We know that migraine, above all in its variation with aura, is associated with negative cardiovascular effects and with an increase in ischemic stroke. It is not clear, instead, the relation existing between this disease and hemorrhagic stroke, so, using data from WHI (Women's Health Study), this relation has been examined. Out of about 28,000 women over 45 years of age and with no history of stroke, 5130 subjects (18%) with a history of migraine have been identified: out of these, 3612 have referred to suffer still from migraine, with a prevalence of about 40% for migraine with aura.

Neuroscientists at the Johns Hopkins University School of Medicine have discovered how the sense of touch is wired in the skin and nervous system. The new findings, published Dec. 22 in Cell, open new doors for understanding how the brain collects and processes information from hairy skin.

Resting-state functional magnetic resonance imaging (fMRI) is emerging as an interesting biomarker for measuring connectivity of the brain in patients with Alzheimer's disease (AD). A review discusses the origins of resting-state fMRI, common methodologies used to extract information from these four-dimensional fMRI scans, and important considerations for the analysis of these scans. Then we present the current state of knowledge in this area by summarizing various AD resting-state fMRI studies presented in the first section and end with a discussion of future developments and open questions in the field.

According to available data, migraine with aura represents a risk factor for cardiovascular diseases, so some researchers in Iceland wanted to verify not only the association between migraine and cardiovascular mortality, but also which relation exists between this disease and overall mortality. About 19,000 adults (averagely 53 years of age at the enrolment into the trial) have been examined for a 26-year follow-up.

Scientists in Canada have raised a tantalising prospect - reversing Alzheimer's disease. They used a technique known as deep brain stimulation - applying electricity directly to regions of the brain. In two patients, the brain's memory hub reversed its expected decline and actually grew.

In the cases where it is not possible to explain the occurrence of a rapid and progressive cognitive decline through usual non-invasive examinations, the use of cerebral biopsy has been proposed. In a trial performed by Emory University in Atlanta, some neurosurgeons have re-examined the medical records of 51 adults undergoing cerebral biopsy between 1999 and 2008 to determine the causes of an acute or sub-acute cognitive decline.

Researchers from Sweden have uncovered an association between shift work and increased risk of multiple sclerosis (MS). Those who engage in off-hour employment before the age of 20 may be at risk for MS due to a disruption in their circadian rhythm and sleep pattern. Findings of this novel study appear today in Annals of Neurology.

Alzheimer’s disease is characterized by the overproduction of plaques formed by beta-amyloid, which can be contrasted through the use of proteins belonging to the family of alpha-secretase. In a trial performed by MIT, some rats with an overproduction of beta-amyloid (with consequent behavioural and cognitive alterations very similar to the ones in Alzheimer’s disease) have been matched with some rats with an overproduction of SIRT1 (a molecule stimulating the production of alpha-secretase and slowing oxidative processes and ageing).

Patients with mild cognitive impairment are at an increased risk of progression to Alzheimer's disease. However, not all patients with mild cognitive impairment progress, and it is difficult to accurately identify those patients who are in the prodromal stage of Alzheimer's disease. Koivunen and colleagues report that Pittsburgh compound-B, an amyloid-beta positron emission tomography ligand, predicts the progression of patients with mild cognitive impairment to Alzheimer's disease.
