological disease/dysfunction (head trauma, brain stem injury, developmental   or cognitive disorder, etc.)


• Psychiatric disorders (psychosis, schizophrenia, etc.)


• Environmental deprivation


• Prematurity or traumatic birth


• Developmental disorders (developmental delay, pervasive developmental disability, autism spectrum, etc.)
