Families dealing with the challenges of Autism Spectrum Disorder (ASD) need to know about the biological causes that cause its many different forms. ASD is mostly known for problems with social communication and repetitive activities, but more and more research is showing that it has a deep and interesting link to how cells make energy. Researchers are paying a lot of attention to the health and function of mitochondria, which are the “powerhouses” of our cells. To look into how important mitochondria are for brain health and how mitochondrial dysfunction in autism is linked to the particular problems that people on the spectrum encounter.

The Brain’s Energy Demands

The human brain is a very energy-intensive organ. Even when it’s at rest, it uses a lot of the body’s overall energy. Mitochondria create adenosine triphosphate (ATP), which is the main fuel for neural activity, to meet this huge energy need. Every brain function, from sending information between neurons to keeping cells healthy, depends on a strong and efficient power supply from mitochondria.

• Problems with Neuronal Communication: Synapses, the places where neurons talk to one other, need a lot of energy. This important process can be messed up by mitochondria that don’t work well.
• More oxidative stress: Mitochondria that are damaged can make more damaging free radicals, which can damage cells and cause inflammation in the brain.
• Neurotransmitter Imbalances: Making and controlling neurotransmitters (chemical messengers) requires energy.
• Less neuroplasticity: The brain’s ability to change and make new connections, which is important for learning and growing, might be limited.

The Connection to Autism Spectrum Disorder

Over the past 20 years, research has shown more and more that there is a big overlap between mitochondrial failure in autism and the traits seen in people with ASD. Studies have indicated that some people on the autistic spectrum show:

• Oxidative Stress Markers: People with ASD generally have high amounts of oxidative damage in their brains and bodies, which suggests that their antioxidant defense mechanism is not working properly. Mitochondria are involved in this.
• Metabolic problems: Sometimes, there are problems with particular mitochondrial enzymes or cofactors.
• Energy Deficits: Kids with ASD may show signs of persistent exhaustion, poor muscular tone, and developmental delays that are consistent with cells not making enough energy.

Not everyone with mitochondrial dysfunction in autism, but it is common in a large proportion of people with the disorder. This implies that it might be a factor in the wide range of symptoms, perhaps affecting cognitive performance, behaviour, and general health. This link makes it possible to create customized dietary and metabolic support programs that seek to improve mitochondrial health. This is a potential way to improve the quality of life for people on the autistic spectrum.
