A 61-year-old man suffered an episode of transient confusion and anterograde amnesia after a Valsalva-related manoeuvre. The MRI diffusion weighted imaging (DWI) sequences showed a left hippocampal and two right parietal lesions that were deemed as acute. The MR angiography disclosed a high-grade stenosis in the right middle cerebral artery as was described by a transcranial colour-coded ultrasound as well. Ultrasound investigation of the jugular veins showed a right jugular venous reflux after a Valsalva manoeuvre...

OBJECTIVE: The etiology of transient global amnesia (TGA) is largely undetermined. The aim of this study was to investigate whether the prevalence of obstructive sleep apnea syndrome (OSAS), a condition associated with subtle changes in brain structures involved in memory processes, increases in subjects who have previously experienced a TGA episode. METHODS: Twenty-nine patients who had had a TGA episode were included. A case-control model was used, matching cases with controls by sex, age, and body mass index category...

This paper comments on a companion article, a first-person account of an episode of transient global amnesia written by New York Times reporter Trip Gabriel (Gabriel T. 2017. Cogn Behav Neurol. 30:1-4). Mr Gabriel describes having no memories of a cold, rainy day that he had spent on a sailboat competing in two races. The episode may have been triggered by his exposure to water. Afterward, the skipper recalled that Mr Gabriel had functioned fine on the boat, although after returning to shore he needed help finding his car...

Trip Gabriel
In this vivid first-person case history, political reporter Trip Gabriel describes experiencing a classic episode of transient global amnesia. He was near the average target age of 61. Although no cause has been established for the syndrome, as with many other patients his episode appears to have been triggered by contact with water: He was racing a sailboat. While remaining alert and handling complex sailing maneuvers, he suddenly developed amnesia that left him with no recollection of finishing two races, returning to shore, drinking a beer with his friends, needing help finding his car, and not knowing where he was or where he lived...

INTRODUCTION: Transient Global Amnesia (TGA) is short-term inability to form new memories despite otherwise normal neurological function. There is associated anterograde and retrograde amnesia. The memory loss is often accompanied by repetitive questioning and temporal disorientation while higher cognitive functions are preserved. The symptoms usually resolve by 24h. CASE REPORT: We present an interesting case of 31year old female who was planned for robotically assisted right sided pyeloplasty...

OBJECTIVE: To study the long-term risk of cerebrovascular events, seizures, and cognitive impairment in patients with transient global amnesia (TGA). PATIENTS AND METHODS: Data for all patients diagnosed with possible TGA in Olmsted County, Minnesota, between January 1, 1985, through December 31, 2010, were retrieved from the Rochester Epidemiology Project database. Transient global amnesia was defined clinically. End points were cerebrovascular event (stroke or transient ischemic attack), seizure, or cognitive impairment (mild cognitive impairment or dementia) during follow-up...

Transient amnestic syndromes are fascinating clinical entities and there are several subtypes. Transient global amnesia (TGA) is characterised by sudden onset of anterograde amnesia with repetitive questioning, lasting less than 24 hours. The pathophysiology of TGA involves the medial temporal lobes and hippocampi. Episodes of TGA are thought to involve venous congestion with Valsalva-like activities, vascular or migrainous mechanisms. In contrast, transient epileptic amnesia manifests as brief and frequent episodes of amnesia due to seizure activity in the temporal lobes...

Dimethyl sulfoxide (DMSO) is a cryoprotective agent used in storage of frozen stem cells in stem cell transplantation. Central nervous system side effects of DMSO such as epileptic seizures, stroke, transient global amnesia, and temporary leucoencephalopathy are rarely seen. Here, we report a pediatric patient who developed seizures after DMSO-cryopreserved stem cell infusion and whose magnetic resonance imaging of the brain demonstrated parietal and occipital focal cortical T2-signal intensity increase. DMSO toxicity should be kept in mind in patients who received cryopreserved stem cell infusion and magnetic resonance imaging may be helpful in differential diagnosis of central nervous system involvement...

The acute onset of isolated amnesia is an intriguing challenge for neurologist, because the lack of associated signs can be misleading for diagnosis. The most common cause is transient global amnesia (TGA), a benign condition, but rarely it results from abuse of substance/alcohol or cerebrovascular diseases. In the latter, the brain region involved is the hippocampus. We describe a patient with presenting symptoms of TGA, but affected by an ischemic hippocampal stroke. The computed tomography angiography helped the etiologic diagnosis showing an hemodynamic stenosis of the posterior P2P segment...

The epileptic syndromes, notably the temporal lobe epilepsy, frequently include memory disturbances. These memory disturbances may occur during seizures, i.e. ictal memory disturbances, or between seizures, i.e. interictal memory disturbances. Two atypical clinical epileptic syndromes should be pointed out in the elderly: the transient epileptic amnesia and the epileptic pseudodementia. Both represent potentially reversible memory disturbances and have a treatment based on antiepileptic drugs. Transient epileptic amnesia (TEA) is a subtype of medial temporal lobe epilepsy with late onset...

Transient epileptic amnesia (TEA) is a sub-type of mesial temporal lobe epilepsy, with amnesic seizures. TEA is characterized by recurrent episodes of amnesia. Diagnostic criteria are available for TEA, and these memory disturbances should not be misdiagnosed with transient global amnesia. The neuropsychological evaluation is normal, however, autobiographical memory impairment is present in 70% of the cases and accelerated long term forgetting in 44%. When a patient complains of memory disturbances, especially autobiographical memory, TEA must be considered especially if there was an amnesic episode and symptoms that suggest temporal epilepsia...

Transient global amnesia (TGA) is a disorder with reversible anterograde disturbance of explicit memory, frequently preceded by an emotionally or physically stressful event. By using magnetic resonance imaging (MRI) following an episode of TGA, small hippocampal lesions have been observed. Hence it has been postulated that the disorder is caused by the stress-related transient inhibition of memory formation in the hippocampus. In experimental studies, stress has been shown to affect both explicit and implicit learning-the latter defined as learning and memory processes that lack conscious awareness of the information acquired...

Learning and the formation of memory are reflected in various memory systems in the human brain such as the hippocampus based declarative memory system and the striatum-cortex based system involved in motor sequence learning. It is a matter of debate how both memory systems interact in humans during learning and consolidation and how this interaction is influenced by sleep. We studied the effect of an acute dysfunction of hippocampal CA1 neurons on the acquisition (on-line condition) and off-line changes of a motor skill in patients with a transient global amnesia (TGA)...

A 67-year-old right-handed woman experienced a sudden anterograde and retrograde short-term memory deficit that recovered on the next day. Magnetic resonance imaging (MRI) showed a spotty high-intensity lesion in the left putamen in the diffusion-weighted and fluid-attenuated inversion recovery images. Transient global amnesia due to lacunar infarction of the left putamen was diagnosed. Transient global amnesia is characterized by a sudden onset of anterograde amnesia that disappears within 24 hours. The cause of transient global amnesia is still uncertain...

A 67-year-old woman was diagnosed with transient global amnesia having presented with an abrupt and temporary disruption in her memory function. Her symptom onset came shortly after a visit to her general practitioner where she had performed bedside spirometry. Following symptom resolution, she was discharged home with reassurance.

Despite transient global amnesia is considered unusual in Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) and causal relation is still unclear, this report suggests to consider CADASIL in those patients with recurrent transient global amnesia, especially when MRI shows multifocal hyperintensities affecting the cerebral white matter or when it is followed by cognitive decline.

Acute perturbation of the hippocampus, one of the connector hubs in the brain, is a key step in the pathophysiological cascade of transient global amnesia (TGA). We tested the hypothesis that network efficiency, meaning the efficiency of information exchange over a network, is impaired during the acute stage of TGA. Graph theoretical analysis was applied to resting-state EEG data collected from 21 patients with TGA. The EEG data were obtained twice, once during the acute stage (< 24 hours after symptom onset) and once during the resolved stage (> 2 months after symptom onset) of TGA...

Neurological manifestations or disorders associated with central nervous system (CNS) are one of the most common as well as important clinical characteristics of antiphospholipid syndrome (APS). Although in the last updated (2006) classification criteria of APS its neurological manifestations encompassed only transient ischemic attack (TIA) and stroke, diverse 'non-criteria' neurological disorders or manifestations (headache, migraine, bipolar disorder, transverse myelitis, dementia, chorea, epileptic seizures, multiple sclerosis, psychosis, cognitive impairment, Tourette's syndrome, parkinsonism, dystonia, transient global amnesia, obsessive compulsive disorder and leukoencephalopathy) have been observed in APS patients...
