纽约布法罗大学的AlanLockwood说,虽然耳鸣患者听到耳内发出持续的“铃”声,但这种病症却源自脑内。Lockwood领导的研究组应用正电子散射断层摄影术(PET)为有关脑区准确定位。上述研究结果是向此病治疗迈出的“关键性的第一步”。因为此病影响着1/3以上70岁以下的成年人。 Lockwood小组研究了一些耳鸣病人的脑血流量变化,这些病人一只耳朵内有持续的铃声,并且具有通过咬紧牙关控制铃声的“异常能力”。当病人控制此铃声时,PET荧屏显示,仅有患耳
Alan Lockwood of the University of Buffalo, New York, said that while tinnitus patients hear a sustained “bell” sound in their ears, the condition originates in the brain. Lockwood’s research team used positron emission tomography (PET) to locate the brain area accurately. The above findings are a “crucial first step” towards the treatment of this disease. Because the disease affects more than a third of adults under the age of 70. The Lockwood team studied changes in cerebral blood flow in some tinnitus patients who had sustained ringing tones in one ear and had “abnormal abilities” to control their ring tone by clenching their teeth. When the patient controls the ring, the PET screen shows only the affected ear
