Introduction: Ischemic stroke in young adults has emerged as a relevant health problem today due to its increased incidence, high mortality, the duration of the disability and social consequences. Objective: To describe an approach in diagnosis of ischemic stroke in young adults based on etiopathogenic classification, history and complementary investigations. Method: A wide-ranging bibliographic review was carried out using Google Scholar, searching in bibliographic databases like PubMed, SciELO and Medline, and searching different keywords; 32 articles were chosen in the process with title and abstract were linked with the subject of this review. Development: The etiopathogenic subtypes of ischemic stroke in young adults differ with regard to older adults, and its etiologic causes are more diverse and heterogeneous. Risk factors, personal and family pathological history, non-neurological and neurological clinical manifestations, allow an approach to diagnosis, while complementary investigations facilitate the confirmation of diagnosis, the location and size of the ischemic infarction, definition of the etiological cause and the support of therapeutic decisions. Final considerations: The history and clinical manifestations obtained through interrogation and physical examination, in association with complementary investigations, made it possible an approach to diagnosis of etiopathogenic subtype and the cause of ischemic brain infarction in young adults improving treatment possibilities.(AU)

A rare case of carotid stroke in young due to Takayasu Arteritis with positive anti- cardiolipin antibodies � A case report

Takayasu arteritis is a well-known yet rare form of large vessel vasculitis. Takayasu arteritis affects mainly women, and is most commonly seen in Japan, South East Asia, India, and Mexico, where it usually presents in the 2nd or 3rd decade of life. It is seen usually as pulseless disorder often with bruit at the stenosed arteries. Manifestations range from asymptomatic disease, to catastrophic strokes. Angiography remains the gold standard for diagnosis. Approximately half of those patients treated with steroids will respond, and half of the remaining patients respond to methotrexate; mycophenolatemofetil may be useful. Fertility is not adversely affected and pregnancy does not appear to exacerbate the disease, although management of hypertension is essential. We herewith report a rare case of an11 year old girl, who presented with left-sided hemiparesis, dysarthria, left UMN facial palsy, feeble pulses on right side, high Blood Pressure recordings and positive anti- cardiolipin antibodies. Imaging studies revealed Occluded right Common carotid artery, occluded right subclavian artery and stenotic right renal artery and MRI showed Acute Infarcts in Right Basal Ganglia and Right High Parietal Region, Hemorrhagic infarct in right MCA subcortical area.The diagnosis of Takayasu arteritis with recent cerebrovascular accident (left hemiparesis) with hypertension was made and the patient was started on steroids, anti-platelets, anti-hypertensives and physiotherapy.

Association between white blood cell count,absolute and relative neutrophil count and prognosis in young patients with ischemic stroke / 中风与神经疾病杂志

@#Objective　This study aims to explore the correlation between white blood cell count (WBC),absolute neutrophil count (ANC),relative neutrophil count (RNC) and neurological impairment,poor prognosis at discharge and 90 days after onset.Methods　This study was a retrospective study,including patients aged 18 to 45 years old with first ischemic stroke within 72 hours.NIHSS score at discharge,mRS score at discharge and 90 days were used as outcome.Multivariate logistic regression was used to analyze the relationship between WBC quartile,ANC,RNC and neurological deficit (NIHSS score>4) and poor prognosis (mRS score 2~5).Results　WBC>7.82×10 9/L was independently associated with moderate and severe neurological deficit at discharge and poor prognosis at 90 days.The ANC was only associated with poor prognosis at 90 days,independently.The RNC was an independent risk factor for moderate and severe neurological impairment at discharge,poor prognosis at discharge and 90 days.Conclusion　WBC>7.82×10-9/L is an independent risk factor for moderate and severe neurological impairment at discharge and poor prognosis at 90 days in young patients with stroke.The increase of RNC,which is independently related to moderate and severe neurological impairment and poor prognosis,is more indicative than ANC for poor prognosis in young patients with stroke.

The diagnostic value of high-resolution magnetic resonance in young stroke patients / 中风与神经疾病杂志

@#This study is aimed to explore the value of high-resolution magnetic resonance （HRMRI） in the diagnosis of the etiology of stroke in young adults. Methods We retrospectively enrolled ischemic stroke or transient ischemic attack patients who ≤55 years old admitted in Peking Union Medical College Hospital from January 1，2016 to December 31，2020.Patients were separated into two groups：with or without HRMRI. After collecting the baseline data，clinical features，and imaging characteristics，we explore the differences in the clinical characteristics，the etiology of stroke，and the proportion of cryptogenic stroke between the two groups. The changes of cryptogenic stroke proportion in the HRMRI group before and after HRMRI were further calculated，and the changes of the revised diagnosis were also obtained. Results A total of 155 cases were included in the study. Of those，73 cases （47.1%） underwent HRMRI，while 82 cases （52.9%） did not. HRMRI group was slightly younger than the non-HRMRI group （40.36 VS 43.89，P=0.026），while there were no significant differences in gender，risk factors，and family history. The cryptogenic stroke proportion in the HRMRI group was lower than that in the group without HRMRI （16.4% VS 26.8%，P=0.119）.29% of patients were corrected or make more accurate the diagnosed with the help of HRMRI，reducing cryptogenic stroke by 7%. The changes in the etiology diagnosis mainly from cryptogenic stroke to atherosclerosis disease （5，5/20），and also from other vascular diseases such as arterial dissection to atherosclerosis disease （5，5/20）.Conclusion With HRMRI，nearly one-third of young stroke has revised or accurate for their diagnosis，and the remaining has confirmed for their diagnosis. This technique should be widely used in young stroke patients.

Tuberculous meningitis masquerading as acute ischemic stroke in young adult

Tubercular meningitis (TBM) constitute 5% of all cases of extra pulmonary tuberculosis but a presentation leading to an ischemic stroke in a young adult is a rare clinical entity. In a case of TB vasculopathy, vasculitis, venous thrombosis and aneurysm may be the underlying events leading to a stroke. Stroke in TBM is seen in the tubercular zone which encompasses internal capsule, thalamus and caudate nucleus. Inflammatory mediators like TNF alpha, Interferon gamma and vascular endothelial growth factor have been implicated in the pathogenesis of arteritis. Imaging modalities like MRI show lesions which are usually bilateral in the territory of the perforating vessels. We report a case of 24 year old Asian male who presented with complaints of headache, projectile vomiting and altered sensorium. On examination his Glasgow Coma Scale (GCS) was 10/15, with left oculomotor and left facial nerve palsy, and hypotonia of all 4 limbs with bilateral plantar reflexes being mute. Contrast MRI of brain showed acute infarct, meningeal enhancement and basal exudates. He was started on Anti-tubercular therapy and steroids, but had a poor clinical outcome, due to his late presentation.

Takayasu arteritis presenting with massive cerebral ischemic infarction in a 15-year-old girl: a case report

Takayasu arteritis is a relatively rare type of large-vessel arteritis that primarily affects the aorta and its major branches, the coronary arteries, and the pulmonary arteries. Depending on the different groups of blood vessels involved in the disease process, the clinical presentation of Takayasu arteritis varies. Here we report a case of a girl presenting with a debilitating massive cerebral ischemic infarct that turned out to be a relatively rare first presentation of Takayasu arteritis. Case report of 15 years old adolescent female hailing from lower socio-economic status with past history of chronic headache, no significant family history, completely immunized presented with sudden onset weakness of right upper and lower limbs, which progressed over 1day with aphasia (recovering) with deviation of angle of mouth to left side On examination left radial ,carotid artery not palpable. Her laboratory results showed an elevated C-reactive protein and erythrocyte sedimentation rate, and subsequent CT angiography demonstrated narrowing and occlusion of the major branches of her aortic arch. We report the case of a patient with Takayasu arteritis presenting with a massive cerebral ischemic infarct and review the current literature on this topic. Conclusion of takayasu arteritis is a relatively rare disease with various and sometimes devastating clinical manifestations, such as massive cerebral ischemic infarction as in our case. Currently, there are multiple diagnostic tools and treatment options available, and more under investigation. Early, appropriate diagnosis and initiation of proper therapy could avoid further progression and reduce complications of the disease.

Misdiagnosis of acute ischemic stroke in young patients

Misdiagnosis is a challenging risk in young patients with ischemic stroke that leads to delayed recognition, prevents thrombolytic therapy and increases morbidity and mortality. To assess the frequency and reasons for misdiagnosis of ischemic stroke in young adults in the emergency department, we retrospectively evaluated 101 consecutive patients. The diagnosis required both the presence of an ischemic lesion in diffusion-weighted MRI as well as neurological symptoms. Twenty-three individuals were misdiagnosed (15 females, mean age 43 years [range 26-55 years]). The most common diagnostic errors included headache/ neck pain n = 11 (48%) and peripheral vertigo n = 4 (17.3%), and the most common missed etiology was arterial dissection (AD) n = 15 (65.2%). The initial diagnosis was made by emergency physicians in 22 persons. The group with misdiagnosis had a significantly higher frequency of AD at 15 vs. 8 (p < 0.01), posterior territory involvement at 12 vs. 6 (p < 0.01), and female predominance. Misdiagnosis occurred in a third of young patients with an ischemic stroke and was more frequent in those with arterial dissection involving the posterior circulation and presenting with non-specific symptoms.

El error diagnóstico es una situación riesgosa en pacientes jóvenes con infarto cerebral, ya que conduce a demora en el reconocimiento, previene la administración de terapia trombolítica e incrementa la morbimortalidad. Para valorar la frecuencia y las razones de errores en esta población, evaluamos retrospectivamente 101 pacientes consecutivos. El diagnóstico de infarto cerebral requirió tanto la presencia de lesión isquémica aguda en resonancia magnética como también la presencia de síntomas neurológicos. Veintitrés pacientes fueron mal diagnosticados (15 mujeres, edad media 43 años, [rango 26-55 años]). El error más frecuente incluyó cefalea/cervicalgia n = 11 (48%) y vértigo periférico n = 4 (17.3%). La etiología menos sospechada fue disección arterial n = 15 (62.2%). La evaluación inicial en 22 pacientes fue realizada por emergentólogos. El grupo con errores tuvo significativamente mayor frecuencia de disección arterial 15 vs. 8 (p < 0.01), afectación del territorio posterior 12 vs. 6 (p < 0.01) y sexo femenino. En conclusión, los errores diagnósticos ocurrieron en un tercio de los pacientes jóvenes con infarto cerebral, y fueron más frecuentes en aquellos con disección arterial, compromiso del territorio posterior y síntomas de presentación inespecífica.

Co-occurrence of syndrome of horizontal gaze palsy with progressive scoliosis with stroke in young: a case report.

Horizontal Gaze Palsy with Progressive Scoliosis (HGPPS) is a rare autosomal recessive syndrome of hind brain maldevelopment associated with ocular and skeletal manifestations. To the best of our knowledge there have been no case reports from India although a family of Indian decent has been reported from Saudi Arabia. The clinical and MRI features along with its co-occurrence with stroke in young will be described in this paper.
