S. Schreiber et al., An open trial of plant-source derived phosphatydilserine for treatment of age-related cognitive decline, ISR J PSYCH, 37(4), 2000, pp. 302-307
We assessed whether the efficacy of plant-source derived phosphatydilserine
tone of the phospholipids which play an important functional role in membr
ane-related processes in the brain) for treatment of age related cognitive
decline is consistent with previous (placebo controlled) positive findings
with bovine derivative of PS (BC-PS). Eighteen healthy elderly volunteers m
eeting Age Associated Memory Impairment inclusion and exclusion criteria we
re treated for 12 weeks with plant-source derived phosphatydilserine (PS) (
100 mg x 3/day P.O.) and evaluated at base line, after 6 weeks of treatment
and at the end of the trial. Fifteen concluded the study. All but two outc
ome measures elicited a significant drug over time effect. Post-hoc paired
t-tests showed that the significant effect was attributable to an improveme
nt from base line to week 6 and that effect was maintained at week 12. Thes
e results are encouraging. However, they await double-blind controlled veri
fication in a large sample before suggesting that this may be a viable appr
oach to the treatment of age-related cognitive decline, without exposing th
e patients to possible hazards involved in the treatment with bovine deriva
tive of PS (BC-PS).
