Expressive aphasia, also known as Broca's aphasia, is a language disorder caused by damage to the brain's frontal lobe. The person with expressive aphasia has difficulty expressing themselves verbally and often struggles with word formation and sentence structure. There are several synonyms for the term expressive aphasia, including non-fluent aphasia, motor aphasia, and agrammatic aphasia. These terms refer to the same condition as expressive aphasia, but highlight different aspects of the language impairment. It is important to note that these terms are used interchangeably by healthcare professionals and individuals to describe the language disorder caused by damage to the brain's frontal lobe.
