Summary
Topical linoleic and linolenic acids show promise for migraine prevention. A case study found safflower oil, rich in these fatty acids, effectively treated chronic migraine when other therapies failed.
Area of Science:
- Neurology
- Dermatology
- Pharmacology
Background:
- Chronic migraine presents a significant challenge, often inadequately managed by conventional therapies.
- Previous treatments like sumatriptan, amitriptyline, and topiramate failed for a patient due to efficacy issues or side effects such as vomiting.
- The search for alternative, well-tolerated prophylactic strategies is ongoing.
Observation:
- A 45-year-old woman with chronic migraine without aura explored topical treatments.
- She conducted an n-of-1 trial comparing safflower oil (rich in linoleic and linolenic acids) with olive oil (rich in oleic acid).
Findings:
- Safflower oil demonstrated effectiveness in relieving her migraine symptoms.
- This suggests a potential benefit of topical linoleic and linolenic acids.
Implications:
- Topical safflower oil may serve as a safe, accessible, and effective anti-inflammatory prophylactic treatment for chronic migraine.
- This approach warrants further investigation for broader clinical application.
- Fatty acid-based topical therapies could represent a novel migraine management strategy.

Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains two different acids, then its pH can be determined using one of several methods depending upon the relative strength of the acids and their dissociation constants.

Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...

When a force is applied to a linear spring, the restoring force increases proportionally with the amount of displacement. This behavior is described by Hooke’s law, which allows the work done on the spring to be determined directly from the force–displacement relationship. In this case, the force varies in a simple and predictable manner, making the calculation relatively simple.On the other hand, a nonlinear spring does not obey Hooke’s law. Its restoring force depends on...
