Approximately 1 in 68 children will be diagnosed with spectrum disorders. Spectrum disorders include ADD and ADHD, and many children also experience significant learning difficulties. One important and often overlooked risk factor associated with spectrum disorders is mitochondrial dysfunction.

Children with spectrum disorders are up to 500 times more likely to have mitochondrial dysfunction.

What are mitochondria?

Mitochondria are found in every cell of the body. The function of mitochondria is to produce energy for the cell, which is why they are often referred to as the powerhouse of the cell. During the process of energy production, cells generate free radicals and other metabolic byproducts. If these substances are not properly cleared, they can lead to cell damage or cell death.

In tissues such as skin or the gastrointestinal tract, this process is less critical because cells are replaced frequently. In brain cells, however, this is far more serious. Neurons have a much longer lifespan and are not easily replaced. Proper mitochondrial function is therefore crucial for brain health, neurological development, and gut function.

Neurons require significantly more energy than other cells. When mitochondria are not functioning properly, nerve cells in the brain may struggle to form new connections. If these connections cannot form, learning difficulties may occur. Mitochondrial dysfunction can also lead to calcium imbalances that keep nerves in a hyper-excited state, contributing to hyperactivity. This process can become self-perpetuating if not addressed, allowing neurological dysfunction to progress rapidly.

Images often demonstrate the difference between a healthy brain cell and one affected by mitochondrial dysfunction, highlighting the structural and functional changes that occur at the cellular level.

Mitochondrial dysfunction may also contribute to a wide range of gastrointestinal symptoms, including constipation, diarrhea, bowel irregularities, and food sensitivities. This reflects the close relationship between mitochondrial health, gut function, and the nervous system.

Additional factors that may increase stress on the central nervous system include infections, environmental toxins, spinal subluxations, dysbiosis, and decreased glutathione levels. These stressors can contribute to programmed cell death and further neurological compromise.

Early signs of mitochondrial dysfunction may appear on standard blood tests as elevated ammonia levels or low carnitine levels. In functional medicine, more detailed insight is often gained through organic acids testing, a urine test that evaluates metabolic byproducts related to mitochondrial function. Organic acids testing can help identify dysfunction and provide guidance on targeted nutritional and metabolic support.

If you are a parent of a child experiencing ADD or ADHD, you may be interested in learning more about how functional medicine testing, including organic acids testing, may help identify underlying metabolic imbalances.
