Speech arrest in a dextral with a right mesial frontal astrocytoma.
A right-handed man had clustered groups of seizures characterized by speech arrest over a period of eight years. Later, speech arrest was accompanied by head-turning to the left and altered tone of the left limbs. An astrocytoma, centered in the right supplementary motor region, was identified. This case confirms the experimental data of speech arrest emanating from the right paramedian cortex of a right handed man.
