Frontal Lobe Syndrome :: Brain Medical Neurology Essays

facade Lobe Syndrome Although volumetrically the frontlet lobes are the largest portion of the wiz their function remains somewhat elusive (Jacobs, 2005). Even neuropsychologists have a difficult time creating test that accurately test frontlet lobe functioning. We do know however, that the facade lobes are involved in the storage of memories, concentration, compend thought, judgment, and self control. The frontal lobe lies directly behind our forehead (NINDS, 2005) It contains the primary labour lens cortex and the prefrontal cortex, which extend from the central sulcus to the anterior of the brain. The posterior bump of the frontal lobe is the precentral gyrus which is specialized in the control of fine movements. The actually most anterior portion of the frontal lobe is the prefrontal cortex. The neurons in this battlefield have up to sixteen times as many dendritic spines as neurons in the occipital lobe or primary visual cortex. As a result, the prefrontal cortex is abl e to integrate a enormous deal of information (Kalat, 2004). For most people the left frontal lobe controls vocabulary and the right non-verbal abilities (UNL, 2005).On the left frontal lobe is an area called Brocas area which allows thoughts to be transformed into words. In addition, there are many connections from the frontal lobe to early(a) parts of the brain that control vision, respiration, blood pressure and gastrointestinal performance (NBTF, 2005).Damage to the frontal lobe results a range of behaviors referred to collectively as frontal lobe syndrome. There are numerous ways of damaging the frontal cortex including lesions, tumors, and strokes. Lesions damage the frontal cortex when a blow to the head or a sudden change of motion causes the boney structure underneath the frontal lobes to tear the axons (as is the case with prefrontal lobotomy or leucotomy). A stroke can result in ventral and medial frontal lobe damage. Tumors can damage the frontal lobe by being locate d on one of the lobes, or by causing pressure on the frontal lobe, as is the case with meningioma, subdural hematoma or similarly meningitis (UNL, 2005).Frontal lobe syndrome results in the impairment of language, motor functions, social behavior, abstract reasoning, and cognition. Furthermore, there is frequently a change in personality (UNL, 2005). Although language remains limpid and in proper syntax, the overall amount of talking decreases. Patients have obstacle maintaining conversations and some even become mute. Motor functions are often unorganized and patients often have difficulty constructing three
