Human depression research, in general, could be done using humans or human-based methods.
Relevant methods for identifying potential human antidepressants include human platforms such as:
- Mathematical or computer modelling of human systems. IBM Watson for Drug Discovery in the US analyses millions of documents and synthesises multiple sources of information to show connections and relationships among genes, drugs and diseases.
- Drug-repurposing programmes, such as Vanderbilt University’s Accelerating Drug Discovery & Repurposing Incubator, which is based on human genetics.
- Epidemiology, the study of naturally occurring disease and health in human populations.
- In vitro research which involves procedures in a controlled environment outside of a living organism. For example, using cell-based tests and tissue models to assess the safety of drugs and chemicals.
Real-life examples of human psychological research using non-animal-based methods:
- Researchers in China and elsewhere are using induced pluripotent stem cells to establish cell lines that can be used for research into neuronal disorders. Read more about this here.
- Electronic medical records and wearable devices allow the collection of real-time data from human patients. This can utilise machine learning to generate individualised plans for patients undergoing treatment. Read more about this here.
- A research group at the D’Or Institute for Research and Education in Brazil is using a human cerebral organoid model specifically to study human depression and the effects of psychoactive substances. Read more here.
- At the University of California in San Francisco, researchers continuously recorded brain activity in human volunteers and were able to link changes in mood to specific patterns of brain activity. The study authors say, “The findings have scientific implications for our understanding of how specific brain regions contribute to mood disorders, but also practical implications for identifying biomarkers that could be used for new technology designed to treat these disorders.” Read more here.
It is important to note that the Forced Swim Test simply doesn’t work, therefore continuing to use it is senseless. If a test doesn’t work, it should be abandoned immediately, and efforts should go into finding a viable research method that will create real results.
If time and resources weren’t being wasted on fruitless research methods, such as the Forced Swim Test, then non-animal methods would be even more advanced than they currently are and more scientists would be utilising them. Contemplate the proverb “necessity is the mother of invention”. When the need for something becomes essential, we are forced to find ways of getting or achieving it. Therefore, banning the Forced Swim Test would not only help animals, but it would also create a large incentive for researchers to establish additional and improve existing viable replacement methods to help more people than the current fundamentally flawed method ever could.
Examples of human-relevant depression research in New Zealand:
- The Nutrients for Mental Health, Anxiety and Depression (NoMAD) Trial
The aim of this study is to find out if micronutrients have any effect on reducing the signs of depression in humans. The researchers have made it clear that medications work for some people and can save lives, but supplements containing micronutrients could be a less risky option to try out first in some cases. Find out more here.
- The NUTRIMUM Study
The aim of this study is to find out if a vitamin and mineral (micronutrient) supplement can improve low mood and anxiety in pregnant women. Find out more here.
Many different surveys have been conducted in New Zealand, involving large groups of people suffering from depression (epidemiology). For example:
- In my life antidepressants have been…’: a qualitative analysis of users’ diverse experiences with antidepressants.
This study involved 1747 New Zealanders who use antidepressant treatments answering a survey about their experience of antidepressants.
- Adverse emotional and interpersonal effects reported by 1829 New Zealanders while taking antidepressants.
This study involved 1829 New Zealanders who had been prescribed antidepressants in the past five years filling in an online survey about experiences with, and beliefs about, antidepressants.
Other examples of NZ-based, human-relevant research on depression:
- Patient predictors of response to cognitive behaviour therapy and schema therapy for depression.
- Clinical response to treatment in inpatients with depression correlates with changes in activity levels and psychomotor speed.
- Activation therapy for the treatment of inpatients with depression – protocol for a randomised control trial compared to treatment as usual.
- Protective Effect of CRHR1 Gene Variants on the Development of Adult Depression Following Childhood Maltreatment.
- Life stress, 5-HTTLPR and mental disorder: findings from a 30-year longitudinal study.
Help stop the cruel and invalid Forced Swim Test from hurting any more animals in New Zealand:
- Send a message to Victoria University, asking them to commit to no longer using this test.
- Donate to the Forced Swim Test campaign.
