A Tc-99m SPECT study of regional cerebral blood flow in patients with transient global amnesia
OBJECTIVES This study aimed to determine whether regional cerebral blood flow (rCBF) is abnormal in patients who have Transient Global Amnesia (TGA). METHODS We obtained noninvasive rCBF measurements using Tc-99m-ethyl cysteinate diamer Single Photon Emission Computed Tomography (SPECT) in 7 patients diagnosed with TGA within 4 days of onset of the amnestic episode while the patients were sti...
متن کاملTransient global amnesia: complication of cerebral angiography.
Transient global amnesia is a disorder of mentation in which there is an abrupt onset of memory loss and disorientation without change in consciousness. The disorder involves events and activities of the present and recent past , but leaves personal identification intact. There is no associated focal or sensory deficit [1]. An episode usually lasts for several hours. Memory returns to normal wi...
متن کاملTransient global amnesia or transient epileptic amnesia?
Sir, We read with great interest the letter of McCorry and Crowley concerning an attack of transient global amnesia (TGA) considered secondary to herpes simplex viral encephalitis. Some features of the reported attack are unusual. The patient was a relatively young person: 39 years compared with an average age of 61 with TGA. At the beginning the patient suddenly became ‘distressed’; he realize...
متن کاملTransient global amnesia mimics: Transient epileptic amnesia
We describe the case of a 79-year-old patient referred for suspected transient global amnesia, after an episode of anterograde amnesia which lasted 90 min. An EEG, performed after the episode, showed bilateral temporal electrographic seizures, orienting the diagnosis toward a transient epileptic amnesia. Transient epileptic amnesia is defined by temporal lobe epilepsy characterized by recurrent...
متن کاملLocal cerebral blood flow following transient cerebral ischemia. I. Onset of impaired reperfusion within the first hour following global ischemia.
Using the hydrogen clearance technique, local cerebral blood flow (LCBF) in 22 dogs was estimated at 6 parietal sites prior to and following 5 min of total global ischemia. Ischemia was immediately followed by an initial reactive hyperemia during which the electrocorticogram (ECoG) usually began to recover, and within the first 30 min, most of the LCBF's decreased to subnormal values. This onse...
