[5] Physical abnormalities such as cleft plate and other anomalies that affect oral, pharyngeal, laryngeal structures or neuromuscular functions can be a cause of Expressive Language Disorder by interfering with the patients ability to communicate directly.
[10] The prognosis of this disease is shown to be associated with a class of different issues ranging from broad areas of development in a child's life quality such as social relationships, mental health, literacy, academic abilities, community connections, etc.
Risk detection as well as the severity of the disease has also been linked to age and analyzed through the measurement of the ways these areas have been affected as the child reaches adolescence or adulthood.
[11] Additionally, an expressive language disorder that is not caused by any underlying diseases such as autism or brain tumors has been shown to be curable through means that do not involve direct forms of treatment such as medication.
In order to tackle and navigate through these difficulties, it is highly recommended for parents to seek out a speech language pathologist and to incorporate a routine that aids the child's condition at home such as an atmosphere where the encouragement for questions and active communications is endorsed.
The procedural memory system is associated with basal-ganglia circuits in the frontal lobe and further investigation of this particular hypothesis could aid in the development of a clinical neurological picture of what the underlying causes of SLI are.
Paul Broca was the first to note that the left hemisphere of the brain appeared to be localized for language function, particularly for right handed patients.
[17][18] In 1990, it was reported that the several generations of the KE family had developmental verbal dyspraxia and orofacial praxis that were inherited in a typical autosomal dominant pattern.
[20] Neuroimaging techniques, such as structural and functional MRI, found no significant differences between individuals with SLI and normal controls.
[20] Due to the vague nature of the diagnosis of expressive language disorder, there is little specific scientific research that we can currently locate.
A larger body of research exists around neuroscientific studies with children diagnosed with a specific language impairment (SLI).
[23] Other in-depth imaging studies report finding previously undiagnosed lesions in the brains of children with well-characterized developmental language development.
As Whitehouse and his colleagues [25] suggest, "When childhood language problems persist into adulthood, they can have far reaching consequences in terms of academic, social and vocational outcomes."
These researchers found that children diagnosed with an SLI would have persistent problems with language and are more likely to pursue vocational training rather than university, thereby avoiding professions requiring high levels of literacy.
