We know that with age, the connections between neurons -- the way neurons talk to each other, the synapses -- they start to deteriorate; neurons die, the brain starts to shrink, and there's an increased susceptibility for these neurodegenerative diseases.
Sabemos que, com a idade, as ligações entre neurónios, a forma como comunicam, as sinapses, começam a deteriorar-se, os neurónios morrem e o cérebro começa a encolher, aumentando a suscetibilidade de doenças neurodegenerativas.
