Expressive language disorder is one of the "specific developmental disorders of speech and language" recognized by the tenth edition of the International Classification of Diseases (ICD-10). As of the eleventh edition (ICD-11, current 1 January 2022), it is considered to be covered by the various categories of developmental language disorder. Transition to the ICD-11 will take place at a different time in different countries.

The condition is a communication disorder in which there are difficulties with verbal and written expression. It is a specific language impairment characterized by an ability to use expressive spoken language that is markedly below the appropriate level for the mental age, but with a language comprehension that is within normal limits. There can be problems with vocabulary, producing complex sentences, and remembering words, and there may or may not be abnormalities in articulation.

Careful diagnosis is also important because "atypical language development can be a secondary characteristic of other physical and developmental problems that may first manifest as language problems".

Causes
Expressive language disorder is not well understood. It does not have one singular cause, but rather is often a result of many possible causes during development including malnutrition, and damage to the cerebrum such as from injury or disease. 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. Environmental problems during early childhood development, including inadequate stimulus, are risk factors as well.

Symptoms
Expressive Language disorder is characterized by difficulty communicating in varied ways. Sometimes this manifests as below-average vocabulary skills for an individuals age or use of the incorrect tense when speaking. There can be difficulty forming complex sentences and remembering words. Difficulties are with expression, not with understanding as with Receptive Language Disorder

Diagnosis
Diagnosis for expressive language disorder in children are usually marked by milestones markers of the child age grouping. A child can be diagnosed for expressive language disorder as early as two years old. Many pediatricians and speech and language pathologists look into all grounds of what may be causing speech delay. By the age of 2, children who are unable to use up to 270 one-word phrases and 25 different phonemes, not averaging 75 words per hour during free play, not able to talk in several two-to-three-word phrases with speech intelligibility or at least 65% ,and those who are unable to name common objects and pictures are predicted to most likely struggle and be diagnosed with expressive language disorder. In addition, it is also recommended to have a hearing test to diagnosis if the children's ability to communicate is altered by hearing problems. Since age vary on diagnosis, treatment varies as well.

Treatment
Treatment of expressive language disorder does not require medicine most of the time, but instead involves speech and language therapies. However, it is recommended to get a full physical check to rule out other possible disorders such as hearing loss. The recommended way to treat expressive language disorder is to work out a therapy plan by visiting a speech and language therapist. Some therapies may include use of toys, books, figures, and images to help improve the condition. In addition, parents could also aid children at home. For example, parents could have a small conversation with their children with slow, clear, and short words to gradually improve children's condition. In this process, patience is key, and it is also important to not make the children stressed. Additionally, let children repeat a short sentence or say it in their own words could also be helpful. Early diagnosis and treatment is really important to treat expressive language disorder.

Prognosis
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. This is tied into the inability to properly communicate or express language due to the plethora of functional impairments that come with this disorder. 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. 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. A variety of speech and language therapies which include the use of pictures, books, and much more have led to improvements in overall expression, encourages children to participate in many activities, helps them make more friends, and reduces the stress in parents and children. However, if the condition is not treated, it will cause the children to have a decreased performance in school and increased frustration in both the parents and children due to difficulties in communication. 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. Activities such as reading to the child or the introductions to new words on objects or signs, would be good examples.

Scientific studies of speech and language
Some of the earliest discoveries in the field of neuroscience were related to the discovery that damage to certain areas of the brain related to impairments in language, such as the discovery of Wernicke's area and Broca's area. Lesions in these parts of the brain impair language comprehension and language production, respectively. 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. Modern neuroscientific research has verified this, though language may be lateralized to the right hemisphere in some right-handed individuals..
