The muscles of the tongue, lips, jaw and vocal tract coordinate the action of producing recognizable sounds that we call language. Communication Disorders begin to gain speech and language skills in infancy, when we learn that crying can produce needs like food or attention.
Within a short time, we sort what we hear into speech sounds and begin to learn and understand language. This begins well before we speak. The first three years of life are crucial for acquiring language. In situations where this exposure and interaction do occur, the effect on our ability to communicate can last a lifetime. The lifetime effect of communication disorders is supported by research into the correlation between language disorders and unemployment.

The rate of unemployment for individuals with speech disorder, in particular, stood at between 67 and 76 percent. People with expressive language disorder will either speak rarely or use language that is conspicuously less complex that than of their peers. They may rely on gesturing instead of verbal speech. Expressive language disorder can occur at any time during childhood as the effect of a trauma or a neurological disorder. How prevalent is expressive language disorder?
Expressive language disorder is relatively uncommon. Three to five percent of school age children are diagnosed as having an expressive language disorder, two to three times as many boys as girls. A phonological disorder causes mistakes in sound production, the substitute of one sound for another, or sounds such as final consonants are left out. Accurate information about the prevalence of phonological disorder is scarce. However, experts estimate that 10 percent of children under the age of 8 and 5 percent over that age are diagnosed with this disorder. Boys are two to three times more likely to show the symptoms of phonological disorder than are girls. Stuttering consists of sound repetitions, prolongations, pauses within words and word substitutions to avoid blocking.
Sometimes, no sound at all is made. Stuttering can occur more frequently in certain situations or with certain words or sounds. At one time, it was believed that stuttering was caused by a psychological disturbance. This theory has given way to the idea that the basis of stuttering lies in the incomplete use of both halves of the brain or a cerebral abnormality, while other experts believe that it’s a learned response to certain stimuli. The actual cause is most probably a combination of factors that include genetics and environment. It can become chronic in the elementary school years, while, after the age of 8 and through early adolescence, stuttering comes and goes in response to certain situations or stressors.
Carly Simon, and actors Samuel L Jackson and Bruce Willis have all struggled with this disorder. What treatments are available for communication disorders? Recovery from phonological disorder is usually spontaneous and does not require intervention. However, effective treatment for the other communication disorders is available and can be crucial to the development and psychological well being of the child.
Language problems can cause a child to have a poor self-image, become frustrated or develop depression. Treatment for stuttering is based on the idea that it is a learned form of behavior and includes encouraging the person to overcome their fear and speak, even if that means that they will stutter. The Stuttering Foundation of America offers these suggestions for both parents and teacher of children who stutter. Keep eye contact and give the child enough time to finish speaking. Try not to fill in words or sentences. Where can I find help with communication disorders?

A communication disorder is any disorder that affects an individual’s ability to comprehend, detect, or apply language and speech to engage in discourse effectively with others. The delays and disorders can range from simple sound substitution to the inability to understand or use one’s native language.
Something On My Mind
Disorders and tendencies included and excluded under the category of communication disorders may vary by source. The delays and disorders can range from simple sound substitution to the inability to understand or use their native language. Persons who speak more than one language or are considered to have an accent in their location of residence do not have speech disorders if they are speaking in a manner consistent with their home environment or a blending of their home and foreign environment. According to the DSM-IV-TR, communication disorders are usually first diagnosed in childhood or adolescence though they are not limited as childhood disorders and may persist into adulthood. They may also occur with other disorders.

This assessment may also determine if the characteristic is deviant or delayed. It should also be noted that the DSM diagnoses do not comprise a complete list of all communication disorders, for example, auditory processing disorder is not classified under the DSM or ICD-10. Characterized by difficulty expressing oneself beyond simple sentences and a limited vocabulary. DSM-IV diagnosis in which disorders that do not meet the specific criteria for the disorder listed above may be classified. The DSM-5 diagnoses for communication disorders completely rework the ones stated above. The important characteristics of language disorder are difficulties in learning and using language, which is caused by problems with vocabulary, with grammar, and with putting sentences together in a proper manner. The difference between this diagnosis and autism spectrum disorder is that in the latter there is also a restricted or repetitive pattern of behavior.
SLI is also called developmental language disorder, language delay, or developmental dysphasia. A link between communication skills and visual impairment with children who are blind is currently being investigated. Trouble with hearing during language acquisition may lead to spoken language problems. Children who suffer from frequent ear infections may temporarily develop problems pronouncing words correctly. It should also be noted that some of the above communication disorders can occur with people who use sign language.

Aphasia is loss of the ability to produce or comprehend language. There are acute aphasias which result from stroke or brain injury, and primary progressive aphasias caused by progressive illnesses such as dementia. A person with expressive aphasia usually speaks in short sentences that make sense but take great effort to produce. Also, a person with expressive aphasia understands another person’s speech but has trouble responding quickly. Receptive aphasia also known as Wernicke’s aphasia, receptive aphasia is a fluent aphasia that is categorized by damage to the temporal lobe region of the brain. A person with receptive aphasia usually speaks in long sentences that have no meaning or content. People with this type of aphasia often have trouble understanding other’s speech and generally do not realize that they are not making any sense.
Usually learnt and used by patients who cannot use their larynges to speak. Once the patient has forced the air into their esophagus, the air vibrates a muscle and creates esophageal voice. Esophageal voice tends to be difficult to learn and patients are often only able to talk in short phrases with a quiet voice. Expressive Language Disorder – ICD 315.

Swearing Can Enhance Your Pain Tolerance! Many children have speech or language disorders—including difficulty with word articulation, written language, and interacting with the social rules of verbal and nonverbal communication. Early intervention is the key to successful treatment. Definition Communication disorders include problems related to speech, language, and communication.
Speech refers to the production of sounds that allow individuals to express themselves, and includes articulation, fluency, voice, and resonance quality. Communication disorders may range from simple sound repetitions such as stuttering to occasional misarticulation of words to complete inability to use speech and language for communication. Speech is produced by precise, coordinated muscle actions in the head, neck, chest, and abdomen. Speech development is a gradual process that requires years of practice. During speech development, one learns how to regulate these muscles to produce intelligible speech. It is estimated that by the first grade, five percent of children have noticeable speech disorders, the majority of which have no known cause.

One category of speech disorder is dysfluency, which is the disruption of the flow of speech by repeating sounds or words, prolonging sounds, or becoming silent. Articulation difficulties are commonly found in people who have speech disorders. The term refers to problems forming and combining sounds, usually by omitting, distorting, or substituting them. People with voice disorders may have trouble with the way their voices sound. Listeners may have trouble understanding someone with this speech pathology. Language is the expression of human communication through which knowledge, beliefs, and behavior can be experienced, explained, and shared. Disorders of language affect children and adults differently.
For children who do not use language normally from birth, or who acquire the impairment in childhood, the disorder occurs in the context of a language system that has not been not fully developed or acquired. Many adults acquire disorders of language because of stroke, head injury, dementia, or brain tumors. Auditory processing is the term used to describe what happens in your brain when it recognizes and interprets the sounds around you. Humans hear energy, which we recognize as sound when it travels through the ear and is changed into electrical impulses that can be interpreted by the brain. Children with APD often do not recognize subtle differences between sounds in words, even though the sounds themselves are loud and clear. For example, the request “Tell me how a couch and a chair are alike” may sound to a child with APD like “Tell me how a cow and a chair are alike.
It can even be understood by the child as “Tell me how a cow and a hair are alike. APD goes by many other names. Other common names are auditory perception problem, auditory comprehension deficit, central auditory dysfunction, central deafness, and so-called word deafness. APD is not universally recognized as a clinical condition, and it is not included in the DSM-5. Causes Some causes of communication disorders include hearing loss, neurological disorders, brain injury, vocal cord injury, autism, intellectual disability, drug abuse, physical impairments such as cleft lip or palate, emotional or psychiatric disorders, and developmental disorders. Frequently, however, the cause is unknown.

Call your health care provider if impairment or loss of communication comes on suddenly or there is any unexplained impairment of speech or written language. Treatments The best way to approach treatment for a communication disorder is to focus on prevention and early intervention. Parents should be aware of the typical age their child should be reaching each developmental milestone. This begins in the first few months of life with cooing—a quiet, pleasant, repetitive vocalization. By 6 months, an infant usually babbles or produces repetitive syllables such as “ba, ba, ba” or “da, da, da.
By the end of their first year, most children have mastered the ability to say a few simple words. By 18 months of age, most children can say eight to ten words. By age 2, most are putting words together in crude sentences such as “more milk. During this period, children rapidly learn that words symbolize or represent objects, actions, and thoughts. At ages 3, 4, and 5, a child’s vocabulary rapidly increases, and she or he begins to master the rules of language. If you have concerns about your child’s speech or language development, you should talk to your family doctor. Your doctor may refer you to a speech-language pathologist, a health professional trained to evaluate and treat people who have speech, language, voice, hearing, or swallowing disorders that affect their ability to communicate.

A hearing test is often included in the evaluation because a hearing problem can affect speech and language development. Depending on the test results, the speech-language pathologist may suggest at-home activities to stimulate speech and language development. For example, if your child says, “Ball baybo” you can respond with, “Yes, the ball is under the table. The speech-language pathologist may also recommend group or individual therapy, or suggest further evaluation by other health professionals such as an audiologist or a developmental psychologist. Expressive language disorder identifies developmental delays and difficulties in the ability to produce speech. Mixed receptive-expressive language disorder identifies developmental delays and difficulties in the ability to understand spoken language and produce speech.
Communication disorders may be developmental or acquired. The cause may be related to biological problems such as abnormalities of brain development, or possibly by exposure to toxins during pregnancy, such as abused substances or environmental toxins such as lead. A genetic factor is sometimes considered a contributing cause in some cases. Who is affected by communication disorders? For unknown reasons, boys are diagnosed with communication disorders more often than girls. Children with communication disorders frequently have other psychiatric disorders as well. What are the symptoms of communication disorders?
The following are the most common symptoms of communication disorders. However, each child may experience symptoms differently. Young children with communication disorders may not speak at all, or may have a limited vocabulary for their age. Some children with communication disorders have difficulty understanding simple directions or are unable to name objects. Most children with communication disorders are able to speak by the time they enter school, however, they continue to have problems with communication. School-aged children often have problems understanding and formulating words. Teens may have more difficulty with understanding or expressing abstract ideas.
The symptoms of communication disorders may resemble other problems or medical conditions. Always consult your child’s doctor for a diagnosis. Most children with communication disorders are first referred for speech and language evaluations when their delays in communicating are noted. A child psychiatrist is usually consulted, especially when emotional or behavioral problems are also present. Remedial techniques are used to increase communication skills in the areas of the deficit.
A second approach helps the child build on his or her strengths to circumvent his or her communication deficit. Prevention of communication disorders Specific preventive measures to reduce the incidence of communication disorders are not known at this time. However, early detection and intervention can address the developmental needs and academic difficulties to improve the quality of life experienced by children with communication disorders.

A voice disorder exists when the voice’s quality, pitch, or volume differs from that of other persons of similar age, culture, and geographic location. Dysphonia is classified as either an organic or a functional disorder of the larynx. Another type of communication problem, dysarthria, encompasses a group of motor speech disorders caused by a disturbance in the neuromuscular control of speech. A second form of motor speech disorder, apraxia, occurs in the presence of significant weakness or incoordination of the muscles of speech production.

Aphasia is a language disorder that results from damage to the areas of the brain responsible for language comprehension and expression, while a cognitive-communicative disorder affects the ability to communicate by impairing the pragmatics, or social rules, of language. Through communication, people are able to express thoughts, needs, and emotions. Communication is an intricate process that involves cerebration, cognition, hearing, speech production, and motor coordination. Language is the transformation of thoughts into meaningful symbols communicated by speech, writing, or gestures. Thoughts are organized by the brain, specifically the left hemisphere, and encoded into a sequence according to learned grammatic and linguistic rules. Speech production Speech involves the coordinated motor activity of muscles involved in respiration, phonation, resonance, and articulation.
The entire system is modulated by central and peripheral innervation, including with cranial nerves V, X, XI, and XII, as well as with the phrenic and intercostal nerves. Respiratory muscles, specifically the muscles associated with expiration, must generate enough air pressure to provide adequate breath support to make speech audible. Phonatory muscles of the larynx generate vibratory energy during vocal cord approximation to produce sound. Vocal pitch and intensity are modified by subglottic air pressure, tension of the vocal cords, and position of the larynx. Articulatory muscles within the pharynx, mouth, and nose form the tone of the sound.
The coordinated action of these muscles produces speech. By altering the shape of the vocal tract, we are capable of producing a tremendous range of sounds. Sound waves are transformed by the auditory system into neural input for the speaker and the listener. The outer ear detects sound-pressure waves in the air and converts them into mechanical vibrations in the middle and inner ear.

The cochlea then transforms these mechanical vibrations into vibrations in fluid, which act on the nerve endings of the eighth cranial nerve. Thus, the process of communication begins and ends in the brain. Voice is the audible sound produced by passage of air through the larynx. A voice disorder exists when the quality, pitch, or volume differs from that of other persons of similar age, culture, and geographic location. Organic dysphonia Organic disorders cause an interruption in the smooth approximation of the vocal folds. Functional dysphonia Functional disorders affect the quality and volume of the voice.
A study of 162 teachers with behavioral dysphonia suggested that a 6-week course of vocal function exercises can prevent one out of three cases of dysphonia aggravation, as compared with prevention of one out of five cases using a voice amplifier. Diagnosis and referral Rule out a treatable medical condition in all patients with voice disorders. For example, a voice disorder may be one of the first symptoms of laryngeal cancer. The SLP helps the patient to produce the most functional voice possible.
Laryngectomy rehabilitation Laryngectomy remains a common procedure for the treatment of laryngeal cancer. Options for the restoration of speech following laryngectomy patient are detailed below. Esophageal speech is accomplished by training the patient to suck air into the esophagus, hold the air, and then release it in a controlled manner through the oral cavity. Disorders of motor speech are classified into dysarthrias and apraxias. Dysarthria The term dysarthria encompasses a group of motor speech disorders caused by a disturbance in the neuromuscular control of speech.
