    No one's brain is as sharp at 60 as it was at 20.

    However, new research supports the notion that folk's brains can make subtle adjustments with age to compensate for that decline.

    A team of British researchers has found more evidence that as the mind ages, it sometimes recruits help from certain brain regions to make up for deficits elsewhere.

    This does not happen for everyone...

    Scientists say they've created the first 3D-printed brain tissue where neurons network and "talk" to each other.

    Five of eight British children who received human growth hormone from the pituitary glands of deceased donors went on to develop early-onset Alzheimer's disease many decades later, researchers report.

    Researchers at University College London (UCL) suspect that the growth hormone received by these people in childhood may have contained amyloid-beta protein plaques, which build up in the br...

    'Young folk don't write in cursive anymore' is a common complaint of older folks in this keyboard-obsessed age.

    Now, new research suggests that kids who ignore handwriting are, in fact, missing out: By the time they reach college, their brain "connectivity" may be weaker than folks who write regularly.

    In a study of 36 university students, "we show that when writing by hand, brain c...

    Strange visual disturbances occur early in about 10% of Alzheimer's cases, and when this happens it almost always signals the impending arrival of the disease, a new study finds.

    The fluid-filled spaces around the brain's blood vessels need proper waste "clearance" every few hours. When that fails to happen, a baby's risk for autism appears to rise, new research shows.

    It's too early to say that trouble within these "perivascular" spaces causes autism, but it seems to be an early marker for the condition, a team from the University of North Carolina (UNC) reports....

    From alcohol use to social isolation, poor hearing and heart disease, researchers have identified more than a dozen non-genetic factors that up the risk of dementia for people under 65.

    Though about 370,000 new cases a year of young-onset dementia are diagnosed worldwide, it hasn't been well-researched.

    Now, a large study from scientists in the U.K. and the Netherlands suggests that...

    A new cellular therapy improved learning and memory in mice with Alzheimer's disease, researchers report.

    The therapy -- developed at the University of Nebraska Medical Center (UNMC) -- relies on both the immune system to fight key aspects of Alzheimer's, plus modified cells that zero in on the brain protein plaques that are a hallmark of the disease.

    In patients with Alzheimer's, a...

    Stroke patients often suffer from "spatial neglect" -- an inability to see things on the side of the body opposite to where the brain injury occurred.

    Now, new research suggests that spatial neglect can also affect folks who've had a traumatic brain injury (TBI).

    Are you necessarily at higher risk of Alzheimer's disease just because you're 80, and not 75? New research shows it's more complex than that.

    The findings suggest that it's the pace of buildup in the brain of Alzheimer's-linked amyloid protein plaques that matters most, not age.

    “Our findings are consistent with studies showing that the amyloid accumulation in the brain takes deca...

    Head injuries related to football might be tied to markers of dementia like brain shrinkage and decreased blood flow to the brain, a new study of former pro and college players reports.

    These are caused by red...

    Early research in mice could be getting closer to the roots of what causes Parkinson's disease.

    A "pathological" form of a common brain protein, alpha-synuclein, could play a role in the death of dopamine-rich brain cells, according to a team at Johns Hopkins School of Medicine in Baltimore.

    It's this steady loss of dopamine cells that's a hallmark of Parkinson's, researchers explai...

    Smoking shrinks the human brain, and once that brain mass is lost then it's gone for good, a new study warns.

    Brain scans from more than 32,000 people strongly link a history of smoking with a gradual loss of brain volume. In fact, the more packs a person smoked per day, the smaller their brain volume, researchers found.

    The study also establishes the potential series of events that...

    A study involving twins suggests that if you have a sibling who develops dementia, that might not bode well for your life span.

    That's true even if you don't go on to develop dementia yourself, according to a study from U.S. and Swedish researchers.

    One investigator was surprised by the finding.

    “We expected a different result. We expected that, in twins where one developed ...

    Games like football, soccer and rugby come to mind when thinking about sports-related concussions.

    But a smashing tennis shot could cause a traumatic brain injury if the ball whacks a player's head, a new study argues.
