There is evidence for a decrease in markers of cholinergic neuron activity and for changes in brain glutamate, dopamine, norepinephrine, serotonin, and somatostatin. Eventually, cholinergic neurons die or are destroyed. Treatment has focused on increasing the amount of acetylcholine in the synapse by inhibiting the breakdown of acetylcholine.
