Parents usually blame themselves when their child has ADHD but currently scientists believe that structural changes in the brain may be the cause.
The ADHD causes may be affected by, but are not caused by; o Television o video games o sugar or other foods o food allergies o bad parenting o bad schools or teaching o disruptive home life Researchers have identified factors that may play a role: o Biological issues could be the cause.
Scientists have been studying the brain and there is a link between the ability to pay continuous attention and the activity level in the brain.
New tools and techniques for studying the brain have been developed so scientists have been able to test more theories about ADHD causes.
o The areas in the brain that control attention used less glucose or sugar, meaning less activity.
So there is a suspicion that a lower level of activity in some parts of the brain may cause inattention in people with ADHD.
o During pregnancy drug use, toxins and hereditary problems may be a factor.
The damaging effects of cigarettes, alcohol and drugs can damage the unborn child and of course the developing and fragile brain.
Fetal Alcohol Syndrome (FAS) a condition that can lead to low birth weight, brain impairment, and certain physical defects show much of the same symptoms such as hyperactivity, inattention, and impulsivity.
o Drugs and alcohol affects the normal development of brain receptors.
Brain receptors help us to transmit incoming signals from our skin, eyes, and ears.
Current research suggests that drug abuse may harm these receptors.
Some scientists believe that such damage may lead to ADHD.
o Environmental toxins may contribute or worsen brain development or brain processes, which may be a cause of ADHD.
Lead is one such possible toxin.
Exposure to lead, which is found mainly in paint and pipes in older buildings has been linked to disruptive, violent behavior and to a short attention span.
Exposure to PCBs in infancy may also increase a child's risk of developing ADHD.
o Other research shows that attention disorders are likely to run in families, so genetic factors seem possible.
Children who have ADHD likely have at least one close relative who has ADHD.
It has been found that one-third of all fathers who had ADHD when they were younger have children who have ADHD.
Identical twins share the trait for ADHD making the case of genetic factors even more possible.
Having a child with ADHD can be difficult, but there is hope and many resources are available that can help.
There is advice and information on ADHD causes available from social workers, schools, doctors and support groups.
If you are concerned about toxins, and prescription drugs there are many Naturopaths and alternative medicines available.
