Sen. Edward Kennedy has a malignant brain tumor. The hospital treating Kennedy released a statement today saying that the tumor was found during tests after the senator had a seizure Saturday. The tumor is in his left parietal lobe.
From the Centre for Neuro Skills website:
Damage to the left parietal lobe can result in what is called “Gerstmann’s Syndrome.” It includes right-left confusion, difficulty with writing (agraphia) and difficulty with mathematics (acalculia). It can also produce disorders of language (aphasia) and the inability to perceive objects normally (agnosia).
