Vitamin D Twice a Day May Keep Vertigo Away

Vitamin D Twice a Day May Keep Vertigo Away - استفاده از ویتامین دی جهت درمان سرگیجه
Taking vitamin D and calcium twice a day may reduce your chances of getting vertigo again, according to a study published in the August 5, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. “Our study suggests that for people with benign paroxysmal positional vertigo, taking a supplement of vitamin D and calcium is a simple, low-risk way to prevent vertigo from recurring,” said Ji-Soo Kim, M.D., Ph.D., of Seoul National University College of Medicine in Korea. “It is especially effective if you have low vitamin D levels to begin with.” Benign paroxysmal positional vertigo happens when a change in head position gives you a sudden spinning sensation. It’s one of the most common types of vertigo. Treatment includes a doctor performing a series of head movements that shift particles in the ears that cause the vertigo, but the condition tends to recur frequently. About 86% of people with this form of vertigo find that it interrupts their daily life or causes them to miss days at work.

Blood test could diagnose baby brain damage just hours after birth

Blood test could diagnose baby brain damage just hours after birth - آزمایش خون جدید می تواند آسیب های مغزی نوزاد را در اولین ساعات تولد تشخیص دهد

An early blood test could detect which babies deprived of oxygen at birth are at risk of serious neurodisabilities like cerebral palsy and epilepsy.

The prototype test looks for certain genes being switched on and off that are linked to long-term neurological issues. Further investigations of these genes may provide new targets for treating the brain damage before it becomes permanent.

The team behind the test, led by Imperial College London researchers in collaboration with groups in India, Italy and the USA, have published their findings today in the journal Scientific Reports.

Physical stress on the job with brain and memory decline in older age

Physical stress on the job with brain and memory decline in older age - مشاغل پرفشار می توانند باعث صدمه مغزی و کاهش حافظه در دوران سالمندی گردند

A new study out of Colorado State University has found that physical stress in one’s job may be associated with faster brain aging and poorer memory.

Aga Burzynska, an assistant professor in the Department of Human Development and Family Studies, and her research team connected occupational survey responses with brain-imaging data from 99 cognitively normal older adults, age 60 to 79. They found that those who reported high levels of physical stress in their most recent job had smaller volumes in the hippocampus and performed poorer on memory tasks. The hippocampus is the part of the brain that is critical for memory and is affected in both normal aging and in dementia.

Their findings were published this summer in Frontiers in Human Neuroscience under the research topic “Work and Brain Health Across the Lifespan.”

“We know that stress can accelerate physical aging and is the risk factor for many chronic illnesses,” Burzynska said. “But this is the first evidence that occupational stress can accelerate brain and cognitive aging.”

Flu, Pneumonia Vaccinations Tied to Lower Risk of Alzheimer’s Dementia

Flu Vaccinations Tied to Lower Risk of Alzheimer Dementia - واکسن آنفولانزا خطر ابتلا به بیماری آلزایمر را کاهش می دهد

Three research studies reported at AAIC 2020 suggest:

  • At least one flu vaccination was associated with a 17% reduction in Alzheimer’s incidence. More frequent flu vaccination was associated with another 13% reduction in Alzheimer’s incidence.
  • Vaccination against pneumonia between ages 65 and 75 reduced Alzheimer’s risk by up to 40% depending on individual genes.
  • Individuals with dementia have a higher risk of dying (6-fold) after infections than those without dementia (3-fold).

“With the COVID-19 pandemic, vaccines are at the forefront of public health discussions. It is important to explore their benefit in not only protecting against viral or bacterial infection but also improving long-term health outcomes,” said Maria C. Carrillo, Ph.D., Alzheimer’s Association chief science officer.

“It may turn out to be as simple as if you’re taking care of your health in this way — getting vaccinated — you’re also taking care of yourself in other ways, and these things add up to lower risk of Alzheimer’s and other dementias,” Carrillo said. “This research, while early, calls for further studies in large, diverse clinical trials to inform whether vaccinations as a public health strategy decrease our risk for developing dementia as we age.”

Gut microbiome influences ALS outcomes

Gut microbiome and ALS - میکروب های روده

Harvard University scientists have identified a new gut-brain connection in the neurodegenerative disease amyotrophic lateral sclerosis, or ALS. The researchers found that in mice with a common ALS genetic mutation, changing the gut microbiome using antibiotics or fecal transplants could prevent or improve disease symptoms.

Patient’s own cells to treat Parkinson’s disease

cells to treat Parkinson - درمان پارکینسون با سلول های پوست

Reprogramming a patient’s own skin cells to replace cells in the brain that are progressively lost during Parkinson’s disease (PD) has been shown to be technically feasible, reports a team of investigators from McLean Hospital and Massachusetts General Hospital (MGH) in the most recent issue of the New England Journal of Medicine.
