Damage to the Left Precentral Gyrus Is Associated With Apraxia of Speech in Acute Stroke Clinical Sciences
Conclusions— Damage to the left precentral gyrus is associated with AOS in acute to subacute stroke patients, suggesting a role of this brain region in motor speech production.

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...

A Case of Recurrent Ischemic Stroke Involving Subacute, Progressive Intracranial Cerebral Arterial Sclerosis Prior to Diagnosis with -mutated Polycythemia Vera
A 58-year-old man presenting with no vascular risk factors visited our hospital with right hemiparesis and total aphasia. Diffusion-weighted magnetic resonance imaging of the brain showed multiple hyperintensities in watershed distributions in the left hemisphere. Magnetic resonance angiography (MRA) revealed stenosis of the middle cerebral artery, despite normal MRA findings 2 months prior. One year after the first stroke, the patient experienced a recurrent ischemic stroke involving the left anterior choroidal artery, pulmonary embolism, and deep venous thrombosis.

A right convergence area of the prefrontal lobe is involved in the improvement of semantic fluency in patients with post-stroke aphasia
CONCLUSION: The improvement of semantic fluency in subacute PSA patients may require the participation of the right convergence area of the prefrontal lobe.PMID:37651207 | DOI:10.1080/10749357.2023.2253632

Patterns of Poststroke Brain Damage That Predict Speech Production Errors in Apraxia of Speech and Aphasia Dissociate Clinical Sciences
Conclusions— AOS likely occurs in conjunction with aphasia because of the proximity of the brain areas supporting speech and language, but the neurobiological substrate for each disorder differs.

Different Perfusion Patterns in a Patient with Acute Ischemic Stroke
A 29-year-old male patient with aphasia and mild weakness of the right arm arrived at the emergency room 4 hours after symptom onset. The computed tomography perfusion showed a typical delay in the time-based maps in the left occipital lobe and another hyperperfused area in the left frontal lobe. The follow-up magnetic resonance imaging confirmed cortical ischemic lesions in both areas. This case shows that besides hypoperfusion, hyperperfusion can also be found in the first stages of acute stroke, and it is highly suggestive of established ischemic lesions.

Ischemic Stroke Secondary to Paradoxical Embolism Through a Pulmonary Arteriovenous Malformation: Case Report and Review of the Literature
We report a 32-year-old man who presented with an abrupt onset of right facial weakness and expressive aphasia. Brain magnetic resonance imaging revealed an acute infarct in the left middle cerebral artery territory and chronic infarcts in the bilateral cerebellar hemispheres. A cardioembolic mechanism was initially considered in the setting of perimyocarditis diagnosed a few months earlier.

Anxiety in Patients With Acute Ischemic Stroke: Risk Factors and Effects on Functional Status
Conclusion: Depressive symptoms are the major correlates of PSA while more severe PSA is associated with poorer ADL and health-related QOL. Acute lesions involving CHWM may correlate with PSA in ischemic stroke patients with mild-to-moderate neurologic deficits, supporting a lesion-location hypothesis in PSA.IntroductionAnxiety is prevalent after stroke and occurs in about one-quarter of stroke survivors (1, 2). Poststroke anxiety (PSA) may have a negative impact on quality of life (QOL) of stroke survivors, affecting their rehabilitation (3). Furthermore, one prospective study found that severe anxiety symptoms were assoc...

Lesion-aphasia discordance in acute stroke among Bengali-speaking patients: Frequency, pattern, and effect on aphasia recovery
ConclusionLesion-aphasia discordance following acute stroke is not uncommon among Bengali-speaking subjects. In the discordant group, preponderance towards non-fluent aphasia was observed. Discordance occurred more frequently after hemorrhagic stroke. Subjects with lesion-discordant aphasia presented better recovery during early post-stroke phase.
