Both have elements of truth and both revolve around the idea that the problem is either best understood or not understood at all through the lens of the biomedical model  And, that the lack of or insufficiency of mental health is based on some sort of intrinsic but faulty brain function - which one camp poses as a disease and the other as a disorder - a distinction without substantive difference.

Instead, envision how differently one conceptualizes behavioral (which includes mental) dysfunction if one acknowledges the differences between “mental disease” (the psychoses) and “mental disorder” (the neuroses) as follows:

The first brain is, to varying extents, constitutively incapable of working any better.

The latter is, to varying extents, not being utilized in the most effective fashion - even though it is constitutively capable of doing so.

The result of such apprehension is that there are both mental diseases and mental disorders (that are not per se diseases).

Admittedly, we are poorly prepared to explain in full the etiology and processes involved in the psychoses or broken brains.

And, admittedly, there is an excess of attention to and agreement about the symptomatic content of the neuroses and far too little consensus about their underlying process/es.

From my perspective as a student of the processes of disease, that latter sentence is why the union of The One Divide Philosophy and the UTUA is so admirably important.  The One Divide Philosophy provides an illuminating account and categorization of the processes underlying the genesis of neuroses - using the brain less than maximally effectively.  In complementary manner, the BPA Power/Threat/Meaning Framework contributes focused attention on the constructional content of the genesis of neuroses.  Together, these two depictions furnish an enlightening and liberating paradigm by which to apprehend the nature of “the lack of mental health” in the case of both neuroses and psychoses - though, admittedly, in the case of the broken brain,” the attention doesn’t really look at the underlying problem/s upon which the “broken brain” is based.

Nonetheless, {The One Divide Philosophy + UTUA} paradigm is a logarithmic step forward in understanding the nature and treatment of those afflicted with less than satisfactory mental health - whatever name is applied to such infirmity.  As well, is a boon to all mens sanatores adunt (mind healers) - no matter their academic roots.
