Mechanism explains how seizures may lead to memory loss

Mechanism explains how seizures may lead to memory loss

Although it’s been clear that seizures are linked to memory loss and other cognitive deficits in patients with Alzheimer’s disease, how this happens has been puzzling. In a study published in the journal Nature Medicine, a team of researchers reveals a mechanism that can explain how even relatively infrequent seizures can lead to long-lasting cognitive […]

Studies of epilepsy patients uncover clues to how the brain remembers

In a pair of studies, scientists at the National Institutes of Health explored how the human brain stores and retrieves memories. One study suggests that the brain etches each memory into unique firing patterns of individual neurons. Meanwhile, the second study The studies were led by Kareem Zaghloul, M.D., Ph.D., a neurosurgeon-researcher at the NIH’s […]

‘Silent Seizures’ Discovered in Patients with Alzheimer’s Disease

‘Silent Seizures’ Discovered in Patients with Alzheimer’s Disease

AlDeep in the brains of two patients with Alzheimer’s disease, the main memory structure, the hippocampus, displays episodic seizure-like electrical activity. These non-convulsive hippocampal seizures are the first signs of ‘silent’ brain electrical network dysfunction described in patients with Alzheimer’s disease. The discovery, published in the journal Nature Medicine, provides a better understanding of the […]

Could a Zap to the Brain Jog Failing Memory?

Could a Zap to the Brain Jog Failing Memory?

Deep brain stimulation appears to help, but much more research is needed, scientists say! Can a slight charge of electricity improve an ailing memory? Maybe, according to new research from the University of Pennsylvania.
