New Research Determines How a Single Brain Trauma May Lead to Alzheimer’s Disease

A study, performed in mice and utilizing post-mortem samples of brains from patients with Alzheimer’s disease, found that a single event of a moderate-to-severe traumatic brain injury (TBI) can disrupt proteins that regulate an enzyme associated with Alzheimer’s. The paper, published in The Journal of Neuroscience, identifies the complex mechanisms that result in a rapid and robust post-injury elevation of the enzyme, BACE1, in the brain. These results may lead to the development of a drug treatment that targets this mechanism to slow the progression of Alzheimer’s disease.

Researchers Develop Novel Drug That Reverses Loss of Brain Connections in Models of Alzheimer’s

Researchers have developed an experimental drug, NitroMemantine, to boost brain synapses lost in Alzheimer's disease. The drug stops the destructive cascade of brain changes which destroy connections between neurons that leads to memory loss and cognitive decline.

New Alzheimer’s Research Suggests Possible Cause: The Interaction of Proteins in the Brain

Researchers discover by looking at amyloid-beta and tau independently that the interaction between the proteins could be the key to the cognitive decline associated with Alzheimer's disease. As the interaction between the two proteins increased, the progression of Alzheimer's worsened.
