CDP-choline (cytidine diphosphate choline) is effective for the treatment of intracranial organic lesions, such as head injury, Parkinsonism, cere-brovascular disease, etc., CDP-choline can be admini-strated via intrathecal route as well as intravenous or intramuscular one.

The availability of intrathecal CDP-choline was tested on 26 paralized, artificially respirated cats, by observing the recovery of disturbed EEG, which was produced by pressure by mean of ballooning on the midbrain for ten minutes enough to flatten the EEG (Fig. 1). The EEG grade that was used in this experiment was shown in Figure 2.

The EEG of control group recovered very slowly and insufficiently as shown in Figure 3, whereas the EEG of cats with intrathecally administrated CDP-choline exhibited remarkable and sufficient improvement as well as those with intravenous administration (Figs. 4 and 5). The former re-covery was faster than the latter one. The effective-ness of CDP-choline was enhanced to maximum by combinated administration of intrathecal and in-travenous CDP-choline as shown in Figures 6 and 7, the mechanism of which was diagramatized in Figure 8.
