Prevailing Alzheimer’s Theory in Question With New Discovery

Study finds amyloid-beta plaques may not be the cause of memory loss associated with Alzheimer's disease, but instead a consequence of the disease. Regardless of the levels of amyloid plaques, researchers found individuals with high levels of amyloid peptide were cognitively normal. Higher levels of soluble amyloid beta peptide were also linked to people having a larger hippocampus.

First Glimpse of Brains Retrieving Mistaken Memories Observed

Rat study reveals place cells in the hippocampus have the same patterns of activity whether they correctly, or incorrectly recall a memory. However, when the memory is incorrect, the activity begins later and is slower.

Blood Oxygen Levels Could Explain Why Memory Loss Is an Early Alzheimer’s Symptom

Decreased blood flow and blood oxygen levels to the hippocampus may explain symptoms of memory loss associated with Alzheimer's. Researchers say increasing hippocampal blood flow could reverse or protect against symptoms of the neurodegenerative disorder.

Two Halves of the Hippocampus Have Different Gene Activity

Researchers have identified significant differences in gene activity between the anterior and posterior areas of the hippocampus. Genes associated with depression and other mood disorders are more active in the anterior hippocampus, while genes linked to cognitive disorders, such as ASD, are more active in the posterior hippocampus.

‘Rejuvenating’ the Alzheimer’s Brain

MicroRNA-132 regulates neurogenesis in the hippocampus, according to both mouse and human tissue studies. Restoring levels of microRNA-132 in mouse models of Alzheimer's disease reduces neurogenetic deficits and restores cognitive abilities, researchers say.

Researchers Observe New Complexity of Traveling Brain Waves in Memory Circuits

A new micro-grid recording device allowed researchers to measure hippocampal activity in epileptic patients. They found brain waves travel back and forth across the brain structure, integrating messages from different areas of the brain.
