Patients with fluent aphasia (melodious, effortless, well-articulated speech, which may have little content) tend to have posterior lesions in the left hemisphere, whereas patients with non-fluent aphasia (effortful, poorly-articulated speech, with more accurate content than speech sounds) tend to have anterior lesions in the brain.

With Severe Wernicke’s Aphasia, his speech was approximately 40% understandable to untrained listeners due to neologisms (nonsense words) and paraphasias (mistakes that sound similar to the word). Non-fluent aphasias encompass the regions anterior to the central sulcus: Transcortical motor aphasia with difficulty in initiating and organising responses, but relatively preserved repetition, Mixed transcortical aphasia in which echolalia (repetition) is the only preserved language skill.

Like most people with Wernicke’s aphasia, he was not aware of his speech errors, but he could tell sometimes that people weren’t understanding him. Individuals with Broca aphasia often have difficulty understanding syntactically complex or semantically reversible sentences (e.g., "touch your nose after you touch your foot") but have little trouble understanding simple, semantically nonreversible sentences. http://www.ncbi.nlm.nih.gov/pubmed/19004769?tool=bestpractice.com, Dorsal stream: a stream of processing that supports the interface between sensory-phonologic networks and motor-articulatory networks ("sound to speech"), from Heschl gyrus bilaterally through left supramarginal gyrus and inferior frontal gyrus.

Treatment should be individualized to address the person's residual deficits, communicative needs and priorities, and available resources. It is typically characterised by errors in word retrieval or selection, including: Semantic paraphasias (substituting a semantically related word for a target word, e.g., calling a horse a cow), Phonemic paraphasias (substituting one or more sounds in the word, e.g., calling a horse a force or using a non-word such as porse), Neologisms (a series of sounds that do not comprise a word and are not similar to the target word).
