Pure word deafness is a rare behavioral disorder in which the comprehension of spoken language is grossly disturbed, but the abilities to speak, read, write, and process nonverbal auditory stimuli remain intact.
What language disorder involves pure word deafness?
Auditory verbal agnosia (AVA), also known as pure word deafness, is the inability to comprehend speech. Individuals with this disorder lose the ability to understand language, repeat words, and write from dictation.
What is Transcortical sensory aphasia?
Transcortical sensory aphasia (TSA) is characterized by impaired auditory comprehension with intact repetition and fluent speech. We induced TSA transiently by electrical interference during routine cortical function mapping in six adult seizure patients.
What does Broca aphasia mean?
Broca’s dysphasia (also known as Broca’s aphasia) It involves damage to a part of the brain known as Broca’s area. Broca’s area is responsible for speech production. People with Broca’s dysphasia have extreme difficulty forming words and sentences, and may speak with difficulty or not at all.
What part of the brain is damaged in pure word deafness?
Pure Word Deafness and Language When pure word deafness is due to a stroke, it results from damage to both the nerve fibers that connect the part of the brain that processes hearing (primary auditory cortex) and the part of the brain that processes language (the association areas of the superior temporal lobe).
Can people with word deafness hear?
In pure word deafness (auditory agnosia) the auditory comprehension of language is lost, although the ability to hear other sounds is relatively intact. Speech output, reading, and writing are relatively unaffected.
What is the difference between agnosia and aphasia?
Persons with Wernicke’s aphasia also have troubles understanding speech but the underlying causes are different from those in agnosia and usually they recognize speech sounds as such (see Wernicke’s aphasia). In visual agnosia, patients cannot recognize objects.
What is jargon aphasia?
The production of incomprehensible language containing frequent phonemic distortions, semantic errors or neologisms secondary to neurological disease has been termed jargon aphasia (or if writing is affected, jargon agraphia).
What is meant by aphasia?
Aphasia is a disorder that results from damage to areas of the brain that produce and process language. A person with aphasia can have trouble speaking, reading, writing, and understanding language. Impairment in these abilities can range from mild to very severe (nearly impossible to communicate in any form).
How do you identify sensory aphasia?
Transcortical sensory aphasia (TSA) is characterized by impaired auditory comprehension, with intact repetition and fluent speech (Lichtheim, 1885; Goldstein, 1948). The sparing of repetition distinguishes TSA from other receptive aphasias and agnosias, including Wernicke’s aphasia and pure word deafness.
What are the symptoms of Transcortical sensory aphasia?
Transcortical sensory aphasia (TSA) is a kind of aphasia that involves damage to specific areas of the temporal lobe of the brain, resulting in symptoms such as poor auditory comprehension, relatively intact repetition, and fluent speech with semantic paraphasias present.
Can people with Transcortical sensory aphasia read?
Sensory aphasia is caused by damage to the parts of the temporal lobe that surround Wernicke’s area. Other symptoms of transcortical sensory aphasia include: Reading difficulties.
What are the 3 types of aphasia?
The three kinds of aphasia are Broca’s aphasia, Wernicke’s aphasia, and global aphasia. All three interfere with your ability to speak and/or understand language.
How would you treat someone with Broca’s aphasia?
Currently, there is no standard treatment for Broca’s aphasia. Treatments should be tailored to each patient’s needs. Speech and language therapy is the mainstay of care for patients with aphasia. It is essential to provide aphasic patients a means to communicate their wants and needs, so these may be addressed.
Can a person recover from aphasia?
Can You Recover From Aphasia? Yes. Aphasia is not always permanent, and in some cases, an individual who suffered from a stroke will completely recover without any treatment. This kind of turnaround is called spontaneous recovery and is most likely to occur in patients who had a transient ischemic attack (TIA).

The affected individuals remain capable of spelling and writing words and sentences but are unable to comprehend what was written by themselves. This is differentiated from the mechanical inability to read, such as …
What happens when Heschl’s gyrus is damaged?
Bilateral temporoparietal lesions (Heschl gyrus, areas 41, 42) can cause cortical deafness and language impairment . But when there is lesion in subcortical structures like projection fibres from medial geniculate bodies or colliculi to auditory cortices, there are deafness and dysarthria.
What is Agraphia disorder?
Agraphia is the loss of a previous ability to communicate in writing. It can be caused by: traumatic brain injury. stroke. health conditions such as dementia, epilepsy, or brain lesions.
What is nominal aphasia?

What is Wernicke aphasia?
Aphasia is an impairment of language function which is localized to the dominant cerebral hemisphere. Wernicke aphasia is characterized by impaired language comprehension. Despite this impaired comprehension, speech may have a normal rate, rhythm, and grammar.
What is isolation aphasia?
Mixed transcortical aphasia, or isolation aphasia, is equivalent to global aphasia with preserved repetition. 47. Patients with this syndrome do not speak unless spoken to, and their verbal output is almost entirely limited to what has been offered by the examiner—a true echolalia.
What are the 4 A’s of dementia?
The four A’s of Alzheimer’s disease are: amnesia, aphasia, apraxia, and agnosia.
What are the 7 A’s of dementia?

Does agnosia affect memory?
Symptoms include the inability to recognize familiar places or buildings. Affected individuals may be able to describe a familiar environment from memory and point to it on a map. Primary agnosia is associated with bilateral damage to the ventral visual stream, including the lingual and fusiform gyri.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
