Gliblastoma may start as a single tumour and a few random symptoms. As the cancer progresses, a conglomeration of tumours may develop in different areas around the brain. More symptoms will crop up, with some of them linked to a tumour in a particular part of the brain. Treatment is usually focused on stopping the growth of the tumour and making the patient as comfortable as possible while attempting to prolong life through radiation and chemotherapy. Glioblastoma is most often fatal.

At least one overall symptom of terminal Glioblastoma may seem innocent enough: a headache. But when combined with a host of other symptoms, the headache may be indicative of a larger problem. It can increase to the point where it feels as if the head is about to explode from increased pressure inside the skull. Other general symptoms include loss of vision and sensory perception, nausea and dizziness.
While some symptoms may remain hidden to the casual acquaintance, others are readily noticeable. These include paralysis, often down one side of the body; seizures; a drastic change in personality; and speech that is slurred, incoherent or otherwise impaired.
Frontal Lobe Tumor
Some symptoms of terminal Glioblastoma can be attributed to a tumour in the frontal lobe of the brain. These can include vomiting, loss of memory or intellectual function and lack of emotion or another personality change. Convulsions, seizures and headaches are often the result of a frontal lobe tumour.
Temporal Lobe Tumor
Tumours in the temporal lobe, or the bottommost, central lobe of the brain, may create a different set of symptoms. These can include a lack of coordination or motor skills and inability to understand conversations or language.
Parietal Lobe Tumor
A tumour in the topmost, central lobe of the brain, or the parietal lobe, may cause another set of symptoms. Those affected may lose the ability to write; sensory and spatial distortions; and a tingling or numbness in the hands, feet and other extremities. Someone with a parietal lobe tumour may also lose positional awareness of his body.
