TREATED OR NOT WITH DRUGS

 Summary.

School  learning in 8 years old children of two group (Experimental  Group:  40 Ss,  23  F and 17 M; 36 pure trisomy 21, 3 translocations and  1  mosaicism;  at least 5 years of individualised drug therapy. Control Group: 24 Ss, 13 F and  11 M; 21 pure trisomy 21, 2 translocations and 1 mosaicism; no drug treatment)  was compared.   Classroom  behaviour, reading (syllables,  plain  words,  sentences), writing  (copy,  dictation, invention from a visual model, free  invention)  and arithmetic  (digit  sequence, addiction and subtraction up to 20 were  evaluated according to a 5 point scale.

Drug  treated  Ss presented significant improvements in  all  the  investigated fields  but  classroom behaviour showed only a very strong trend  (.053)  towards amelioration.

Since  both  groups  differ  from the general  population  as  for  gender  and chromosomal  anomalies distribution, the generalisation of these very  promising results warrants some caution.

Since  1979 I have been occupied with the use of the drug therapy in  Downs Syndrome.  Among the various areas this therapy has demonstrated to have  effect there  are a definite improvement in attention, concentration, long-term  memory and  speech. This means an improvement in the pre-requisites  indispensable  for school learning.
Owing the difficulty to make an investigation in this field,  a valuation of the capacity of school learning has never been done before.  In  this  study, from 502 cases personally visited and  checked  (seen  between January  1979  and  September 1992) a survey was carried out  to  compare  school learning in 8 years Down children coming for a first visit at that age  (control group)  with school learning of same age children treated with drugs for at  least  5 years (experimental group).

 

Materials and methods

The records pertaining to an unselected consecutive series of 502 Down’s children visited between January 1979 and the end of September 1992 were re-examined, and those  who had had a diagnosis of childhood psychosis were first excluded. 

From the remaining  were extracted the records of those who came for their first visit  between  the ages of 7 years 7 months and 8 years 6 months and  also  the records of the children who had a check at the same age period, after undergoing an individualised drug treatment for at least 5 years. 

Data  were gathered from all of these regarding sex, chromosomal diagnosis  and the age (year and months) at the first visit  (Control Group) or at check  visit in the same age period (Experimental Group).

Also  data  were gathered regarding classroom behaviour and  reading  (isolated syllables, plain words, sentences) writing (copying, dictation, invention on sight models,  real  or picture or photo, free invention)  and  elementary  arithmetic (sequence  of numbers more than 20, addition and subtraction up to at least  20, with 1 or 2 digits).

These  data  were reported by parents and often controlled  in  exercise  books shown during the visit of control or by school reports at the end of the year. 

All  of these fields were investigated and evaluated by using a 5 points  scale  from 0 (negative behaviour or zero learning) to 4 (behaviour and learning normal). 

The  statistic  comparison between the 2 groups was done by the test  of  Mann-Whitney.

Results

It  was  possible  to collect the charts of two groups  of  Down  subjects,  an Experimental  Group  (EDG) with 40 children and a Control Group  (CDG)  with  24 children.

Comparing the results of the two groups, according to the field investigated, the results  obtained  from the experimental group reached a  significant  statistic level, sometimes a very high level, in all the learning fields of this study. 
Although  the  experimental  group obtained higher rates,  the  difference  in classroom  behaviour  has only a high tendency to a  major  suitability,  without attaining for a while the minimum conventional significant level.

Discussion.

 With  view  to the 2 groups, I have to say that the ratio M/F is  reversed,  as compared  to  the general population of Down subjects where boys are  about  one third  more than girls. The distribution of chromosomal anomalies, although  not very  different from the Italian and international rates, cannot be  assumed  as representative,  especially as for CDG, because the exiguity of the  samples has probably not expressed true rates for mosaicisms or translocations. 

 Though  important as for the generalisation of the results,  these  differences have  less  importance as for our research, the aim of which was,  for  now,  to discover, if any, an improvement in school learning between the 2 casual groups, one  of them  treated  by drug for a long period. The two samples are  very  similar  in their  distribution  of the sexes, of the chromosomal anomalies and the  age  in which they were taken.

 The result of the drug therapy on school learning at the age of 8 was certainly different in the two groups, being definitely better in the experimental  group, in which the components had at least 5 years drug treatment.  Regarding the actual treatment, the therapy is individualised, that means  that it could be different from child to child.

 The therapies were not reported  here case  by  case, but the rationale and a large idea of it could be  deduced  from other  papers  (Cocchi, 1987a; Cocchi, 1987b; Cocchi, 1988;  Lamma  and  Cocchi, 1988;  Cocchi,  1989; Cocchi, 1990; Cocchi, 1991; Cocchi, 1992). 

 The  classroom behaviour is much more adequate in the experimental group,  where in  the  control  group  there are more hyperkinetic children,  with  a  marked attention deficit.

 With  regards to school learning it is evident that drug therapy is not  able  to resolve  every situation of poor learning, but in the group of children  treated there  was only one case of zero learning, and those with little  learning  were definitely few.

The  sequence by which the various abilities were drawn up presents  decreasing scores attained by each child of both groups.

The  best results were in reading syllables, in copy writing and in  memorising number  sequences. Being that learning occurs first also in normal children,  it is  probable  that the process of promotion or stimulation in  the  capacity  of learning  becomes developed in the same way, a fact that in Down  children,  was  already noted in England by Buckley et al., in 1986. 

 It  is not possible for me to make a comparison with other research as  I  have not  found  anything  similar in literature, either  in  treatment  or  standard valuation in school learning. I retain that an tailored drug therapy  that tends  to  favour learning should be valued in long term and  based  on  precise indicators, clear and comprehensible.

The  presentation  of  this research during a  refreshment  course  for  school  teachers  (San  Costanzo,  September  1992) confirmed that  the  choice  of  the parameters  investigated  in this study was the same the school teachers  use  in evaluating learning.

Conclusions.

The comparative examination of the results of a drug therapy individualised for school learning for a group of Downs aged 8 (elementary level 2-3) with a  group of Downs subjects aged 8 and not treated (same school level) has shown that  the group   treated  with drugs for at least 5 years have attained   average  higher scores. In 10 out of 11 investigated fields significant differences were reached. 

 The  results again confirmed the intuition that a  therapy  prevalently  anti-stress  in Down’s Syndrome (Cocchi, 1987a) is a wide spectrum therapy which  can gain improvements also in intellectual performances.

 Nevertheless different characteristics between the two samples and the  general population  of Downs subjects, with regard to gender and  chromosomal  anomalies distribution  suggest  that  caution  must be taken as  for  the  generalisation  of these results.
