A new study by the Gladstone Institute of Neurological Disease and UCSF team found that apoE3 can inhibit memory problems associated with Alzheimer's disease, while apoE4 cannot. This discovery could lead to the development of new drugs simulating apoE3's protective quality.
Researchers found that a short-term drug regimen can reverse working memory loss in monkeys treated with antipsychotic medications. The study suggests improved treatment strategies for people with schizophrenia, Parkinson's disease, or age-related memory loss.
Researchers have found that memory uses separate pathways for various types of information, including visual and sensory inputs. This is achieved through the hippocampal memory system, which receives signals from different areas of the brain.
Researchers at Wake Forest University School of Medicine are testing whether an extract from the leaves of the ginkgo tree can slow memory loss, dementia, and Alzheimer's disease. The six-year clinical trial will enroll 2,000 participants and evaluate the effect of 240 milligrams of ginkgo daily on memory function.
Researchers found that older adults can compensate for cognitive decline by using unique brain areas, including the hippocampus, to support performance. This suggests that aging brains are more resilient than thought, with exciting implications for memory rehabilitation.
Researchers at WashU Medicine found that high doses of cortisol, produced in response to stress, can significantly impair memory performance after several days. Memory impairment was seen only in those who received a high dose of cortisol and only after four days of treatment.
New research from Washington University in St. Louis suggests that false recall in older adults with Alzheimer's is related to attention breakdowns rather than memory decline. The study found that older adults are susceptible to creating false memories, which challenges the idea of a broad general decline in all memory-related functions.
The NIA-funded Memory Impairment Study aims to test two drugs to slow or stop the conversion from mild cognitive impairment (MCI) to Alzheimer's disease (AD). Participants will be randomly assigned to receive placebo, vitamin E, or donepezil, and the study will be conducted at 65-80 medical research institutions in the US and Canada.
Researchers at NYU School of Medicine have developed a method to measure anatomical changes in the entorhinal cortex, a key memory center in the brain. This technique uses MRI scans and reveals that patients with very mild Alzheimer's disease show significant shrinkage in this area compared to healthy volunteers.
Neuroscientist Michela Gallagher's research reveals that cognitive decline in old age is not caused by dying brain cells, but rather by the natural aging process. The study used rat models to show that neuron losses are confined to populations of cells with limited memory function.
Researchers propose that an inactive enzyme may contribute to memory impairment in Alzheimer's patients. A transgenic mouse study found impaired memory in animals lacking the enzyme MMP-9, supporting the idea that its inactivity plays a role in the disease.
Research at Washington University in St. Louis uses fMRI to capture images of specific memories as they are formed within the brain. The study found that increased activity in certain brain structures predicts whether information will be retained or forgotten.
A 51-year-old man with a rare brain disorder, known as 'sagging brain,' was treated at UCSF after initial diagnoses failed to provide relief. Exhaustive neurological scrutiny led to the discovery of a ruptured cyst causing the condition, which was successfully treated through surgery.
Researchers found that even mild forms of Alzheimer's can be distinguished from normal aging-related memory changes. The brains of patients with even mild Alzheimer's were found to have amyloid plaques, indicating early disease onset.
Researchers at University of Toronto uncover how protein Src strengthens synaptic connections, enhancing memory and learning. This discovery could lead to new treatments for chronic pain and epilepsy.
A long-term study found that post-menopausal women who used estrogen replacement therapy performed better on visual memory tests than those who didn't receive treatment. The researchers also found that stable memory performance was maintained by some participants who began ERT during regular visits to the NIA.
Research suggests that fact memory can be preserved despite hippocampal damage, offering new hope for children with memory problems. The study's findings have implications for healthcare professionals and teachers in assessing and educating children with special needs.
Researchers at Stanford University have identified two separate clusters of neurons in the hippocampus involved in encoding and retrieving memories. These findings provide insight into the neural basis of memory and could lead to better treatments for Alzheimer's disease and other neurological disorders.
Researchers found that a low-fat diet had no impact on memory loss in old mice, contrary to earlier studies suggesting a correlation between healthy eating and cognitive preservation. The study's findings add weight to theories suggesting that certain genes or stress hormones may contribute to age-related memory decline.
