Dysphasia involves difficulties swallowing due to issues in the brain, throat, or esophagus. -Paresis suffixes indicate types of weakness, such as hemiparesis affecting one side of the body, monoparesis affecting one limb, paraparesis affecting the lower limbs, and quadriparesis affecting all four limbs. The document provides links to further information on aphasia.
