"The pattern of atrophy in semantic dementia is relatively characteristic and helps distinguish these patients from those with Alzheimer's disease although there is considerable overlap with other primary progressive aphasias including logopenic dementia (which is an Alzheimer variant). Features include 1-3:"
"The main clinical differential (early on) is that of Alzheimer's disease, and a number of features on imaging are helpful."

"Diagnostic criteria"
"Patients with semantic dementia typically present with a gradual worsening of both expressive and receptive language function. Patients complain of difficulty in remembering the names of places, people or objects or attributing the correct function to named objects 2,3."
"Speech fluency is typically preserved but associated anomia leads to the common clinical ascription of "fluent empty speech". Patients will often also exhibit dyslexia, dysgraphia and difficulty recognising faces or objects 2."
