BACKGROUND Recovery from post-stroke aphasia is a long and complex process with an uncertain outcome. Various interventions have been proposed to augment the recovery, including constraint-induced aphasia therapy (CIAT). CIAT has been applied to patients suffering from post-stroke aphasia in several unblinded studies to show mild-to-moderate linguistic gains. The aim of the present study was to evaluate the neuroimaging correlates of CIAT in patients with chronic aphasia related to left middle cerebral artery stroke...

Moyamoya disease is an idiopathic progressive vasculopathy of distal internal carotid artery and circle of Willis which leads to the development of characteristic smoky appearance of the vascular collateral network on angiography. With the highest reported incidence among Japanese population, it has been under recognized as a cause of cerebrovascular accidents in Western countries. Here we report a case of a young 20-year-old Caucasian woman who presented to the emergency department with expressive aphasia, right arm weakness and numbness for three days...

REVIEW
Donna C Tippett, Argye E Hillis
The sequelae of post-stroke aphasia are considerable, necessitating an understanding of the functional neuroanatomy of language, cognitive processes underlying various language tasks, and the mechanisms of recovery after stroke. This knowledge is vital in providing optimal care of individuals with aphasia and counseling to their families and caregivers. The standard of care in the rehabilitation of aphasia dictates that treatment be evidence-based and person-centered. Promising techniques, such as cortical stimulation as an adjunct to behavioral therapy, are just beginning to be explored...

Primary Progressive Aphasia (PPA) is a neurodegenerative condition characterized by insidious irreversible loss of language abilities. Prior studies suggest that transcranial direct current stimulation (tDCS) directed toward language areas of the brain may help to ameliorate symptoms of PPA. In the present sham-controlled study, we examined whether tDCS could be used to enhance language abilities (e.g., picture naming) in individuals with PPA variants primarily characterized by difficulties with speech production (non-fluent and logopenic)...

BACKGROUND: This work focuses on the twenty-six individuals who provided data to AphasiaBank on at least two occasions, with initial testing between 6 months and 5.8 years post-onset of aphasia. The data are archival in nature and were collected from the extensive database of aphasic discourse in AphasiaBank. AIMS: The aim is to furnish data on the nature of long-term changes in both the impairment of aphasia as measured by the Western Aphasia Battery-Revised (WAB-R) and its expression in spoken discourse...

BACKGROUND: Neurosurgical application of indocyanine green (ICG) videography prior to performing a dural opening has been reported as transdural ICG videography and used during surgery of meningiomas associated with venous sinuses, as well as cranial and spinal arteriovenous malformations. However, its use for a superficial temporal artery to middle cerebral artery (STA-MCA) bypass has not been reported. METHODS: We performed a retrospective analysis of medical records of patients who underwent a transdural ICG videography technique during STA-MCA bypass procedures performed between January 2012 and March 2015...

A Japanese woman developed frontotemporal dementia (FTD)-like symptoms of abnormal behavior, such as stereotyped behavior and disinhibition. The patient developed these symptoms at the age of 59 years, although aphasia symptoms were not apparent at early disease stages. Progressive parkinsonism was dominant on the left side, and conspicuous myoclonus was recognized in the late disease stage. MRI indicated severe, right side-dominant frontotemporal lobe atrophy with white matter degeneration. Brainstem and cerebellar atrophy were also observed...

Imageability is a psycholinguistic variable that indicates how well a word gives rise to a mental image or sensory experience. Imageability ratings are used extensively in psycholinguistic, neuropsychological, and aphasiological studies. However, little formal knowledge exists about whether and how these ratings are associated between and within languages. Fifteen imageability databases were cross-correlated using nonparametric statistics. Some of these corresponded to unpublished data collected within a European research network-the Collaboration of Aphasia Trialists (COST IS1208)...

Using text-to-speech technology to provide simultaneous written and auditory content presentation may help compensate for chronic reading challenges if people with aphasia can understand synthetic speech output; however, inherent auditory comprehension challenges experienced by people with aphasia may make understanding synthetic speech difficult. This study's purpose was to compare the preferences and auditory comprehension accuracy of people with aphasia when listening to sentences generated with digitized natural speech, Alex synthetic speech (i...

BACKGROUND: People with aphasia (PWA) use pantomime, gesture in absence of speech, differently from non-brain-damaged people (NBDP). AIMS: To evaluate through an exploratory study the comprehensibility of PWA's pantomimes and to find out whether they can compensate for information PWA are unable to convey in speech. METHODS & PROCEDURES: A total of 273 naïve observers participated in one of two judgement tasks: forced-choice and open-ended questions...

We examined sequential learning in individuals with agrammatic aphasia (n = 12) and healthy age-matched participants (n = 12) using an artificial grammar. Artificial grammar acquisition, 24-hour retention, and the potential benefits of additional training were examined by administering an artificial grammar judgment test (1) immediately following auditory exposure-based training, (2) one day after training, and (3) after a second training session on the second day. An untrained control group (n = 12 healthy age-matched participants) completed the tests on the same time schedule...

Music is part of the human nature, and it is also philogenically relevant to language evolution. Language and music are bound together in the enhancement of important social functions, such as communication, cooperation and social cohesion. In the last few years, there has been growing evidence that music and music therapy may improve communication skills (but not only) in different neurological disorders. One of the plausible reasons concerning the rational use of sound and music in neurorehabilitation is the possibility to stimulate brain areas involved in emotional processing and motor control, such as the fronto-parietal network...

Stroke remains a major cause of disability throughout the world: paralysis, cognitive impairment, aphasia, and so on. Surgical or medical intervention is curative in only a small number of cases. Nearly all stroke cases require rehabilitation. Neurorehabilitation generally improves patient outcome, but it sometimes has no effect or even a mal-influence. The aim of this review is the clarification of the mechanisms of neurorehabilitation. We systematically reviewed recently published articles on neural network remodeling, especially from 2014 to 2016...

It is well established that networks within multiple-demand cortex (MDC) become active when diverse skills and behaviors are being learnt. However, their causal role in learning remains to be established. In the present study, we first performed functional magnetic resonance imaging on healthy female and male human participants to confirm that MDC was most active in the initial stages of learning a novel vocabulary, consisting of pronounceable nonwords (pseudowords), each associated with a picture of a real object...

BACKGROUND/AIMS: Prior studies of late-onset Alzheimer disease (AD) have reported that cerebrospinal fluid (CSF) tau levels correlate with hippocampal/medial temporal lobe atrophy. These findings suggest that CSF tau indices in AD may reflect tau-related neurodegeneration in the medial temporal lobe. However, it remains uncertain whether elevated CSF tau levels in the clinically heterogeneous subtypes of early-onset AD (EOAD; amnestic, posterior cortical atrophy [PCA], and logopenic progressive aphasia [LPA]) are attributable to similar underlying mechanisms...

Posterior reversible encephalopathy syndrome has been associated with hypertension, preeclampsia, cancer chemotherapy, and drugs of abuse, such as amphetamine and methamphetamine. We report a young man who suddenly developed severe headache, disorientation, and aphasia following ingestion of kratom and Adderall. Computed tomography and magnetic resonance imaging of his head revealed foci of vasogenic edema in the posterior occipital lobes, frontal lobes, and brainstem. In addition, he had a small area of hemorrhage in the left posterior occipital lobe...
