Concussions: What are they?

Blog by Dr Ainslie Morris (Osteopath)

You have heard the term, know the stories, heard the warnings and seen them occur on the sporting field, but what actually is a concussion?

Concussions are defined as a brain injury caused by a blow to the head or a violent shaking of the head and/or body. This does not mean you need to lose consciousness for a concussion to occur. The initial injury itself is to the brain and is due to the brain being pushed against the inside of the skull, some describe it as a bruising of the brain due to the impact. As well as the impact force, different speeds in which the different parts of the brain move can stretch and tear tissue due to the shearing force which can also injure the nerve tissue.

This impact and tearing of the brain tissue lead to symptoms and signs. Symptoms and signs can include:

  • Headaches Confusion
  • Dizziness Blurry vision (change in vision)
  • Memory Loss Lack of Coordination
  • Altered Sensation of body Nausea
  • Vomiting Ringing in the ears (Tinnitus)
  • Sleepiness Excessive Fatigue
  • Bleeding on the brain Altered heart rate

These can occur for a week, up to 12 weeks and possibly longer depending on the severity of the injury. There are a lot of other symptoms such as reaction times, which without pretesting a person would be unsure if it is still affected.

Concussions do not just happen on the football field or netball court. Most concussions occur from rapid movement of the head, including whiplash, or from a fall. They are a serious condition, but do not need to be scary when informed, treated and managed well with help of your doctor and allied health practitioner.

Free Migraine Seminar

Osteopath Dr Claire Richardson is hosting a free seminar explaining some of the causes, triggers and treatments for migraines – join us in person or online.

Migraines – Cause and Treatment

The word “Migraine” is used fairly loosely when describing a severe headache, however there are differences between headache (which can be severe) and migraine.
The word “headache” is a description of pain in the head, which can be caused by many different things, usually innocuous. Headache does not indicate the cause of the pain and thus, is not a diagnosis in and of itself. Not all severe headaches are a migraine, and not all migraines cause severe headache!

Rib Sprains

Rib sprains, as mild as they may sound, can actually be quite painful and disconcerting, and usually present as a sharp, localised pain on one side of the spine that is worse with movement and can also sometimes aggravated by deep breathing, coughing or sneezing.
