Within the central nervous system, synaptic plasticity, fundamental to processes like learning and memory, is largely driven by activity-dependent changes in strength. This plasticity often manifests as long-term potentiation (LTP) depression (LTD), which are bidirectional modulations of efficacy. Strong epidemiological experimental evidence show that heart-brain axis could be severely compromised both neurological cardiovascular disorders. Particularly, disorders, such heart failure, hypertension, obesity, diabetes insulin resistance, arrhythmias, may lead cognitive impairment, a condition known cardiogenic dementia. Herein, we review available knowledge on molecular mechanisms dementia arise describe how LTP and/or LTD induction maintenance CA1 region hippocampus metabolic syndrome, arrhythmias. We also discuss emerging endothelial dysfunction contribute directly altering hippocampal impairing synaptically induced activation nitric oxide synthase. A better understanding CV disorders impact proper function synapses will shed novel light underpinnings dementia, thereby providing new perspective for more specific pharmacological treatments.
