Alzheimer’s Research Offers Hope for Restored Memory Function

Alzheimer’s Research May Offer Hope for Restored Memory Function Lisa F. Young/Fotolia

Researchers in Australia have discovered a new way to use non-invasive ultrasound that may one day restore memory functions previously lost to Alzheimer’s disease.

Ultrasound is a well-known test that allows doctors to see inside your body to get an early peek at a growing baby, or to search for abnormalities in breast tissue.

Alzheimer’s disease is a progressive condition that gradually damages the brain. People with Alzheimer’s slowly lose memories, thinking skills and basic abilities to function in normal life.

Alzheimer’s disease is currently irreversible.

According to the National Institute on Aging, Alzheimer’s disease is the most common type of dementia, with symptoms typically starting after age 60.

Alzheimer’s is the sixth leading cause of death in the United States. An estimated 5 million people in the United States are believed to have the disease. (2)

Alzheimer’s disease damages the brain by destroying neurons. Neurons are nerve cells with many branches. Messages pass from one nerve cell to another by jumping from branch to branch.

Neurotransmitters are chemicals that help messages jump across the gap from one nerve cell to another. (3)

Alzheimer’s disease interferes with both electrical signals inside a brain cell, and with the chemical neurotransmitters that help messages travel between cells.

Scientists believe there are two main components that block the brain’s signals in Alzheimer’s disease. One occurs when pieces of protein clump together, forming beta-amyloid plaques. These plaques can block signals from passing between nerve cells. (3)

A second defect that occurs in Alzheimer’s disease is the development of tangles.

In a healthy brain, parallel channels similar to railroad tracks allow food and other necessary materials to travel to all parts of the brain.

But in Alzheimer’s disease, those tracks become disordered, and form tangles that prevent nutrients from getting to cells. When this happens, the starved cells in the brain die.
