The Claim
In individuals with mild cognitive impairment or dementia, increased hippocampal spontaneous neural activity, as measured by amplitude of low-frequency fluctuations (ALFF), is positively correlated with worsening cognitive performance on the ADAS-cog scale, suggesting that heightened hippocampal activity may represent a compensatory response to neurodegeneration rather than improved cognitive function.
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.
When people with early memory problems have more random brain activity in the area that handles memory, their memory and thinking skills tend to get worse—not better. This might mean their brain is working extra hard to try to make up for damage, not that it’s getting stronger.

What the research says
1 studyThe study found that when the memory center of the brain becomes more active in people with memory problems, their thinking skills get worse — which means the brain might be working harder to try to make up for damage, not getting better.
