- Main article: Aphasia
Logopenic progressive aphasia (LPA) is a form of primary progressive aphasia characterized by slow speech and impaired syntactic comprehension and naming. It is similar to receptive aphasia and is associated with atrophy to the left posterior temporal cortex and inferior parietal lobule. It is suspected that an atypical form of Alzheimer's disease is the most common cause of logopenic progressive aphasia.
Although patients with this the logopenic variant of PPA are still able to produce speech, their speech rate may be significantly slowed down due to word retrieval difficulty. Over time, they may experience the inability to retain lengthy information, causing problems with understanding complex verbal information.
A distinguishing symptom is a repetition of spared and impaired language processes seen in logopenic patients in comparison to patients suffering from other forms of progressive aphasia. Difficult in naming and repeating in motor speech, semantic, and syntactic abilities is one such specific challenge faced by patients of this disorder.
