Difference in the structure of the brain blood vessels may cause migraine

Migraine is a cause of significant disability in people around the world and various theories have been postulated to explain it. While earlier it was believed that migraine was caused due to abnormal dilatation of the cerebral blood vessels, later it was thought that migraine was a result of abnormal neuronal activity in the brain. However, a new study published in the latest issue of the journal PLoS One has found that a difference in the structure of the blood vessels supplying the brain...

ACE inhibitors may benefit dementia patients

Centrally acting ACE inhibitors have been found to be associated with a reduced rate of cognitive decline. Moreover, they have been seen to actually improve the cognitive functions in the initial six months of their use. These are the findings of a new study carried out by William Molloy from the Centre for Gerontology and Rehabilitation at the University College Cork, St. Finbarrs' Hospital, Ireland, along with his colleagues, and published in the latest issue of the online journal BMJ Open...

Exposure to pesticides increases the risk of Parkinson's disease

A new study published in the journal Neurology tried to find out whether there is any association between exposure to pesticides and solvents, and Parkinson’s disease. Although the researchers, led by Dr. Emanuele Cereda from the IRCCS University Hospital San Matteo Foundation at Pavia and Gianni Pezzoli from the Parkinson Institute, Milan, Italy, could not prove that pesticides are directly responsible for causing the disease, they found that exposure to pesticides and solvents increases the...

Thalamic atrophy can be used as a biomarker for multiple sclerosis

the multiple sclerosis
Many patients experience clinically isolated syndrome (CIS) of multiple sclerosis and a few of them suffer from subsequent attacks and go on to develop clinically definitive multiple sclerosis (CDMS). However, it is difficult to predict the risk of CDMS in patients with CIS. Now, in a study published in the journal Radiology, researchers have found that progression to multiple sclerosis is associated with atrophy of the thalamic region and increase in the volume of the lateral ventricle of the...

Brain Insulin Resistance and Toxic Ceramide Production linked to Progression of Alzheimer’s disease

A recent study published in the Journal of Alzheimer’s disease has found that the insulin resistance shown by the brain, along with brain stress and production of toxic ceramide is linked to the progression of Alzheimer’s disease. The study, which was led by Suzanne de la Monte, a researcher at the Rhode Island Hospital, found that there are two key mediators of neuronal injury, which couple with diabetes to help in the propagation of the disease. Alzheimer’s disease is one of the leading...
