To cure mental disorders the Psychiatrist of the future will need to discover the causes of mental disorders Abraham Peled © All rights resaved Oct 2015
1) Reformulate mental disorders as brain - disorders 2) Validate the brain disorders 3) Develop cure intervention / device Abraham Peled © All rights resaved Oct 2015
Psychiatric diagnosis is descriptive it is based on signs ( the patient looks sad ) and symptoms ( the patient complains of depression ) Abraham Peled © All rights resaved Oct 2015
I feel depresse d I look depresse d Abraham Peled © All rights resaved Oct 2015
While most clinicians agree that mental disorders are brain disorders, psychiatric diagnosis is not Brain - related Abraham Peled © All rights resaved Oct 2015
The term “ brain ” is not included in psychiatric taxonomy Brainitis Brainosis Connectomics Connectopathies Abraham Peled © All rights resaved Oct 2015
Without knowing exactly what is wrong with the brains of our patients we will never be able to cure ( fix ) them Abraham Peled © All rights resaved Oct 2015
In recent years we have learned a lot about the brain Abraham Peled © All rights resaved Oct 2015
For example we know that the brain is organized as a network Abraham Peled © All rights resaved Oct 2015
We also know that the brain is organized as a Small World network with Clusters and Hubs Clusters Hubs Abraham Peled © All rights resaved Oct 2015
We know that Small World brain organization is optimal for modal - specific specialization and multimodal integration Unimodal Transmodal multimodal Abraham Peled © All rights resaved Oct 2015
We also know that Small World brain organization supports Hierarchy with higher - level processing High - Level Low - Level H i e r a r c h yH i e r a r c h y Abraham Peled © All rights resaved Oct 2015
We know that such Small World brain organization is optimal for coherent integrated conscious experience Visual Auditory Conscious integration Abraham Peled © All rights resaved Oct 2015
The brain is Plastic. Neurons continually create ( Synaptogenesis ) and lose ( Atrophy ) connections Synaptogenesis Atrophy Abraham Peled © All rights resaved Oct 2015
The Plastic Brain interacts with the Environment Environment Action sensation Abraham Peled © All rights resaved Oct 2015
The Plastic Brain learns ( Hebb ) from the environment, memories Environment Action sensation memories Abraham Peled © All rights resaved Oct 2015
The Plastic Brain uses memories to create an Internal - Representation of the environment an internal model of the world Environment Action sensation Internal Representations model Abraham Peled © All rights resaved Oct 2015
When ‘ Adaptive ’ the internal model matches the environment, difference ( free energy ) between environment and internal representation is reduced Environment Action sensation Internal Representations model Adapt Match Free Ener gy Redu ced Abraham Peled © All rights resaved Oct 2015
Once created the internal model determines how we view the world and react to it, Experience - Dependent - Plasticity updates continually our internal model of the world Abraham Peled © All rights resaved Oct 2015
Experience - Dependent - Plasticity updates continually our internal model of the world The internal model determines how we view the psychosocial world and react to it, this is our personality style Abraham Peled © All rights resaved Oct 2015
Each of the organizational dynamics described so far can be disturbed in the brain of our patients Abraham Peled © All rights resaved Oct 2015
Network Organization Can be disturbed Abraham Peled © All rights resaved Oct 2015
Plasticity and Adaptability Can be disturbed Abraham Peled © All rights resaved Oct 2015
Internal Representations Can be disturbed Abraham Peled © All rights resaved Oct 2015
Multiple disturbances typically occur together to various extents Network organization Plasticity and Adaptability Internal Representations Can be disturbed Abraham Peled © All rights resaved Oct 2015
Each type of disturbance generates ( causes ) a different set of phenomenology ( suffering ) Network organization Plasticity and Adaptability Internal Representations Can be disturbed Abraham Peled © All rights resaved Oct 2015
Network organization Disturbed consciousn ess Psychosis and schizophre nia Disturbanc e to network organizati on generates disturbed consciousn ess Psychosis and schizophre nia Abraham Peled © All rights resaved Oct 2015
Plasticity and Adaptability Mood and Anxiety disorders Disturb ances to plastic ity and adaptab ility causes Mood and Anxiety disorde rs Abraham Peled © All rights resaved Oct 2015
Internal Representations Personal ity Disorder s Disturbanc es to the Internal - Representa tions cause the different Personalit y Disorders Abraham Peled © All rights resaved Oct 2015

To Validate Clinical Brain Profiling ( CBP ) a battery of various signal – processing methods should be put in place Pixels, Sensors Correlation analysis ( non - linear ) Graph analysis ( small - world ) SPM, DCM Entropy measures Abraham Peled © All rights resaved Oct 2015
Brain organization can be monitored continually using EEG wireless wearables Pixels, Sensors Correlation analysis ( non - linear ) Graph analysis ( small - world ) SPM, DCM Entropy measures Abraham Peled © All rights resaved Oct 2015
The Mental Status Examination can be evaluated (“ sensed ” ) using wearable, and monitoring of Cyber - activity Behavior Speech Face expressio ns Thought Cognition Abraham Peled © All rights resaved Oct 2015
Sensing Mental Status Examination can be synchronized with EEG monitoring Behavior Speech Face expressio ns Thought Cognition Abraham Peled © All rights resaved Oct 2015
Coupling ongoing phenomenolog y changes synchronized with ongoing monitoring of brain organization will generate large data that will point to the correlations between mental disorders and brain disturbance – Machine - Learning will probably work here Abraham Peled © All rights resaved Oct 2015
It is predicted that Machine - learning alone cannot complete the discovery process and that a theory - driven approach similar to CBP will be required Pixels, Sensors Prediction Evidence CBP Compare VALIDATE Abraham Peled © All rights resaved Oct 2015
Any therapeutic intervention to eliminate CBP disturbances will need a feed - back Loop mechanism one that continually guides and estimates corrections, “ Brain - Pacing mechanism ” Monitor CBP disturbance Correct CBP disturbance Monitored guided correction Correction Estimation Abraham Peled © All rights resaved Oct 2015
Such operation will probably require a Head Mounted Platform a hat for the therapy period / sessi on. A platform to support the sensory - guided interventio n. An interventio n engine relevant to activate remote non - invasive mediation to correct CBP disturbance s Monitor CBP disturbance Correct CBP disturbance Monitored guided correction Correction Estimation Camera Microphone Wireless transmitter Motion sensing Dry EEG electrodes Intervention Engine Abraham Peled © All rights resaved Oct 2015
Eventually the entire Head Mounted Platform and it ’ s operation, will have to be shrunk to the size of a Sticker and the brain intervention miniaturized to injectable ( or sniffed ) neuronal - related nanoparticles ( the CBP algorithm remains )
Abraham Peled © All rights resaved Oct 2015 The intervention at the brain level will need to be both neurological and CBP - relevant, for example here is a predicted intervention to the interneurons of layer 5 of the Prefrontal cortex for its Hub network - controlling effect for whole – brain organization
