Despite developments in neuroscience that provide “a way to study schizophrenia in vivo … efforts to understand the neurobiological bases of the clinical symptoms that the diagnosis is based on have been largely unsuccessful.” Small samples, questionable reliability and validity of measurements, medication confounds, failure to distinguish state and trait effects, correlation-causation ambiguity, and the absence of compelling animal models are among the obstacles to finding “the elusive correlation” between neurobiology and symptoms, according to this article in Frontiers in Human Neuroscience.

What? How can this be? We’ve been told for years that we’re on the cusp of great discoveries! Thomas Insel himself touts genetics as the future for understanding mental illness ( he also admitted that theories based on chemical imbalances were far to simplistic and reductionistic…about 50 years too late).
I know this is a small thing, but I’m just not convinced that studying the brains of rats or mice will shed any light on the human suffering, trauma, love, disappointment, etc.
I know mice get stressed when someone moves their cheese but come one!

I know, truly shocking! And it seems only a few years ago we were told that it turns out that schizophrenia is 70% genetic and 30% down to environment – and in such confident tones.
What is a boy to make of all this?
I hear that there is going to be another huge sum put into researching the genetics of mental illness though, so maybe everything will turn out all right in the long run? (huge English Irony alert by the way).

January Schofield is probably the best neurobiological case of her condition. There is no doubt that she was born as she is.
When I look at pictures of Jani, her eyes and frazzled hair make me think she’s got some sort of serious malnutrition or other deficiency or deprivation.
