Quantitative Limbic System Mapping of Main Cognitive Domains in Multiple Sclerosis
Background and objective Cognitive impairment (CI) is common in multiple sclerosis (MS), but underlying mechanisms and their imaging correlates are not completely understood. The gray and white matter structures of the limbic system (LS) play crucial roles in different aspects of cognition. To investigate their role in MS related CI, and since a detailed evaluations are lacking in the literatur...

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...
Quantitative magnetization transfer mapping of bound protons in multiple sclerosis.
Quantitative analysis of magnetization transfer images has the potential to allow a more thorough characterization of the protons, both bound and free, in a tissue by extracting a number of parameters relating to the NMR properties of the protons and their local environment. This work develops previously presented techniques to produce estimates of parameters such as the bound proton fraction, ...
متن کاملMultiple Sclerosis Cognitive Impairment in Multiple Sclerosis
Multiple sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system. Although MS has been known since the 19th century, cognitive impairment (CI) was only recognised as an important feature of MS over the past 30 years. The reason is that, until recently, MS was perceived exclusively as a white matter disease, and cognition was thought to depend solely on the ...
متن کاملCorrelation of MRI findings and cognitive function in multiple sclerosis patients using montreal cognitive assessment test
Background: Magnetic resonance imaging (MRI) has improved the diagnosis and management of patients with multiple sclerosis (MS). Montreal Cognitive Assessment (MoCA) is a brief, sensitive test that has been recommended by National Institute of Neurological Diseases and Stroke and Canadian Stroke Network (NINDS-CSN) as a reliable tool to detect mild cognitive impairments. This study aimed to eva...
