Brain Tumors
What is it?
The cerebral or intracranial tumor is usually defined as tumoral expansive process anyone having origins in any of the structures containing the cranial cavity and brain parenchyma, meninges, blood vessels, cranial nerves, glands, bones and remains embryonic. In other words, this is an abnormal mass of emerging, growing and having origins in those structures. We can deduce that a tumor can damage the brain in two ways: by invading neighboring tissues (malignant tumor) or by pressing other areas of the brain due to its own growth.
Symptoms of Brain Tumors
Symptoms of intracranial tumors occur when brain tissue has been destroyed or when pressure increases in the brain. We shall see that this can happen in both malignant and in benign tumors. General symptoms begin with the alteration of certain mental functions, especially slowing and apathy, headache, vomiting, nausea, unsteadiness, generalized seizures and papilledema (swelling of the optic nerve due to pressure on the brain), the majority of these symptoms are caused by the presence of intracranial hypertension. There are more serious symptoms that causes tumor growth it self and depend on the topographical location of the lesion.
The most common are:
* Paresis (transient or incomplete paralysis).
* Crisis partial motor
* Aphasia (problems using language)
Apraxias * (problems for certain sequences of movements, such as buttoning a button)
* Agnosia (the person can perceive objects but not associated with the role they usually play)
* Visual field abnormalities (vision) There are other symptoms located in remote areas of the brain are called false symptoms are due to location and the same intracranial hypertension or the development of a syndrome of cerebral herniation (displacement of the brainstem due to pressure).
