Neuropsychotherapy News Mediros Clinical Solutions Edition 5 July 2011 The challenge to understand the Brain We live in exciting times! Almost daily we read about new discoveries in brain research—many with fascinating possibilities in terms of understanding the functions of the brain as well as opportunities for treatment. In this edition we focus on one of the most profound theories of the evolution of the brain—the Triune Brain model developed by American Neuroscientist Paul D MacLean. MacLean worked at the Yale Medical School and the Inside this issue: National Institute for Mental Health. His theory proposed that the brain is in reality three brains in one. These ―three brains‖ developed in sequence and inform each other in a unique way. Although modern neuroscience indicated some difficulties in the MacLean model there are also some significant implications for neuropsychotherapy that need to be considered. This model provides insight into the discussion regarding topdown or bottom-up approaches in therapy. Further, we comment on a study relating to sleep and depression and the experience of quality of life. From a neurobiological perspective the need for good sleep hygiene is one of the cornerstones of well being and needs to be effectively addressed in our therapeutic work. Enjoy the read!

We started in March this year with, what we thought, was a great readership number of just over 300 clinicians. This number quickly rose to 500 in April and in May it jumped further to nearly 700. Since the June edition we mailed out 1027 Newsletters with clinicians signing up on daily basis. We will endeavour to continue to run this as an independant, free, neuropsy- chotherapeutic newsletter aiming to serve the large community of practitioners in this field who wish to expand their body of knowledge. It also aims to provide information and guidelines to foster higher levels of efficacy in therapeutic practice. Lastly we aim to become a mouthpiece for our regional peer discussion groups that we are facilitating and hope they will (eventually) take a life of their own as soon as they are up and running— hopefully within a fewmonths! few months. We must recollect that all of our professional ideas in Psychology will presumably one day be based on an organic substructure Sigmund Freud “On Narcissism” Page 2 Neuropsychotherapy News 5 July 2011 The Triune Brain—Implications for Neuropsychotherapy Pieter J Rossouw (MClin Psych PhD) Between 1949 and 1990 neurologist Paul MacLean developed a groundbreaking theory of understanding brain development – called the triune brain (MacLean 1990). The triune brain is a model of development that consists of a Reptilian complex, the Paleomammilian complex and the Neomamillian complex. The reptilian complex Also known as the R-complex or ―reptilian brain‖, MacLean contended that this complex is the first to develop in the brain and is responsible for most basic species typical behaviours involving bodily functions breathing, heart rate control, etc. and handles basic motor planning, and basic affects including physiological aspects of aggression and anxiety. It involves the brainstem, pons and diencephalon. The Paleomammilian complex MacLean first introduced the term ―limbic system‖ to refer to the set of closely connected structures be- The Triune Brain model —Paul D MacLean The Neomamilian Brain (mental and cognitive reasoning—make sense of perceptions enable complex emotions) The Paleomamilian Brain (scans for novelty—keep system safe, refines basic affects— enable development of social emotions) The Reptilian Brain (regulate basic bodily functions, works instinctively, handles basic motor planning) tween the corpus callosum and the brainstem and upper brainstem areas. This complex includes the amygdala, hippocampus, thalamus, hypothalamus, septum and cyngulate cortex. MacLean indicated that these structures develop sequentially later than the reptilian complex and they refine basic affects and enables the development of social emotions and expanded memory functions (MacLean 1990). The Neomamillian complex This complex consists of the cerebral cortex, or neo cortex – found only in mammals. MacLean maintained that this is the most recent step in the evolution of the human brain – conferring the ability for language, abstract cognitive processes, sequential planning and perception. This complex has the ability to down regulate other functions if effectively activated. In terms of human evolution – MacLean maintained the reptilian complex precedes the other areas by millions of years and the Paleomammilian complex precedes the Neomamillian complex by millions of years. This bottom up development is profound in how the brain expresses itself up to this day. MacLean also indicated that human brain development happens in line with these three complexes (Newman 2009). Daniel Siegel shares the same theoretical approach – the primitive part of the brain develops first and is fully developed at birth, the Paleomammilian complex develops later and is semi developed at birth and the Neomamillian complex develops even later and is mostly undeveloped at birth. Page 3 Neuropsychotherapy News 5 July 2011 The implication of this theory is that the survival instinct is intact from birth, the emotional response to the survival instinct is active but its reaction to specific triggers is a learned response and the higher cognitive and emotional processing develops fully in interaction with its environment. This theory has far reaching implications on many levels as well as for therapeutic interventions (Lambert 2003). The neurodynamics of secure attachment on the one hand and insecure attachment on the other, indicates that the violation of security in the early months after birth will have significant implications on survival needs and cause disruptions on the most primitive complexes of the brain – the effect is physiological distress and even atrophy of critical brain areas as research clearly show. Current status of the Triune model Recent behavioral studies do not fully support the view of MacLean regarding the evolution of the brain. For example - birds have been shown to possess highly sophisticated cognitive abilities, such as the tool making of the Neo Caledonian crow and the languagelike categorization abilities of the African Gray Parrot. Structures of the limbic system, which MacLean contended arose in early mammals, have now been shown to exist across the whole range of modern vertebrates (Patton 2008). The "Paleomammilian" trait of parental care of offspring is widespread in birds and occurs in some fishes as well. Thus, like the basal ganglia, the evolution of these systems presumably dates to a common vertebrate ancestor. Finally, the third statement of the triune brain hypothesis, which is that the neocortex appears in modern mammals, seems not to be factually correct. All recent studies based on paleontological data or comparative anatomy evidences strongly suggest that the neocortex was already present in the earli- est emerging mammals. Although nonmammals do not have a neocortex in the true sense, their brains still make neuroanatomical connections with other brain structures and mediate similar functions. The MacLean Triune Brain model – usable or unusable? Does this mean the concepts of MacLean are faulty and unusable? It seems that although we have more sophisticated models of explaining brain functioning, the essence of MacLean’s model is that there is a sequence present in brain development and that this sequence has a profound effect on the pathogenesis of mental disorders and neural firing. We know without doubt that children are born with a fully active ―primitive complex‖ - brainstem and pons regions, as well as a fully developed limbic awareness but the response to external triggers needs to be learned in terms of what constitutes danger. These activities are activated long before frontal cortical structures are fully formed resulting in responses that, if unhealthy, need to be addressed (down regulated) in therapy. Further: PET scans clearly show the effect of looping activity on cortical blood flow which inhibits effective activation of frontal cortical systems. Implications for Neuropsychotherapy Implications for therapy favour a bottom up approach (instead of the cognitive model of a top down approach)– initially focussing on establishing good therapeutic alliance (safety) and physiological symptoms to down regulate unhelpful neurotransmitter firing (norepinephrine, corticotrophin releasing factor, corticotrophin hormone, adrenalin and cortisol) and up regulate serotonin flow, dopamine release and activation of the parasympathetic nervous system as well as addressing the scanning for novelty (danger) by the amygdala (Blackford et al 2010). Page 4 Neuropsychotherapy News 5 July 2011 This creates a safe positive environment for clients to explore new strategies (cognitive interventions) and behavioural change – establishment of new neural highways with effective limbic firing and less looping activities in the ACG (anterior cyngulate cortex) and OFC (orbito frontal cortex) (Hart 2011). Establishing these safety measures first enhances cognitive interventions further down the therapeutic process. A top down approach (cognitive model) implies an activation of the frontal cortical structures to down regulate the stress response, limbic firing and sub limbic structural activity (medulla and pons) to decrease the release of norepinephrine (among other stress hormones and neurotransmitters– CRF, ACTH, cortisol and adrenalin). The implication of this approach is that there is sufficient serotonin release to increase cortical blood flow to the left frontal cortex to activate the cognitive abilities effectively. It further implies limited looping activity limbic firing as well as enough emotional safety to activate these strategies. These are significant assumptions – especially in light of the fact that initially in the therapeutic process the pathology is fully present with limited (if any) effective skills to manage the presenting symptoms of distress – hence the need for therapeutic intervention. This maturation process indicates the benefit of a bottom up therapeutic approach which is linked with down regulation of stress related neurotransmitters and neural structures as a result of early activation (gene expression and early experiences in the first months post birth) and the need for up regulation of safety triggers (oxytocin release, attachment, up regulation of the parasympathetic nervous system, increased GABA release etc.) to maximise therapeutic outcomes.

Hart explains how the dichotomies of brain/mind, biology/experience, and nature/nurture hamper the development of a theory that is capable of fully embracing the complexity that characterizes human psychological development. An interactive, neurobiological and interpersonal perspective, she argues, will help develop a common basis for helping clients in therapy. Each chapter demonstrates and explores key aspects of the importance of attachment, and throughout, Hart reviews case stories from her own clinical practice, drawing from years of conducting psychological assessments of children, family interventions, individual therapy, and professional supervision assignments. As Hart explains at the outset, our brains are sculpted, neuron by neuron, in close interaction between genetic conditions and environmental stimulation, and thanks to their tremendous plasticity, they are capable of reorganization. In Part 1 she looks at children’s normal development, brain maturation, and the development of the various levels of mental organization in infants. She emphasizes the importance of interaction with the primary caregiver for the child’s neuroaffective development, including the formation of internal representations and mentalization capacity, and presents a model for levels of mental organization, or developmental stages when the nervous system undergoes qualitative changes with regards to personality development. Part II looks at attachment and relational disorders – including dysregulation patterns and misattuned communication – and offers a new preliminary understanding of psychopathology based on a neuroaffective and developmental perspective. Part III aims to integrate existing therapeutic approaches within a neuroaffective framework. Hart calls for a higher degree of precision in the methods of intervention related to symptom formation and therapy aimed at children and adolescents. She summarizes considerations concerning emotional attunement and its impact on the therapist-client relationship, and discusses a complex approach to therapeutic intervention based on a neuroaffective model. The book concludes with a look into a dynamic system with both family and environmental therapy. Part of the Norton Series on Interpersonal Neurobiology, The Impact of Attachment transforms complex neurobiological and behavioural theory into protocols that can be easily implemented by the practicing clinician.

Results show that people with a "normal" sleep duration of six to nine hours per night had higher self-reported scores for quality of life and lower scores for depression severity compared to short and long sleepers. These differences were statistically significant in all comparisons. Among patients who reported having perfect health, there were a higher percentage of normal sleepers, who also had significantly lower scores for depression severity compared to short and long sleepers with perfect health. "These results are important because they provide more information about the importance of getting enough sleep, which is usually six to nine hours per night," said principal investigator Dr. Charles Bae, neurologist at the Cleveland Clinic Sleep Disorders Center in Ohio. "People may already expect that their quality of life could be decreased when they do not get enough sleep, but they may not realize that sleeping too much can also have a negative impact." Bae and colleagues analyzed data from 10,654 patient records, which were collected from January 2008 to May 2010. Study subjects had a mean age of about 52 years. Quality of life was assessed using the EQ-5D questionnaire, a standardized measure of health outcome. The nine-item Patient Health Questionnaire was used as a screening tool for depression. Generalized estimating equations were used to account for multiple visits per patient, and a multivariable logistic regression model adjusted for demographic differences such as age, gender, race and marital status. Short sleep was defined as less than six hours per night, and long sleep was classified as more than nine hours per night. "It was surprising to see that sleeping less than six hours and more than nine hours is associated with a similar decrease in quality of life and increase in depressive symptoms," said Bae. "I thought that there would be changes in quality of life and degree of depressive symptoms for short and long sleepers, but did not expect that those changes would be similar in both groups." The American Academy of Sleep Medicine reports that individual sleep needs vary. However, most adults need about seven to eight hours of nightly sleep to feel alert and well rested during the day. ScienceDaily (June 15, 2011) Comment This study is consistent with research indicating the need for people to go through all four sleep cycles for effective hippocampal discharge. Hippocampal discharge happens during fast ripple oscillations—REM sleep and is crucial in memory consolidation linked with the frontal cortex. The fourth sleep cycle is normally the longest with potentially the most significant effect on hippocampal discharge— missing this sleep cycle (not enough sleep on regular basis) effects good hippocampal functioning and may result in agitation (over active limbic structures), concentration lapses (non effective hippocampal functioning) and lack in problem solving skills (under activation of left pre frontal cortical functioning and reduced cortical blood flow. (PJR) Page 7 Neuropsychotherapy News 5 July 2011 Upcoming Neuroscience Workshops As mentioned in the previous newsletter we are running two workshops this year, the first of which, The Brain and Anxiety, has been running for several months now. Since our last edition we ran the Brisbane and Adelaide workshops. Both were very enjoyable to present, and thank you to all who attended. For more information on our upcoming workshops, or to register, please visit our website. We are looking forward to the remaining two workshops on the Brain and Anxiety. In total over 1000 clinicians and academics have attended the Brain and Anxiety workshops. The Remaining Brain and Anxiety Workshop dates are: 1 - 2 July – Perth 12 - 13 August - Launceston Neuroscience of Depression Workshop In September we commence our brand new workshop on Depression. The content of this workshop is quite different from the Brain and Anxiety workshop although there is about 10% overlap in Brain based information. The focus however, is on how these structures play a role in various forms of Depression. The rest of the workshop content focuses on neuroscientific models of understanding depression and various schemata that play a crucial role in depression— both in terms of the pathogenesis of depression and the treatment. Specific focus and discussion is dedicated to treatment application regarding these fundamental schemata: The Attachment Need The Need for Orientation and Control The need for Self-Esteem and Self-Esteem Enhancement The need for Pleasure Maximization The need for Consistency Regulation vs Trauma Specific emphasis is on treatment strategies for Depression in light of these schemata. Times: 9 - 10 September – Perth 23 - 24 Sep - Melbourne 30 Sep - 1 Oct – Adelaide 7 - 8 October - Brisbane 21 - 22 October – Canberra 4 - 5 November – Sydney For more information please see our website Page 8 Neuropsychotherapy News 5 July 2011 Regional Neuropsychotherapy Peer Discussion Groups We are progressing very well to activate our state wide regional peer discussion groups for clinicians interested in regular ongoing discussion regarding the applications of neuropsychotherapy in their therapeutic environments. We asked attendees at the Melbourne, Sydney, Canberra, Brisbane and Adelaide workshops if they would be interested in us facilitating local discussion groups and the reaction was very positive. As soon as the Perth Brain and Anxiety workshop is completed (early July) we will have a comprehensive list of clinicians interested to join these peer discussion groups in the various key locations in the country. A number of key clinicians indicate that the would be willing to facilitate these regional meetings. The lists will be forwarded to these key clinicians and they will do mail outs to those on the lists to arrange meeting times. We will also assist with publishing details in the Newsletters and hope to provide information regarding these meetings. This is a very exciting development for clinicians interested in Neuropsychotherapy and we trust this will add a lot of benefit to your therapeutic work. A additional plus of these groups would be that it also addresses the need for peer discussion/supervision in terms of Professional Development. There are no obligations to attending these groups but at least it will provide a unique opportunity to be part of this exciting new development in psychotherapy. If you are not sure if you signed up for a local discussion group—please drop us an e-mail at [email protected]. We will keep you posted. Contact us: If you have any further questions or comments about the newsletter or interest group, or to unsubscribe, please contact us at [email protected] You can also phone us on 07 3294 3220.
