BACKGROUND
Although rare, paradoxical embolism sometimes occurs with patent ductus arteriosus (PDA). This study presents a case of PDA-associated paradoxical embolism with acute ischemic stroke (AIS) and pulmonary embolism (PE) following thoracoscopic surgery.
CASE PRESENTATION
A 65-year-old woman developed acute-onset aphasia and right hemiparesis on the third day following thoracoscopic resection for a right lung tumor. Brain magnetic resonance imaging revealed multiple infarcts, and lower extremity venous Doppler ultrasound revealed deep vein thrombosis. The patient subsequently developed dyspnea, tachycardia, and hypoxemia. PE was confirmed by percutaneous transfemoral venous selective pulmonary angiography, which meanwhile demonstrated a PDA lesion. The patient, after receiving catheter-directed thrombolysis and inferior vena cava filter placement, improved in both neurological and respiratory status.
CONCLUSION
For an uncommon but potentially fatal case with PDA-induced paradoxical embolism causing AIS and PE, early recognition and treatment are vital. Further studies are warranted to determine the optimal management and prognosis of patients with PDA-related embolic events.

BACKGROUND
Sturge-Weber syndrome (SWS) is a complex rare genetic neuro-cutaneous disorder characterized by the presence of a port-wine stain, ophthalmic and intracranial angiomatosis leading to seizures, ocular, and oral abnormalities.
CASE PRESENTATION
We report a 39-year-old, non-diabetic, non-hypertensive female refugee who presented initially with heart failure due to anemia for which she received blood transfusions. Later on admission, she developed multiple focal to bilateral seizures, severe irritability, aphasia, and right-sided hemiplegia, leading to admission to the ICU. A repeat medical history and examination revealed a faint left-sided ophthalmic port-wine stain that was initially unnoticed and a remote history of unprovoked seizures 20 years ago. Imaging revealed parietal calcifications and confirmed the diagnosis of SWS. Thus, a multidisciplinary approach was taken to fully understand the patient's diagnosis and determine a treatment strategy, involving consultations with the neurology, ophthalmology, otolaryngology, and physiotherapy departments. Successful seizure control was achieved by administering IV phenytoin for 3 days and the up-titrating of oral carbamazepine to 1g daily through a nasogastric tube. Unfortunately, due to the unavailability of personnel or resources, other important assessments for patients with SWS, such as advanced neuroimaging, psychiatric, plastic and neuro-surgery evaluations, as well as dentistry reviews, could not be conducted.
CONCLUSION
This case highlights the rare occurrence of adult-onset seizures in an undiagnosed SWS and their re-emergence after almost two decades without anti-seizure medications. It also highlights the importance of a comprehensive history and clinical examination, as this patient's diagnosis of SWS could have been missed if she had not experienced seizures on admission. Our study also demonstrates the challenges associated with managing such a complex condition in settings with limited resources.

BACKGROUND
Enhancing speech-language therapy remains the most effective strategy for improving post-stroke aphasia, However, conventional face-to-face interventions often lack the necessary therapeutic intensity. In recent years, mobile application-based speech-language therapy has emerged progressively, offering new opportunities for independent rehabilitation among aphasic patients. This review aims to evaluate the impact of mobile application-based interventions on post-stroke aphasic.
METHODS
By conducting a systematic search across five databases (PubMed, Web of Science, EMBASE, CINAHL, and Scopus), we identified and included studies that investigated the utilization of mobile application-based technologies (such as computers, iPads, etc.) for treating post-stroke aphasia.
RESULTS
This study included 15 research investigations, including 10 randomized controlled trials (RCTs), four self-controlled studies and one cross-over experimental design study. Among these, eight studies demonstrated the efficacy of mobile application-based therapy in enhancing overall language functionality for post-stroke aphasia patients, three studies highlighted its potential for improving communication skills, three studies observed its positive impact on spontaneous speech expression. Moreover, four studies indicated its effectiveness in enhancing naming abilities, two studies underscored the positive influence of mobile application-based interventions on the quality of life for individuals with aphasia. Six studies noted that speech improvement effects were maintained during the follow-up period.
CONCLUSION
The results of this review demonstrate the potential of mobile application-based interventions for improving speech-language function in individuals with aphasia. However, further high-quality research is needed to establish their effects across different domains and to delve into the comparative advantages of various treatment approaches.

Corticobasal syndrome (CBS) is a rare cause of dementia and comprises varied combinations of subcortical signs (akinetic-rigid parkinsonism, dystonia, or myoclonus) with cortical signs (apraxia, alien hand or cortical sensory deficit), usually asymmetric. We aimed to report and compare the clinical and neuroimaging presentation of two patients diagnosed with CBS. While case 1 had severe non-fluent aphasia associated with mild apraxia and limb rigidity, case 2 had a more posterior cognitive impairment, with a different language pattern associated with marked visuospatial errors and hemineglect. FDG PET played a significant role in diagnosis, suggesting, in the first case, corticobasal degeneration and, in the second, Alzheimer's disease pattern. CBS has been widely studied with the advent of new methods such as brain FDG PET. Studies that deepen the phenotypic and biomarker heterogeneity of CBS will be of great importance for better classification, prognosis, and treatment of the condition.

The French composer, Maurice Ravel, at the peak of his career, showed signs of a progressive disorder that affected his ability to function with verbal and musical language, as noted by the neurologist Théophile Alajouanine. The worsening of the disease led to a craniotomy, performed in 1937, which failed to reveal the cause of his illness, and he died shortly thereafter. A lack of post-mortem neuropathological evidence precluded a definitive diagnosis of the illness, which remained enigmatic. Speculations about the precise diagnosis of Ravel's neurological disease have been largely based on Alajouanine's observations, which included aphasia and amusia, mostly expressive, and ideomotor apraxia, while musical judgement, taste, and memory remained relatively intact, implying different neuroanatomical substrates. A possible subform of frontotemporal lobar degeneration complex was the diagnostic suggestion of many authors. His untimely death deprived the world of this remarkable musician, and the music that remained trapped in his mind.

Comparative Study
: As brain lesions present complex diagnostic challenges, accurate tissue sampling via biopsy is critical for effective treatment planning. Traditional frame-based stereotactic biopsy has been complemented by navigated biopsy techniques, leveraging advancements in imaging and navigation technology. This study aims to compare the navigated and frame-based stereotactic biopsy methods in a clinical setting, evaluating their efficacy, safety, and diagnostic outcomes to determine the optimal approach for precise brain lesion targeting. : retrospective analysis was conducted on patients who underwent brain biopsies between January 2017 and August 2023 at an academic medical center. Data on patient demographics, clinical characteristics, biopsy technique (navigated vs. frame-based), and outcomes including accuracy, complications, and hospital stay duration were analyzed. : The cohort comprised 112 patients, with no significant age or gender differences between groups. Symptoms leading to biopsy were predominantly diminished muscle strength (42.0%), cognitive issues (28.6%), and aphasia (24.1%). Tumors were most common in the deep hemisphere (24.1%). The median hospital stay was 5 days, with a rehospitalization rate of 27.7%. Complications occurred in 4.47% of patients, showing no significant difference between biopsy methods. However, navigated biopsies resulted in fewer samples ( < 0.001) but with comparable diagnostic accuracy as frame-based biopsies. : Navigated and frame-based stereotactic biopsies are both effective and safe, with comparable accuracy and complication rates. The choice of technique should consider lesion specifics, surgeon preference, and technological availability. The findings highlight the importance of advanced neurosurgical techniques in enhancing patient care and outcomes.

Review
The WHO Dementia Global Action Plan states that rehabilitation services for dementia are required to promote health, reduce disability, and maintain quality of life for those living with dementia. Current services, however, are scarce, particularly for people with young-onset dementia (YOD). This article, written by an international group of multidisciplinary dementia specialists, offers a three-part overview to promote the development of rehabilitation services for YOD. Firstly, we provide a synthesis of knowledge on current evidence-based rehabilitative therapies for early-onset Alzheimer's disease (EOAD), behavioural variant frontotemporal dementia (bvFTD), primary progressive aphasia (PPA), and posterior cortical atrophy (PCA). Secondly, we discuss the characteristics of rehabilitation services for YOD, providing examples across three continents for how these services can be embedded in existing settings and the different roles of the rehabilitation multidisciplinary team. Lastly, we conclude by highlighting the potential of telehealth in making rehabilitation services more accessible for people with YOD. Overall, with this paper, we aim to encourage clinical leads to begin introducing at least some rehabilitation into their services, leveraging existing resources and finding support in the collective expertise of the broader multidisciplinary dementia professional community.

Review
Post-stroke cognitive impairment is a common and disabling condition with few effective therapeutic options. After stroke, neural reorganization and other neuroplastic processes occur in response to ischemic injury, which can result in clinical improvement through spontaneous recovery. Neuromodulation through transcranial direct current stimulation (tDCS) is a promising intervention to augment underlying neuroplasticity in order to improve cognitive function. This form of neuromodulation leverages mechanisms of neuroplasticity post-stroke to optimize neural reorganization and improve function. In this review, we summarize the current state of cognitive neurorehabilitation post-stroke, the practical features of tDCS, its uses in stroke-related cognitive impairment across cognitive domains, and special considerations for the use of tDCS in the post-stroke patient population.

Review
The cerebellum is emerging as a promising target for noninvasive brain stimulation (NIBS). A systematic review was conducted to evaluate the effects of cerebellar NIBS on both motor and other symptoms in stroke rehabilitation, its impact on functional ability, and potential side effects (PROSPERO number: CRD42022365697). A systematic electronic database search was performed by using PubMed Central (PMC), EMBASE, and Web of Science, with a cutoff date of November 2023. Data extracted included study details, NIBS methodology, outcome measures, and results. The risk of bias in eligible studies was also assessed. Twenty-two clinical studies involving 1016 participants were finally included, with a focus on outcomes related to post-stroke motor recovery (gait and balance, muscle spasticity, and upper limb dexterity) and other functions (dysphagia and aphasia). Positive effects were observed, especially on motor functions like gait and balance. Some efficiency was also observed in dysphagia rehabilitation. However, findings on language recovery were preliminary and inconsistent. A slight improvement in functional ability was noted, with no serious adverse effects reported. Further studies are needed to explore the effects of cerebellar NIBS on post-stroke non-motor deficits and to understand how cerebellar engagement can facilitate more precise treatment strategies for stroke rehabilitation.

Stroke is the most common cause of death and disability in the world, and ischemic etiology plays a major role. Atrial septal aneurysm (ASA) is a localized saccular deformity of the atrial septum, associated with ischemic stroke independently or in association with other atrial septal defects (ASD). There is a higher incidence of stroke in the population with ASD. In these patients, the presence of ASA is an important predictor of recurrent stroke. This is a case of ischemic stroke in a 44-year-old who presented with sudden-onset right-sided body weakness, expressive aphasia, and non-specific confusion for one hour, with an initial National Institutes of Health Stroke Scale (NIHSS) score of 7. CT angiogram revealed occlusion of the M3 branch of the left middle cerebral artery in the left lateral frontal lobe. Code stroke was called, and the patient was given tenecteplase (TNK), after which her right-side weakness and aphasia resolved. Trans-thoracic echo with bubble study showed ASA with positive bubble study. Lone ASA or ASA with concomitant ASD poses a higher risk of recurrent stroke in younger patients, especially those without significant risk factors for strokes. Patients with ASA and concomitant ASD are at high risk for recurrent ischemic stroke and should be kept under surveillance with continued medical therapy. We present a case of ischemic stroke caused by ASA and a review of the current literature and case reports documenting cases with similar presentations.
