Definitions
- the invention relates to the use of a composition for improving memory function, in a subject with a mini-mental state examination of 24-26.
- Memory impairment is a serious shortcoming in many humans, particularly those suffering from Alzheimer's disease and/or elderly. Such impairments often have serious consequences, such as reduced quality of life, difficulties in performing the activities of daily living, potentially resulting in hospitalization or institutionalization.
- Nutritional therapy is particularly desired in subjects who have relatively mild symptoms of memory impairment, i.e. subjects with a mini-mental state examination score (MMSE) of 24 to 26.
- MMSE mini-mental state examination score
- the present inventors have recognized that in this particular subgroup memory improvement has enormous effect for the subject activities of daily living and quality of life.
- This subgroup of subjects is distinct in that the pathological pathways have just started to develop.
- any score of 27 or higher is effectively normal.
- 20-26 indicates mild dementia, 10-19 moderate dementia, and below 10 severe dementia. It was the present inventors' belief that within the group of 20-26, the memory impairment in the sub-group of 24-26 may even be reversible, as the pathological pathways have just started to develop.
- the subgroup of subjects with a MMSE score of 24 to 26 comprises two populations. Firstly, it comprises those subjects who do not receive medication for memory impairment, i.e. the drug na ⁇ ve subjects.
- the treatment of this subgroup is particularly preferred as in these subjects the balance between side effects and benefits of pharmaceutical intervention is still negative. Providing nutritional therapy to these subjects is desired because of the relative lack of negative side effects.
- the subgroup of subjects with a MMSE score of 24 to 26 comprises a population of subjects with a very mild form of Alzheimer's Disease. Memory improvement through nutritional therapy is particularly desired in subjects with a very mild form of Alzheimer's Disease. If improvement of memory function could be achieved pharmaceutical intervention could be reduced or even postponed if significant improvements are observed.
- the present inventors surprisingly found, through clinical study, that administration of a composition containing (a) uridine or uridine phosphate; and (b) docosahexaenoic acid and/or eicosapentaenoic acid showed a significant improvement of memory function in subjects with a MMSE of 24 to 26. Compliance and tolerability were very high and side effects were relatively low. It was particularly surprising that the present clinical data showed an actual improvement in memory function, more than just a reduction in the rate of decline in memory function. Additionally it was found that in this subgroup the delayed recall function was significantly improved. The results of the clinical study are summarized in the examples.
- composition comprising:
- the present invention relates to subjects with a mini-mental state examination of 24, 25 or 26, i.e. of 24-26.
- the mini-mental state examination is a brief 30-point questionnaire test that is used to assess cognition. In the time span of about 10 minutes it samples various functions including memory and orientation.
- the MMSE test includes simple questions and problems in a number of areas: the time and place of the test, repeating lists of words, language use and comprehension, and basic motor skills. Any score of 27 or higher (out of 30) is effectively normal; 20-26 indicates mild dementia; 10-19 moderate dementia, and below 10 severe dementia.
- the MMSE is a standardized test.
- the subjects as treated in the present invention have a mini-mental state examination score of 24-26 and are preferably drug na ⁇ ve and/or suffer from a very mild form of Alzheimer's disease, preferably drug na ⁇ ve subjects with a very mild Alzheimer's disease and a MMSE of 24-26.
- drug na ⁇ ve refers to subjects who do not ingest one or more of cholinesterase inhibitors, N-methyl-D-aspartate (NMDA) antagonists and ginkgo biloba. In the clinical study presented here, it was found that the present composition is effective in drug na ⁇ ve subjects.
- the subject is preferably a human, preferably an elderly human, preferably at least 50 years of age.
- the present invention relates to use of the present composition for (i) the improvement of memory and/or (ii) treatment and/or prevention of impaired memory function.
- the present invention provides a method for (i) the improvement of memory and/or (ii) treatment and/or prevention of impaired memory function in a subject in need thereof, said method comprising the administration of the present composition to said subject.
- the present invention relates to the treatment of an impaired memory function. It was found that the memory function actually improved when the present composition was administered to the subject.
- the memory function of a human subject can suitably be determined using the (modified) ADAS-cog, Wechsler Memory Scale, WMS revised.
- Delayed recall function can be measured by a prose recall task 30-minute delay interval. Delayed recall of a prose passage is not a measure to differentiate clearly between very mild dementia of the Alzheimer type and normal ageing.
- the present composition can also advantageously help subjects not (yet) suffering from Alzheimer's disease in improving the delayed recall function.
- the invention provides a method for improving delayed recall and/or the treatment and/or prevention of an impaired delayed recall function.
- the present composition comprises uridine and/or uridine phosphate.
- the present composition comprises one or more uridine phosphates selected from uridine monophosphate (UMP), uridine diphosphate (UDP) and uridine triphosphate (UTP).
- UMP uridine monophosphate
