Active clinical trials for "Neurologic Manifestations"

A growing number of studies highlight the persistence of symptoms after the acute phase of SARS-CoV-2 infection, including in outpatients with mild to moderate forms of the disease. More than 80% of patients with persistent post-COVID-19 symptoms reported neurologic and neurocognitive disturbances. The pathophysiological mechanism is currently unknown, and several hypotheses have been put forward. Involvement of a Somatic Symptom Disorder (SSD) is plausible given the similarity of these symptoms with the Chronic Fatigue Syndrome identified as a SSD subtype. The objective of the SOMATiC study (SOMAtic symptom disorders Triggered by COVID-19) is to determine whether a positive diagnosis of SSD can be asserted in patients with persistent post-COVID-19 neurological symptoms.

This study is a prospective observational cohort study to document the prevalence and types of neurological manifestations among hospitalized patients with confirmed or suspected novel coronavirus infection (COVID-19).

To study, prospectively, the association between dietary patterns and risk of health outcomes (cardiovascular, metabolic, endocrine, neurological, skeletal muscular, cancer) in cohort study of 116,671 women age 24 to 44 years at baseline in 1989 (the Nurses' Health Study II; NHS II).

The purpose of this study is to improve spasticity diagnosis through development of a simple physical examination guide for primary care providers to identify patients who would benefit from being referred to a movement disorders neurologist for a spasticity evaluation.

The purpose of this study is to improve spasticity diagnosis through exploration of potential new diagnostic markers for spasticity that can assist in diagnosis and referral.

The purpose of this study is to perform a secondary analysis of pre-existing de-identified limited datasets obtained from sites participating in Tier 1 (STUDY20040154: Neurologic Manifestations of COVID 19 in Children) and Tier 2 (STUDY20040278: Neuro COVID - Outcomes). The data will be used to determine the prevalence and severity of neurological symptoms among patients requiring critical care admission for confirmed or suspected novel coronavirus (COVID-19) and to determine the predictors for limitation of care in the study population, as well as, the prognosis of neurologically injured patients admitted to the ICU during the COVID-19 crisis. This study is sponsored by the Pediatric Neurocritical Care Research Group (PNCRG) and sponsored and funded in part by the Neurocritical Care Society.

The objective of this project is to determine the concordance between the subjective and objective evaluation of cognitive functions in affective patients in partial remission through scales and cognitive tests that would be easily implemented in the different mental health care devices. This is a cross-sectional case-control study of non-probabilistic sampling, which will include a group of patients diagnosed with Major Depressive Disorder and Bipolar Disorder and a group of healthy controls from the same population and matched by age, gender and years of education with the group of patients. Patients will be recruited from the psychiatric service of the Hospital de la Santa Creu i Sant Pau who meet the inclusion criteria, and they will undergo a blood draw, a clinical assessment, a complete neuropsychological examination together with scales of subjective perception of cognitive deficit, a measure of cognitive reserve and an evaluation of psychosocial functionality. In addition, the same evaluation will be made to a group of healthy subjects.The total sample will be 120

Stroke is the 4th leading cause of mortality in Hong Kong. It also carries considerable socioeconomical consequences due to disability. Ischemic stroke can be classified by the TOAST classification, which includes large artery atherosclerosis, cardioembolism, small-artery occlusion and other causes (1). Among which, intracranial atherosclerosis (ICAS) had been major cause of acute ischemic stroke (AIS) in the Asia Pacific. It was estimated as high as 24.1% of AIS or transient ischemic attacks (TIAs) were attributed to ICAS in China (2). Management of ICAS related strokes has been challenging owing to its high rate of recurrence despite medical therapy. Recent randomized clinical trial suggested that aggressive medical therapy may result in reduction in recurrence compared with historical cohorts (3). Our group has previously observed a 2.5-fold increase in atrial fibrillation related stroke over a 15-year period (4). The inverstigator also observed a decline in ICAS related AIS as well as its recurrent stroke risk throughout the recent years. Possible mechanisms include better management of metabolic risk factors and aggressive secondary prevention. Other possible reasons are increased atrial fibrillation (AF), small vessel disease (SVD) or other stroke mechanisms. This study is aim to find the evolution of different stroke subtypes in relation to the characteristics of our stroke population over a 15-year period. This may influence territorial prevention strategy.

The purpose of this study is to find out whether patients receiving spinal anesthesia containing lidocaine and sufentanil get transient neurological symptoms.

In high-volume trauma centers, multi-slice CT scanners have become the routine imaging modality for screening trauma patients due to their speed and accuracy. In trauma patients with no known neurologic deficits, diagnostic CT is often obtained though it remains unclear whether this affects management of the patient [1]. With the growing cost of health care, a careful look at the benefit and cost of CT is needed to determine how to best utilize this modality in the evaluation of trauma patients. HYPOTHESIS: In trauma patients with absence of neurologic defects, the addition of comprehensive CT does not change overall clinical management.
