Cognition Disorder

The purpose of this study is to investigate neurocognitive mechanisms underlying response to intervention aimed at enhancing, and remediating weaknesses in, numerical skills in children, including those with mathematical learning disabilities (MLD).

The goal of this study is to learn whether a videoconference-delivered CBT-I program (REPAIR Sleep) can improve sleep and psychological well-being in caregiver-PLwD dyads. The main questions it aims to answer are: * Does REPAIR Sleep improve insomnia severity and other sleep outcomes? * Does REPAIR Sleep improve psychological outcomes such as mood, stress, and quality of life? Researchers will compare REPAIR Sleep with Healthy Living to see whether REPAIR Sleep leads to greater improvements. Participants will: * Attend five weekly virtual sessions * Complete sleep diaries and questionnaires * Wear an actigraphy device * Complete follow-up assessments over 9 months

Cancer is among the leading causes of morbidity and mortality worldwide, profoundly affecting patients' lives at every level, and its psychological and psychiatric impacts remain a major concern. Psychiatric disorders are frequently observed in cancer patients. Nevertheless, they were also underdiagnosed, with a consequent undermining possible interventions. Still, psychiatric disorders in cancer patients are not merely secondary complications but may actively contribute to poor oncological outcomes. The pathophysiology of cancer-related psychiatric disorders is multifactorial and is related to several neuropsychological and neurobiological factors. Specifically, the production of cytokines associated with cancer appears to play a role in the development of depression. Tumours trigger an inflammatory response that leads to the release of pro-inflammatory cytokines. These cytokines influence central nervous system function and disrupt the regulation of the HPA axis, contributing to psychological symptoms such as depression, fatigue, sleep disturbances, and appetite loss. Moreover, psychiatric symptoms in cancer patients are often accompanied by neuropsychological alterations including deficits in memory, executive function, and attention. Compared to other individuals with psychiatric disorders, cancer patients may experience more severe cognitive impairments which can be exacerbated by cancer treatments, including surgery, chemotherapy, and radiotherapy. These treatments stimulate cytokine production by nearby non-cancerous cells and immune cells activated in response to treatment-induced cell death, thereby driving systemic inflammation. Cancer profoundly affects not only patients but also their families, who often bear the emotional and caregiving burden. Being close to a loved one with cancer can lead to significant psychological distress, including anxiety and depression, among family members and caregivers. The ripple effects of this burden underscore the need for a holistic approach to mental health in oncology. Given the background presented so far, identifying and managing psychiatric comorbidities in oncological patients and their families is crucial. This multifaceted interplay between cancer and psychiatric disorders necessitates a comprehensive, interdisciplinary approach to understanding, diagnosing, and treating these conditions effectively.

This study intends to evaluate the feasibility and the effectiveness of an innovative and integrated nutrition-based intervention addressing key modifiable risk factors for dementia while meeting participants' preferences for nutrition-related sessions. The intervention will include lifestyle group sessions regarding nutrition education and physical activity, individualized cognitive training at home, as well as clinical nutrition consultations.

Anesthesia is a drug induced, reversible, comatose state that facilitates surgery and it is widely assumed that cognition returns to baseline after anesthetics have been eliminated. However, many patients have persistent memory impairment for weeks to months after surgery. Cardiac surgery appears to carry the highest risk of postoperative cognitive dysfunction (POCD). These cognitive deficits are associated with increased mortality, prolonged hospital stay and loss of independence. The investigators propose to investigate the role of Dexmedetomidine (DEX) in preventing long-term POCD after cardiac surgery and enhancing early postoperative recovery. It is anticipated that DEX will be the first effective preventative therapy for POCD, improve patient outcomes, and reduce length of stay and healthcare costs.

The goal of this clinical trial (Balanced-2 study) is to compare light to deep general anesthesia using widely available brain monitors, to see if 'light' anesthesia could reduce rates of delirium, cognitive decline, and disability in older adults undergoing major surgery. Delirium is the most common serious surgical complication, occurring in an estimated one in four older adults undergoing major surgery. Delirium causes significant distress to patients and family, and is associated with prolonged hospital stay, physical disability, progression to dementia-like illnesses, and discharge to long-term care. Between 10 - 30% of adults aged 70 years and above have surgery every year, and preserving brain health and wellbeing is an important priority during this time. Older adults (aged ≥65 years, or Indigenous, Pacific patients aged ≥55 years) undergoing major surgery with general anesthesia (excluding heart and brain surgery) and able to provide consent will be able to participate. Participants will be randomized to two groups - a lighter general anesthesia group and a deeper general anesthesia group using processed electroencephalography (a brain monitor that provides information on depth of anesthesia using brain waves). The anesthesiologist will titrate anesthetic drugs according to the brain monitor. Participants will be followed up to determine if they experience delirium after surgery, and longer term impact of delirium such as cognitive and physical decline will also be measured. If found to be effect, this simple, cheap, and widely available treatment could reduce disability, preserve brain health and wellbeing of many older adults undergoing surgery worldwide, and save millions in healthcare dollars.

VIRGIL is a monocentric interventional study aiming to investigate the effect of immersion in a virtual tilted room on modulation of the verticality representation (postural vertical \[PV\] and visual vertical \[VV\]), which in turn might affect body orientation (head and trunk). To this end, the investigators will conduct a within-person randomized trial including post-stroke patients and healthy participants.

The purpose of this study is to identify genes responsible for epilepsy, brain malformations and disorders of human cognition.

A study conducted in Finland discovered that a multidomain intervention, consisting of physical activity, nutritional guidance, cognitive training, social activities, and management of vascular risk factors, effectively decelerated cognitive decline in healthy older adults who were at an increased risk of cognitive decline. The HERITAGE study is a 2-year clustered randomized controlled trial (clustered-RCT) that explores the efficacy of a multidomain intervention among 1200 elderly residents with a higher risk of cognitive decline and dementia in Zhejiang Province, China
