Synaptic impairment as primary pathomechanism

Synaptic impairment as primary pathomechanism enters the Adult Cognitive Disease corpus through the work of Jukka Welling (submission 37), and is indexed here as one of the concepts that submission puts to work.

The argument it belongs to

Jukka Welling's submission is summarised in this corpus as:

Alzheimer's disease results from the gradual accumulation of dysfunctional neural circuits and cognitive schemas that increasingly interfere with adaptive brain function. The dynamic nature of neuronal circuits, shaped by environmental influences and developmental factors throughout life, means AD begins with early tau deposits in the transentorhinal cortex -- an evolutionarily young and therefore structurally vulnerable brain region. The disease process reflects a failure of neural circuit plasticity and maintenance rather than a single molecular cause.

Where it sits

The submission scores against the framework's convergence nodes as: compensatory paradigm 4 · cytoskeletal collapse 2 · neuroimmune interface 2 · endosomal nexus 1 · transcriptional / epigenetic 1.

Its declared subject matter: neural circuits, synaptic plasticity, transentorhinal cortex, default mode network, evolutionary vulnerability, cognitive schemas, circuit dysfunction.

Named by the same submission

3 other concepts enter the corpus through the same paper, so they cover adjacent ground: Brain plasticity decline driving AD progression · Dynamic neural circuit failure model · Evolutionary vulnerability of brain structures.

Assembled from the corpus rather than written: the summary is quoted from the submission that named it; the node scores are read from its dossier. It has not yet been expanded into an article.
