 Dysregulation of WNT/WG signaling in neurological diseases and its potential relevance to NEDAMSS-associated brain pathology.

DiseaseRole of WNT/WG signalingKey referencesImplications for NEDAMSS
Alzheimer’s disease (AD)Promotes synaptic plasticity, neuronal survival, neurogenesis, and BBB integrity; suppresses amyloid-β and tau pathology. Dysregulation accelerates synaptic loss and neurodegeneration.[3942]Suggests that WNT impairment in NEDAMSS may drive synaptic dysfunction, neuronal vulnerability, and cognitive-motor decline.
Autism spectrum disorder (ASD)Abnormal WNT/β-catenin signaling disrupts neurodevelopmental programs, synaptic connectivity, and behavioral outcomes.[4347]Supports the role of WNT dysregulation in NEDAMSS-related developmental delay, atypical motor control, and cognitive phenotypes.
Parkinson’s disease (PD)Regulates dopaminergic neuron survival and synaptic function; restoration of WNT activity improves neuronal resilience.[48, 49]Provides a mechanistic basis for WNT-linked dopaminergic vulnerability in NEDAMSS, potentially explaining dystonia, tremor, and Parkinsonian features.
Neuropsychiatric disorders (NSD)WNT pathway dysregulation is associated with schizophrenia, bipolar disorder, and others, affecting cortical development and higher-order brain function.[5053]Suggests that WNT disruption may contribute to cognitive, affective, and behavioral disturbances reported in NEDAMSS.
