Health Day: Radiation for childhood brain tumor can hinder memory

Radiation therapy for the most common childhood brain tumor can cause memory problems, new research suggests. Specifically, it can leave young survivors struggling to create memories of recent personal events, the small study found. But survivors’ ability to recall ones that happened before radiation wasn’t affected. (August 21, 2018) Read the full article here

Medical Xpress: Alzheimer’s linked to the brain’s ‘garbage disposal service’

Researchers in South Australia have found a genetic link between Alzheimer’s disease and the endo-lysosomal system, a critical part of biological recycling machinery that maintains the health of brain cells. The researchers from the South Australian Health and Medical Research Institute (SAHMRI) say the findings give them a reason to focus on the endo-lysosomal system […]

New Atlas: Restoring brain plasticity may hold key to reversing age-related cognitive decline

Normal aging is commonly associated with a variety of mild sensory and cognitive declines. Separate to any acute dementia-related disease, this average age-related brain decline has been commonly thought to be caused by a slow reduction in the total number of brain cells. However, a new study from MIT’s Picower Institute for Learning and Memory […]

Medical Xpress: Rogue proteins may underlie some ALS and frontotemporal dementia cases, says study

ALS—amyotrophic lateral sclerosis—is a neurodegenerative disease that attacks motor neurons in the brain and spinal cord, slowly robbing its victims of their ability to walk, talk, breathe and swallow. In a cruel twist, some ALS patients also develop frontotemporal dementia, a disease that destroys an entirely different set of brain cells—cortical neurons—leading to personality changes, […]

Medical News Today: Multiple sclerosis: Healthful diet tied to lower risk

Eating a healthful diet that is rich in vegetables, fish, legumes, eggs, and poultry is tied to a lower risk of multiple sclerosis, a long-term disease that affects the brain, spinal cord, and optic nerve in the eyes. This was the conclusion that researchers from Australia came to after studying links between diet and central […]

Medical Xpress: Letting PTSD patients choose method of treatment improves their health, quality of life: new research

Letting people with post-traumatic stress disorder (PTSD) choose between treatment methods improves their quality of life and reduces the disorder’s symptoms, according to new research from Case Western Reserve University. The same data also showed that patients with PTSD using marijuana or other drugs saw poorer outcomes from treatment, mainly because they dropped out of […]

Phys.org: Study tracks inner workings of the brain with new biosensor

An international team of scientists have taken an important step towards gaining a better understanding of the brain’s inner workings, including the molecular processes that could play a role in neurological disorders. The research team has used a new biosensor to optically track the movements of the neurotransmitter glycine – a signalling molecule in the […]

Science Daily: First biomarker evidence of DDT-autism link

A study of more than 1 million pregnancies in Finland reports that elevated levels of a metabolite of the banned insecticide DDT in the blood of pregnant women are linked to increased risk for autism in the offspring. An international research team led by investigators at Columbia University’s Mailman School of Public Health and the […]

News-Medical: Maternal stress increases anxious and depressive-like behaviors in female offspring

High maternal levels of the stress hormone cortisol during pregnancy increase anxious and depressive-like behaviors in female offspring at the age of 2, reports a new study in Biological Psychiatry. The effect of elevated maternal cortisol on the negative offspring behavior appeared to result from patterns of stronger communication between brain regions important for sensory […]
