Men with restless legs syndrome (RLS) have a nearly 40% increased risk of death compared to men without RLS. The study also found that the association dropped only slightly after adjusting for factors such as body mass index and lifestyle, indicating that RLS may lead to higher mortality rates independently of other known risk factors.
Research found that people with atrial fibrillation experience lower memory and thinking scores at earlier ages, with faster decline rates compared to those without the condition. Cognitive impairment or dementia risk may be higher for those with atrial fibrillation, particularly after age 75.
The new guideline from the American Academy of Neurology helps people with stroke and atrial fibrillation decide whether to take blood thinners during surgery. For minor procedures, the risk of bleeding is small, but for certain hip and colon procedures, it's higher.

A new study finds that the US is facing a severe neurologist shortage, with a projected need for 11% more doctors to meet current needs by 2025. The demand for neurologists is expected to grow faster than the supply, with average wait times for new and follow-up visits increasing.
Research suggests that fainting, also known as vasovagal syncope, may have a genetic component, with some families affected by multiple genes. Triggers such as emotional distress, pain, and frightening thoughts vary greatly within families, but the study found no link between triggers and genetic inheritance.

The AAN has released an evidence-based guideline for evaluating and managing athletes with suspected concussions. The new guideline emphasizes that any athlete suspected of experiencing a concussion should immediately be removed from play, and recommends concussion and return to play assessments be done individually. Athletes under hig...

This discovery has important implications for the diagnosis and treatment of MS-related cognitive problems.
A new study published in Neurology found no correlation between antioxidant intake and risk of developing stroke or dementia. The study suggests that individual antioxidants and food sources may be more important than total antioxidant levels in reducing the risk of these conditions.
A new study published in Neurology suggests that wearing a nerve stimulator for 20 minutes a day can reduce the frequency of migraine attacks. The device delivers electrical stimulation to the supraorbital nerve, resulting in fewer days with migraine and a significant reduction in attack frequency compared to sham treatment.
A new study projects that Alzheimer's disease cases will increase from 4.7 million in 2010 to 13.8 million in 2050, with 7 million cases expected in people aged 85 or older. The increasing number of dementia cases poses a significant burden on society and highlights the need for more research, treatments, and preventive strategies.
A new study published by the American Academy of Neurology found that obesity may increase the risk of developing multiple sclerosis (MS) in children and teenage girls. The research, which analyzed data from over 913,000 children, found a significant association between obesity and MS in girls, but not in boys.
A recent study found that only 22% of participants who reported certain triggers developed a migraine attack after exposure. The research suggests that people may no longer need to avoid suspected triggers if they don't experience a headache episode within three months.
Two studies found that migraine with aura is a strong contributor to cardiovascular events like heart attack and stroke. Women with this condition are more likely to experience blood clot complications, especially those on newer contraceptives.
A study of 1,837 women found that early surgical menopause is associated with faster declines in long-term memory and overall thinking abilities. Women on hormone replacement therapies had slower declines.
A new study published in Neurology shows that people with early Parkinson's disease often experience non-motor symptoms like anxiety, constipation, and drooling. These symptoms can significantly impact quality of life and are treatable if addressed.
Research shows that individuals with depression after a stroke have a tripled risk of dying early and four times the risk of death from stroke. Screening for and treating depression in stroke survivors may be key to addressing these risks, according to study author Amytis Towfighi.
Researchers have discovered a potential new method for diagnosing Parkinson's disease by testing the saliva gland. The study found that abnormal proteins associated with the disease were consistently present in the submandibular salivary glands of patients, suggesting this non-invasive test could be used to diagnose living individuals.
Researchers found that stem cell transplantation significantly extended the lifespan of mice with ALS by 20 days and improved their neuromuscular function by 15 percent.

A large study of 263,925 adults found that drinking more than four cans of soda per day increased the risk of depression by 30%, compared to those who drank no soda. Conversely, drinking four cups of coffee per day was associated with a 10% lower risk of depression.
A study found that beta blocker medications reduced brain abnormalities associated with Alzheimer's disease and microinfarcts in elderly Japanese-American men. The results suggest that beta blockers may delay or prevent dementia in people with high blood pressure, particularly those taking the medication alone.
Researchers found no correlation between Parkinson's disease itself and impulse control symptoms, contradicting previous studies. The study suggests that dopamine-related medications may be the primary cause of these disorders.

The study found that participants with adult child partners were more likely to be from diverse backgrounds, while those with spouse partners were more likely to be white and older.
A new study published in Neurology found that people who went hungry as children had slower cognitive decline than those who always had enough food to eat. The study involved over 6,000 participants and found a significant association between childhood hunger and reduced cognitive decline.
