- "In aphasia (sometimes called dysphasia), a person may be unable to comprehend or unable to formulate language because of damage to specific brain regions. The major causes are stroke and head trauma; prevalence is hard to determine but aphasia due to stroke is estimated to be 0.1–0.4% in the Global North."
The study of language impairments, such as aphasia, and their underlying causes.
Introduction to Psycholinguistics: This topic gives an overview of psycholinguistics and its importance in understanding language disorders.
Language Acquisition: Language acquisition refers to the process of learning language and how language develops in children.
Linguistic Competence and Performance: This topic explores the difference between linguistic competence (the knowledge of language) and linguistic performance (the actual use of language).
Language Processing: This topic covers a range of processes involved in language comprehension and production.
Language Disorders: This topic provides an overview of various types of language disorders, including developmental language disorders and acquired language disorders.
Speech Disorders: This topic explores different types of speech disorders, including apraxia of speech, dysarthria, and stuttering.
Language Assessment: This topic covers the process of evaluating language skills to identify deficits in language functioning.
Intervention and Treatment: This topic focuses on the strategies and techniques used to treat language disorders.
Neurological Bases of Language: This topic explores the neurological mechanisms underlying language processing and disorders.
Cultural and Bilingual Issues in Language Disorders: This topic focuses on the impact of cultural and linguistic diversity on the assessment and treatment of language disorders.
Aphasia: It is a language disorder characterized by the inability to comprehend and produce language due to brain damage. Aphasia can affect speaking, listening, reading, and writing abilities.
Dyslexia: A learning disability that affects reading ability, spelling, and comprehension. Dyslexia often makes it challenging to distinguish between letters and numbers.
Apraxia of speech: It is a motor speech disorder that affects the ability to plan and coordinate the movements required to produce speech sounds.
Specific Language Impairment (SLI): A disorder that affects language development in children. Children with SLI have difficulty understanding and using language, despite having typical cognitive and physiological development.
Stuttering: A speech disorder where the flow of speech is disrupted by frequent repetitions or pauses. Stuttering can affect the individual's fluency, timing, and rhythm while speaking.
Language delay: A condition where children develop their language skills later than expected. Language delay can cause problems with communication, cognitive development and social interaction.
Semantic-Pragmatic Disorder: A disorder that affects a child's understanding and use of language in social communication. Children with SPD may have difficulty understanding non-verbal cues.
Asperger's Syndrome: This is a high-functioning form of autism where individuals may have difficulty with communication, especially in social situations.
Global Aphasia: A severe form of aphasia where an individual loses the ability to understand, speak, read, and write language.
- "To be diagnosed with aphasia, a person's language must be significantly impaired in one (or more) of the four aspects of communication." - "The four aspects of communication are spoken language production and comprehension, and written language production and comprehension."
- "The difficulties of people with aphasia can range from occasional trouble finding words, to losing the ability to speak, read, or write; intelligence, however, is unaffected."
- "Expressive language and receptive language can both be affected as well." - "Aphasia also affects visual language such as sign language."
- "In contrast, the use of formulaic expressions in everyday communication is often preserved."
- "One prevalent deficit in the aphasias is anomia, which is a difficulty in finding the correct word."
- "Aphasia is not caused by damage to the brain that results in motor or sensory deficits, which produces abnormal speech; that is, aphasia is not related to the mechanics of speech but rather the individual's language cognition."
- "An individual's language is the socially shared set of rules, as well as the thought processes that go behind communication."
- "It is not a result of a more peripheral motor or sensory difficulty, such as paralysis affecting the speech muscles or a general hearing impairment."
- "Neurodevelopmental forms of auditory processing disorder are differentiable from aphasia in that aphasia is by definition caused by acquired brain injury, but acquired epileptic aphasia has been viewed as a form of APD."
