Broca's aphasia

from Wikipedia, the free encyclopedia
Human brain (from left). The Broca area (language production), together with the Wernicke area (language understanding), is regarded as one of the two main components of the language center .

The expressive aphasia is named after the French neurologist Paul Broca called aphasia (language disorder), in which mainly the speech production is affected.

Emergence

There is usually extensive damage to the frontal cortex in Broca's aphasia.

Effects

Classification according to ICD-10
R47.0 Dysphasia and aphasia
ICD-10 online (WHO version 2019)

The language of Broca aphasic people seems superfluous and very shortened - like in the telegram style.

The word finding is cumbersome and delayed in these aphasic patients often are phonemic Paraphrasien (phonetic changes of words such as / Jegan / for "Left") used.

The use of morphology and syntax is also disturbed, which greatly shortens sentence structure and grammar ( agrammatism )

In this language disorder, however, speech understanding is often largely preserved. However, the understanding of more complex sentence structures (sentence embedding, passive constructions, preferred objects), for which the meaning can only be deduced from functional words (e.g. "This pit bull bit my German shepherd!"), May be limited. The relatively well-preserved understanding of language often means that patients with Broca's aphasia have a pronounced awareness of the disorder and suffer greatly from their disorder.

Deaf patients with Broca's aphasia also produce superfluous, agrammatic sign language.
