I believe that even conventional western medicine is realizing that the notion of a spectrum can apply to many conditions, not just a few, such as Autism Spectrum Disorder. Chronic lung disease, liver disease, dyslipidemias, and most most notably the spectrum of T2D, are all great examples of this. Maybe the future will be one where we can all be placed on a spectrum for many conditions, and use that information/proneness to recognize our own vulnerabilities to a host of mind and body conditions, and hence manage our lives better. RR Grinker wrote a very insightful book about that (Nobody’s Normal: How Culture Created the Stigma of Mental Illness), specific to psychiatry, his field, but with far reaching implications and suggestions for applications outside the realm of mental illness.
