Researchers at Henry Ford Hospital found that a 40-year-old man's inability to write coherent text messages was a key symptom of an acute ischemic stroke. The study highlights the potential use of dystextia as a diagnostic tool, particularly for patients with no other clear symptoms.
Researchers at Northwestern University have made significant breakthroughs in understanding the effects of brain damage on language processing and recovery. Studies have shown that with targeted training, patients can regain speech abilities years after a stroke.
Aphasia affects 80,000 people annually in the US, causing difficulty speaking and understanding language. Researchers at Brown University have developed a therapy to strengthen speech networks using guided speech and repetition exercises. Early testing with four patients showed improved precision and reduced errors.
Researchers investigate patterns of dysgraphia in participants with primary progressive aphasia, comparing them to those with stroke-related dysgraphia. They also explore nonverbal semantic processing in individuals with semantic aphasia and dementia, shedding light on brain-behavior relationships.
A study published in Brain and Language found that six weeks of intensive language therapy improved naming objects and cognitive potential in seniors with chronic aphasia. The therapy also integrated the default mode network, a brain system involved in 'on standby' activity, suggesting long-term recovery potential.
A survey in southern Ontario found that only 2% of respondents could correctly identify aphasia as a communication disorder affecting speaking, reading, writing and understanding. This highlights the need for increased awareness and access to speech-language therapy and supportive programs for people living with chronic aphasia.
Researchers found that singing complete texts was not decisive for patients with non-fluent aphasia. Rhythm and familiar song lyrics were more important for articulation. Daily expressions like 'How are you?' can be easier to articulate, regardless of whether sung or spoken.
MyVoice, a mobile app and server system, introduces location-aware vocabulary that suggests useful words and phrases based on a user's location. The device is dramatically more affordable than traditional speaking aids, with a $30-monthly subscription cost.
Researchers are developing a computer-based system to help stroke survivors with aphasia learn gestures independently, using motion sensing technologies like Nintendo Wii Remote. The project aims to create an affordable and accessible tool for therapy, addressing the limited resources and high cost of traditional one-to-one sessions.
A UCF study will interview and observe over 360 native Cantonese speakers with aphasia to create a database of linguistic symptoms and non-verbal behaviors. The research aims to improve assessment methods and treatment guidelines for Chinese speakers worldwide.
A study by Gerry Stefanatos and team found that dextroamphetamine improved speech processing in patients with Broca's aphasia and Anomic aphasia, suggesting the drug may enhance brain repair and therapy outcomes.
Researchers found that the left inferior frontal gyrus (LIFG) is necessary to resolve word competition during speech. This brain region, including Broca's area, is responsible for aspects of speech production and language processing.
Patients with primary progressive aphasia are more likely to have a history of learning disabilities, suggesting an underlying susceptibility to language network difficulties. The study highlights the potential for learning disabilities to be underestimated among affected individuals and their families.
This issue of JRRD features several studies exploring advancements in ambulation and motor control for individuals with spinal cord injury. Researchers found that functional electric stimulation systems can significantly improve walking distance and speed, while a new measure for assessing spasticity impact was also developed.
Researchers found that listeners more quickly recognize verbs as genuine when they have a meaning related to the verb in the sentence. The activation of verbs follows the end of the main clause, whereas nouns remain active throughout the sentence.
The study examined clinical and cognitive predictors of swallowing recovery in stroke patients. Identification of specific neurocognitive deficits and clinical features was associated with poor swallowing outcomes.
Research by Lingraphicare America reveals that speech generating devices can help stroke patients recover from aphasia, even years after the initial injury. The study found nearly half of subjects improved to a less severe diagnostic category, with gains observed across all severity levels.
Researchers found significant improvement in language function and mood in patients with non-severe fluent aphasia treated with fluvoxamine maleate, a selective serotonin re-uptake inhibitor. The study used a double-blind crossover design and showed no significant improvement with nilvadipine.
Primary progressive aphasia is a rare form of dementia that affects language abilities while preserving memory. Patients may struggle with word-finding and speaking, but can still recall recent events and maintain complex hobbies.
Research explores vision loss and its impact on driving skills, finding correlations between mental tracking ability and driving measures. Glaucoma patients with normal visual acuity but reduced contrast sensitivity may also struggle with driving skills.
Researchers used low doses of dextroamphetamine in a four-year study of 21 stroke survivors with aphasia. The drug group made significant gains in communication abilities, surpassing 15-point clinically significant changes in 83% of participants.
A study published in Nature found that individuals with aphasia, who experience language loss after a stroke or brain damage, possess an exceptional ability to detect deception. They were able to identify lies cued by facial expressions alone with high accuracy, outperforming other groups.
Researchers at Temple University have found that spatial attention can improve motor and language tasks in individuals with aphasia who have parietal lobe lesions. This means that directing attention to the correct location can enhance performance on various cognitive tasks, including sensory, naming, and reading tasks.
