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.
