Punctate Hippocampal Hyperintensities on Diffusion-Weighted Imaging Following Epileptic Seizures: A Case Report.
Cureus
November 2024
Department of Neurology, Hiroshima Citizens Hospital, Hiroshima, JPN.
Punctate hippocampal hyperintensity (PHH) on diffusion-weighted imaging (DWI) is a well-known observation in patients with transient global amnesia (TGA), which is characterized by acute self-limiting episodes of anterograde and retrograde amnesia. These lesions occur unilaterally or bilaterally in the CA1 regions of the hippocampus, which are crucial for memory processes. PHH on DWI is well-documented in TGA but rare in other conditions.

Internal Medicine, Texas Tech University Health Sciences Center School of Medicine Permian Basin, Odessa, Texas, USA.
Article Synopsis
- Transient global amnesia (TGA) is a temporary memory condition often seen in older adults, marked by sudden memory loss that resolves within 24 hours while the person remains aware of their identity.
- A case study of a woman in her 60s illustrates how her acute memory problems were initially mistaken for a stroke after taking migraine and sleep medications, but were later correctly identified as TGA.
- This situation emphasizes the need to carefully distinguish TGA from other serious conditions to avoid unnecessary treatments and hospital costs, particularly since combining certain medications may increase the risk of TGA.

Department of Neurology, Juntendo University School of Medicine, Japan.
Both transient epileptic amnesia (TEA) and transient global amnesia (TGA) are clinically characterized by temporary amnesic symptoms. TEA involves recurring amnesic episodes, while TGA typically manifests as a singular occurrence. TGA rarely occurs repeatedly, known as recurrent TGA (r-TGA), which complicates differentiation, and raises the possibility of overlap between two disorders.

J Neurol
October 2024
Department of Neurology, University Hospital of Larissa, Faculty of Medicine, University of Thessaly, Mezourlo Hill, 41100, Larissa, Greece.
Article Synopsis
- - The study aimed to explore cognitive deficits during transient global amnesia (TGA) episodes, discovering that impairments extend beyond just episodic memory.
- - Researchers reviewed 1302 articles, ultimately including 17 in their analysis, and found that TGA patients experience significant issues with spatiotemporal awareness, anterograde amnesia, and working memory during acute episodes.
- - Although many cognitive functions remain normal, recovery typically starts with spatiotemporal orientation, followed by working and semantic memory retrieval, while episodic memory issues may last longer, with subtle memory deficits possible even after 24 hours.

Vertebral artery hypoplasia and hemodynamic impairment in transient global amnesia: a case control study.
Front Neurol
May 2024
Neurologie und Stroke Unit, Katholisches Klinikum Koblenz-Montabaur, Koblenz, Germany.
Introduction: The aetiology of transient global amnesia (TGA) is still a matter of debate. Besides ischemia of the mesial temporal lobe including the hippocampus, migraine-like mechanisms, epileptic seizures affecting mnestic structures, or venous congestion in the (para) hippocampal area due to jugular vein insufficiency have been discussed. We assessed the diameters of the intracranial arteries of TGA patients compared to controls to identify differences that support the hypothesis of reduced hippocampal perfusion as a pivotal factor in the pathophysiology of TGA.

Campus Klinikum Nürnberg, Paracelsus Medizinische Universität, Nürnberg.
Article Synopsis
- - Transient global amnesia (TGA) is a temporary condition primarily affecting older adults, causing short-term memory loss for new information, lasting 30 seconds to 3 minutes, while other cognitive functions remain intact.
- - Recent data suggests TGA occurs more frequently than previously thought, with about 15 cases per 100,000 people annually, and episodes typically resolve within 24 hours, but 10% may experience future episodes.
- - MRI scans often reveal small lesions in the hippocampus in TGA patients, but the precise causes and mechanisms are still unclear; potential triggers include physical exertion and anxiety, and reassurance for concerned relatives is part of managing TGA.
