World-Wide FINGERS (WW-FINGERS) is the first global network of clinical trials for risk reduction and prevention of dementia and Alzheimer´s disease through multidomain interventions. Spanish researchers from the Barcelonaβeta Brain Research Center (BBRC), the Hospital del Mar Medical Research Institute (IMIM) and the CITA Alzheimer Foundation participate in this network which convenes research teams from over 30 countries. The main scope, scientific strategy and activities of the WW-FINGERS network have been recently published in Alzheimer´s & Dementia. WW-FINGERS builds upon the successful experience of FINGER study: the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability, led by Prof. Miia Kivipelto and her team (Karolinska Institutet, Sweden; University of Eastern Finland; Finnish National Institute for Health and Welfare and Imperial College London, UK). This pioneering randomized clinical trial (RCT) demonstrated that a 2-year multidomain lifestyle intervention consisting of nutritional guidance, exercise, social stimulation, cognitive training, and control of vascular risk factors benefitted cognition in seniors at increased risk of dementia (Lancet 2015).

Cannabis use can lead to behavioral changes, including reduced social interactions in some individuals. To better understand the phenomenon, Inserm researcher Giovanni Marsicano and his team from NeuroCenter Magendie (Inserm/Université de Bordeaux), in collaboration with University of Salamanca (Spain) professor, Juan P Bolaños and his team, have identified for the first time in mice the cerebral mechanisms underlying the relationship between cannabis and reduced sociability. Their findings have been published in Nature. Dr. Arnau Busquets, currently a Ramon y Cajal researcher in the IMIM's Integrated Pharmacology and Systems Neuroscience Research Group is one of the first authors of this work. He has been responsible for carrying out the in vivo part of the project in mice, during his postdoctoral period in Dr. Marsicano's team in Bordeaux. Dr. Busquets started his own group last September (https://www.imim.cat/programesrecerca/neurociencies/grfh/cell-type_mechanisms_in_normal_and_pathological_behavior/index.htm)

A team of researchers led by Dr. Victoria Puig from the Hospital del Mar Medical Research Institute (IMIM), which also involved the Centre for Genomic Regulation (CRG), has studied the neural basis of intellectual disability in mice with Down syndrome and has discovered that the neural networks of brain circuits relevant to memory and learning are over-activated and that the connectivity of these circuits is poor. The researchers have also observed that neural activity during sleep is abnormal and probably interferes with memory consolidation. The study has even identified biomarkers in brain rhythms that can predict memory deficits in the mice which are corrected by chronic treatment with a natural component of green tea, epigallocatechin gallate, which other studies have already shown to improve executive function in adults with Down syndrome.

Up to now, it was not known what happened in the human body after maslinic acid and oleanolic acid were consumed in diet-compatible quantities, in other words, what happened from the moment they were ingested until their total elimination from the body, what is referred to as pharmacokinetics. Furthermore, information on the biological activity of these biomolecules in the human body is very scarce in the scientific literature. Using a method for determining oleanolic and maslinic acids in plasma developed by the Integrated Pharmacology and Systems Neuroscience Research Group at the Hospital del Mar Medical Research Institute (IMIM), and the Barcelona Mar Health Park Consortium node of the Physiopathology of Obesity and Nutrition (CIBERobn) network, as part of the NUTRAOLEUM research project, a clinical trial on humans has evaluated the pharmacokinetics of these two triterpenic acids from the olive tree after the ingestion of olive oils enriched in these biomolecules at two different concentrations. In addition, the effect of these triterpenic acids on endothelial function has also been studied, revealing that they contribute to preserving blood vessel health and preventing arteriosclerosis.

Researchers from the UAB and the IMIM published in Scientific Reports the first evidence in a non-human species, the domestic dog, of a relation between joint hypermobility and excitability: dogs with more joint mobility and flexibility tend to have more anxiety problems. The relation between collagen laxity and anxiety in humans is widely known, but this relation has never been observed before in other species. A team of researchers led by professors Jaume Fatjó and Antoni Bulbena from the Department of Psychiatry and Legal Medicine at the UAB, the Hospital del Mar Medical Research Institute (IMIM) and the UAB Affinity Foundation Chair in Animals and Health, analysed a set of 13 animal behaviour characteristics and hip joint mobility in a total of 5575 domestic dogs. The results point to an association between hip joint hypermobility and a brain activation linked to emotions in dogs, with similar results as to those observed in people.

Dr. Rafael de la Torre, director of the Neurosciences research programme at the Hospital del Mar Medical Research Institute (IMIM), is leading a clinical trial involving a paediatric population, the aim of which is to evaluate the safety and effectiveness of a dietary preparation containing epigallocatechin gallate (EGCG) – a natural compound found in green tea- on improved cognitive development in children, aged 6 to 12, with Down's syndrome, and which will also evaluate its effect on children with Fragile X syndrome. The paediatric clinical trials will take place simultaneously in 5 health centres: Hospital Niño Jesús (Madrid), Instituto Hispalense de Pediatria (Seville), Hospital Universitario Marqués de Valdecilla (Santander), Hospital del Mar ( Barcelona), and Institut Jérome Lejeune (Paris).

A study directed by researchers from the UAB and IMIM are the first to reveal how pregnancy causes long-lasting alterations in brain structure, probably related to improving the mother’s ability to protect and interact with the child. The research was published in Nature Neuroscience. Pregnancy involves radical hormone surges and biological adaptations, but the effects on the brain are still unknown. In this study a team of researchers compared the structure of the brain of women before and after their first pregnancy. This is the first research to show that pregnancy involves long-lasting changes – at least for two years post-partum – in the morphology of a woman's brain. Using magnetic resonance imaging, the scientists have been able to show that the brains of women who have undergone a first pregnancy present significant reductions in grey matter in regions associated with social cognition.

A team of scientists led by doctors Rafael de la Torre at Hospital del Mar Medical Research Institute (IMIM) and Mara Dierssen at the Centre for Genomic Regulation (CRG) have shown that epigallocatechin gallate together with a cognitive stimulation protocol, might improve some cognitive domains in individuals with Down’s syndrome. The results of the phase 2 study will be published on 6th June in the prestigious journal The Lancet Neurology. The findings suggest that participants who had received the treatment had better scores in the visual memory recognition and inhibition tasks, and improvement in adaptive behaviour than those in the control group (placebo and cognitive training). Though not a cure, this is the first time that a treatment has shown some effectiveness in this syndrome, and it opens the door to new research geared towards treating what was believed to be orphan of treatment.

Researchers from the Hospital del Mar Medical Research Institute (IMIM) in collaboration with scientists from Pompeu Fabra University, the Pasteur Institute andPierre and Marie Curie University, have discovered a crucial neural mechanism that explains the process of nicotine reward and addiction. Nicotine, the principal psychoactive component of tobacco, is quickly absorbed through the nasal, oral and respiratory membranes and takes 7 seconds to reach the brain where the receptors are located. It is there where it acts on the central nervous system as well as the autonomic nervous system. This almost immediate relationship between the inhalation of the smoke and its effect at a cerebral level is one of the factors contributing to the highly addictive nature of nicotine. This is explained by the fact that the nicotine exerts its psychopharmacological effects by activating receptors that are very abundant in several specific regions of the brain, the nicotinic acetylcholine receptors (nAChR).
