Prevalence of Auditory Dysfunction and ICU-acquired Delirium Following Cardiac Surgery With Cardiopulmonary...

Hearing LossCardiac Surgery3 more

AUDICS-ICU is a prospective observational aiming to evaluate the prevalence of auditive dysfunction following cardiac surgery. Participants will undergo audiometric testings before and 3 months after cardiac surgery with cardiopulmonary bypass. Furthermore, the study evaluates hearing loss-associated ICU-acquired delirium after cardiac surgery with cardiopulmonary bypass.

Neurocognitive Changes in Patients With Remitting Relapsing Multiple Sclerosis Treated With Natalizumab...

Multiple SclerosisCognitive Impairment

Cognitive impairment is seen in about half of patients with relapsing remitting MS. Our knowledge about long term development of cognitive performance under natalizumab therapy is limited. We want to demonstrate with this study that patients treated with ntz improve in neurocognitive tests over the long term.

The Montreal Cognitive Assessment as a Screening Tool for Preoperative Mild Cognitive Impairment...

Mild Cognitive Impairment

This is a prospective, double-blinded, control trial. The Montreal Cognitive Assessment is used to screen preoperative mild cognitive impairment in 582 consecutive geriatric patients, scheduled for general, vascular or urological surgery under general and/or regional anesthesia.

The Comparison of Cognition, Depression and Anxiety, and Quality of Life After Hip Fracture Surgery...

Postoperative Cognitive DysfunctionHip Fractures3 more

Postoperative cognitive dysfunction is a relatively common in elderly patients after hip surgery, but exact mechanism of its onset is still unclear as well as contributing factors. There is also increased incidence of depression and anxiety. Both affect the recovery after surgery, slow it down and reduce the quality of life. Patients will be divided into two groups, operated under regional anaesthesia and operated under general anaesthesia, and monitored after surgery. Patients will be tested before and after surgery to evaluate postoperative cognitive deficits, depression and anxiety scale and health-related quality of life questionnaire.

Periodic Limb Movement Syndrome in Patients With Cerebral Small Vessel Disease.

Periodic Limb Movement DisorderCerebral Small Vessel Diseases1 more

Patients from 60 to 75 years old diagnosed with cerebral small vessel disease with no history of symptomatic stroke, brain tumor, traumatic brain injury, seizures and neurodegenerative or mental disorder will undergo overnight leg actigraphy and cardiorespiratory monitoring. Those of them with apnea/hypopnea index under 5 will be enrolled. Brain MRI and cognitive assessment will be performed at baseline and in 1-year follow-up, sleep quality will be assessed at baseline with self-reported questionnaires. Progression of cerebral small vessel disease markers and cognitive dysfunction will be compared between patients with high periodic limb movement index (the number of periodic limb movement ≥ 15 per hour of sleep) and controls (periodic limb movement index < 15/h).

Greek Validation of ACE III Test in Perioperative Patients

Postoperative DeliriumPostoperative Cognitive Dysfunction

Postoperative neurocognitive disorders, including postoperative delirium (POD) and postoperaive cognitive dysfunction (POCD), are common complications of perioperative neurocognition in elderly patients undergoing surgery. POD and POCD have short- and long-term consequences, such as increased hospital stays and costs, augmented morbidity and mortality, as well as higher risk for cognitive decline later in life. Therefore, early prevention and diagnosis of these conditions is of great importance. A number of psychometric tests have been proposed as cognitive screening tools. Given the fact that many of them show weaknesses and difficulties in performance, scientists have sought for more useful alternatives. Montreal Cognitive Assessment (MoCA) is considered to be a good choice, as it has been successfully applied in the perioperative setting. What's more, it has been translated and validated for a Greek population with neurological disorders. Addenbrooke's Congnitive Examination III (ACE III) has been introduced recently into clinical practice. It is an easy to perform and detailed test that covers several neurocognitive domains and has shown high sensitivity and specificity in clinical conditions, including dementia and Alzheimer's disease. Although current literature lacks data concerning its perioperative use, ACE III could prove useful for screening patients undergoing surgery and anesthesia on the basis of its favorable characteristics as mentioned above. The aim of this study is to translate the ACE III (English version 2012) into Greek and assess its validity in perioperative patients aged >55 years.

Validation of a Smartphone Application for the Assessment of Patients With Mild Cognitive Impairment:...

Cognitive ImpairmentAlzheimer Disease

The clinical evaluation of a patient with a cognitive complaint requires neuropsychological tests, evaluating the integrity of memory and other cognitive functions. The initial evaluation is made most often by a doctor (general practitioner). In case of need for further examination, a neuropsychological report is made in consultation memory by a neuropsychologist, with further cognitive tests. The Cognitive Neurology Center at Lariboisière Hospital - Fernand Widal has developed a tool on a digital tablet or smartphone to evaluate cognitive functions: MemScreen. The purpose of this study is to validate this new neuropsychological test on tablet compared to the neuropsychological reference tests.
