When Cellular Structures Become Diseased: Mitochondrial Disorders

Many of our body's cells contain specialized structures known as mitochondria. Their primary function is to generate energy for the cell. In mitochondrial disease (mitochondriopathy), this energy metabolism is impaired, resulting in significantly reduced energy production. The underlying cause is a mutation in the genetic material. Mitochondrial diseases vary widely in severity and can cause a broad range of symptoms. Supplementation with Neotes α may help support the natural function of mitochondria.

What Are Mitochondria?

Mitochondria are cellular organelles that contain their own genetic material. They are present in all human cells that possess a nucleus (known as eukaryotic cells). Mitochondria are especially abundant in cells with high energy demands, including:

• Muscle cells
• Sensory cells
• Egg cells
• Nerve cells

The primary function of mitochondria is to carry out metabolic processes such as the electron transport chain (respiratory chain). During this process, energy is generated from glucose and fats for cellular use. Numerous proteins are involved in this complex system. When genetic mutations cause mitochondrial disease, energy production becomes impaired. As a result, organs with particularly high energy requirements—such as the nervous system and the eyes—are especially vulnerable to dysfunction.

What Are the Symptoms of Mitochondrial Disease?

In many cases, the first symptoms appear during childhood or adolescence. However, mitochondrial disease can develop at any age. It is considered a rare disease, affecting approximately one in every 5,000 people.

When mitochondrial energy production is impaired, cells initially lose function and may eventually die. Because mitochondria are present throughout the body, mitochondrial diseases can affect virtually any organ and produce a wide variety of symptoms. In most cases, symptoms gradually worsen over time. Common manifestations include:

• Muscle cramps or muscle weakness
• Visual disturbances
• Epileptic seizures
• Gastrointestinal disorders
• Heart or liver disease
• Diabetes
• Increased susceptibility to infections
• Short stature
• Stroke-like episodes

Mitochondrial diseases result from genetic alterations affecting either mitochondrial DNA or nuclear DNA. These mutations may be inherited or arise spontaneously.

To date, more than 250 genes have been identified that may cause mitochondrial disease. Researchers believe, however, that many additional disease-associated genes remain undiscovered. Although mitochondria have been known since 1886, mitochondrial diseases have only been recognized and diagnosed since the 1960s.

Research into Mitochondrial Disease Is Critically Important

Although mitochondria are microscopic, they appear to play a fundamental role in human health. Virtually every disease associated with impaired cellular energy production can ultimately be linked to mitochondrial dysfunction. Numerous well-known chronic degenerative diseases have been associated with impaired mitochondrial function, including:

• Alzheimer's disease
• Parkinson's disease
• Huntington's disease
• Amyotrophic lateral sclerosis (ALS)
• Cardiovascular disease

At present, there is no definitive evidence that mitochondrial diseases directly cause these conditions. However, mitochondrial dysfunction is widely considered to contribute to their development. Increasing evidence also suggests that autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, lupus, and Sjögren's syndrome may involve mitochondrial dysfunction. In addition, mitochondrial abnormalities have been linked to a broad range of cancers.

Good to know: Mitochondrial dysfunction has been associated with numerous chronic degenerative diseases—from Alzheimer's disease to cardiovascular disorders. Although a direct causal relationship has not yet been established, mitochondrial involvement is considered highly likely.

What Can Be Done for Mitochondrial Disease?

If symptoms raise a well-founded suspicion of mitochondrial disease, further evaluation is usually carried out at specialized medical centers. This includes various blood tests as well as examinations of organs that are suspected to be affected. Because hormonal disturbances frequently occur in patients with mitochondrial disease, regular monitoring of hormone levels is also recommended.

A definitive diagnosis is generally established through a muscle biopsy. Under local anesthesia, a small tissue sample is collected and examined microscopically.

Families affected by mitochondrial disease are advised to seek genetic counseling. Family pedigrees can help identify additional affected relatives and estimate the risk for future offspring.

Currently, mitochondrial disease is not curable. Treatment focuses on relieving symptoms and preventing complications. Depending on the individual's clinical presentation, associated conditions such as diabetes or epilepsy are treated accordingly.

One promising therapeutic strategy is to support mitochondrial function. This may be achieved through Neotes α. Its active ingredient, alpha-ketoglutarate (AKG), participates in numerous cellular and metabolic processes. The specialized formulation of Neotes α is also being investigated in longevity research.

In addition, endurance exercise has proven beneficial for many individuals with mitochondrial disease. However, patients should carefully monitor their individual exercise tolerance. Although early-onset disease often progresses more rapidly, optimal medical management combined with targeted nutritional support may improve both quality of life and life expectancy.
