1. Enhancement of episodic memory and reduction of intrusion errors are considered as the most characteristic outcome of cholinergic drugs administration in AD patients. 2. Since the nootropic drugs Piracetam and Oxiracetam are deemed to act through a cholinergic mechanism, we checked whether AD patients treated with these drugs would show the same pattern of neuropsychological improvement. 3. Results were negative, since (a) episodic memory showed a similar degree of improvement both in patients treated with these drugs and in patients treated with placebo; (b) the number of intrusions tended to increase, rather than to decrease, after the treatment period.
