Background: Limb-shaking is one of the transient ischemic attacks (TIA) ‘chameleons.’ This literature review aims to evaluate the clinical, epidemiological profile, pathologic mechanisms, and management of limb-shaking TIA. Review Summary: Relevant reports in Medline’s (PubMed) database were identified and assessed by 2 reviewers without language restriction from 1985 to 2022. A total of 82 reports containing 161 cases that developed limb-shaking TIA were reported. The mean and median age were 61.36 (SD: 15.29) and 62 years (range: 4–93 y). Most of the individuals affected were males (64.34%). Limb-shaking was reported as unilateral in 83.33% of the patients. Limb-shaking presented with other neurological deficits in 44.33% of the individuals, in which the most common concurrent neurological deficit was the weakness of at least 1 limb. A recurrence of the “shaking” phenomenon was observed in 83 individuals. A trigger of limb-shaking was reported in 69 cases, and the most common was changing body position. The internal carotid artery was the most frequent vessel involved in limb-shaking. A chronically occluded internal carotid artery was observed in 42 individuals. Hypertension was the most common comorbidity. The management was conservative in 42.30% of the cases. The most frequent misdiagnoses were seizures. A full recovery was achieved in 56.60% of the individuals. Conclusions: Limb-shaking TIA could be defined as involuntary, rhythmic, brief (<5 min), recurrent, jerky movement usually precipitated by activities that may reduce cerebral blood flow. The “shaking” phenomenon was primarily described as a manifestation of symptomatic complete internal carotid artery obstruction.

“…The characteristics of EEG activity related to sex are not described. Works that indicated the age and gender of patients in the EEG response to hyperventilation sex specificity and differences are not mentioned ( 8 , 10 , 29 ). We suppose that the study is informative to compare brain maturation and development in healthy and pathological conditions in women and men.…”

“…Further, it is accepted that electroencephalography (EEG) is an objective and reliable method for describing normal and pathological processes of the CNS (7,8). HPT presented during EEG might advance the diagnostic value of epilepsy (9,10) and increase the accuracy of the results in a clinical study (11)(12)(13)(14)(15) and scientific research for various neurological disorders (16)(17)(18)(19)(20)(21). The practice proves that the EEG responses to hyperventilation are heterogeneous (1,22,23).…”

Introduction: Hyperventilation provocation test(s) (HPT) concomitant to electroencephalography (EEG) may detect hidden disorders of the nervous system (CNS). There are various types of abnormal EEG in responses to HPT that provoke different interpretations. However, it is not evident how the onset time of pathological EEG responses to hyperventilation (PERH) reveals dysfunction of the CNS in humans. It is also not clear if age and biological sex affect EEG characteristics in response to HPT. Our previous studies have revealed three types of PERH (disorganization of basic rhythm, paroxysmal discharges, epileptiform activity) concerning the manifestation time of first, second, and third minutes. The current work aims to classify the PERH with regards to age (3–6, 7–12, 13–18, 19–30, 31–50, 50 > year) and the biological sex of the patients.Methods: This study examined the EEG of 985 outpatients with various functional disorders of the CNS. The patients were assigned to one of three experimental groups based on the time occurrence of PERH in response to the HPT.Results: The disorganized basic EEG rhythm in the first, second, third minute of HPT was observed across all age and sex groups. All three types of PERH in the first minute were comparable for both sexes. However, some discrepancies between females compared to males were observed in the second and third minutes. All three types of PERH in the first and the second minutes were found only in women. The second type of PERH has revealed at the second minute of PHT in 13–18-year-old five girls.Conclusion: The three main types of PERH were detected at the first minute in all age groups and sex in patients with various CNS dysfunctions. It is diagnostically informative should be used as a marker during the monitoring of treatment. The specific activity of the brain's response to HPT depends on time, age, sex. The data indicate that taking into account sex differences and age during HPT leads to better results. The sensitivity and severity of the NS reaction toward hypocapnia, stress, and emotion increase in women. Therefore, in such cases should not be recommended to expand functional loads.

“…This classification is due to the high likelihood of unilateral occlusion progressing to bilateral occlusion in children. It is worth noting that posterior circulation is usually unaffected in MMD, but it can be involved in Moyamoya syndrome [50] [51].…”

Moyamoya disease (MMD) is a condition characterized by the gradual narrowing and blockage of blood vessels in the brain, specifically those in the circle of Willis and the arteries that supply it. This results in reduced blood flow and oxygen to the brain, leading to progressive symptoms and potential complications. The underlying pathophysiological mechanism remains elucidated. However, recent studies have highlighted numerous etiologic factors: abnormal immune complex responses, susceptibility genes, branched-chain amino acids, antibodies, heritable diseases, and acquired diseases, which may be the great potential triggers for the development of moyamoya disease. Its clinical presentation has varying degrees from transient asymptomatic events to significant neurological deficits. Moyamoya disease (MMD) shows different patterns in children and adults. Children with MMD are more susceptible to ischemic events due to decreased blood flow to the brain. Conversely, adults with MMD are more prone to hemorrhagic events involving brain bleeding. Children with MMD may experience a range of symptoms including motor impairments, sensory issues, seizures, headaches, dizziness, cognitive delays, or ongoing neurological problems. Although adults may present with similar clinical symptoms as children, they are more prone to experiencing sudden onset intraventricular, subarachnoid, or intracerebral hemorrhages. One of the challenges in moyamoya disease is the potential for misdiagnosis or delayed diagnosis, particularly when physicians fail to consider MMD as a possible cause in stroke patients. This review aims to provide a comprehensive overview of recent global studies on the pathophysiology of MMD, along with advancements in its management. Additionally, the review will delve into various surgical treatment options for MMD, as well as its rare
