The substantial progress made in the basic sciences of brain has yet to be adequately translated successful clinical therapeutics treat central nervous system (CNS) diseases. Possible explanations include lack quantitative and validated biomarkers, subjective nature many endpoints, complex pharmacokinetic/pharmacodynamic relationships, but also possibility that highly selective drugs CNS do not reflect interactions different circuits. Although computational systems pharmacology modeling designed capture essential components biological been increasingly accepted pharmaceutical research development for oncology, inflammation, metabolic disorders, uptake field very modest.

Abstract Background Despite impressive dissemination programs of best-practice therapies, clinical psychology faces obstacles in developing more efficacious treatments for mental disorders. In contrast to other medical disciplines, psychotherapy has made only slow progress improving treatment outcomes. Improvements the classification disorders could enhance tailoring improve effectiveness. We introduce a multimodal dynamical network approach, address some challenges faced by research. These include absence comprehensive meta-theory, comorbidity, substantial diagnostic heterogeneity, violations ergodicity assumptions, and limited understanding causal processes. Methods Through application analysis, we describe how advance research addressing central problems field. By utilizing dynamic analysis techniques (e.g., Group Iterative Multiple Model Estimation, multivariate Granger causality), measurements (i.e., psychological, psychopathological, neurobiological data), intensive longitudinal data collection Ecological Momentary Assessment), inference methods GIMME), our approach comprehension Under umbrella systems e.g., graph theory control theory, aim integrate from longitudinal, measurements. Results The enables as networks interconnected symptoms. It dismantles artificial boundaries, facilitating transdiagnostic view psychopathology. integration enhances ability identify influential nodes, prioritize interventions, predict impact therapeutic strategies. Conclusion proposed psychological providing individualized models psychopathology suggesting individual angles.

Cognitive reserve (CR) is a protective mechanism that supports sustained cognitive function following damage to the physical brain associated with age, injury, or disease. The goal of research was identify relationships between CR, and connectivity. A sample 90 cognitively normal adults, ages 45-64 years, had their resting-state activity recorded electroencephalography (EEG) completed series memory executive assessments. CR estimated using years education verbal IQ scores. Participants were divided into younger older age groups low- high-CR groups. We observed greater left- than right-hemisphere coherence in participants, right- left-hemisphere participants. In addition, under eyes-closed eyes-open recording conditions for both low-CR more substantial difference individuals high regardless age. Finally, participants low exhibited mean whereas opposite pattern CR. Together, these findings suggest possibility shift relationship connectivity during aging.
