1 The science behind Nalysis (NeuroAnalysis )

2 Psychiatric diagnosis DESCRIPTIVE Composed from: Symptoms (complaints) signs (observations) Example: Depression Medical diagnosis ETIOLOGICAL The cause of the disease Place, body location Diseased process, pathology Example: Appendicitis In Medicine diagnosis is Etiological, the name of disease is composed of location and pathology, in psychiatry diagnosis is descriptive composed of symptoms, this is because the causes of psychiatric disorders are unknown.

3 Not knowing the causes of mental disorders impedes their cure To effectively treat mental disorders we should first reformulate them as brain disorders and validate (discover) their brain-related origins First step is to TRANSLATE phenomenology into brain disturbances P h e n o m e n o l o g y Brain T R A N S L A T E

4 P h e n o m e n o l o g y Brain The RDoC (Research Domain Criteria) is an Attempt by the previous INMH director Tom Insel to TRANSLATE psychiatric phenomenology into brain- related disturbances Translate

5 P h e n o m e n o l o g y Brain Network Disturbances The CBP (Clinical Brain Profiling) hypothesis proposes to concentrate on the “Circuit” level of brain organization and translate phenomenology into related-brain network disturbances

6 Signs Symptoms History P h e n o m e n o l o g y CBP proposes that phenomenology of psychiatric disorders can be translated / defined by a vector of 6 entries Connectivity segregation Connectivity Integration Plasticity Optimization Plasticity De-optimization Constraint Frustration Disturbed Resting-state default mode network Frustration Translate

9 Signs Symptoms History P h e n o m e n o l o g y To Validate CBP Sensors and wearables are required. Sensors collect the phenomenology and Brain-imaging EEG wearable synchronously monitors phenomenology-related brain disturbances Translate phenomenology

10 Signs Symptoms History P h e n o m e n o l o g y Validation will require finding causal relationships between phenomenology and brain disturbances this will require machine learning and theory driven efforts (theory being the CBP hypothesis) CBP Theory Driven phenomenology Deep Learning
