Migraines

Migraines

Approximate reading time: 3 - 4 minutes

Migraines are a common neurological condition affecting almost a quarter of Australian households.

There are many different migraine symptoms:

  • Headache
  • Nausea / vomiting
  • Dizziness / unsteadiness / vertigo
  • Motion sensitivity 
  • Light sensitivity
  • Noise sensitivity
  • Visual changes such as lines or blobs in vision
  • Tingling or numbness 

Migraines are not just a bad headache. Headache is one of many symptoms of a migraine. Some people suffer severe headaches that are not migraines. Others suffer from migraines without any headaches.

Healthcare providers will make a diagnosis after asking a lot of questions. Sometimes they'll get an MRI done but most of the time it's not needed.

After being accurately diagnosed, you can then get the most appropriate treatment.

Migraines are also complicated by the overlapping conditions like

  • Anxiety and depression
  • Heart disease and high blood pressure
  • Stroke
  • Restless leg syndrome


What causes migraines?

Migraines are complex! Many factors contribute:

  • Neurological (brain & nerves)
  • Vascular (arteries & veins)
  • Chemical (hormones & neurotransmitters)
  • Immunological

This is why so many migraineurs settle for less frequent and less debilitating migraines, rather than expecting to find a cure.

Migraine sufferers have sensory hypersensitivity. Their brain has an exaggerated response to small sensations. Seemingly inconsequential triggers get a big reaction! LIke flickering lights causing a migraine attack.

Scientists believe that the brain goes quiet. Generally starting in the visual or touch areas of the brain. This then spreads to other brain areas like a ripple in a lake. This is called cortical spreading depression. 'Depression' is not referring to feeling down but the decrease in electrical activity in the brain.

This decreased brain activity is believed to cause the aura symptoms such as visual changes, weakness and tingling experienced by 30% of migraine sufferers. This dumps lots of chemicals in the brain. These chemicals activate the pain fibres around the head. That's how the headache comes about.

Interestingly, this is a similar mechanism to concussions (Seifert 2018). There's more similarities. Both have similar symptoms, both more prevalent in females and both can be exacerbated by hormones.

Research also shows changes in the brain chemical messengers - called neurotransmitters. Dopamine levels drop during a migraine attack. It passes messages on between nerves. Dopamine is the ‘feel good’ neurotransmitter which helps regulate emotion, motivation & sensory perception.

And then there's there's the good old theory - vascular changes. This was first talked about in the second century (Mason & Russo 2018)! The arteries around the head get bigger giving the pulsating headache. These blood vessels then release more pro-inflammatory chemicals.


Yep - migraines are complex. Researchers are still debating the true cause of migraines. Studies continue to be done every year with new findings.

What treatments options are available?

A comprehensive approach is often required. The different causes need to be addressed: nervous system sensitivity, chemical imbalances, blood vessel changes and immune system activation.

Just like Goldilocks, it is important to have not only the right treatment but the right amount of treatment. Too much can trigger a migraine and not enough can slow progress.

After GPs, pharmacists and dentists, Chiropractors are the most frequently sought after health practitioners for migraines. Many migraineurs respond well to manual treatments such as spinal adjustments, massage and home rehabilitation exercises.

You may benefit from a holistic approach to migraines such as addressing:

  • Joint and muscle restrictions and tightness in the neck, shoulders, jaw and upper back
  • Poor posture and faulty movement patterns
  • Over-responsive nervous systems
  • Identifying and eliminating triggers
  • Calming down the immune system
  • Cleaning up the chemical "dump"
  • Reducing inflammation

We believe in a team approach

We know that migraines are complicated. That's why we work together to get you the best results.

Some people work with us alongside their GPs, neurologists or pain management specialists while others don't require medication.

Did you know we have "two" clinics?

1. Bricks and mortar in Moonee Ponds, Victoria

2. Virtual online clinic

Chiropractor Dr Cassie comes from generations suffering from migraines and headaches. At a young age, she is fortunate to have found a solution which still works for her and her family. This is one reason why she sought to become a Chiropractor. After completing her Masters in Clinical Chiropractic, Cassie has gone on to study neuroscience and brain-based therapies for complex pain patterns such as migraines.
