Laser therapy could help people with short-term memory problems
Transcranial photobiomodulation applied to the right prefrontal cortex of the brain was found to improve working or short-term memory by 10% several minutes after treatment, as per a study. The changes in the brain due to this treatment were trackable with an EEG. However, why this treatment produced positive results and how long these effects would last is yet to be known.

Exercise may protect against cognitive decline among older people
A study that tested the effects of exercises on cognitive function revealed that people who did high or low-intensity exercises for 12 months had no decline in cognitive function. Also, there were no differences in the effects of high or low-intensity exercises on the ADAS-Cog scores. This trial is believed to be the longest trial on the effects of exercise on cognition.
Elon Musk's Neuralink is under investigation for violations
Internal staff complaints of animal-welfare violations leading to needless suffering and deaths have caused federal investigation, according to sources. The employees also complained that the rush to develop products led to botched experiments. The firm is developing brain implants that target paralyzed people and those with neurological diseases.
A simple urine test could diagnose Alzheimer's disease
A study proposed a urine test to detect AD based on formic acid levels. Formaldehyde plays a role in memory and learning, and high levels of formaldehyde could cause cognitive deficits. Formic acid, a metabolic product of formaldehyde, was found in low levels in people with healthy brains. Formic acid combined with other biomarkers increased AD diagnosis accuracy.
Experts propose a framework to distinguish types of multiple sclerosis
The new framework aims at moving away from clinical descriptions of the disease like primary progressive, secondary progressive, or relapsing-remitting MS. Experts proposed providing more personalized treatment approaches for individuals' disease courses as MS is affected and driven by mechanisms of nervous system injury and how well a person's body counterbalances it.

Biomarker for primary tauopathies identified
Tauopathies refer to rare brain diseases characterized by rapidly worsening issues with movement and thinking. They are not easy to distinguish from other brain diseases due to similar symptoms. Researchers now found a biomarker for a tauopathy called corticobasal degeneration. Microtubule binding region (MTBR)-tau 275 and MTBR-tau 282 were 89% accurate, as per a study.
Obesity in children could cause structural changes in the brain
Children aged 9 and 10 years who had the highest BMI scores also had brain impairment, including thinning of the cortex and degradation of white matter, as per a study. These impairments could affect kids' motivation, reward-based decision-making, and even cognitive control. These findings highlight that a healthy lifestyle in childhood promotes healthy brains.
New dementia drug raises the risk of brain swelling
Lecanemab, which was hailed as the breakthrough in dementia research, drastically slowed the disease progression, but 1 in 10 patients suffered brain swelling, and 1 in 6 had brain bleeds in clinical trials, as per s study. A small proportion of participants also experienced dizziness and headaches. These side effects could block NHS from rolling out the drug safely.

Guidance on communicating sensitive information to multiple sclerosis patients
The new guidance minimises apprehension and misunderstanding about brain atrophy, which could devastate patients. Brain atrophy or reduction in the brain volume measured by MRI can predict the progression of disability. Doctors should convince patients to adhere to treatment protocols and explain brain atrophy compared with the brain's normal ageing.
Which form of exercise is most effective in reducing migraine?
A meta-analysis and systematic review showed that strength training could be the most effective exercise to reduce the migraine burden. It is followed by high-intensity aerobic exercise and moderate-intensity aerobic exercise. Strength training's benefits could be due to muscle strengthening of significant muscles in the shoulder and neck regions, which can trigger pain.
