"If this protein is removed from the brain," says one of the researchers, "it may cause an impairment of neuronal function, as well as a further and faster accumulation of amyloid-beta in Alzheimer's."

With ketamine use increasing faster than any other drug in the UK, this research showing the consequences of repeated ketamine use provides valuable information for users and addiction professionals alike. Heavy ketamine users were impaired on several measures, including verbal memory.

The 25 sounds were reminders of earlier spatial learning, though the research participants were unaware of the sounds as they slept. Yet, upon waking, memory tests showed that spatial memories had changed. Deep sleep, then, is actually is a key time for memory processing, the study suggests.

But as they age, these kids fall behind. Memory deficits inherent in Down syndrome hinder learning, making it hard for the brain to collect experiences needed for normal cognitive development. Scientists have now demonstrated a possible new approach to slowing the inevitable progression of cognitive decline found in Down syndrome.

A new article provides some of the first evidence in mice and rats that new neurons sprouted in the hippocampus cause the decay of short-term fear memories in that brain region, without an overall memory loss.

Study results show that while preventative brain radiation for patients with nonsmall cell lung cancer -- the most common form of lung cancer -- does reduce the chance of developing brain metastases, it impacts some short-term and long-term memory.

But it hasn't been clear whether people with Alzheimer's disease and diabetes have more rapid memory loss than those who have Alzheimer's disease but no diabetes.

Just as important, the team believes that the cognitive deficits caused by sleep deprivation, such as an inability to focus, learn or memorize, may be reversible by reducing the concentration of a specific enzyme that builds up in the hippocampus of the brain.

In a minority of Alzheimer's patients the disease shows up first as problems with vision rather than memory or other cognitive functions. But diagnosis can be difficult because standard eye exams are often inconclusive for these patients.

Researchers are breaking new ground in biotechnology to find new tools that can help provide new solutions. A newly constructed protein has yielded experimental results that are promising when it comes to stopping the disease.
