Brain is perhaps the most important organ in our body as it organizes and leads everything. Brain has very complex functions and is said that we do not use its total capacity, so this way we cannot find all about us and about  all we would be able to do. There are not known so many things about brain and many mysteries about it have not been revealed yet. If we would find out more about it, maybe the way we see life would change and we would have the great possibility to discover new things about humanity and how we evolved. With the new technology and devices, we have the possibility to see the activity of the brain while sleeping, but not only. Numerous tests have been made and interesting things have been discovered.

On the other hand, a brain disease can develop gradually and not always has obvious symptoms. So, because of this, a brain disease is often hard to discover and so to cure. Fortunately, the technology we have today enables us to find out more and faster things about a potential brain disease than in the past. A brain disease can be caused by an accident or by a lot of other things. As mentioned above, we still do not know very much about brain, so we do not know the true causes of a brain disease. There are many theories about a brain disease, but nothing sure or demonstrated very clearly exists. Psychological problems can lead to a brain disease, hereditary causes, genetic and many others. Diseases of the brain can sometimes be cured, but other times they can only be temporary treated to improve the patient’s health and stop the brain disease from evolving fast. 

Diseases of the brain are a challenge for medicine and doctors and scientists still make a lot of studies to find out new things or to check if a hypothesis can be demonstrated or not. Today, doctors and scientists struggle to find ways of preventing a brain disease and discover in time the potential predispositions that patients can have. Many people die of a brain disease and this can sometimes happen very easy and in a very short time.
