As the disease develops, speech quantity decreases and many patients become mute. Cognitive domains other than language are rarely affected early on. However, as the disease progresses, other domains can be affected. Problems with writing, reading, and speech comprehension can occur, as can behavioural features similar to frontotemporal dementia.
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]
Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] The major causes are stroke and head trauma; prevalence is hard to determine, but aphasia due to stroke is estimated to be 0.1–0.4% in the Global North. [3]

To ward off dementia, older adults may want to spend more time reading, praying, crafting, listening to music and engaging in other mentally stimulating behaviors, a new study says.
Researchers have developed an AI tool that can predict with nearly 80% accuracy whether someone is at risk for developing Alzheimer’s disease based on their speech patterns.
It is suspected that an atypical form of Alzheimer's disease is the most common cause of logopenic progressive aphasia. [ 3 ] [ 4 ] Although patients with the logopenic variant of PPA are still able to produce speech, their speech rate may be significantly slowed due to word retrieval difficulty. [ 4 ]
