This text [Cocchi, 1985], whose importance in child neuropsychiatry goes always to become greater,  will reflect in  a particular way, the views and the therapeutic experience of the author. So, it is going far, in part, from ideas and classification commonly approved.  

Years of practice and a wider angle of  therapeutic results in not predictable  fields, as for the current opinions about,  do think that this is a practicable road. This is  not only from a clinical point of view, but perfectly in accord with the new neurophysiological basic research. It can drive to a more suitable comprehension and  therapy.  

The idea of depression - in childhood,  because  what concerns our interests, but the same would  pertain even to the adults' depression - does not  will  regarded, as usually happens, as the mood fall symptom.  This last instead it is only one of its symptoms, and not always present among others, but in the inhibition sense.  That is the depression, in dynamic sense,  of some neurochemical brain mechanisms. 

 

Such inhibition ( or reduced functioning) will be considered at the origin of peculiar symptoms  that  I will point out as defective symptoms, due  to a deficit of functionality. We will however find other symptoms, as happens frequently, close to defective symptoms. These other symptoms reflect the compensation action following to a hyper-function of other neurochemical mechanisms. 

I shall term those as symptoms of compensation.  In this way the horizon of the depressive illness widens and we may understand not only the manifest depressions (reactive, vital or mixed) more typical of the adult person, but not unknown in childhood. 

 Moreover  we can diagnose the so-called masked depressions, the psychosomatic somatizations and all those illnesses  that benefit from a suitable antidepressant and anxiolytic  therapy.  Finally  we may well frame those not always  individualized as depressive because they often miss the  mood fall symptom. So sometimes even because its presence is pale to the point that it seems more secondary to the somatic aspects of an illness of which the depressive origin is not perceived.

 Following these premises, the depressive illness is always a neuropsychological disorder (and in the child this is much more evident that in the adult ). So, because the neural level involved is that, more fine, of the synapse, than  that, more coarse, of the neuron.  

To that it has to add that the depressive illness is always a morbid condition that implicates the whole body, in its neurovegetative, motor and intellectual components, besides the affective one. This last, is responsible, to a large extent, of the consequent impairment of psychological and social relationships, if they were not already  the cause of the illness itself.  

Since over, it  is evident the reference that we need  to do to the notion of homeostasis. We mean it  as a strong trend of the body to the best balance, where all vital functions, and neuropsychological ones work the better  they can do. A such balance is the fruit of the selective adaptations made during millions of years in  living organisms from the more simple, as first appeared, till the human species.   

It has to add that a refined, adaptable organism, as it is the human one and its more complex organ, the brain, although having reached high specialization  levels, does not be led to totally outfit so easily. To face it,  there are many adjusting mechanisms of reserve (compensatory mechanisms ) that can minimize the followings of partial bad functioning.  

Of course, as many as compensations may be put into action,  then there are a limited number of them. So, it can happen that they not succeed to face a damage that goes beyond the limits of tolerance of a certain  brain area that presides to a peculiar function. So the brain can abandon that area and that function, even if not entirely, because in this last case it would come out atrophy.   

We can now understand how, when it is not precise brain damage, the first to be disarmed those areas which control the lastly acquired abilities (in order: Logical-formal thought, fine motility, language) which are typical of the  adult human being. The more primitive, presiding to the neuro-vegetative life, will be more defended. Between these two extremes are possible all  intermediate conditions, and the process of brain senescence notice it in an exact way. The same will happen, but reversely, when the damages occur in a developmental evolutionary moment.  

According to the extent of the damage, and to the moment where the brain suffered from the injury, the child will get those neuropsychological abilities compatible with the precarious balance that came out.  Of course he will not have instead the more specialised abilities (see what happens in the mental deficiency).   We have to add still supposition, which however it serves to interpret precise clinical facts. It stands to the reason that brain damage, even when the injurious agent has diffused action, as it happens for example in the encephalitis, does not injure in a uniform way all the structures and functions of the brain.  

That is probably creditable to the fact that exists a differential vulnerability of the different brain areas, for which what preside more primitive functions result even more protected. See, to this intention, what happens in some deep forms of a coma, where nearly noticeable cerebral electric activity misses (At EEG check ) but where neurovegetative functions as respiration, digestion, blood circulation, urine issue, thermoregulation etc., can instead  be preserved.   

 It will be then easy to understand, from what I  said, how even in situations of exact brain damage, with one specific lesion, won't be only the function mainly and heavily involved being  led out of use, but by to it, other functions can be impaired, and become less valid. This impairment will be of depressive type, as  the sense we gave to this word:  inhibition of peculiar neurochemical circuits, with or without compensation  due to the hyperfunction of others.  

It exists finally an other aspect that starts to be often appraised. The brain damage corresponds to the destruction of the struck brain area ( for which the impairment of the function has its correspondent in the anatomical lesion)? Or are there any damages where, even without any destruction, a functional blockade came out, where its operative level is only sufficient to prevent the atrophy ( ex non uso), but not enough to allow  the function operates?  According to whether the response is, the brain plasticity, which is the ability to mend the lesion, is only of vicarious type?

That means that the injured part can be replaced from a close area that assumes its tasks and functions. Or it may even  be of reactivation type (the injured part, not working, but not destroyed,  may find reactivation if adequate neurochemical conditions can be reformed )? As for my experience, it seems I can give a positive answer even to the hypothesis of a reactivation [by growing of new synapses].

However, it will be as more efficient as smaller is the age of the subject, and when first the therapeutic treatments become set out.  Base on these premises, it has to result clear that I think depressive phenomena can exist also as alone. Nevertheless,  they can even  be accompanying symptoms of  many other illnesses with lesional damages, as it happens in the mental insufficiency, the cerebral palsies in children, the epilepsy, the syndrome of Down, etc.  

I did not absolutely say that it does never work a secondary depression, the result of  a loss of self-esteem creditable to the awareness of own infirmity, and its consequent  social disability, (that however may always be  there!). A primary depression would also have its room, in the sense here described.   This yet doesn't want to say that there are not morbid situations as only depressive.

On the contrary  this is  the more frequent case in the practice of the child neuropsychiatry. In these  depressions where the root was damage, it  kept as limited to a functionality fall. The symptomatic expression of which shows defective symptoms. When instead the entry in operation of compensation mechanisms appears, we can then understand the effort that the body does to maintain homeostasis, which has threatened to be, to certain levels, upset.

 

Summary  

As childhood depression it is intending the inhibition to certain neurochemical mechanisms, which cause defective symptoms, almost accompanied by the compensating hyperfunction of other neurochemical mechanisms, from which symptoms of compensation come out.  The  mood fall's  symptom is or not always present. The depressive illness implicates always the whole body in its affective, intellectual, motor,  and neurovegetative components and will act again on the psychological and social relationships.  The depression can be present by itself, or it can be an accompanying  symptom of neuropsychiatric lesional forms  such as mental deficiency, cerebral palsies in children, epilepsy, syndrome of Down, etc.  In these last cases, beyond a primary depression of this type, we can find  even a secondary depression as the result of the awareness of one's own disability.  

 

Etiopathogenesis.

It appears more evident that all the pathogenic agents that can act on the central nervous system, - and I am speaking of physical, chemical, infectious mainly viral, and psychological agents -, elicit mainly a  unique brain defensive answer.

This runs through GABAergic mechanisms [in the range of reactions to stress].  The basic neurophysiological research found that GABAergic pathways, in the mammals and in the man, are  particularly fragile at the birth and in the early infancy period. Moreover in accord with  data of my clinical-therapeutic experience, the childhood depression is an illness where exists always  basic GABAergic unbalance.  

The causes of the childhood depression will be then mostly referred to physical, chemical, infectious or psychological  agents that acted in this critical period. This type of formulation modifies entirely the causality relationship, first because largely privileges, for a morbid condition that would seem only psychic, factors that  are mostly not psychological ones.  On the second hand, because those often pointed out as psychological causes of the child's trouble (altered mother-child relationship, for example) to  a deeper examination  usually get on to consequences.  

If in fact, for any of the not psychological causes that I shall list, the child's emotional threshold kept, and keeps altered and/or biological basic rhythms as the sleep and the feeding keep modified, it is not difficult that happens, as we found, that even better feelings  of a mother can drive to less emotional involvement.  Continuously crying babies, refusing to be feed, or, as worst,  with sleep troubles lasting many months, preventing the mother's sleeping, produce fatigue  and stress  in her ( and losing the sleep is a worse stress!).

The result of it  is that even the better mother, when not vocated for the holiness, will counter-react, in the better case with the affective indifference but, in the worse case -  luckily it happens rarely - with the murder of her son.  Between these two extremes all intermediate reactions are possible, with the result to impair the emotional mother-child relationship which is fundamental in early childhood. For this away then the child's trouble subsequently increases. In this way a self-perpetuating circle runs and it finds its point of departure on a not psychological agent of the psychic trouble, although becoming continually fed by the further trouble of the  mother-child relationship.

 If, as roughly it has been done for many years, and as often it keeps done, one just looks at the  maternal feeling of hostility, and judges it as the primary cause, not appraising its counter-reacting function. So one risks of not only misunderstand the exact dynamics of the actual trouble, but of applying therapeutic methods that, by force of it,  will not  give the hoped results.  

Moreover that these methods on the one hand implicate a mother's responsibility, and so they feed inadequacy and guilt feelings in her. On the other hand it is on this supposed guilty mother that therapeutic treatment should find its ground.  With this I do not want absolutely affirm that there are no childhood depressive troubles  whose origin is only psychological, usually maternal. There are of them, but they are much more rare than habitually is thought. For what  is my clinical experience, they don't reach the 10% of all the depressive forms I met.

It is possible they are even in smaller number, since some injurious agents did not get their best light.  Based on these criteria, we may understand that the depressive illness, when it is the only morbid clinical frame, has as etiological moments nearly all which are the causes of the mental deficiency. Of course, it occurs only when the injurious action has been not so strong. To that we can add many psychological causes. The first and the second ones however are such to lead to a reduced functioning of some neurochemical mechanisms, and to the hypercompensation of some others.

 When instead the depression is an accompanying symptom of lesional illnesses of the central nervous system, the psychological causes cannot  be primary agents. The psychological factors are the cause of that share of secondary depression that may always add to a primary depression of any origin.  When the childhood depression represents the only morbid clinical frame, I will distinguish so its causes:

- A hereditary predisposition (not still statistically well evaluated, but of an undoubted finding);

- prenatal causes: Everything that reduces the supply of oxygen to the brain of the embryo and of the fetus; Intrauterine infections; endogenous and exogenous intoxications, among the last ones I have to remember the following of the psychostimulant drugs abuse, from  smoking to hard drugs; burden anxiety states of the mother;

- perinatal causes, the more frequent: Accelerated delivery,  prolonged delivery, prematurity, postmaturity, twin birth,  complicated delivery,  neonatal respiratory distress, not high hyperbilirubinemia, low birthweight, umbilical cord wound around to the neck, or short, a caesarian section, even when previously decided, and not after a suffering and prolonging delivery, blood change for RH incompatibility;

- postnatal causes: Not heavy skull traumas, viral illnesses that produce light encephalitis (flu, measles, but mainly the whooping cough), not burden metabolic toxicoses, cardiac illnesses reducing brain oxygenation, followings of viral hepatitis, results of kidney illnesses, long-lasting physical illnesses prolong, psychic traumas (disturbed mother-child relationship, loss of one or of both parents, entry in a foundling hospital, family atmosphere seriously troubled).  

The above mentioned causes to different levels of the development of the child can naturally add, as usually happens: One somatic cause + one psychological cause, but even various somatic causes among them; Or still a hereditary predisposition + a somatic cause + a psychological cause, and so on.  The incidence of the depressive illness in  children, in its various forms, was rated from 1/6 to 1/3 of the children's population.  

 

Summary.

 One defensive reaction of the organism to pathogenic causes that strike the central nervous system, implicates GABAergic mechanisms. Such response is  not specific and it is such for traumas of physical, chemical, infectious or psychological origin. Among his effects, the lowering of the emotional threshold, which, in its turn,  may cause further troubles in psychological relationships, in particular, in childhood, in the mother-child relationship.  

The causes of the childhood depression, beyond a possibly hereditary predisposition, frequently, are the same that, when heavier, give the rise to the mental  deficiency.  They can be listed as prenatal, perinatal and postnatal causes. To these last we have to add psychological ones that, as primitive, are found only in childhood depression, when this represents the only morbid picture.  

 

Childhood depressions' frames of reference.

 The symptoms frame of reference of the childhood depression is multiform, and it may be different, according to the age, the heaviness of the illness, and compensations put into action. Every case, after the birth, will  have always both somatic and psychic symptoms, with an increase of the psychic symptoms since the adolescent age approaches.  

In the intrauterine period the typical symptom of response to the stress is the hypermotility (perhaps due to hyperfunction of exciting dopaminergic pathways not more adequately controlled  because the fall of the inhibiting [A] GABAergic powers).  

Further confirmation of a fetal depression comes from the meconium tainted amnyotic fluid, as seen when the amnyotic sack breaks up, at the delivery starting, and considered the equivalent of the post-natal diarrhea. In the immediate neonatal time, and in the first year of life the  more common defective symptoms are:

- sleeping reduction or loss, or alteration of rhythm sleeping-awakening (the baby has the day for his night); - reduction or loss of appetite;

- continuous crying;

- constipation;

- easiness to upper respiratory tract infections;

- pallor.    

 

Compensation symptoms are:

- a sleeping time increase (it drives to an increase availability of GABA neoproduction);

- increase of the feeding or frank overeating (it to a larger introduction of some precursors among which glucose and tryptophan);

- sucking the thumb (it drives to an activation of large brain areas);

- increase of the need of thermal-tactile contact with his mother, who becomes obliged to a closer relationship, erroneously judged as an overprotection (while it  has  a calming action);

-  temper tantrums ( the make a suprarenal incretion with a positive action on the low blood tension, and on the serotonin neoproduction);

- rocking or rocked (a calming action, for probable vestibular-limbic pathways);

- hypermotility (an  aggravation symptom of the depression).    

 

Other symptoms of not easy classification:

- not infectious gastroenterites, with diarrhea;

- persistence of the milk crust;

- easiness to the vomit;

- acetonemia, when the child is feverish;

- febrile convulsions;

- simple motor delay, or simple delay of the language.    

 

From the second year  to the entry in the primary school defective symptoms of the childhood depression are:

- sleep disorders, even only early-morning awakenings;

- poor appetite, or reduced foods' choice [ie. Hyponeophagia];

- easy crying;

- constipation;

- easiness to upper respiratory tract infections;

- pallor;

- asthenia;

- be sensitive to cool;

- sadness;

- isolation;

- solitary game, or with very few companions;

- behaviour difference between morning and afternoon ( some are more serene in the morning, others  in the afternoon ).  

 

 Compensation symptoms, in this time, are:

- overeating;

- greediness for sweets (it drives to increase the GABA neoproduction [throughout the Krebs' cycle];

- the active search of coffee or wine (euphoriant drinks);

- diet preference for the meat broth ( it contains glutamine and glutamate, precursors of the GABA); - sucking the thumb;

- accentuated dependence from his mother;

- temper tantrums;

- need to put himself to the centre of the attention (It increases the self-esteem?);

- the choice less aged companions for games (with less-aged children the level of his own abilities becomes suitable, and often, being then the more physically strong, he becomes the bossy person);

- rocking;

- "neurotic" masturbation (an adrenergic compensation the orgasm);

- hypermotility.

 

   I found these other symptoms, but I have not clear if they are defective or  compensation symptoms:

- stuttering;

- tics;

- sudden diarrheas, for no known reason;

- bruxism during the sleep;

- to talks in one's sleep;

- pavor nocturnus;

- mood variations, linked to weather changes;

- doing better during the summer;

- brotherly jealousy;

- bedwetting;

- loss of faeces;

- rituals before eating, or when going to bed;

- panic refusal to attend the nursery school (Is it similar to the school phobia?);

- simple delay of the language and modest motor delay.    

 

The entry in the primary school, by itself,  may reveal a masked depression in children that did not make any evident discomfort till that moment, or at least it seemed so.  Between 6 and the 11-12 years  we can note, as defective symptoms:

- sleep disorders (difficulty in falling asleep, or frequent awakenings during the night, or early-morning waking up);

-  poor appetite, or reduced foods' choice [ie. hyponeophagia];

- easy crying;

- constipation;

- easiness to upper respiratory tract infections;

- pallor;

- asthenia;

- be sensitive to cool;

-  frontal or  nape of the neck headache;

- sadness;

- emotional inhibition;

- touchiness;

- solitary game, or with less-aged friends;

- childish language; motor awkwardness;

- learning troubles, following attention, concentration, memory, ideation difficulties.    

 

I noted those compensation symptoms, in this period:

- overeating;

- greediness for sweets (it drives to increase the GABA neoproduction [throughout the Krebs' cycle];

- the active search of coffee or wine or alcoholic drinks (euphoriant drinks);

- diet preference for the meat broth ( it contains glutamine and glutamate, precursors of the GABA); - psychological troubles;

- tendency to the order and to the meticulousness (does have it anxiolytic action because it allows a control on the surrounding reality?);

-  active risk situations' search;

- "neurotic" masturbation;

-  need to put himself to the centre of the attention ( a form of turned to impose dependence?);

- he does the buffoon, mainly in the classroom ( it increases the self-esteem, by the growing of the consideration of the peers' group);

- tendency to  say lies or to the mythomany ( Another way for being in the centre of the attention?);

- dependence from the maternal figure or from a substitute ( The teacher, in the primary school);

- prevailing choice of less-aged children for the game;

- hypermotility.  

 

Other symptoms often found, but of difficulty frames of reference:

- stuttering;

- tics;

- bedwetting;

- loss of faeces;

- sudden diarrheas, without any evident cause;

- night bruxism;

- to talks in one's sleep;

- pavor nocturnus;

- rituals, even off before eating, or when going to bed;

- doing better during the summer;

- mood variations, related to weather changes;

- excess sweating;

- touchiness;

- self-pity;

- self-devaluation;

- avoiding of the obstacle;

- quarrelsomeness  and/or brotherly jealousy;

- certain forms of the school phobia.    

 

From the pubertal period and in the adolescence the childhood depression, as for its symptoms, get nearly all the features of the  adults' depression, inclusive the hope losing that can bring to the attempted suicide or to the suicide.  

It will miss however a symptom not infrequent in the adult age, from the fourth life decade. That  is the idea (to half between the depressive and the delusional one) of ruin.  

 

Summary.

 The symptoms of the childhood depression are inclined  to dissociate from those of the adult's depression, and so much more when the child  has fewer years. Primarily, the childhood depression has somatic symptoms of impaired basic biological rhythms (sleeping, feeding, evacuation), symptoms of delay in the development of certain acquisitions (language, motility and scholastic learning ) and psychic symptoms (from the crying to the mood depression).  

The psychic symptoms become more frequent when the subject approaches to the adolescence, an age in which doesn't exist many differences with the adult's depression of the adult. Compensation symptoms, or by somatic pathways, are increasing the functionality of GABAergic circuits, or are opposing the hypotension, or they act through psychic pathways, by reducing the anxiety or increasing the self-esteem.  

 

Prognosis.

This is a difficult matter about which the knowledge is  radically changing, either for what concerns the effects of the childhood depression in the developmental age, either even for what could have followings in the adult life.  

Of course the prognosis will be much worse as more serious is the depression, as less the body could put into action compensation mechanisms, when larger is the involved biological component, when first the depression came out and as more it lasted.  

The fact that the childhood depression was unknown for many years, and even today, in most cases, does not have its diagnosis,  does not have still brought a sufficient amount of research on this topic, either the depression was treated or not.  

If it not was not treated of, these are the clinical I think to should point up: - it is not clear if the body can overcome entirely, with only its strengths, any depression of any severity. Surely several symptoms, often the more striking, can modify,  or go down, or disappear. If however we do an accurate investigation, we realize that a several others remain even in the background. To this end  the non-rationally aware  learning  of substituting mechanisms plays its role.

Some of them  (I am referring to which acting on the adrenaline and noradrenaline as aggressiveness, neurotic masturbation, a risk situation's active search, etc.) can become an important  component for the building of the adult personality;

- in other cases however the body cannot overcome them by himself, neither can find an acceptable compensation form, and in these cases case the defective symptoms will be what build the subjects' personalities  ( I am referring now, for example, the so-called introvert character);

- the fall of  scholastic learning based on the depression can heavily affect on all  the academic careers;

- forms of false mental retardation on a depression base can settle in adult age in true mental retardation, even if, usually, of a modest degree;

- always more studies start to go out from which it results that psychiatric illnesses of the adult age (depression, schizophrenia, drug addiction)  have had psychopathological antecedent  of an ignored childhood depression. That happens with a greater rate than what would result from a random probability, (till over 80% of the patients). 

We do not know however which rate of formerly depressed children has developed a psychiatric illness in the adult age;   

- we started to suspect that in the preantibiotic era all a series of depressed children, with the symptom "easiness to upper respiratory tract infections", died by bronchopneumonia in their developmental age. With the current antibiotic therapies this prognosis has practically disappeared, but this may  have modified a  "natural" selection for the psychiatric illnesses. We observe that now we can to see Down's syndrome persons aged 40 years, while 40 years ago a Down child of 10 years was a very rare event.    

 

The therapeutic treatment, if well applied, can entirely modify the frame of the childhood depression, and if  early started and for a suitable period, to overcome the possible accumulated delays. It is possible, and there are the elements to think so, that a good antidepressant treatment  in childhood, can even prevent a possible increasing of psychiatric troubles of the adult age, but there are no studies on this topic.  

 

Summary.

 The prognosis of the childhood depression is function of the severity of the clinical frame, of the autonomous ability at compensation by the body, of the onset age and of the long lasting of the illness, and it is entirely different if a treatment was prescribed or not.  It is uncertain whether the depressed body can always  get over the illness by itself, even if some improvements can occur. The learning troubles  and the false mental retardation can become stabilized, and no  more able to reverse.

 There are some data that put an ignored childhood depression as the psychopathologic antecedents of certain psychiatric illnesses of the adult age, but a direct relationship did not found still adequate investigation.  If the childhood depression gets a suitable treatment, the prognosis is favourable, with whole remission. It is not discovered - even if there are elements for thinking so -   if a therapy in childhood would even  be  a prevention on some psychiatric troubles of the adult age.  

 

Therapeutic treatments.

 According to various pathogenic possibilities of the childhood depression, the efficient therapies on it are several.  When it has  a  somatic origin, or prevailing such, an experienced drug therapy  not can only get results in rather brief times, but can stabilize them, if well kept for a suitable time.  

When instead its origin is indubitably a psychological or relational one, an individual psychotherapy, or of the family, can be decisive by themselves, even if times and costs are well heavy.  Behavioral therapies that act on the reinforcement of the self-esteem, or on the lowering of the aggressive answers, or for a progressive desensitization against phobic stimuli can find exact justification, with successful perspective, in particular forms.

The same we can say for an occupational therapy, or even for a psychomotor therapy, since the effects of lowering of the so-called temper tantrums that this last therapy  has shown to possess.  Nothing finally forbids using contemporarily more of a therapeutic approach in the same subject, for having in this way a synergistic action.  

 

Summary.

 Following its origin, in the childhood depression we can use drug therapies, individual psychotherapies or family therapy, behavioural therapies, occupational therapy, psychomotor therapy or combinations among  some of these.
