Network-targeted Theta-burst Stimulation for Episodic Memory Improvement in Mild Cognitive Impairment

The purpose of this study is to see if stimulation of the brain can improve memory. The investigators will use a device called transcranial magnetic stimulation that can stimulate and activate a specific part of the brain that is important for memory. The study will enroll MCI subjects who will be randomly assigned to receive active or sham brain stimulation. 'Blinded' or 'sham-controlled' means that the subject will not know whether the treatment they receive is the active treatment or the non-active stimulation. In the 'sham' condition, the stimulator will turn on but will not actually be stimulating the target brain region.

Strengthening Neuro-Cognitive Skills for Success in School, Work and Beyond

For many Veterans, success in achieving goals at work, school and in other aspects of life are top priorities. The abilities to regulate attention, remember key information, and stay calm and on track are fundamental to this success. Unfortunately, Veterans who have experienced a traumatic brain injury (TBI) often struggle with these very abilities, and a number of barriers can make it difficult for them to access the help Veterans need. Tele-rehabilitation has the potential to overcome some of these barriers and increase access to care, enabling providers to better reach Veterans 'where they are' in their communities. This project will assess two different approaches to brain injury rehabilitation that seek to help Veterans build personal strengths to better accomplish their goals. Both approaches will be delivered remotely via tele-rehabilitation and augmented by digital apps to best support Veterans' learning in community settings outside the VA.

Ketamine vs Midazolam on Cognitive Function in Elderly in Elective Surgery Three-Months Postoperatively (ketaminvsMDZ)

Deterioration of posoperative cognitive function (DCPO) is an intermediate state between normal cognitive aging and dementia, defined as a cognitive alteration greater than expected for the patient's age and educational level, but which doesn't interfere with the activities of daily life, in its evolution it can lead to dementia or it can present reversal of the deterioration with return to a normal cognitive state, or a stabilization with permanence in a state of moderate alteration. In general, higher cognitive function can be affected by organic or functional problems, anesthetic-surgical, diseases associated with the elderly and / or chronic-degenerative comorbidities. Older patients who undergo regional anesthesia have special interest, the adverse cardiovascular effects, or prolonged sedation due to a pharmacokinetics that is altered by age, call special attention to reduce complications in the postoperative period. In 2010 at the Siglo XXI Hospital in Mexico City, the 68-year-old population attended was 30% of those with postoperative cognitive dysfunction 26% a week, and 10% persistence at 3 months. The DSM V recommends a neuropsychiatric, psychological and cognitive evaluation of the patient in the postoperative period, through tests such as the Mini Mental State Examination. sub-anesthetic doses of ketamine have been recently proposed to reduce the postoperative markers of inflammation, pain and opioids, in addition to having an antidepressant effect. There is a pharmacological rationale for using ketamine as a preventative measure against postoperative delirium based on its N-methyl-D-aspartate (NMDA) antagonism, It has the potential to protect against such neurological injury.

Wellbeing After Stroke (WAterS)

Stroke survivors face a range of mental health challenges adjusting post-stroke. There is a lack of treatment options and clinical psychologist workforce to deliver support. Acceptance and Commitment Therapy (ACT) has been used successfully in clinical services to improve wellbeing. The investigators worked with stroke survivors, health care professionals and researchers to develop group ACT therapy, specifically for stroke survivors, to be delivered using video calling (Zoom). Staff training and supervision programmes were also developed to equip Stroke Association workforce (paraprofessionals) to deliver ACT. The current study will recruit and train up to 10 paraprofessionals with some experience of supporting stroke survivors. The study aims to recruit up to 60 stroke survivors in the community who are at least 4 months post-stroke and experiencing distress adjusting to their stroke. The investigators aimed to make everything accessible for people with mild/moderate difficulties with thinking and communicating. Recruitment takes place across England, over a 12 month period. The study will test how feasible and acceptable it is to deliver our remote ACT intervention to stroke survivors, using a 'modified randomised consent' design that involves two levels of consent for stroke survivors: The first level is agreement to complete online measures of well-being every 3 months for up to 12 months (taking around 20 minutes), with the option to participate in groups. Those who don't opt for groups will not be treated but will be followed up about their wellbeing. Those who opt to attend groups will be randomly allocated to attend either the ACT intervention or an active control group, involving social support. Both groups involve 8 weekly sessions and homework. Data will be collected on how successfully the groups are delivered and how acceptable they are / how to improve them, through online surveys, feedback questionnaires and interviews.
