#TRANSIENT GLOBAL AMNESIA PATIENT HANDOUT FULL#

We did not identify any precipitating events prior to the onset of transient global amnesia.Ĭopyright © 2022 Elsevier Inc. Patient information You have visited the emergency department or neurologist in the hospital. In addition to hypertension, individuals with transient global amnesia had similar cardiovascular risk factors as the general population. We found that nearly 50% of patients with transient global amnesia had hyperintense hippocampal brain magnetic resonance imaging lesions. There was no higher incidence of migraine in transient global amnesia patients (13%). It is often wrongly diagnosed as a transient ischemic attack (TIA) or 'mini' stroke. Stress and exercise preceded the onset of transient global amnesia only in 13% and 16% of patients, respectively. Thirty patients with transient global amnesia underwent CTP at a median latency of 5.9 hours (interquartile range, 4.3-9.7 hours) after symptom onset. Transient global amnesia is a unique and relatively common neurologic event that is poorly understood and frequently misdiagnosed. DWI were acquired at B value of 1000s/mm 2 in 4 2patients, 2000s/mm in 2 patients and both 10s/mm. The incidence of hypertension in patients with transient global amnesia was higher than in the general population. MRI brain was performed with a 3T scanner on 11 patients and 1.5T scanner on 1 patient.

Most lesions were located in the CA1 subfield. After the episode, the individual has no recall for the events during the period of TGA, but there are no. During the episode, there are no visual, motor, sensory, or brain stem abnormalities. Patients classically ask many questions repeatedly. Of those, 65% had unilateral lesions, 82% were left-sided, and 28% were right-sided. Transient global amnesia (TGA) is an episode of total amnesia that lasts little more than 24 hours. Hippocampal brain magnetic resonance imaging lesions were detected in 47% of patients with transient global amnesia. The incidence of brain magnetic resonance imaging lesions was analyzed for the coexisting cardiovascular risk factors and precipitating events. In this retrospective, an observational study we assessed brain magnetic resonance imaging in 38 consecutive patients with transient global amnesia. Magnetic resonance of the brain including diffusion-weighted imaging of patients with transient global amnesia revealed the presence of punctate hyperintense signal abnormalities in the hippocampus.Īnalysis of the presence of hippocampal lesions in brain magnetic resonance imaging in patients with transient global amnesia and the possible influence of additional factors on their appearance.

Transient global amnesia is a benign syndrome characterized by a sudden onset loss of anterograde amnesia with full recovery.
