	[[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, or written), although comprehension generally remains intact. It is caused by damage to the posterior part of the frontal lobe of the brain, which includes Broca's area.

	== Definition and Overview ==		== Definition and Overview ==

	Expressive aphasia is a non-fluent aphasia that results from damage to the frontal lobes of the brain, especially the left frontal lobe. Despite having clear thoughts and ideas, individuals with expressive aphasia struggle to articulate their thoughts effectively in spoken or written form. They typically understand spoken language well, and can read adequately, but find it difficult to speak and write because they can't form sentences correctly.

	Expressive aphasia is most commonly caused by stroke, but can also result from head injury, brain tumor or other neurological disorders that affect language-processing areas of the brain, especially Broca's area. Risk factors for these conditions, such as high blood pressure, smoking, and old age, can therefore also increase the risk of expressive aphasia.

	== Symptoms ==		== Symptoms ==

	The primary symptom of expressive aphasia is difficulty forming complete sentences. Speech is typically slow and laborious, and individuals may struggle with word-finding issues. Writing ability is similarly affected. However, people with expressive aphasia are usually able to understand speech and read text well, and they are typically aware of their difficulties, which can lead to frustration.

	Diagnosis of expressive aphasia is typically made through a detailed clinical evaluation that includes medical history, neurological examination, and language tests.

	Treatment for expressive aphasia usually involves speech and language therapy, where a therapist works with the individual to improve their language skills and use alternative methods of communication.
