Retrograde Amnesia For Forty Years
We describe a patient who, in the absence of anterograde amnesia, experienced sudden onset of profound retrograde amnesia for the last forty years of his life. The amnesia encompassed all knowledge, including motor skills, acquired during these forty years. There has been no recovery in over eighteen months.

Abstract INTRODUCTION Previous simulations of Hebbian associative memory models inspired the malignant synaptic growth hypothesis of Alzheimer's disease (AD), which suggests that cognitive impairments arise due to runaway synaptic modification resulting from poor separation between encoding and retrieval.

Influence of Isoflurane on Immediate-Early Gene Expression [PDF]
Background: Anterograde amnesia is a hallmark effect of volatile anesthetics. Isoflurane is known to affect both the translation and transcription of plasticity-associated genes required for normal memory formation in many brain regions.

Hypoxia and retrograde amnesia [PDF]
Recent studies have questioned the phenomenon of hypoxia-produced RA on the premise that intracellular hypoxia cannot be produced rapidly enough to prevent the memory-consolidation process., Sixteen albino rats were trained to lever press for sucrose and were subjected to one of four treatments: shock only, hypoxia only, shock plus rapid decompression,

A case of acute methanol intoxication is presented, in which bilateral putaminal hemorrhage developed after hemodialysis. Even though the patient was initially comatose and profoundly acidotic, favorable outcome was achieved, with long-term neurologic ...

Amnesia is a deficit of memory function that can result from trauma, stress, disease, drug use, or ageing. Though efforts are made to prevent and treat the various causes of amnesia, there remains no treatment for the symptom of memory loss itself ...

Long‐Term Memory Engrams From Development to Adulthood
ABSTRACT Memories formed in adulthood can last a lifetime, whereas those formed early in life are rapidly forgotten through a process known as infantile amnesia. In recent years, tremendous progress has been made in understanding the memory engram—the physical trace of a memory in the brain—and how it transforms as memories evolve from recent to remote.

Transient global amnesia (TGA) is a self-limited disease characterized by isolated amnesia, which resolves within 24 h. In contrast, posterior reversible encephalopathy syndrome (PRES) is a potentially life-threatening disease that usually presents with ...

Post-concussion Vulnerability to Transient Global Amnesia
Few studies have investigated transient global amnesia (TGA) in the context of a concussion and the concussion sequelae following TGA. Here we review the case of a 43-year-old male with onset of transient global anterograde and retrograde amnesia 22 days

Noradrenergic mechanisms of arousal’s bidirectional effects on episodic memory [PDF]
Arousal’s selective effects on cognition go beyond the simple enhancement of emotional stimuli, sometimes enhancing and other times impairing processing of proximal neutral information.
