Researchers reveal common synaptic pathway behind Parkinson’s and Alzheimer’s diseases

Parkinson's and Alzheimer's diseases are the two most common neurodegenerative disorders, affecting millions of people worldwide.

Survival patterns differ across types of early-onset dementia

The survival rates of people with early onset dementia-diagnosed before the age of 65-vary considerably by clinical type, but sex, age, family history and co-existing conditions aren't specific risk factors, finds research published online in the Journal of Neurology Neurosurgery & Psychiatry.

Free radicals generated at a specific site in astrocytes may promote dementia

Researchers have discovered that free radicals generated at a specific site in non-neuronal brain cells called astrocytes, may promote dementia, according to a Weill Cornell Medicine study.

Small increases in daily steps may slow Alzheimer’s progression

Increasing your steps by even a little bit may help slow down the progression of Alzheimer's disease among people at heightened risk, according to a new study.

Johns Hopkins study reveals enzyme that shields neurons from oxidative stress

New research from Johns Hopkins Medicine shows that the enzyme biliverdin reductase A (BVRA) plays a direct protective role against oxidative stress in neurons, independent of its role producing the yellow pigment bilirubin.

Evidence of previously unrecognized hub in the brain's lymphatic drainage system revealed

How does the brain take out its trash? That is the job of the brain's lymphatic drainage system, and efforts to understand how it works have pushed the boundaries of brain-imaging technologies.

Study reveals how TDP-43 causes neuronal overactivity in ALS and FTD

A new Northwestern University study using patient nervous tissue and lab-grown human neurons has uncovered how a key disease protein, TDP-43, drives overactive nerve cells in the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

Study finds more commonalities between CTE and Alzheimer's disease at the genetic level

Chronic traumatic encephalopathy (CTE) – most often found in athletes playing contact sports – is known to share similarities with Alzheimer's disease (AD), namely the buildup of a protein called tau in the brain.

New method yields up to twice as many therapeutic myogenic cells as previous protocols

If cancer is a disease of overabundance, where cells divide without restraint and tumors grow despite the body's best interests, then degenerative diseases are disorders of deprivation.

How early diabetes management influences long-term outcomes

Could slightly elevated blood sugar levels lead to serious health problems in the future? A single patient's question sparked nearly a decade of research leading to the development of a landmark model that could shape how clinicians and researchers understand and manage diabetes across the US.

Study links short-term blood pressure variability to Alzheimer's-related brain loss

Even when blood pressure is well controlled, older adults whose blood pressure fluctuates widely from one heartbeat to the next may be at greater risk for brain shrinkage and nerve cell injury, according to a new study led by the USC Leonard Davis School of Gerontology.

Unlocking the secrets of NMDA receptors for better brain health

As information zings from cell to cell inside the brain, bursts of electricity spur its transmission. At Cold Spring Harbor Laboratory (CSHL), scientists have turned their attention to the tiny pores that let charged ions enter a cell-and the molecular gatekeepers that help control them.
