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.

Article Synopsis
  • Alzheimer's disease (AD) is a neurodegenerative disorder that leads to memory loss and cognitive decline, often with mood changes and confusion, and the search for its causes is focused on the cerebral cortex through analysis of gene expression.
  • A study analyzed RNA expression in the frontal, temporal, and entorhinal cortex of AD patients and found key genes showing significant changes, particularly AEBP1 and COLEC12, which were also assessed in peripheral blood samples of late-onset AD patients.
  • The research connects the up-regulation of AEBP1 and COLEC12 to the TGF-β signaling pathway and suggests these genes could serve as important diagnostic markers for differentiating late-onset AD patients from healthy

Graduate Medical Education, Piedmont Athens Regional, Athens, USA.

Article Synopsis
  • Wernicke encephalopathy (WE) is a severe neurological condition primarily caused by thiamine (vitamin B1) deficiency, often linked to alcohol use disorder but also seen in malnourished individuals.
  • A case study discussed a 64-year-old woman with alcohol use disorder who showed symptoms like confusion and specific eye movement issues, with MRI revealing brain abnormalities indicating WE.
  • The key treatment for WE is high-dose intravenous thiamine, which improved the patient’s condition before discharge, highlighting the importance of early diagnosis despite the challenges due to the symptoms not always presenting in the classic triad.

Article Synopsis
  • Delirium is a serious brain condition often seen in the elderly, which can increase the risk of developing dementia later on, but its exact causes are not well understood.
  • Researchers compared three mouse models of delirium created by surgical anesthesia, inflammation, and neurotransmitter modulation, discovering that certain substances affected brain activity similarly to what is seen in delirium patients.
  • The study found that injecting mice with scopolamine caused temporary cognitive issues and increased activity without damaging cholinergic neurons, but it did disrupt hippocampal synapse functions, helping to shed light on how delirium might start.

Neuropsychologia

August 2023

Laboratory of Cognitive Neurorehabilitation, Division of Neurorehabilitation, Department of Clinical Neurosciences, University Hospital and University of Geneva, 1211, Geneva 14, Switzerland. Electronic address:

Article Synopsis
  • Disorientation often occurs after acute brain injuries or disorders like confusional states and dementia, with two main theories on its cause: damaged medial temporal areas affecting memory versus dysfunctional orbitofrontal areas leading to reality misinterpretation.
  • The study involved 84 patients hospitalized for neurorehabilitation, where their orientation to time, place, situation, and person was assessed, and correlations with executive tasks and memory were analyzed.
  • Results indicated that temporal context confusion significantly impacted disorientation, suggesting that challenges in distinguishing past from present experiences are critical in understanding disorientation following brain injuries.

  • - Methamphetamine (METH) is the second most commonly used addictive drug globally and can lead to severe psycho-neurological complications, including hyperammonemia (HAM), which is linked to mental health issues and encephalopathy episodes.
  • - METH and HAM cause similar neuropsychiatric symptoms such as psychosis, agitation, and memory impairment due to mechanisms involving neuronal damage, oxidative stress, and increased glutamate levels in the brain.
  • - Studies show that METH-associated HAM often results in mental state changes that improve with normal ammonia serum levels, highlighting the need for monitoring ammonia levels in METH users for better treatment outcomes.

  • Wernicke-Korsakoff syndrome (WKS) is primarily caused by thiamine deficiency, especially in alcohol-dependent individuals, but the optimal treatment dosage of thiamine has not been established through clinical trials.
  • Two randomized controlled trials were conducted to evaluate thiamine's effectiveness for preventing Wernicke's encephalopathy in at-risk patients and for treating symptomatic patients, using various dosages of parenteral thiamine.
  • The studies found no significant differences in cognitive or neurological outcomes between different thiamine dosages, indicating that higher doses may not provide additional benefits over lower ones.
