A speech-language pathologist (SLP) is a highly-trained professional who evaluates and treats children and adults who have difficulty with speech or language. Although people often think of speech and language as the same thing, the terms actually have very different meanings.
Speech-language pathologists (SLPs) work to prevent, assess, diagnose and treat speech, language, social communication, cognitive-communication and swallowing disorders in children and adults.
Speech disorders occur when a person has difficulty producing speech sounds correctly or fluently (e.g., stuttering is a form of disfluency) or has problems with his or her voice or resonance.
Language disorders occur when a person has trouble understanding others (receptive language), or sharing thoughts, ideas, and feelings (expressive language). Language disorders may be spoken or written and may involve the form (phonology, morphology, syntax), content (semantics), and/or use (pragmatics) of language in functional and socially appropriate ways.
Social communication disorders occur when a person has trouble with the social use of verbal and nonverbal communication. These disorders may include problems (a) communicating for social purposes (e.g., greeting, commenting, asking questions), (b) talking in different ways to suit the listener and setting, and (c) following rules for conversation and story-telling. All individuals with autism spectrum disorder have social communication problems. Social communication disorders are also found individuals with other conditions, such as traumatic brain injury.
Cognitive-communication disorders include problems organizing thoughts, paying attention, remembering, planning, and/or problem-solving. These disorders usually happen as a result of a stroke, traumatic brain injury, or dementia, although they can be congenital.
Swallowing disorders (dysphagia) are feeding and swallowing difficulties, which may follow an illness, surgery, stroke, or injury.
