Improved language function for post-stroke aphasia in the long term following repeated repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy: a case report
ConclusionsThe findings of the study indicate that the repeated use of repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy may be effective in improving and preserving language function and increasing cerebral blood flow for aphasia following stroke.

Which is responsible for aphasia by subcortical lesions? Subcortical lesions or the cortical hypoperfusion?
This study showed that aphasia to be more common in cases with cortical hypoperfusion in the dominant hemisphere than in cases without hypoperfusion. Our results provide evidence that direct effect of the lesion in the basal ganglia on the development of aphasia is doubtful.PMID:35984244 | DOI:10.1080/01616412.2022.2112369

Aphasia Induced by Infratentorial Ischemic Stroke: Two Case Reports
Aphasia induced by an infratentorial stroke has rarely been reported, and its mechanism has not been fully identified. We evaluated two individuals who had been admitted to Saiseikai Kumamoto Hospital in Kumamoto, Japan, due to acute ischemic stroke in order to determine whether their aphasia was induced by an infratentorial stroke. The first patient, a 59-year-old man with a history of left parietal embolic stroke with very mild sequelae of anomia, developed Wernicke’s aphasia, nonfluent speech, and right limb ataxia as a result of the stroke. The second patient, a 76-year-old woman with a history of chronic renal failu...

Nonconvulsive Status Epilepticus With Neuropsychological Symptoms: Two Case Reports
We report two such cases. Case 1, a 62-year-old man with a history of a subcortical hemorrhage in the right lateral temporal lobe and a brain infarct in the left medial temporo-occipital lobes, suddenly developed left unilateral spatial neglect and visual object agnosia. Diffusion-weighted imaging indicated status epilepticus, not stroke. His deficits resolved immediately after treatment with diazepam and phenytoin sodium. Case 2, a 61-year-old man with a history of brain infarcts in the right lateral temporal and left medial temporo-occipital lobes, suddenly developed global aphasia and cortical deafness. An MRI revealed ...

Left thalamus infarction in the thalamotuberal artery perfusion area causing subcortical diaschisis and transcortical sensory aphasia
The thalamus is related to language function, and some thalamic stroke cases can cause aphasia [1]. However, most previous cases reporting thalamic damage-induced ipsilateral subcortical diaschisis and aphasia were hemorrhagic stroke [1,2]. Only a few left thalamus infarction cases showed cortical hypoperfusion concerned with the aphasia, but no single-photon emission computed tomography (SPECT) or thalamic nucleus data were available [3]. Thus, aphasia pathology due to cortical hypoperfusion following thalamus infarction, especially with respect to thalamic nuclei, is still unknown.

Anterior Choroidal Artery Infarction Evaluated with 123I-Imp Single-Photon Emission Computed Tomography and 7 Tesla Magnetic Resonance Imaging
Anterior choroidal artery (AchA) infarction remains a challenging diagnosis although it was first described almost 100 years prior. N-isopropyl-p-[123I]-iodoamphetamine single-photon emission computed tomography (123I-IMP SPECT) and 7 Tesla magnetic resonance angiography (7T-MRA) are not routinely performed in cases of AchA infarction. Therefore, the application of 123I-IMP SPECT and 7T-MRA for AchA infarction has not been reported previously. A 67-year-old man presented with disturbed consciousness, gaze preference to the left, aphasia, right homonymous hemianopia, and right hemiparesis.

Progressive Cerebral Ischemia and Intracerebral Hemorrhage after Indirect Revascularization for a Patient with Cerebral Proliferative Angiopathy
We previously reported a patient with cerebral proliferative angiopathy (CPA) who showed cerebral ischemia in resting and acetazolamide-stressed N-isopropyl-p-[123I] iodoamphetamine single-photon emission computed tomography (123I-IMP-SPECT). At onset, the patient was treated conservatively. However, during the 2 years following initial onset, his hemiparesis and aphasia had gradually aggravated and his IQ scores were markedly decreased. MRI revealed progressive vascular proliferation and brain atrophy.

Migrainous Infarction in a Patient With Sporadic Hemiplegic Migraine and Cystic Fibrosis: A 99mTc-HMPAO Brain SPECT Study.
We describe the case of a patient with CF, who had a migrainous stroke during an SHM attack. A 32-year-old Caucasian male was diagnosed with CF, with heterozygotic delta F508/unknown CFTR mutation. The patient experiences bouts of coughing sometimes triggering SHM attacks with visual phosphenes, aphasia, right-sided paresthesia, and hemiparesis. He had a 48-hour hemiparesis triggered by a bout of coughing with hemoptysis, loss of consciousness, and severe hypoxia-hypercapnia. MRI demonstrated transient diffusion hyperintensity in the left frontal-parietal-occipital regions resulting in a permanent infarction in the primary...

Uneven cerebral hemodynamic change as a cause of neurological deterioration in the acute stage after direct revascularization for moyamoya disease: cerebral hyperperfusion and remote ischemia caused by the ‘watershed shift’
AbstractSuperficial temporal artery-middle cerebral artery (STA-MCA) anastomosis is the standard surgical treatment for moyamoya disease (MMD). The main potential complications of this treatment are cerebral hyperperfusion (CHP) syndrome and ischemia, and their managements are contradictory to each other. We retrospectively investigated the incidence of the simultaneous manifestation of CHP and infarction after surgery for MMD. Of the 162 consecutive direct revascularization surgeries performed for MMD, we encountered two adult cases (1.2%) manifesting the simultaneous occurrence of symptomatic CHP and remote infarction in...

Effects of Low-Frequency Repetitive Transcranial Magnetic Stimulation Combined with Intensive Speech Therapy on Cerebral Blood Flow in Post-Stroke Aphasia
Abstract
We provided an intervention to chronic post-stroke aphasic patients using low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) guided by a functional magnetic resonance imaging (fMRI) evaluation of language laterality, combined with intensive speech therapy (ST). We performed a single photon emission-computed tomography (SPECT) scan pre- and post-intervention and investigated the relationship between cerebral blood flow (CBF) and language function. Fifty right-handed chronic post-stroke aphasic patients were enrolled in the study. During their 11-day hospital admission, the patients receiv...

Refractory status epilepticus due to SMART syndrome
Conclusions Taking into account clinical evolution and ictal neuroimaging studies, status epilepticus could explain the origin of these episodes in SMART syndrome. Although most patients have reversible symptoms, in some cases, aggressive treatment to avoid sequelae is needed. This article is part of a Special Issue entitled “Status Epilepticus”.
