Ketamine Treatment Options in Austin, TX

Plain Language Summary: This study is a clinical trial to see if ketamine can help treat symptoms of Long COVID, especially fatigue and problems with thinking clearly (often called "brain fog"). Long COVID is a condition that affects people even after they have recovered from COVID-19, causing ongoing health issues like tiredness, memory problems, and difficulty concentrating. Right now, there are very few treatments available for these symptoms, and many people are looking for new options to feel better. What is the study trying to find out? Does ketamine help reduce fatigue and improve thinking skills in people with Long COVID? Does ketamine improve overall quality of life and mental health for people with Long COVID? Is ketamine safe and well-tolerated for people with Long COVID? How does ketamine affect the body's biological processes, like inflammation and brain function? How will the study work? The study will include 20 adults between 18 and 65 years old who have Long COVID symptoms like fatigue or brain fog. Participants will first meet with researchers to answer health questions, take surveys about their symptoms, and do tests to check their thinking skills. Some participants will also have a brain scan (MRI) and give a blood sample to look at markers of inflammation. Participants will then receive four ketamine treatments over two weeks at a specialized clinic. The ketamine will be given as an injection, with the dose slightly increasing during the treatment period. After six weeks, participants will return for follow-up tests to see if their symptoms have improved. This includes repeating the surveys, thinking tests, and for some, another MRI and blood test. Why ketamine? Ketamine is a medicine originally used for anesthesia but has also been found to help with depression and other mental health issues. Researchers think it might help with Long COVID symptoms because it can reduce inflammation in the brain and improve how the brain functions. People with Long COVID often have signs of inflammation and changes in brain chemicals, which ketamine might help balance. What are the potential benefits? Participants might experience less fatigue and clearer thinking after ketamine treatment. They could also feel better overall in terms of mood and quality of life. Since ketamine can work quickly, some people may notice improvements shortly after starting the treatment. What are the risks? Ketamine can cause side effects like feeling dizzy, anxious, or having an unusual sense of reality (sometimes called dissociation). It may also cause temporary increases in blood pressure or heart rate. All treatments will be carefully monitored by healthcare professionals to ensure safety. Who can participate? Adults aged 18-65 with Long COVID who have significant fatigue or thinking problems can join. People will not be able to participate if they have certain health conditions like severe heart disease, uncontrolled high blood pressure, or a history of severe mental health disorders. Why is this study important? Long COVID affects millions of people, and many are struggling to find treatments that work. This study is one of the first to explore ketamine as a potential treatment for Long COVID symptoms. If ketamine helps, it could lead to more research and eventually new treatment options for people living with Long COVID. Read Less

The purpose of this study is to compare the efficacy and safety of switching treatment-resistant depression (TRD) participants from a prior antidepressant treatment (to which they have not responded) to either intranasal esketamine plus a new oral antidepressant or switching to a new oral antidepressant plus intranasal placebo.
