Paraphasia
Paraphasia
Paraphasia (/pærəˈfeɪziə/; from Greek para, "beside" + phasis, "speech") is a speech disturbance characterized by the production of unintended syllables, words, or phrases during the effort to speak. Paraphasias are commonly associated with aphasia and other language disorders.
Types of Paraphasia
There are two main types of paraphasia: phonemic and semantic.
- Phonemic paraphasia involves the substitution, addition, or rearrangement of sounds in a word. For example, a person might say "tup" instead of "cup."
- Semantic paraphasia involves the substitution of one word for another. For example, a person might say "chair" when they mean to say "table."
Causes
Paraphasia is often caused by damage to the brain, particularly the left hemisphere, which is responsible for language in most right-handed individuals. This damage can occur due to a stroke, brain tumor, traumatic brain injury, or a neurological disorder such as Alzheimer's disease or dementia.
Treatment
Treatment for paraphasia typically involves speech and language therapy. The goal of speech therapy is to help the individual improve their ability to communicate by restoring as much language function as possible and teaching them how to compensate for language difficulties.
