Cerveau
Du Bébé: Il Entend, Voit, Rêve, Compte Et Mémorise
Les recherches sur le cerveau des tout-petits, des nouveaux- nés ,
effectuées par Ghislaine Dehaene et de son mari Stanislas Dehaene, nous
révèlent que le cerveau des bébés n’est pas une ardoise vierge : Il entend, il voit, il rêve, il compte
et il mémorise. Quelle Merveille!
Ghislaine Dehaene, pédiatre et chercheure au CNRS, dirige l’équipe de Neuro-Imagerie
au centre de recherche Neurospin, à Saclay.
Elle étudie la façon dont se mettent en place la mémoire et la pensée
chez le tout-petit.
Dans une de ses recherches En Développement Cognitif Du Nourrisson,
on ne peut que s’émerveiller du développement du
cerveau chez le bébé : « Les bébés âgés de trois mois ont le sens des nombres »
Selon cette recherche, les bébés sont capables de
faire la différence entre 2 et 4, ou bien entre 4 et 8. On a pu le démontrer grâce à un outil (
l’électro encéphalographie ) qui
enregistre les réponses électriques du cerveau. Quand on montre à plusieurs reprises des
images différentes comportant deux canards, le cerveau du bébé s’habitue, il
répond de moins en moins. Mais si l’on change le nombre des canards, l’enfant
réagit, ce qui se traduit par une modification des ondes électriques
cérébrales.
Ghislaine Dehaene démontre aussi dans ses recherches que
le bébé n’est pas une ardoise vierge, il sait reconnaître les odeurs et les visages et déterminer que ce qu’il voit
est vivant ou pas. Le bébé reconnaît la
voix de sa mère jusque dans son sommeil. Les régions du cerveau sollicitées quand
l’enfant entend sa mère sont les régions auditives et aussi les zones des
émotions. Alors que quand le bébé entend
une voix étrangère, les zones des émotions ne répondent pas.

Depression In Preschoolers
Research shows that
depression is hitting kids as young as three
(( This text is a resume of Luby’s research on early depression))
BY HALA ELM
Depression is hitting at younger ages. Luby’s research from Washington University in St. Louis
as well as other studies now counter that view.
Joan
Luby, a principal investigator on the study, and professor of child psychiatry
at WUSM, has been following - for several years - a group of individuals
diagnosed with depression during their preschool years.
Her findings show
that young children report similar depressive symptoms as adults, but exhibit
the symptoms differently. Children, for
instance, who are depressed can’t find pleasure in any fun activities an and
they can’t have fun doing anything, from playing, to watching television, to
going on vacation. They are miserable most of the time regardless of activity.
Luby pointed out that depression in children as young as
three years of age is real and not just a passing grumpy mood. Luby points out that until fairly recently,
“people really haven’t paid much attention to depression disorders in children
under the age of six because children under six were too emotionally immature
to experience it.”
Luby found that
the preschoolers who came into her study and were diagnosed as depressed were
four times as likely to be depressed two years later compared to a control
group of healthy children.
An ongoing study
funded by the National Institutes of Mental Health and conducted by researchers
at Washington University School of Medicine (WUSM) attempts to pinpoint and
understand psychiatric disorders in preschoolers, and one aspect of the study
focuses specifically on preschool-aged depression.
The research
studied the temper tantrums of 270 children between the ages of 3 and 5. Those
children identified with having a major depressive disorder (MDD) either
exclusively, or MDD along with a
disruptive disorder such as ADHD ), showed more extreme aggressive behavior
toward a caregiver, parent, or object such as a toy. They also displayed self-injurious behaviors.
Beware that depression is now diagnosed in even toddlers!
The sooner our children get the right
diagnosis and the right treatment, the better the prognosis. A child today is ten times more likely to be
seriously depressed compared to a child born in the first third of this
century.
Almost one-third of thirteen-year olds have marked
depressive symptoms.
By the time they finish high
school, almost 15 percent have had an episode of major
depression.
One thing most child development researchers agree is
that when depression is diagnosed early and properly treated, kids almost can
be helped and feel better. And the
earlier you seek treatment the better.

Depression Signs in a
Preschooler:
Verbal skills are limited so will have trouble describing
feelings. Look for loss of pleasure in play (or inability to enjoy playtime) as
well as frequent and unexplained stomachaches, headaches, and fatigue;
overactive and excessive restlessness; irritability or low tolerance for
frustration; frequent sadness.
Signs and symptoms of possible early childhood
depression:
Hopelessness
Inability to enjoy activities
Persistent boredom
Children who prefer to be alone
