Alzheimer’s dementia is the countermodel of plasticity, an irreparable disconnection

Evidence

Both cases involve a disconnection from the rest of the network. In one case, reconnection is possible; in the other, it is not. This is how dementia appears as the countermodel of plasticity: the irreparable loss of connections at the core of the cerebral network entails a definitive disconnection from the social network. — Catherine Malabou, What Should We Do with Our Brain?, 20
