Neuropsychiatric disorders including mood, psychotic, anxiety, eating disorders, and neurological conditions like stroke and neurodegeneration
Key Mechanisms
Dysfunctional neuronal message passing, aberrant belief updating, impaired precision weighting in synaptic function, and dysconnection in brain networks
Target Population
Patients with psychiatric disorders characterized by synaptopathies and neurological disorders involving brain disconnection
Care Setting
Neuropsychiatric and neurological clinical settings focusing on diagnosis and management of brain connectivity disorders
Key Highlights
Active Inference (AI) framework explains neuronal processing as Bayesian model evidence maximization or variational free energy minimization.
Synaptopathies impair neuromodulatory precision weighting, causing rigid or overly sensitive inferences leading to psychiatric symptoms.
Distinction between synaptopathies (functional dysconnections) and brain disconnection syndromes (structural damage) is critical for advancing neuropsychiatric models.
Guideline-Based Recommendations
Diagnosis
Consider computational models of inference and precision weighting to understand symptomatology in psychiatric disorders.
Distinguish between synaptopathies and structural disconnection syndromes based on functional integration and neuromodulatory dysfunction.
Management
Target neuromodulatory systems (dopamine, noradrenaline, acetylcholine, serotonin) to modulate precision weighting and improve inference.
Incorporate computational frameworks like Active Inference to guide therapeutic strategies addressing dysfunctional belief updating.
Monitoring & Follow-up
Assess changes in functional connectivity and synaptic precision weighting through neuroimaging and neurophysiological measures.
Monitor symptom evolution in relation to inferred changes in neuronal message passing and network integration.
Risks
Failure to correctly calibrate precision weighting may exacerbate symptoms such as hallucinations and delusions.
Ignoring the distinction between synaptopathies and brain disconnection may lead to suboptimal treatment approaches.
Patient & Prescribing Data
Individuals with psychiatric synaptopathies and neurological disconnection syndromes
Pharmacological modulation of neuromodulators involved in precision weighting can influence symptom severity and cognitive inference processes.
Clinical Best Practices
Utilize computational neuropsychiatry frameworks to interpret complex symptom presentations.
Integrate neurobiological and computational data to differentiate synaptopathies from structural brain disorders.
Apply precision medicine approaches targeting neuromodulatory systems to restore functional connectivity and improve outcomes.
A new BMJ Opinion piece takes aim at a growing tendency among clinicians: translating public behavior into clinical diagnosis—especially when the subject is a political leader.
