Two new studies published in the April 4 online issue of Neurology, the medical journal of the American Academy of Neurology, suggest that a person’s memory declines at a faster rate in the last two-and-a-half years of life than at any other time after memory problems first begin. The second study shows that keeping mentally fit through board games or reading may be the best way to preserve memory during late life. Both studies were conducted by researchers at Rush University Medical Center.

Anxiety boosts sense of smell
Anxious people have a heightened sense of smell when it comes to sniffing out a threat, according to a new study by Elizabeth Krusemark and Wen Li from the University of Wisconsin-Madison in the US. Their work¹ is published online in Springer’s journal Chemosensory Perception. The study is part of a special issue² of this journal on neuroimaging the chemical senses.
Researchers discover drug target for stimulating recovery from stroke
Investigators at the Stanford University School of Medicine have shown that removing a matched set of molecules that typically help to regulate the brain’s capacity for forming and eliminating connections between nerve cells could substantially aid recovery from stroke even days after the event. In experiments with mice, the scientists demonstrated that when these molecules are not present, the mice’s ability to recover from induced strokes improved significantly.
Lifestyle study highlights key differences in relapsing and progressive onset MS
Patients with relapsing onset Multiple Sclerosis (MS) who consumed alcohol, wine, coffee and fish on a regular basis took four to seven years longer to reach the point where they needed a walking aid than people who never consumed them. However the study, published in the April issue of the European Journal of Neurology, did not observe the same patterns in patients with progressive onset MS.
