Summary
Migraine and migraine-like headaches (MLH) are common in mitochondrial disorders (MIDs). MLH, a secondary headache, may link to stroke-like episodes and requires distinct treatment from migraine.
Area of Science:
- Neurology
- Genetics
- Rare Diseases
Background:
- Headache is a frequent symptom in mitochondrial disorders (MIDs).
- A comprehensive overview of headache in MIDs is lacking.
- Understanding headache patterns is crucial for managing MIDs.
Purpose of the Study:
- To review and discuss headache types, frequency, pathogenesis, and treatment in MIDs.
- To differentiate migraine-like headache (MLH) from other headache types in MIDs.
- To provide insights into the specific management of MLH in MIDs.
Main Methods:
- Literature review summarizing existing studies on headache in MIDs.
- Analysis of headache types, including migraine, MLH, tension-type, and trigemino-autonomic headache.
- Discussion of potential pathomechanisms and treatment strategies.
Main Results:
- Migraine and MLH are the most prevalent headache types in MIDs.
- MLH is a secondary headache, often associated with stroke-like episodes (SLEs) or seizures.
- Treatment for most headaches in MIDs is standard, but MLH may benefit from specific interventions like midazolam, l-arginine, or l-citrulline.
Conclusions:
- Migraine and MLH are key headache manifestations in MIDs.
- MLH presents distinct pathophysiological features compared to migraine, especially when linked to SLEs.
- Tailored treatment approaches are necessary for MLH in MIDs, differing from standard migraine therapy.

Animal Mitochondrial Genetics
9.3K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes
17.1K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Intrinsically Disordered Proteins
19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Export of Mitochondrial and Chloroplast Genes
4.2K
A eukaryotic cell can have up to three different types of genetic systems: nuclear, mitochondrial, and chloroplast. During evolution, organelles have exported many genes to the nucleus; this transfer is still ongoing in some plant species. Approximately 18% of the Arabidopsis thaliana nuclear genome is thought to be derived from the chloroplast’s cyanobacterial ancestor, and around 75% of the yeast genome derived from the mitochondria’s bacterial ancestor. This export has occurred...

The Inner Mitochondrial Membrane
4.8K
The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria. In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...

Bone Disorders
5.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
