Ketamine therapy has a swift short-term effect on reducing symptoms of depression and suicidal thoughts, according to a review of all the available evidence.
A systematic review led by the University of Exeter and funded by the Medical Research Council analysed evidence from 83 published research papers. The strongest evidence emerged around the use of ketamine to treat both major depression and bipolar depression. Symptoms were reduced as swiftly as one to four hours after a single treatment, and lasted up to two weeks. Some evidence suggested that repeated treatment may prolong the effects, however more high-quality research is needed to determine by how long
Similarly, single or multiple doses of ketamine resulted in moderate to large reductions in suicidal thoughts. This improvement was seen as early as four hours following ketamine treatment and lasted on average three days, and up to a week
.
Lead author Merve Mollaahmetoglu, of the University of Exeter, said: “Our research is the most comprehensive review of the growing body of evidence on the therapeutic effects of ketamine to date. Our findings suggest that ketamine may be useful in providing rapid relief from depression and suicidal thoughts, creating a window of opportunity for further therapeutic interventions to be effective. It’s important to note that this review examined ketamine administration in carefully controlled clinical settings where any risks of ketamine can be safely managed.
For other psychiatric disorders, including anxiety disorders, post-traumatic stress disorders and obsessive-compulsive disorders, there is early evidence to suggest the potential benefit of ketamine treatment. Moreover, for individuals with substance use disorders, ketamine treatment led to short-term reductions in craving, consumption and withdrawal symptoms.
Published in the British Journal of Psychiatry Open, the review synthesises the evidence from a growing field of research into the potential benefits of ketamine for conditions for which there are limited effective treatments. The review included 33 systematic reviews, 29 randomised control trials, and 21 observational studies.
Ketamine’s effects on depressive symptoms and suicidal thoughts are supported by numerous systematic reviews and meta-analyses, which provide an exhaustive overview of research in a given topic. These are considered to have the highest strength of evidence compared to other types of studies, increasing confidence in the evidence for ketamine’s antidepressant and anti-suicidal effects.
However, ketamine’s therapeutic effects for psychiatric conditions other than depression and suicidal thoughts are based on small number of studies that did not randomise people into different treatment arms. These effects require replication in larger randomised placebo-controlled trials, which are considered as gold standard.
The authors noted a number of difficulties in the research field, which they recommend that future studies should seek to address. One factor is the bias created because participants realise they have been given ketamine, rather than a saline solution. Senior author Professor Celia Morgan, of the University of Exeter, said: “We’re finding that ketamine may have promising benefits for conditions that are notoriously hard to treat in clinic. We now need bigger and better-designed trials to test these benefits. For example, due to ketamine’s unique subjective effects participants may be able to tell whether they have been given ketamine or a saline solution as the placebo, potentially creating an expectation about the effects of the drug. This effect may be better controlled by having active placebo-controlled trials, where the control group receives another drug with psychoactive properties.”
A number of questions remain unanswered in the research field, including the optimal dose, route of administration and number of doses of ketamine treatment. There is also a need for further research on the added and interactive benefit of psychotherapy alongside ketamine treatment.
Additionally, the importance of ketamine’s acute subjective effects in its therapeutic benefits has not been fully explored. More research is also needed on how to optimise participants’ preparation for ketamine treatment and the setting in which ketamine treatment is delivered.
The research involved collaboration with the University of British Columbia, and received support from the Society for the Study of Addiction. The paper is entitled ‘Ketamine for the treatment of mental health and substance use disorders: a comprehensive systematic review’, and is published in the British Journal of Psychiatry Open.
Anxiety is one of most prevalent mental health disorders, with 1 out of 14 people around the world being likely affected. Leading up to conditions such as depression, increased risk for suicide, disability and requirement of high health services, very few people who often need treatment actually receive it. In her talk “How to cope with anxiety”, Olivia Remes of the University of Cambridge will share her vision on anxiety and will unravel ways to treat and manage this health disorder.
Arguing that treatments such as psychotherapy and medication exist and often result in poor outcome and high rates of relapses, she will emphasise the importance of harnessing strength in ourselves as we modify our problem-coping mechanisms. Olivia will stress that by allowing ourselves to believe that what happens in life is comprehensive, meaningful, and manageable, one can significantly improve their risk of developing anxiety disorders.
Those who care for older adults suffering with memory loss and other cognitive impairments can significantly reduce their depression, stress, and anxiety by focusing on what is going on at the moment and engaging in mindfulness therapy, according to new Rutgers research.
The study, published in Aging & Mental Health, examined the feasibility, acceptability, and usefulness of Mindfulness Coach, a mobile application designed to teach people how to practice mindfulness.
“Caregiving can be extremely stressful and time consuming. Caregivers don’t always have time to seek out the services that they may need, like therapy,” said Elissa Kozlov, instructor in the Department of Health Behavior, Society, and Policy at the Rutgers School of Public Health. “However, our study has indicated that mHealth strategies, such as the Mindfulness Coach app, fits well into caregivers’ busy lives and has the potential to improve their mental health and wellbeing.”
Unpaid caregivers, who are often relatives and friends, are the ones who usually provide the largest portion of support to those who require medical assistance. Since this care if often for a prolonged period, they can experience a higher level of stress and anxiety.
Mindfulness therapy, the technique behind the Mindfulness Coach App, provides stress and anxiety management through psychoeducation, guided meditation, and mindfulness exercises to reduce symptoms of stress and depression. It was created by a team at the National Center for PTSD Research at the Department of Veterans Affairs.
The researchers, interested in determining whether mindfulness therapy would have comparable positive implications on caregivers of older adults with cognitive impairments, studied a sample of family caregivers over eight weeks to assess anxiety and depression levels, caregiver burden, application user experience and satisfaction, and total application usage time.
They found that as caregivers engaged more with the app, symptoms of anxiety, stress, depression, and caregiver burden decreased.
“The mobile application provides patient centered treatments to individuals with increased responsibilities and stressors,” adds Paul Duberstein, chair and professor in the Department of Health Behavior, Society, and Policy at the school. “The Mindfulness Coach application is a user friendly, feasible option for this population of caregivers and has yielded positive results.”
The results of this study suggest mobile health interventions can positively impact future mental health treatment options for patients through scalability and accessibility.
