The effect of l-acetyl carnitine (l-AC) on cerebral blood flow (CBF) was evaluated in 20 patients with chronic cerebrovascular disease, who suffered an ischaemic stroke at least 6 months before the study. All patients performed a CT scan and were investigated with xenon-133 by brain dedicated single photon emission computed tomography (SPECT, Tomomatic 32, Medimatic Inc., Copenhagen). A single high dose (1.5 g) of l-acetyl carnitine was intravenously administered to 10 patients, while sodium acetate as placebo was injected to 10 other subjects. Cerebral blood flow (ml/min × 100 g) was evaluated before and 45 min after the injection. No changes were observed after placebo injection (43 ± 12 ml/min × 100 g versus 43 ± 10 ml/min × 100 g). CBF increased (from 42 ± 9 ml/min × 100 g to 46 ± 9, P
