Diseases
We all say that, when we are with headache or in a bad mood, we are ill. But sometimes it's just the strees, because an illness have symptoms, from which we classify a type of disease. The symptoms could be fever, pain all over the body, etc.... There is a big difference with the brain, because the littlest of the haemorrages causes coma, or even death. But when in talk in brain diseases we can distinguish:
The disorders, that couldn't be related with the brain but, for example, with the spinal cord, that are related with an abnormality in some part of the C.N.S.(Central Nervous System), and/or P.N.S.(Peripheral Nervous System);
The infections caused, specially by bacterias and/or virus.
