Expressive aphasia (also known as Broca's aphasia) is a type of aphasia characterized by partial loss of the ability to produce language (spoken, manual, [1] or written), although comprehension generally remains intact. [2] A person with expressive aphasia will exhibit effortful speech.
Unlike Wernicke's aphasia, which causes patients to speak fluently, but producing a jumbled mix of nonsensical words, people with Broca's aphasia speak slowly, and typically in small sentences, yet they are much more able to convey the intended meaning of the sentence.
Wernicke's area (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to Broca's area, which is primarily involved in the ...
Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] 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. [3]

Aphasia usually is a result of traumatic head injury or stroke, but can have other causes such as tumors or progressive diseases. [18] There are several types of aphasia, with the two most popular being Broca’s Aphasia and Wernicke’s Aphasia.
The discovery of what is now known as Broca's area was followed years later by Carl Wernicke's famous work, 'The Symptom-Complex of Aphasia: A Psychological Study on an Anatomical Basis' in 1874. This paper is regarded as one of the most influential works in the history of the field of aphasiology.
Damage to the Broca's area does not affect comprehension of speech. [8] Wernicke's aphasia is characterized by fluent language with made up or unnecessary words with little or no meaning to speech. Those who suffer from this type of aphasia have difficulty understanding others' speech and are unaware of their own mistakes.
Damage to Broca's area is commonly associated with telegraphic speech made up of content vocabulary. For example, a person with Broca's aphasia may say something like, "Drive, store. Mom." meaning to say, "My mom drove me to the store today." Therefore, the content of the information is correct, but the grammar and fluidity of the sentence is ...
