Having a right limb hemiparesis is common with left MCA territory lesions which can also result in nonfluentBroca ' stype aphasia because with large territory infarcts like this the motor strip in the frontal cortex is often affected . But this is too simplistic , and site of lesion does not always determine type of deficit . So yes , it is very possible to have just aphasia and no motor or sensory deficits if the motor areas of the brain were not affected . In fact I just did an initial assessment in the hospital yesterday with a young woman who suffered several embolic infarcts in the left frontal and parietal lobes and her only deficit appears to be language significant anomia , some mild receptive difficulties . No limb weakness or other motorsensory issues . Language is distributed across the brain so it is very possible just to have language impairments alone after a stroke . However , like I said it is relatively common to see an associated hemiparesishemiplegia with the L MCA strokes , which themselves are fairly common because of the organization of blood supply to the brain . Another thought is primary progressive aphasia , thought to be a form of dementia , that results in language deficits without necessarily any motor symptoms .
