Tumors in the cerebrum, which controls movement, may cause weakness or numbness to the body. This weakness is often limited to one side of the body. Tumors in the Broca's area of the cerebrum can cause speech difficulties. In extreme cases, the patient may have problems understanding words.
Meningiomas, which develop in the meninges, are common primary brain tumors, representing approximately 37% of all brain tumors. [15] The incidence rate for meningiomas is 9.51 per 100,000 people. [9] Unlike gliomas, more than 98% of meningiomas are nonmalignant [15]. The 5-year survival rate for nonmalignant meningiomas is approximately 91%. [9]
The causes of frontal lobe disorders can be closed head injury. An example of this can be from an accident, which can cause damage to the orbitofrontal cortex area of the brain. [2] Cerebrovascular disease may cause a stroke in the frontal lobe. Tumours such as meningiomas may present with a frontal lobe syndrome. [11]
Extension of craniopharyngiomas into the third ventricle may cause hydrocephalus. Meningiomas can develop from the arachnoid layer. Tuberculum sellae and sphenoid planum meningiomas usually compress the optic chiasm from below. If the meningioma arises from the diaphragma sellae the posterior chiasm is damaged. Medial sphenoid ridge types can ...
