LATE is a brain disorder that causes dementia in older individuals. In fact it is the third most common cause of dementia, but it affects many of the same brain regions as Alzheimer's disease so it presents with similar symptoms, and it's only with the advent of special diagnostic tests that clinicians have realized how common it is.

We all have habits we'd like to break, but the brain doesn't make changes easily. Breaking an unhealthy habit can be done; to do so, it helps to understand what's happening in the brain, know why you want to change, and accept that there will be setbacks along the way.

Growing evidence suggests that several viruses may be triggers of multiple sclerosis, and a long-term study found evidence that an infection with a common virus can be an important contributing factor in MS.

Though decades of research have suggested risk factors for amyotrophic lateral sclerosis, a specific cause remains unknown. New research studied professional football players and found that they had a much higher risk of developing ALS than men in the general population, though the study was only observational.

Although it has been known for some time that individuals with dementia frequently have poor, fragmented sleep, two new studies suggest that if you don't get enough sleep in midlife, you are at increased risk for dementia later in life.

Myasthenia gravis (MG) is a rare neuromuscular disease that impairs the transmission of nerve signals to muscles, causing temporary weakness of affected muscles. While treatment is complex, recently updated guidelines have added to the understanding of MG and are improving approaches to treatment.
