General Information on Broca’s aphasia

 

Broca’s aphasia is classified as a non-fluent aphasia.  It also can be known as expressive aphasia, motor aphasia, or anterior aphasia (Brookshire, 2003).  It is caused by damage of Broca’s area (Brodman’s areas 44 and 45) in the posterior-inferior frontal gyrus of the left hemisphere (Roseberry-McKibbin, 2000).  It also extends into the underlying white matter and involves the Insula and Basal Ganglia.
