Stroke may be triggered by anger, emotional upset and heavy physical exertion
on December 2, 2021 at 7:15 pm
A global study into causes of stroke has found that one in 11 survivors experienced a period of anger or upset in the one hour leading up to it. One in 20 patients had engaged in heavy physical exertion. The suspected triggers have been identified as part of the global INTERSTROKE study, which analyzed 13,462 cases of acute stroke, involving patients with a range of ethnic backgrounds in 32 countries.

Unlocking the cause of UTI-induced delirium
on December 2, 2021 at 7:15 pm
Researchers have found that blocking the action of a protein called interleukin 6 (IL-6), part of the immune system, could resolve the delirium that often accompanies urinary tract infection (UTI) in elderly patients. Their study could pave the way for clinical trials of IL-6 inhibitors as a treatment for UTI-associated delirium in humans. […]

Magnetic resonance imaging (MRI) and artificial intelligence (AI) can detect early signs of tumor cell death after novel therapy
on December 1, 2021 at 8:01 pm
A recent study demonstrates that magnetic resonance imaging (MRI) and artificial intelligence (AI) can be used to detect early signs of tumor cell death in response to a novel virus-based cancer therapy. […]

New way of identifying early risk of cardiovascular disease
on December 1, 2021 at 7:53 pm
The risk of developing cardiovascular disease is strongly associated with 'bad' LDL cholesterol. A large study now shows that two proteins that transport cholesterol particles in the blood provide early and reliable risk information. The researchers now advocate introducing new guidelines for detecting cardiac risk and say the results may pave the way for early treatment, which could help lower morbidity and fatality rates. […]

Targeting the brain’s immune cells may help prevent or treat Alzheimer’s disease
on December 1, 2021 at 7:53 pm
A gene mutation linked to Alzheimer's disease alters a signaling pathway in certain immune cells of individuals with the disease, according to a new study. The team also found that blocking the pathway -- with a drug that's currently being tested in cancer clinical trials -- protects against many features of the condition in a preclinical model. The results could lead to new strategies to block the development of Alzheimer's disease or slow its progression. […]

Coffee and tea drinking may be associated with reduced rates of stroke and dementia
on November 16, 2021 at 7:48 pm
Drinking coffee or tea may be associated with a lower risk of stroke and dementia, according to a new study. Drinking coffee was also associated with a lower risk of post-stroke dementia. […]

Vascular defects appear to underlie the progression of Parkinson's disease
on November 13, 2021 at 12:22 pm
In an unexpected discovery, researchers have identified what appears to be a significant vascular defect in patients with moderately severe Parkinson's disease. The finding could help explain an earlier outcome of the same study, in which the drug nilotinib was able to halt motor and non-motor (cognition and quality of life) decline in the long term. […]

Multiple sclerosis drug improves memory in mice modeling Alzheimer’s disease
on November 5, 2021 at 7:05 pm
Researchers found that glatiramer acetate, a prescription drug currently used to treat patients with multiple sclerosis, improved memory in a mouse model of Alzheimer's disease. […]

Study of 18000+ US and Australian older people reveals moderate drinking protective against heart disease, more than for tea totalers
on November 5, 2021 at 2:37 pm
A landmark study of more than 18,000 Americans and Australians over 70 years of age reveals that 3.5 to 7 average drinks of alcohol a week is more protective against heart disease and in fact all-cause mortality - compared to those who drank no alcohol. […]

Researchers have succeeded in identifying the proteins in the coronavirus that can damage blood vessels
on November 3, 2021 at 2:50 pm
Researchers have identified 5 of the 29 proteins that make up the SARS-CoV-2 virus that are responsible for damaging blood vessels. The researchers hope that the identification of these proteins will help develop targeted drugs for COVID-19 that reduce vascular damage. […]

Death rate from Parkinson's rising in U.S., study finds
on October 28, 2021 at 1:19 am
A new study shows that in the last two decades the death rate from Parkinson's disease has risen about 63 percent in the United States. The study also found that the death rate was twice as high in men as in women, and there was a higher death rate in white people than other racial/ethnic groups. […]

Cat’s meow: Robotic pet boosts mood, behavior and cognition in adults with dementia
on October 27, 2021 at 4:20 pm
Researchers tested the effectiveness of affordable, interactive robotic pet cats to improve mood, behavior and cognition in older adults with mild to moderate dementia. Mood and behavioral symptoms were measured along with cognition using the Mini Mental State Examination (MMSE). Intervention with this robotic cat improved all mood scores over time, with significant improvements in mood and depression. More than half of the participants scored higher on the MMSE post-test than pretest, with slight to moderate improvement in attention/calculation, language, and registration. The robotic cats also provided participants with an alternative way to express themselves. […]

Potential new therapy for inflammatory arthritis
on October 20, 2021 at 7:03 pm
Researchers have made a discovery that could lead to new treatments for axial spondyloarthritis (SpA), a painful and debilitating form of arthritis which causes inflammation in the spine, joints, eyes, gut and skin. […]
