Dizziness has a wide variety of symptoms and therefore many possible causes. Some of the factors are important for all forms. The functioning of the organs of balance, eye movements, neck- and spine. In addition, the blood sugar, the intake of water, breathing (hyperventilation) and blood flow (also blood pressure) play an important role.
Dizziness has many forms and can consist of:
- Tendency to faint
- See the world go round
- Sense of rotation
- Losing the balance
- Being shaky
- See black spots
- Blurred / double vision
- Difficulty focusing
- Strange feeling under both feet (walking on cotton)
Disruptions in these systems can cause dizziness. Through bringing the neurological functional specialization, we are able cooperation of the involved accurate picture for them to plan the right treatment method set.
An important step towards an explanation for dizziness is the understanding of the structures and their function in our bodies and brains. The major structures that are active during the preservation of balance:
- Organs of balance
- Visual system (eyes)
- Proprioceptive system (muscle, joints and skin)
- Autonomous system (metabolism and blood flow)
Without knowledge of these four systems and the relationship is virtually impossible to judge properly about symptoms such as dizziness.
Below is a brief description of the 4 above-mentioned structures and systems.
- Organs of balance
These bodies register acceleration and deceleration of head movements. The orientation of the vestibular system in such a way that it is able to assess all the directions of movement.
- The visual system
The eyes allow us to orientate. Thus we can see where we are, where we are going and at what speed.
- The proprioceptive system
The feeling from the muscles and joints – especially from vertebral column, legs and feet – and tells us in what position the body is and at what speed the independent limbs move.
- The autonomous system
It regulates blood pressure and heart function. The brains are extremely sensitive to oxygen, so the supply must remain quite constant. A slight disturbance of only a few seconds, all symptoms.
Central Nervous System
All information from the above-mentioned neural structures are integrated into the central nervous system. Information from the vestibular system is transported via cranial nerve 8 and then arrives in the middle part of the brainstem, the pons. The information from the eyes is via cranial nerve 2 towards the upper part of the brain stem, the mesencephalon.
Information from the muscles and joints, of propriocepsis, is mainly through the posterior part of the spinal cord to the top where the suits in the brainstem. The autonomic nervous system sends information to the brain via nerve 10. This information comes in in the lower part of the brain stem, the medulla. All this information is integrated into the reticular formation of the brain and thus influence each other equally.
Integrated successfully in the central nervous system and plasticity
All information from the outside world and recorded from the body, analyzed and processed in the central nervous system. There is no structure in the body that is not under the supervision of the central nervous system. Maintaining the balance is a process that takes place in the central nervous system. It is a very complex process of integration of the aforementioned structures and information. Many times per second will be re-adjusted to a changed situation. The complexity of the human brain allows us to operate on two legs, while keeping the two arms as 'tools'.
Balance is an ongoing process and not a static data. The central nervous system receives continuous information about the service provided and activity to control it then improved. It is therefore subject to constant change and the brain adapts to it.
This process is extremely trainable. Train Affordability is the adaptability of the structures involved in improved function. Even if there are some structures worse functioning or broken is the brain to compensate for the preservation of the function. This accommodating ability called neuroplasticity is also called.
