ADD: Over or Under Aroused. Natural Help.

0 Comment

    “The brain can be either over-aroused (speeded up) or under-aroused (slowed down), and in either case it will not function the way it is designed to.  If the brain is in over-arousal, we may be jumpy, hyper or anxious, looking at too much, trying to take too much in, paying attention to everything at once, nervous or upset.  If, on the other hand, the brain is in under-arousal, we may appear sleepy, lethargic or disinterested, not taking in what is happening, not caring about what is going on around us.  The hyperactivity can be an unconscious, automatic behavior to wake up the brain.  The alert professional looks for ADD sufferers with characteristics from both categories.  All cases do not look alike, but they all have problems with brain arousal states.     A way of conceptualizing brain arousal is to think of the intensity of light in a room.  If a dimmer switch controls that light level, we can have every level of light from complete darkness to brilliant light.  The “dimmer switch” of arousal in the brain is located in a part of the brain known as the thalamus.  Like a dimmer switch that adjusts light levels in a room, the thalamus automatically adjusts the intensity of arousal for the task at hand.
     For a restful sleep, the intensity is turned all the way down; for reading difficult material, it is turned to a more brilliant level.  Most activities fall somewhere between sleep and intense thinking.  This is done automatically, but in the case of many disorders, particularly ADD, the light (arousal level) usually stays adjusted to dim.  Individuals with ADD are found to have inappropriately low physiological arousal.  The set point for the dimmer switch (as in a thermostat) is set too low and does not automatically make the necessary adjustments.  In disorders of low arousal, the individual is often so slowed-down  he sits and stares, unable to focus or think clearly.  Sometimes, however, he becomes hyper, trying to turn the arousal level up.  This is an effort on the part of the brain to wake up or compensate for low arousal.  As you can see, this can account for both the hyperactive person as well as the hypoactive (slowed down) person.  pp.9-10.  From Getting Rid of Ritalin by Robert W. Hill, Ph.D. and Eduardo Castro, M.D..     The qEEG (brain map) clarifies the brain speeds and provides valuable information for corrective training.  Most improvement is permanent.
