Brain And Aphasia
Transcortical Motor Aphasia, also known as commissural dysphasia or white matter dysphasia, results from damage to the language-dominant hemisphere in the anterior superior frontal lobe. Transcortical Motor Aphasia is classified as a non-fluent aphasia characterized by a significantly reduced speech output but good auditory comprehension.
Approach to the Patient with Aphasia Neupsy Key
Aphasia is a condition that has a connection or an overlap with several other speech-related disorders and problems, such as dysarthria, dysphasia and apraxia. Aphasia: This is the overall term for a brain-connected problem with language abilities, including speaking or understanding other people speaking.

Transcortical motor aphasia ( TMoA ), also known as commissural dysphasia or white matter dysphasia, results from damage in the anterior superior frontal lobe of the language-dominant hemisphere. This damage is typically due to cerebrovascular accident (CVA).

If an individual presents with non-fluent speech, they could potentially have Broca's, global, mixed transcortical, or transcortical motor aphasia. By contrast, if their speech was fluent, a clinician could surmise it to be Wernicke's, conduction, anomic, or sensory transcortical aphasia. During the diagnostic procedure, aphasic.

Transcortical motor aphasia. This type of aphasia closely mimics Broca's aphasia. TMA is due to a stroke or brain injury that impacts Broca's area in the brain but doesn't directly injure.

For this reason, mixed transcortical aphasia is characterized by a severely diminished quantity of spontaneously generated verbal output, very poor auditory comprehension, and relative sparing of repetition with echolalia. Practically, this type of aphasia combines symptoms of both transcortical motor and sensory aphasia.

Analysis of language profiles and CT anatomy in transcortical motor aphasia (TCMA) suggests that the essential lesion is disruption of connections at sites between the supplementary motor area and the frontal perisylvian speech zone.

Transcortical motor aphasia is a subtype of nonfluent aphasia in which repetition is preserved relative to impaired verbal output. Expressive language is effortful and halting, with disrupted prosody, paraphasic errors, and perseveration. Confrontation naming may be intact.

The defining symptoms of transcortical motor aphasia (TCMA) are nonfluent verbal output with relatively preserved repetition. Other symptoms, such as naming difficulties, agrammatic output, or even some paraphasias, may occur, but these are not cardinal symptoms defining TCMA and are not necessary for the diagnosis.

Transcortical Motor Aphasia is a type of non-fluent aphasia. This means that speech is halting with a lot of starts and stops. People with TMA typically have good repetition skills, especially compared to spontaneous speech. For instance, a person with TMA might be able to repeat a long sentence.

Transcortical motor aphasia resembles Broca's aphasia, but patients are able to repeat. The term transcortical aphasia was suggested by Wernicke in 1881 and Lichtheim in 1885. It was also termed anterior isolation syndrome by Benson and Geschwind.43 Verbal output is described as nonfluent and dysarthric, as in Broca's aphasia.

Memantine is an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist. Like Piracetam, the initial enthusiasm to evaluate the potential efficacy of memantine in post-stroke aphasia was prompted by the beneficial effects obtained with this drug in language and communication among patients with Alzheimer's disease ( ).

Aphasia is an impairment of comprehension or formulation of language caused by damage to the cortical center for language. It can be caused by many different brain diseases and disorders; however, cerebrovascular accident (CVA) is the most common reason for a person to develop aphasia.

Transcortical Sensory Aphasia (TSA) has a lot in common with Wernicke's aphasia. People with TSA produce connected, flowing speech. However, that speech is likely to lack meaning due to word errors and invented words. TSA is less common than other types of aphasia, including the similar Wernicke's aphasia.
