Active clinical trials for "Agnosia"

The goal of this retrospective is to investigate the relationship between lesion site and neglect anosognosia in subacute or chronic right hemispheric stroke patients with left hemispatial neglect. The main questions it aims to answer are: Was any lesion site related to a higher neglect anosognosia rate? Did any lesion site related to a more severe neglect anosognosia? Participants will be divided into two groups regarding the presence of anosognosia for spatial neglect. Researchers will compare patients with and without anosognosia to see if any lesion site resulted in a higher anosognosia rate and more severe unawareness of neglect symptoms in daily life.

The hypothesis of the study is: Does the Surgical Stress Index (SSI) correlate with the Behavioral Pain Scale (BPS), the Ramsay Sedation Scale (RSS)and/or the Behavioral Pain Scale(BPV) and can therefore be used to monitor the quality of analgosedation in noncommunicative intensive care unit patients?

This is a three year fMRI study conducted at the University of Wisconsin (UW) Hospital and the William. S. Middleton VA Hospital. This study is guided by the hypothesis that reduced fMRI activity and connectivity cortical midline structures (i.e., medial frontal and ventral posterior cingulate cortex) are physiologic abnormalities that relate strongly to the compromised insight into cognitive deficits, or anosognosia, shown by a subset of individuals with amnestic MCI (aMCI) and AD. Further, the investigators hypothesize that these regional changes in fMRI activity are predictive of faster progression from aMCI to AD.

A comparison was made regarding opioid analgesic usage immediately after elective shoulder replacement and for seven days at home between patients randomly given either 0.5% or 0.75% ropivacaine via interscalene block prior to surgery. It is hypothesized that no significant difference will exist between both groups with respect to pain medication used in the hospital and for a 7-day period at home.

Postoperative pain is an important issue after thoracotomy operations. Thoracic epidural analgesia is most popular analgesic method, but sometimes it is not sufficient for pain. This study is designed to compare intercostal block with thoracic epidural analgesia in patients undergoing thoracotomy

This study evaluates two anaesthetic techniques namely interscalene brachial plexus block and intra-articular local anaesthetic injection. Both techniques are currently used for providing postoperative pain relief following arthroscopic shoulder stabilisation operation. It will be a randomised controlled trial involving 30 patients in two groups.

It can be suggested that sympathetic tonus increase and pain, caused by the removal of the effect of epidural analgesia applied at birth, may also affect perfüsion index. The purpose of this study is; To correlate the VAS value at the time of return of epidural analgesia with the PI values at that time and, to test the possibility of using PI variants as an objective tool for predicting pain initiation time and assessing pain.

This study aims to the comparison of Quadratus Lumborum Block 2 and Transversus Abdominis Plan Block for Postoperative Analgesia in Abdominal Surgery

This is a small observational study investigating the physical changes that occur to epidural catheters after insertion for obstetric anaesthesia. Using the observed physical changes as a correlate for the position of the catheter in the patient we will investigate a connection between the position and e function during labour. This information may be useful in guiding the physicians responses to epidurals that do not provide adequate analgesia to aid in deciding on the most appropriate action

The main objective of the study is to explore and map brain areas involved in sensory perception and multisensory integration in patients with central or peripheral neurological damage. The investigators hypothesize for example, that a change (compare to healthy subjects) in the perceptual maps and body representation could be detected and characterize in patients suffering from impairments of peripheral nerve conduction.
