Attention Deficit Disorder (ADD & ADHD)
Attention-deficit hyperactivity disorder (ADHD) is a common childhood disorder characterised by persistent and developmentally inappropriate levels of overactivity, inattention and impulsivity; a condition that can persist into adulthood. ADHD is the most common psychiatric disorder in youth with 9.5% of school aged children affected in Australia and New Zealand. This figure has risen with increasing awareness, as well as an actual increase, of the condition. The disorder not only interferes with the learning ability of a child, but also creates a great deal of stress in family life and interpersonal relationships.
Behaviour is affected in ADHD and is due to imbalances of the neurotransmitters dopamine and noradrenalin affecting the executive functions of the prefrontal cortex of the brain – the area of the brain involved in planning complex cognitive behaviours, personal expression, decision making and moderating social behaviour. Patients may have either too little of too much of these neurotransmitters, have defective receptor function and / or methylation defects on dopamine receptors that ultimately compromises the fluidity of neuronal membranes and neuronal synchronisation during attention demanding tasks.
Currently there are no biomedical tests for ADHD, so the condition is diagnosed by the observation of behavioural symptoms. The diagnostic criteria for ADHD are 9 symptoms in two areas of mental functioning: inattention and hyperactivity/impulsivity (see symptoms below). A child only needs 6 of these 9 symptoms in either area to obtain a diagnosis. There are around 500 different possible combinations of these 9 symptoms which means a child can present in a number of different ways and still reach a diagnosis of ADHD. Due to the variability of symptoms, ADHD has been classified into 3 subtypes:
- Predominantly hyperactive-impulsive: majority of symptoms are in the hyperactivity/impulsivity category
- Predominantly inattentive: majority of symptoms are in the inattentive category
- Combined hyperactive-impulsive and inattentive: 6 or more symptoms of each type.
Several lines of evidence support a disturbance in the gut / brain / immune (GBI) axis. The gut / brain axis is particularly affected as toxicity and food constituents have been identified as drivers of brain dysfunction in ADHD. Family studies also reveal a strong genetic link in ADHD, where multiple genes have been identified which involve dopamine receptors or transport. However it is also recognised that environmental triggers, such as heavy metals are shown to induce oxidative stress, lower intracellular glutathione levels and inhibit methylation in neurons, contributing to the ADHD phenotype.
Causes / Risk factors
Factors that are shown to be associated with ADHD are:
- Heredity: children with ADHD usually have at least one first-degree relative who also has ADHD and one-third of all fathers who had ADHD in their youth have children with ADHD.
- Gender: ADHD is more prevalent in boys; the male-to-female ratio is 4:1 in epidemiologic surveys and 9:1 in clinic samples.
- Prenatal and early postnatal health: maternal drug, alcohol, and cigarette use; in-utero exposure to toxins, including lead, dioxins and polychlorinated biphenyls (PCBs); nutrient deficiencies and imbalances.
- Abnormal thyroid responsiveness (possibly caused by exposure to pollutants during perinatal period).
- Learning disabilities, communication disorders, and tic disorders such as Tourette’s syndrome.
- Nutritional factors: allergies or intolerances to food, food colouring, or additives.
- Environmental exposures: chronic exposure to lead, mercury and other toxic metals have been linked to a variety of neurobehavioral conditions in children.
- Extreme or pervasive psychosocial stressors (such as marital discord or parental psychopathology); in isolation probably not a major cause of ADHD, but may contribute in combination with other risks.
Signs and Symptoms of ADHD
Diagnosis is based on having 6 symptoms of either or both of the following subtypes:
- Fails to give close attention to details or makes careless mistakes
- Has difficulty sustaining attention in tasks or play activities
- Does not seem to listen when spoken to directly
- Does not follow through on instructions and fails to finish schoolwork, chores, or duties at work
- Has difficulty organizing tasks and activities
- Avoids, dislikes, or is reluctant to engage in tasks that require sustained mental effort
- Loses things necessary for tasks or activities
- Is easily distracted by extraneous stimuli
- Is forgetful in daily activities
- Fidgets with hands or feet, or squirms in seat
- Leaves seat in situations where remaining seated is expected
- Runs or climbs excessively in inappropriate situations (in adolescents or adults, may be limited to subjective feelings of restlessness)
- Has difficulty playing or engaging in leisure activities quietly
- Acts as if “driven by a motor”
- Talks excessively
- Blurts out answers before questions are completed
- Has difficulty awaiting turn
- Interrupts or intrudes on others
In order to obtain optimal results, the patient might consider a holistic approach that integrates several treatments to address biochemical, physiological, energetic, emotional and/or spiritual imbalances.
Biomedical Treatment for ADHD
Biomedical or Nutritional and Environmental doctors and practitioners use treatments that include Diet, Nutrient Therapy, Detoxification and treatment of infections.
It is recommended that a patient consult a qualified Practitioner to assess their symptoms and case history and explore their dividual need to:
- Screen for food sensitivities and allergies
- Improve gastro intestinal health to support the vegas nerve and brain and immune function
- Support neurotransmitter function
- Supply fat soluble nutrients for brain structure and function
- Reduce toxicity and heavy metal accumulation
- Eliminate germs (bacteria, yeast, virus, parasites) to reduce immune response and nutritional deficiencies that can disrupt brain development and function
- Address nutritional deficiencies/Provide essential nutrients
- Regulate blood glucose and establish healthy eating habits
