Phosphatidylserine - June 3, 1995


Cognitive decline in the elderly: a double-blind, placebo-controlled
multicenter study on efficacy of phosphatidylserine administration

This double-blind study assesses the therapeutic efficacy and the safety
of oral treatment with phosphatidylserine (BC-PS) vs placebo (300 mg/day
for 6 months) in a group of geriatric patients with cognitive impairment.
A total of 494 elderly patients (age between 65 and 93 years), with moderate
to severe cognitive decline, according to the Mini Mental State Examination
and Global Deterioration Scale, were recruited in 23 Geriatric or General
Medicine Units in Northeastern Italy. Sixty-nine patients dropped out within
the 6-month trial period. Patients were examined just before starting therapy,
and 3 and 6 months thereafter. The efficacy of treatment compared to placebo
was measured on the basis of changes occurring in behavior and cognitive
performance using the Plutchik Geriatric Rating Scale and the Buschke Selective
Reminding Test. Statistically significant improvements in the
phosphatidylserine-treated
group compared to placebo were observed both in terms of behavioral and
cognitive parameters. In addition, clinical evaluation and laboratory tests
demonstrated that BC-PS was well tolerated. These results are clinically
important since the patients were representative of the geriatric population
commonly met in clinical practice.Cenacchi T, Bertoldin T, Farina C,

Effects of phosphatidylserine in Alzheimer's disease

We studied 51 patients meeting clinical criteria for probable Alzheimer's
disease (AD). Patients were treated for 12 weeks with a formulation of
bovine cortex phosphatidylserine (BC-PS, 100 mg t.i.d.) or placebo, and
those treated with the drug improved on several cognitive measures relative
to those administered placebo. Differences between treatment groups were
most apparent among patients with less severe cognitive impairment. Results
suggest that phosphatidylserine may be a promising candidate for study
in the early stages of AD.

Pharmacological treatment with phosphatidyl serine of 40 ambulatory
patients with senile dementia syndrome

Phosphatidyl serine was administered for 60 days to subjects suffering
from chronic cerebral decompensation, producing an improvement in mnesic
and neuropsychic symptomatology with positive effects even some time after
suspension of the drug.

Effects of phosphatidylserine in age-associated memory impairment

We treated 149 patients meeting criteria for age-associated memory impairment
(AAMI) for 12 weeks with a formulation of phosphatidylserine (100 mg BC-PS
tid) or placebo. Patients treated with the drug improved relative to those
treated with placebo on performance tests related to learning and memory
tasks of daily life. Analysis of clinical subgroups suggested that persons
within the sample who performed at a relatively low level prior to treatment
were most likely to respond to BC-PS. Within this subgroup, there was
improvement
on both computerized and standard neuropsychological performance tests,
and also on clinical global ratings of improvement. The results suggest
that the compound may be a promising candidate for treating memory loss
in later life.Crook TH, Tinklenberg J, Yesavage J, et al. Effects of
phosphatidylserine in age-associated memory impairment. Neurology 41:644-649;
1991.

Effects of phosphatidylserine therapy in geriatric patients with depressive
disorders

The effects of phosphatidylserine (BC-PS) on cognitive, affective and
behavioural symptoms were studied in a group of 10 elderly women with depressive
disorders. Patients were treated with placebo for 15 days, followed by
BC-PS (300 mg/day) for 30 days. The Hamilton Rating Scale for Depression,
Gottfries-Br.ANG.ane-Steen Rating Scale, NurseÕs Observation Scale
for Inpatient Evaluation and Buschke Selective Reminding Test were administered
before and after placebo and after BC-PS therapy, to monitor changes in
depression, memory and general behaviour. At the same time, basal plasma
levels of noradrenaline, MHPG, DOPAC, HVA and 5-HIAA, and
GH/beta-endorphin/beta-lipotropin
responses to clonidine stimulation were measured. BC-PS induced consistent
improvement of depressive symptoms, memory and behaviour. No changes in
amine metabolite levels or in hormonal responses to alpha 2-adrenoceptor
stimulation were observed.Maggioni M, Picotti GB, Bondiolotti GP, et
al. Effects of phosphatidylserine therapy in geriatric patients with depressive
disorders. Acta Psychiatr Scand (DENMARK) 81:265-270; 1990.

Preliminary evaluation of the effect of GABA and phosphatidylserine
in epileptic patients\

The effect of the combined administration of gamma-aminobutyric acid
(GABA) and phosphatidylserine was evaluated in a pilot study of 42 patients
with drug-resistant epilepsy. The group included patients with complex
partial seizures, simple partial seizures and absence seizures. Patients
with complex partial seizures and simple partial seizures showed no significant
improvement, on the other hand, there was a remarkable decrease in absence
seizures, linearly related to the dose of GABA and phosphatidylserine.
Side effects occurred in 9 patients and were usually mild.<I>Loeb C, Benassi
E, Bo GP, et al. Preliminary evaluation of the effect of GABA and
phosphatidylserine

Double-blind randomized controlled study of phosphatidylserine in senile
demented patients

A double-blind randomized controlled study was conducted in 42 hospitalized
demented patients to evaluate the therapeutical effect of phosphatidylserine
(BS-PS). Half of the patients received 3 X 100 mg of this product, and
the other half a placebo of the same appearance. After a wash-out period,
prescription lasted for six weeks. To evaluate the patients, two distinct
rating scales were used: the Crichton Scale and an original one (Peri Scale)
designed in our geriatric unit (see Appendix). A circle crossing test was
added. Out of the 35 patients who completed the trial, 18 had received
placebo and 17 BC-PS. The results indicated a trend toward improvement
in the BC-PS treated patients and an analysis of covariance showed a significant
(p less than 0.05) treatment effect on the Peri Scale. The results at the
end of the treatment period were compared with those obtained three weeks
later. Here again there was a statistically significant difference in the
Peri Scale results, indicating that modifications are drug-related. The
behavioral improvement shown in this study is in agreement with experimental
studies on aged animals.<I>Delwaide PJ, Gyselynck-Mambourg AM, Hurlet A,

Effects of phosphatidylserine on the neuroendocrine response to physical
stress in humans

The activity of brain cortex-derived phosphatidylserine (BC-PS) on the
neuroendocrine and neurovegetative responses to physical stress was tested
in 8 healthy men who underwent three experiments with a bicycle ergometer.
According to a double-blind design, before starting the exercise, each
subject received intravenously, within 10 min, 50 or 75 mg of BC-PS or
a volume-matched placebo diluted in 100 ml of saline. Blood samples were
collected before and after the exercise for plasma epinephrine (E),
norepinephrine
(NE), dopamine (DA), adrenocorticotropin (ACTH), cortisol, growth hormone
(GH), prolactin (PRL) and glucose determinations. Blood pressure and heart
rate were also recorded. Physical stress induced a clear-cut increase in
plasma E, NE, ACTH, cortisol, GH and PRL, whereas no significant change
was observed in plasma DA and glucose. Pretreatment with both 50 and 75
mg BC-PS significantly blunted the ACTH and cortisol responses to physical
stress.Monteleone P, Beinat L,Tanzillo C, et al. Effects of phosphatidylserine

Blunting by chronic phosphatidylserine administration of the stress-induced
activation of the hypothalamo-pituitary-adrenal axis in healthy men

The effect of chronic administration of phosphatidylserine derived from
brain cortex on the neuroendocrine responses to physical stress has been
examined in a placebo-controlled study in 9 healthy men. Phosphatidylserine
800 mg/d for 10 days significantly blunted the ACTH and cortisol responses
to physical exercise (P = 0.003 and P = 0.03, respectively), without affecting
the rise in plasma GH and PRL. Physical exercise significantly increased
the plasma lactate concentration both after placebo and phosphatidylserine.
The results suggest that chronic oral administration of phosphatidylserine
may counteract stress-induced activation of the hypothalamo-pituitary-adrenal
axis in man.<I>Monteleone P, Maj M, Beinat L, et al. Blunting by chronic

Double-blind study with phosphatidylserine (PS) in Parkinsonian patients
with senile dementia of Alzheimer&Otilde;s type

Experimental and clinical studies showed that Phosphatidylserine&Ntilde;special
preparation from cow&Otilde;s brain by FIDIA, Abano Terme, Italy&Ntilde;is
able to influence cerebral changes contributed to the symptoms of senile
dementia of Alzheimer&Otilde;s type. The application of the computerized
EEG method DYNAMIC BRAIN MAPPING (HZI Research Center, Tarrytown, New York)
is able to proof the therapeutic effect of Phosphatidylserine: the acceleration
of a slowed EEG in Parkinsonian patients with SDAT. These reactions were
seen previous to the favourable clinical influence documented by the Sandoz
Clinical Assessment Geriatric Scale (SCAG), which showed a significant
amelioration in anxiety, motivation and affectivity by the verum drug.
Acute and long-term CEEG results&Ntilde;till 18 months&Ntilde;showed that
the so-called Theta anteriorisation can be reduced or even abolished, this
is replaced by Alpha waves. Even in preclinical cerebral changes this method
open the possibility to show incipient alterations of the brain metabolism.
Preliminary therapeutic results leads to this and not proven hypothesis
that prevention or retardation of cerebral ageing might be possible.<I>Funfgeld

Double-blind cross-over study of phosphatidylserine vs. placebo in
patients with early dementia of the Alzheimer type

Thirty-three patients with mild primary degenerative dementia according
to DSM-III (MMS between 15 and 27) took part in a double-blind cross-over
study of phosphatidylserine (Fidia, 300 mg/d) versus placebo. Both treatment
phases lasted for 8 weeks with an 8 week washout phase in between and a
4 week washout phase before treatment phase one. Clinical global improvement
ratings showed significantly more patients improving under BC-PS than under
placebo during treatment phase one. The improvement carried over to the
following wash-out and treatment phases. There were no significant improvements
in GBS dementia rating scale, psychometric tests or P300-latency. 16-channel
EEG mapping findings indicated that the patients initially showed higher
power values in all frequency bands (except alpha), when compared to a
younger, healthy control group. BC-PS reduced the higher power values compared
to placebo, shifting EEG power more towards the normal level.<I>Engel RR,

Phosphatidylserine in elderly patients. An open trial

Thirty-five patients (19 males, 16 females) with prevalent involvement
of cognitive functions associated with behavioural changes, were treated
with phosphatidylserine (300 mg daily) for a period of two months. The
therapeutic activity of the drug was evaluated through neuropsychological
tests and behavioural rating scales. The results obtained encourage us
to suggest phosphatidylserine as a possible useful tool in the treatment
of mild and moderate deterioration of cognitive functions.Granata Q,
