The case for the rapprochement of neurology and psychiatry

Given the considerable overlap between these subspecialities, there has been a resurgence of interest and debate relating to neuropsychiatry in academia over the last decade.
Most of this work argues for a rapprochement of neurology and psychiatry, forming a specialty above and beyond a subspecialty of psychiatry. For example, Professor

 by training, has summarized the argument for reunion: "the separation of the two categories is arbitrary, often influenced by beliefs rather than proven scientific observations. And the fact that the brain and mind are one makes the separation artificial anyway." These points and some of the other major arguments are detailed below.

Mind/brain monism

Neurologists have focused objectively on organic

Mind
The concept of mind is understood in many different ways by many different traditions, ranging from panpsychism and animism to traditional and organized religious views, as well as secular and materialist philosophies. Most agree that minds are constituted by conscious experience and intelligent...

. This antipodal distinction between brain and mind as two different entities has characterized many of the differences between the two specialties. However, it is argued that this division is simply not veridical; a plethora of evidence from the last century of research has shown that our mental life has its roots in the brain

. Brain and mind are argued not to be discrete entities but just different ways of looking at the same system (Marr, 1982). It has been argued that embracing this mind/brain monism

 is important for several reasons. First, rejecting dualism logically implies that all mentation is biological and so immediately there is a common research framework in which understanding—and thus treatment—of mental suffering can be advanced. Second, it removes the widespread confusion about the legitimacy of mental illness: all disorders should have a footprint in the brain-mind system.

In sum, one reason for the division between psychiatry

 was the difference between mind or first-person experience and brain. That this difference is artificial is taken as good support for a merge between these specialties.

Causal pluralism

Another broad reason for the divide is that neurology

 (Becker, 2004). Another example is schizophrenia

, the risk for which may be considerably reduced in a healthy family environment (Tienari et al., 2004).

Secondly, it is argued that this augmented understanding of etiology will lead to better remediation and rehabilitation strategies through an understanding of the different levels in the causal process where one can intervene. Indeed, it may be that non-organic interventions, like cognitive behavioral therapy (CBT), better attenuate disorders alone or in conjunction with drugs. Linden's (2006) demonstration of how psychotherapy

 is a pertinent example of this and is encouraging from a patient perspective as the potentiality for pernicious side effects is decreased while self-efficacy is increased.

In sum, the argument is that an understanding of the mental disorders must not only have a specific knowledge of brain constituents and genetics (inside-the-skin) but also the context (outside-the-skin) in which these parts operate (Koch and Laurent, 1999). Only by joining neurology and psychiatry, it is argued, can this nexus be used to reduce human suffering.

Hitherto psychiatric disorders have organic basis

 caused by sexual repression. However, starting with the efficacy of neuroleptic drugs in attenuating symptoms (Shapiro, Shapiro and Wayne, 1973) the syndrome has gained pathophysiological support (e.g. Singer, 1997) and is hypothesized to have a genetic basis too, based on its high inheritability (Robertson, 2000). This trend can be seen for many hitherto traditionally psychiatric disorders (see table) and is argued to support reuniting neurology

Better management model

Schiffer et al. (2004) argue that there are good management and financial reasons for rapprochement.

 and should thus be kept separate (e.g. Baughman and Hovey, 2006). On this issue, it is worth remembering that research into the neural correlates of psychiatric disorders is in its infancy: the answers may still be to come. One reason why they may not have been found so far is that complex mental disorders may result from minute and intricate brain-wide damage and complicated gene-environment interactions, which are only beginning to be understood. Disorders may not exist as tidy, localized neurodysfunction or genetic abnormalities but multi-factorial brain-wide disorders with complex interactions between environment and genetics (e.g. Green, 2001). Such distributed dysfunction may not be resolvable in the living brain with current technology. E.g. disparate behavioral disorders have been linked to identical neurodysfunction with imaging but show significant organic differences following neurohistological analysis (Rempel–Clower et al., 1996). Where physiopathology is extremely small and distributed or neural tissue is actually healthy it may be the disturbed information-processing that should be studied. E.g. Bell, Halligan and Ellis' (2006) work on cognitive deficits in delusions.

Thus the reasons for the initial division are argued not to be useful or real ones. The two specialties are both dealing with disorders of the same system. Biological psychiatry and behavioral neurology show how the boundaries are being blurred. It is argued that there can be no objection to a reunion on philosophical or scientific grounds.
