What are the "nonsense" words typical of Wernicke's aphasia called?

The term "neologisms" refers to the creation of new, nonsensical words that individuals with Wernicke's aphasia often produce. In this condition, people have fluent speech and maintain normal grammatical structure, but the words they use may lack meaning or be entirely invented. This indicates a breakdown in the ability to retrieve appropriate vocabulary, leading to the substitution of real words with entirely new terms that do not exist in the language.

While jargon typically describes a type of expressive speech that sounds fluent but may be filled with meaningful context only to the speaker, neologisms specifically refer to the newly created words that do not have an established meaning. This characteristic of Wernicke’s aphasia highlights the difficulties in language comprehension and production that individuals experience, showcasing the complexity of language processing in the brain.
