<div style="font-family:Helvetica, sans-serif; text-align:left;color:#999;font-size:11px;font-weight:bold;line-height:15px;">Jun 30th 2025, 10:04</div>
<div style="font-family:Helvetica, sans-serif; color:#494949;text-align:justify;font-size:13px;">
<p>Scientists have uncovered a surprising sugar-related mechanism inside brain cells that could transform how we fight Alzheimer’s and other dementias. It turns out neurons don’t just store sugar for fuel—they reroute it to power antioxidant defenses, but only if an enzyme called GlyP is active. When this sugar-clearing system is blocked, toxic tau protein builds up and accelerates brain degeneration.</p>

<div style="font-family:Helvetica, sans-serif; text-align:left;color:#999;font-size:11px;font-weight:bold;line-height:15px;">Jun 29th 2025, 05:06</div>
<div style="font-family:Helvetica, sans-serif; color:#494949;text-align:justify;font-size:13px;">
<p>Deleting a gene called PTEN in certain brain cells disrupts the brain’s fear circuitry and triggers anxiety-like behavior in mice — key traits seen in autism. Researchers mapped how this genetic tweak throws off the brain's delicate balance of excitation and inhibition in the amygdala, offering deep insights into how one gene can drive specific ASD symptoms.</p>

<div style="font-family:Helvetica, sans-serif; text-align:left;color:#999;font-size:11px;font-weight:bold;line-height:15px;">Jun 29th 2025, 04:35</div>
<div style="font-family:Helvetica, sans-serif; color:#494949;text-align:justify;font-size:13px;">
<p>Researchers are using an advanced brain imaging method called MEG to understand why Parkinson’s drug levodopa doesn’t work equally well for everyone. By mapping patients’ brain signals before and after taking the drug, they discovered that it sometimes activates the wrong brain regions, dampening its helpful effects. This breakthrough could pave the way for personalized treatment strategies, ensuring patients receive medications that target the right areas of their brain more effectively.</p>

<div style="font-family:Helvetica, sans-serif; color:#494949;text-align:justify;font-size:13px;">
<p>USC researchers have found a promising new brain scan marker that could better detect Alzheimer’s risk — but only for some. The tau-based benchmark works in Hispanic and White populations when paired with another Alzheimer’s protein, amyloid, but falls short for Black participants, revealing critical gaps in current diagnostics.</p>
