Affects of Frontal Lobe Damage Essay -- essays research papers
Damage to the frontal lobe cortex of the brain can cause difficulty in everyday activities. The frontal lobes role in people’s behavior includes executive processes, language, emotional expression and movement. Ryan Godfrey has difficulties in some areas of executive processes due to the damage tumors caused in his brain. Ryan and others with frontal lobe damage can benefit from knowing these deficits by taking steps to reduce their impact. The brain tends to compensate for damaged parts and a faith in God brings power to overcome deficits. Thus, behavioral difficulties for frontal lobe damaged patients are only a guideline not a box, for nothing is impossible for God to accomplish.      A 23-year-old man, named Ryan Godfrey was observed in his everyday behaviors to understand how he deals with frontal lobe damage. When he was 7 years, old the doctors discovered a grapefruit size benign meningioma tumor in his brain. After this, he had six more surgeries and his last one left him paralyzed on his left side. This was because most of his tumors were found in the right hemisphere, prefrontal cortex with his last surgery towards the premotor and motor cortex causing his paralysis. Ryan overcame being paralyzed with a desire to play basketball and video games. Today he is running sound for church, working full time and helping with student ministries. People like him can benefit from understanding the brain and its functions.      The frontal lobe comprises a third of the brain and it enables us to engage in higher cognitive functions such as planning and problem solving (Jonides & Smith, 1999). The frontal lobe is divided into 3 regions, the motor cortex, premotor cortex, and prefrontal cortex. The motor cortex is located in the precentral gyrus and directs fine motor coordination. The premotor cortex is involved in planning, organizing, and integrating body movements. The prefrontal is involved in executive functions, including short-term memory, working memory, decision making, and prioritizing behaviors (Wilson, 2003). Some of the frontal lobe disorders than can cause brain damage and behavioral changes are Huntington’s disease, infection, stroke, tourettes, dementia, epilepsy, Parkinson’s disease, tumors, closed head injury and traumatic brain injury (Chow, 2000).      People wi... ...
