Temporal lobe syndrome

An overview of the temporal lobe of hearing and speech center, central auditory, olfactory center, taste central location. Temporal lobe lesions, either Attack Symptoms and non-sexual attack symptoms. Cause pathogenesis brain injury, support temporal lobe cortex and temporal lobes deep artery occlusion, the temporal lobe tumors may lead to temporal lobe damage, corresponding clinical symptoms. A clinical performance. Temporal Lobe Epilepsy : patients with paroxysmal memory performance barriers, a trance-like state of mind, speech disorder, psychomotor agitation. orientation and emotional obstacles illusion, the illusion, and so on. 2. Automatic Disease : performance paroxysmal unconsciously self-injury, wounding, impulsivity, and destroy the spirit sport exciting, and involuntary to chew and repeated swallowing, lips and actions, paroxysmal first reverse eyes, and explore such action without purpose. 3. Aphasia : Broca's area and the posterior temporal lobe and the Wernicke's area on the leaf edge to the top of the transitional zone of damage, generate motor aphasia and sensory aphasia. 4. Hearing impaired : bilateral transverse back lesions appeared hearing impairment, cortical performance for the Deaf. 5. Paralysis : temporal lobe lesions violations of campaign areas, there contralateral central facial paralysis or upper limb paralysis. including facial muscles of lower limb paralysis or hemiplegia. 6. Ataxia with vertigo : patients showed trunk ataxia, standing and walking obstacles fingers appeared refer to the space phenomena. Temporal lobe diffuse lesions, the initiative appeared vertigo, and accompanied hallucinations. 7. Vision defect and nystagmus : temporal lobe lesions, there will be symmetrical or asymmetrical binocular vision defect and the upper 1 / 4 quadrant Blind. And often found thick nystagmus. 8. Fundus and pupil changes : temporal lobe tumor can fundus palilledema, temporal lobe epilepsy, terrorist uneasy restlessness often larger pupil. Differential diagnosis (1) of intracranial tumors (intracranial tumor) symptoms of the disease due to focal different tumor sites were mixed, the central ago, after the return to the tumor, often first appeared limitations epilepsy, and can lead to lesions in the contralateral limb paraparesis, Mr paralysis, pyramidal signs, but little paralysis. (2) basilar artery thrombosis (basilar artery thrombosis) performance Vertigo , nystagmus, ataxia, quadriplegic. Ataxia mainly for the limbs of a total economic uncoordinated campaign. Paralyzed by more than a few hours or days - 2 reached its peak. (3) cerebral thrombosis (cerebral thrombsis) more than 50 ~ 60-year-old incidence. Side limb numbness or weakness of prodromal symptoms are often in a quiet state or sleep onset. Lesions located in the middle cerebral artery of the central support, the performance of hemiplegia, Partial body sensory dysfunction and facial nerve, and the hypoglossal nucleus palsy.
