The Claim
Elevated theta power in the occipital cortex, as measured by magnetoencephalography, is associated with an increased likelihood of progression from mild cognitive impairment (MCI) to Alzheimer's disease within a two-year period.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with mild memory problems who have stronger theta brain waves in the back of the brain have a higher chance of progressing to Alzheimer's disease within two years.
See the scientific wording
Increased occipital cortex theta power, measured by magnetoencephalography, is associated with a higher likelihood of progression from mild cognitive impairment to Alzheimer's disease within 2 years.
In the back part of the brain that processes vision, brain cells become damaged because proteins build up inside them. Damage causes these cells to send slower and weaker signals, which shows up as slower brain waves. This damage spread to other brain areas, making memory and thinking problems worse, so that within two years a person with mild cognitive impairment moves to full Alzheimer's disease.
What the research says
1 studyThe study found that brain wave activity in the back of the brain helped predict who would develop Alzheimer's within two years, so higher levels of that wave are linked to a greater chance of progression.
