Smoking Linked to Increased Brain Lesions and Brain Shrinkage in MS

18.08.2009
People who smoke and have multiple sclerosis (MS) may be at increased risk of brain shrinkage and increased brain lesions related to the disease, according to a study published in the August 18, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology. Smoking has already been linked to an increased risk of developing MS.

Researchers studied 368 people in New York with an average age of 44 who had been diagnosed with MS for an average of 12 years. Participants underwent brain scans and were asked about their smoking history.

Of the group, 240 were non-smokers, 96 were current smokers and 32 were past smokers. Current smokers were considered people who smoked more than 10 cigarettes per day in the three months leading up to the study and past smokers were those who smoked for at least six months sometime before the start of the study. The average current smoker in the study had been smoking for 18 years.

The study found that smokers with MS had a greater breakdown of the barrier between the brain and blood and had nearly 17 percent more brain lesions on their scans compared to non-smokers with MS. Smokers with MS had 13 percent larger ventricles and a smaller brain size compared to non-smokers with MS.

“These results show that smoking appears to quite literally injure the brain in a person with multiple sclerosis and increases the risk of disease severity and progression,” said study author Robert Zivadinov, MD, PhD, Associate Professor with State University of New York School of Medicine and Biomedical Sciences in Buffalo. Zivadinov is also the Director of the Buffalo Neuroimaging Analysis Center, the Jacobs Neurological Institute and a member of the American Academy of Neurology. “Our study stresses the importance of anti-smoking education in schools, where many smokers start, and more targeted programs to help people with MS to quit smoking so they can have a better quality of life.”

The study also found that smokers were likely to have more problems with motor functioning, such as walking and taking part in daily activities, than non-smokers.

The study was supported by the National Multiple Sclerosis Society.

The American Academy of Neurology, an association of more than 21,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Parkinson’s disease, ALS (Lou Gehrig’s disease), dementia, West Nile virus, and ataxia.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
