Research is currently being conducted into it: 

Mental Space and Depression (MSP-D)

The method MSP-D is developed by Lucas Derks and is based on NLP and Mental Space Psychology.

The experience of depression is often psychologically associated with “dark matter”, or darkness. Psychologists take this to be a metaphor, but clients often experience their depression as something “tangible”, like a “dark cloud. If we take these metaphors as something real, we can start working with them and make them “lighter.”

The experience of “darkness” in mental space suggests a process of repression, or suppression, that clients are unable to handle; of something they have given up in their lives and about which they feel hopeless. Just “being aware” of these so-called “dark zones” has no therapeutic value in itself. It is a matter of retrieving the repressed feeling that is hidden behind the client’s dark zones, and to transform it. 

By shedding light on the metaphorical darkness of depression, as on a dark cloud, mental space is affected in such a way that people can better handle their “dark zone” of depression because it often gets smaller and lighter and changes place and shape. Consequently, it becomes easier for the client to look “behind the black cloud of darkness” in such a way that the true problem behind the depression becomes perceptible. So the gist of the treatment is to discover and transform the repressed feeling hidden behind ‘the dark zones,’ so that people can experience relief and “enlightenment.” 

Mental Space Psychology-Food and Overweight Panorama (MSP-F.O.P.)

The method MSP-F.O.P. is developed by Jacqueline Heemskerk-Scholten in 2017 under the supervision of Dr. Lucas A.C. Derks and is based on Mental Space Psychology combined with NLP. 

By letting people experience their foods in the mental space, we can quickly make a diagnosis. In general, you can say that food that is experienced close to the mental space is eaten faster. 

People with a healthy diet, experience foods at a greater distance. 

Old bad eating patterns can easily be changed in the mental space to healthier eating patterns. 

People with binge eating will experience food very close and can hardly move it. NLP techniques can be used to solve underlying causes. After that, the food is easy to move. 

Obesity can also be observed in the mental space, both associated and dissociated. By letting clients experience this consciously and confronting it with the fact that they cannot remove it from their mental space, they are more open to discover what is the cause of their obesity. The next step is to make this problem visible. Doing this in the mental space immediately shows what the problem is. Once the problem has been solved, you can let go of the excess weight, both in the mental space and in real life.
