Children and teenagers get stigmatized for their emotional behaiviour. Fits of depression, lethargy, aggression, and crying are ascribed to "raging hormones" and the natural emotional vulnerability of youth that hasn't hardened up against the increasing burden of regrets and heartbreaks that has, unfortunately, come to characterize adulthood.
However, I believe it is one of the great misconceptions of Western medical philosophy, which is based neither wholly in philosophy nor wholly in medicine, that body and mind are so seperate that one should be "in control" of the other. The thoughts and feelings that every human being holds dear to his/her identity are produced by biological processes; those very same processes are also affected by emotional triggers. The Journal of Psychosomatic Research is dedicated to elucidating those connections, which we all know intuitively on some level, when we feel our hearts beat quickly at the sight of a disaster or a loved one, but that we forget are also the result of very physical reactions, and not just floating ethereally above our heads in mystical emotion clouds.
One example I wanted to draw some attention to is breath-holding spells in children. Maybe you remember having done this yourself; getting so annoyed at your parents that you threatened to hold your breath until you passed out? Parents would be tempted to write this off as being cursed with a difficult monster of a child, who would hopefully grow out of it soon. However, research from as early as 1943 has linked breath-holding spells to iron-deficiency anaemia. This is hypothesized to be because of several functions of iron in the body, including oxygen transport to the brain and central nervous system, the neuro-protective effects of erythropoietin, a hormone related to red blood cell production.
So if your children are acting out, don't be too quick to judge them as just trying to cause trouble. Many nutrient deficiencies express themselves almost as mental diseases: Pellegra, or vitamin B3 deficiency, causes dementia, and even just common old hypoglycaemia causes increased irritability, depression, anxiety, and other symptoms very much of the moody variety.
It is always important to bear in mind that our minds are a function of our bodies. If someone appears to be going a bit crazy, it is important to look first at their physical health, because the body is more than a robotic transport vessel that thauls your brain around; the mind is the sum and miracle of the body it inhabits.
