Study provides further insight into the molecular control of apoptosis

Researchers at Yale School of Medicine have gained deeper understanding of two members of a family of proteins called caspases that play a key role in promoting apoptosis, a process in which the cell responds to external signals by essentially committing suicide.

Hospitalization of a spouse can harm the wellbeing of his or her partner

In the largest study ever to quantify caregiver burden and the widower effect, researchers found that for people aged 65 and older, hospitalization of a spouse can harm the wellbeing of his or her partner and significantly contribute to that partner's death.

Tetrabenazine cuts down involuntary movements in Huntington's disease

The medication tetrabenazine cut down involuntary movement in patients with Huntington's disease on average by about 25 percent, with many patients experiencing a greater improvement, according to a study in the February 14 issue of the journal Neurology.

Major Alzheimer's discovery

A team from the Faculty of Medicine at Universiti Laval and the research centre at CHUQ (Centre hospitalier universitaire de Quibec) has discovered a natural defence mechanism that the body deploys to combat nerve cell degeneration observed in persons with Alzheimer's disease (AD).

Research suggests that a common mechanism may underlie a variety of protein folding diseases

Misfolded and damaged proteins are common to all human neurodegenerative diseases. Clumps of these aggregated proteins destroy neurons within the brain and cause disease.

Researchers develop way to visualize synchronized interactions of nerve cells in the brain

Researchers at the University of Minnesota Medical School and the Brain Sciences Center at the Minneapolis VA Medical Center have discovered a new way to assess how brain networks act together.

Brain scans may detect neurological decline in normal people

Brain scans may detect neurological changes in people who exhibit no outward signs of cognitive decline but who later develop dementia or mental impairment, according to the results of a new study led by researchers at the University of California, Berkeley.

Research may help explain Alzheimer's memory loss

Based on laboratory research, scientists at Georgetown University Medical Center have a new theory as to why people with Alzheimer's disease have trouble performing even the simplest memory tasks, such as remembering a family member's name.

A high level of education means Alzheimer's hits later, but harder and faster

According to researchers at the Columbia University Medical Center in New York, high levels of education may help ward off Alzheimer’s disease, but they also speed up its progression once the disease has developed.

Risk of Alzheimer's 80% genetic

In the largest twin study to date, researchers in the U.S. looked at the Swedish Twin Registry to see which factors lead to Alzheimer's disease (AD).

NogoReceptor reduces Alzheimer's plaque

Increasing the level of a protein that plays a key role in traumatic spinal cord injuries and multiple sclerosis reduces the concentration of disease-causing plaque in Alzheimer's disease, Yale School of Medicine researchers report in the Journal of Neuroscience.

Alzheimer's disease appears to be highly heritable

In a large study of twins, Alzheimer's disease appears to be highly heritable and genetic factors may also influence timing of the disease, according to an article in the February Archives of General Psychiatry.

Depression linked to Alzheimer's

A lifetime history of depression is associated with increased plaques and tangles in the brains of those with Alzheimer's disease and more rapid cognitive decline, according to a study by researchers at the Alzheimer's Disease Research Center at Mount Sinai School of Medicine.

Alzheimer disease has a genetic cause in up to 80 percent of cases

"Our finding confirms the higher estimates that have been suggested previously. The important thing is that no one has had this large a sample before," Gatz said, adding the size was 10 times that of any previous study.
