Frontal Lobe Syndrome :: Brain Medical Neurology Essays

Frontal Lobe Syndrome Although volumetrically the frontlet lobes argon the largest portion of the brain their function remains somewhat gnarly (Jacobs, 2005). Even neuropsychologists have a difficult time creating test that accurately test facade lobe functioning. We do know however, that the frontal lobes are baffling in the storage of memories, concentration, abstract thought, judgment, and self control. The frontal lobe lies directly tin can our forehead (NINDS, 2005) It contains the primary motor cortex and the anterior cortex, which extend from the central sulcus to the anterior of the brain. The posterior part of the frontal lobe is the precentral gyrus which is specialized in the control of fine movements. The very most anterior portion of the frontal lobe is the prefrontal cortex. The neurons in this vault of heaven have up to sixteen time as many dendritic spines as neurons in the occipital lobe or primary visual cortex. As a result, the prefrontal cortex is qualifi ed to integrate a great deal of information (Kalat, 2004). For most mess the left frontal lobe controls language 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 other parts of the brain that control vision, respiration, fund pressure and gastrointestinal activity (NBTF, 2005).Damage to the frontal lobe results a surf of behaviors referred to collectively as frontal lobe syndrome. There are numerous ship canal 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 enquiry 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 located on on e of the lobes, or by create pressure on the frontal lobe, as is the case with meningioma, subdural haematoma or similarly meningitis (UNL, 2005).Frontal lobe syndrome results in the impairment of language, motor functions, kind behavior, abstract reasoning, and cognition. Furthermore, there is often a change in temperament (UNL, 2005). Although language remains fluent and in proper syntax, the overall occur of talking decreases. Patients have difficulty maintaining conversations and some even become mute. go functions are often uncoordinated and patients often have difficulty constructing tercet
