Coffee can be good for your brain

Several studies have suggested that daily caffeine administration can protect against brain injury in some cases, for example in animal models of neurodegenerative diseases, such as Parkinson’s and Alzheimer’s diseases, as well as in ischemic and traumatic brain injury, or allergic encephalitis. Olga Valverde’s group at the CEXS-UPF decided to check if it could also have a positive effect on MDMA-induced neuroinflammation. The recreational drug MDMA, or ecstasy, induces astrocytic and microglial activation in mice striatum, which leads to inflammation and neurotoxicity. They injected caffeine (10, 20, or 30 mg/kg, i.p) for 21 consecutive days into mice, and then on day … Continue reading Coffee can be good for your brain

The effect of genes and environment on the consequences of ecstasy use

The Human Pharmacology and Clinical Neurosciences group of the IMIM-Hospital del Mar, lead by Rafael de la Torre, has published a paper in PLoS One  this week to try to clarify the association between cumulative use of MDMA (ecstasy), one of the most popular illegal psychostimulants abused among youth,  and cognitive dysfunction. They have also set to understand the potential role of candidate genetic polymorphisms in explaining individual differences in the cognitive effects of MDMA. Several studies have suggested that MDMA induces neurotoxicity, which primarily affects the serotonin system and is linked to memory dysfunction. There is also evidence that several gene polymorphisms may contribute to explain variations … Continue reading The effect of genes and environment on the consequences of ecstasy use
