Primary progressive aphasia: misdiagnosis with ‘normal imaging’

Aphasia, an acquired disorder of language function, has a potentially broad differential diagnosis. We present two cases in which primary progressive aphasia in its most common variant – the non‐fluent form – was misdiagnosed as other cognitive disorders, with consequent implications for patient lifestyle and activities. Greater awareness of this disorder is required in the assessment of patients presenting to memory clinics.
