Patients with Wernicke's aphasia demonstrate fluent speech, which is characterized by typical speech rate, intact syntactic abilities and effortless speech output. [3] Writing often reflects speech in that it tends to lack content or meaning. In most cases, motor deficits (i.e. hemiparesis) do not occur in individuals with Wernicke's aphasia. [4]
Typically, people with expressive aphasia can understand speech and read better than they can produce speech and write. [8] The person's writing will resemble their speech and will be effortful, lacking cohesion, and containing mostly content words. [15] Letters will likely be formed clumsily and distorted and some may even be omitted.
It is defined clinically by impairments in naming and sentence repetition. [2] It is similar to conduction 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. [3] [4]
Alzheimer's disease is related to semantic dementia, which both have similar symptoms. The main difference between the two being that Alzheimer's is categorized by atrophy to both sides of the brain while semantic dementia is categorized by loss of brain tissue in the front portion of the left temporal lobe.

It is less severe than logorrhea and may be associated with the middle stage in dementia. [1] It is, however, more severe than circumstantial speech, in which the speaker wanders but eventually returns to the topic. [3] Some adults with right hemisphere brain damage may exhibit behavior that includes tangential speech. [4]
It is the story of Hale's husband, John Hale, a scholar who had had a stroke and lost speech formation abilities. In her book, Hale also explains the symptoms and mechanics behind aphasia and speech formation. She adds the emotional components of dealing with a person with aphasia and how to be patient with the speech and communication. [35] [36]
