Auditory Sensory Meridian Response: comments requested, anecdotes, use in prevention/treatment





Excerpt from Wikipedia entry:

Contemporary history



The contemporary history of ASMR began on 19 October 2007 when a 21-year-old registered user of a discussion forum for health-related subjects at a website called 'Steady Health',[22] with the username 'okaywhatever', submitted a post in which they described having experienced a specific sensation since childhood, comparable to that stimulated by tracing fingers along the skin, yet often triggered by seemingly random and unrelated non-haptic events, such as 'watching a puppet show' or 'being read a story'.[23]

Replies to this post, which indicated that a significant number of others experienced the sensation to which 'okaywhatever' referred, also in response to witnessing mundane events, precipitated the formation of a number of web-based locations intended to facilitate further discussion and analysis of the phenomenon for which there was plentiful anecdotal accounts,[12][24]yet no consensus-agreed name nor any scientific data or explanation.[17]

The Devil’s Needle 1916 (Some holiday viewing pleasure ?)

“The Devil’s Needle stars silent goddess Norma Talmadge as a morphine-addicted artist’s model who sends a neurotic partner (Tully Marshall) down a path of moral deterioration.”

ASAM Weekly in the News

Free subscription,

The weekly performs a consolidator function, akin to this blog but more focused.
These “in this issue” bullets are links to other news sources.
Not necessarily peer-reviewed material.
The assertions in these bullets are not those of the weekly’s editor.
These headlines might represent modern journalism in action, with a click bait function.








(Notice the three key facets and the relative prominence and ordering, reflective of American but not all of western neuropsychiatry): (1) neuroadaptation, (2) disturbances of behavior (compulsion-like ‘inability to abstain consistently, dysfunction of behavioral control), and (3) disturbances of the mental life (obsession-like ‘craving’ and ‘dysfunctional emotional response’). Also disengaged from non-American western traditions of theoretical psychopathology (as a science), the interdependent facets of socially maladaptative behavior have been moved into the foreground. An alternative is multi-axial thinking within theories of (1) how things break down and go against life form viability and successful survival of the species and of the individual (survivorship of the individual, to the extent it can be usefully separated from reactions of other players in the individual’s social fields, as well as the social context) and the (2) the separable but interdependent responses of natural raters in social fields (e.g., interpersonal strife when the individual does not live up to expectations of the natural raters in these social fields). The theory that these facets are exchangeable manifestations of one another, with an underlying single latent dimensional structure, has influenced the measurement model such that diagnosis now requires little more than counting up what is thought to be exchangeable. Alternative theoretcal models specify value in maintaining a distinction between the ‘disease’ or ‘disorder’ as can be observed with social field/context held constant (which requires a separable measurement), versus manifestations that are interdependent but conceptually kept separate despite the interdependence and shared origins. 

To think about a clear example in medicine where we have another strong independendence but a compelling rationale to maintain separation, consider systolic versus diastolic blood pressure, where the inter-correlaion often shows up with correlation coefficients well above 0.65, and shared variance components due to common origins. Irrespective of the biometrical correlation and covariance structure, the conceptual theory of modern medicine leads us to specify a measurement model for hypertenion diagnosis that separates the systolic dimension of arterial stiffness (change in SBP with DBP dimension held constant) from the diastolic dimension of arterial compliace (change in DBP with SBP dimension held constant).
