This clinical study aims to examine the effectiveness of a 12-week modified ketogenic diet (MKD) intervention, especially on cognitive functions, in individuals diagnosed with amnestic-mild cognitive impairment (aMCI) and to compare the effects of control groups (passive or active). Accordingly, a sample of 36 older adults aged 65-80 years diagnosed with aMCI will be randomized into 3 different groups: passive control (without any intervention), active control (MIND: Mediterranean-DASH Intervention for Neurodegenerative Delay diet) or intervention (MKD). They will be monitored according to targeted criteria throughout the 12-week study protocol. The main questions this study aims to answer are: - Does a 12-week MKD intervention improve cognitive functions in aMCI? - Does the effectiveness of the 12-week MKD intervention in aMCI (i.e., in terms of cognitive function, physical and functional measures, or metabolic/inflammatory biomarkers) differ from control groups? Expected from participants during the study protocol: - Participants assigned to the passive control arm are expected to come to the research center at the beginning (week 0) and end (week 12) of the protocol and participate in evaluations. - Participants assigned to the active control (MIND diet) or intervention (MKD) arm are expected to adhere to assigned dietary therapy, keep a weekly food diary, and have weekly phone calls or online meetings with the dietitian to follow up on the diet. These participants assigned to the diet groups are expected to come to the research center at weeks 0, 4, 8, and 12 to participate in the evaluations.
Postoperative cognitive deficit and its connection with surgery and general anesthesia were first mentioned in the literature in 1955 by Bradford. Cognitive disorders in the postoperative period are postoperative delirium (POD) and postoperative cognitive dysfunction (POCD). POD is an acute dysfunction in cognition, which did not exist preoperatively. Attention deficit disorder is the main symptom of POD and refers to the inability to direct, focus, maintain, or shift attention. Memory impairment, disorientation, or perceptual disturbances may also be present. Cognitive capacity changes in POD patients develop and fluctuate in the first few days after surgery. Unlike POD, there is no formal definition for POCD. Based on data from the existing literature, it is defined as newly diagnosed cognitive deterioration that occurs after surgery. The diagnosis of POCD should be based on pre- and postoperative screening with appropriate psychometric tests. Risk factors for the development of POCD include those related to the surgical procedure, anesthesia, or the patient himself. Compared to less invasive and shorter operations, there is a higher risk of developing POCD after major, invasive, and long-term operations. Additional risk factors are intraoperative (intraoperative bleeding, perioperative transfusion treatment, hypotension) and postoperative complications (respiratory insufficiency, pneumonia, atelectasis, bronchospasm, bronchopleural fistula, and pulmonary edema). Presurgical optimization (Prehabilitation) is a widespread concept that aims to improve the general condition of the patient or optimize comorbidities before major surgery. Prehabilitation is primarily focused on improving physical ability and nutritional status, but it is developing in the direction of a multimodal approach that includes measures to reduce stress and anxiety. Psychological factors are increasingly recognized as an essential element of prehabilitation and are often added to prehabilitation programs. Older patients, who meet the diagnostic criteria for frailty and are at risk of developing postoperative complications such as cognitive function disorders are increasingly undergoing lung resection. These complications can affect the outcome and speed of postoperative recovery.
In the case of spinal cord injury, rehabilitation is particularly focused on motor skills. Non-motor impairments such as thinking difficulties did not receive a lot of attention to date. In this research project, the investigators want to find out how thinking difficulties become noticeable in the brain with spinal cord injury. Participation procedure: Participants who take part will be asked to come to an examination once. The duration of the examination is between 2 and 2.5 hours (including around 55 minutes in the magnetic resonance imaging scanner, including preparation and follow-up).
This study aims to validate the Lithuanian version of the Brief Negative Symptoms Scale, Calgary Depression Scale for Schizophrenia, and Schizophrenia Cognition Rating Scale in a Lithuanian sample. This will be done by comparing results obtained from the Brief Negative Symptoms Scale, Calgary Depression Scale for Schizophrenia, and Schizophrenia Cognition Rating Scale with results obtained from the Positive and Negative Symptoms Scale, the Montgomery Asberg Depression Rating Scale, and the Montreal Cognitive Assessment test.
Hereditary spastic paraplegia type 4 is the most frequent mutation of hereditary spastic paraplegias. It is commonly described as pure, with progressive weakness of the lower limbs, pyramidal syndrome and vesico-sphincter disorders. However, cognitive disorders have been reported for over 20 years, but remain poorly characterized.
The present study is testing spermidine treatment in elderly patients with coronary artery disease. The study is a randomized, double-blind, placebo-controlled, two-armed, parallel-group, single centre, clinical study.
The main objective is to investigate whether administration of probiotics to patients with mild Alzheimer's Disease (AD) reduces neuroinflammation, improves cognitive function and modifies neurophysiological measures, compared to a patient group that receives placebo (no active probiotics).
To evaluate the dose-response of relevant blood biomarkers to remote ischemic conditioning in patients with age-related cerebral white matter hyperintensities on MRI, in preparation for a subsequent larger efficacy trial.
This study is a group controlled clinical trial. Parallel study, patients aged 40-80 years, with Parkinson disease. Twelve sessions, three times a week, for 30 minutes. Training will consist of Transcranial Direct Current Stimulation linked to tredmill training, in 3 blocks of 7 minutes, and adicionally to the Experimental Group, dual-task cognitive-motor exercises, simultaneously. The investigators will use the folowwing instruments: Auditory Stroop Test, Trail Making Test, Montreal Cognitive Assessment, Timed-up-and-go ST and DT, UPDRS II and III and Eletroencefalography (EEG). The objective is to examine cognitive alterations on PD pacients due to intervention and the relationships between baseline outcomes in responders and non-responders to therapy.
