Glasgow, UK: Xeroderma pigmentosum (XP) is a rare and devastating genetic disorder characterised by an inability to repair skin damage caused by ultraviolet (UV) light. As a result, patients with XP develop skin cancers, usually in childhood. Once diagnosed, they can be protected by avoiding sunlight (hence sometimes being called ‘children of the night’), wearing […]

Blood biomarkers plus genomics predict common disease risk more accurately than genomic information alone
Glasgow, UK: Being to identify people at high risk of chronic disease means that they can be targeted with prevention measures before they become sick. Polygenic risk scores, where genomic information alone is used to assess the risk of developing diseases, have been receiving a lot of attention recently, but research presented at the annual […]
World first: Researchers identify specific regions of the brain that are damaged by high blood pressure and are involved in a decline in mental processes and dementia
For the first time, researchers have identified specific regions of the brain that are damaged by high blood pressure and may contribute to a decline in mental processes and the development of dementia. High blood pressure is known to be involved in causing dementia and damage to brain function. The study, which is published in […]
Identification of the genetic causes of childhood epilepsy shows the way to improved treatment and care
Epilepsy is one of the most common chronic neurological diseases, affecting more than 50 million people worldwide. Although it is believed that a large proportion of childhood-onset epilepsies are caused by genetic changes, it remains unknown precisely how many of these patients suffer from a genetic disorder and how often the treatment can be targeted […]
Stressed brain linked to broken heart
Heightened activity in the brain, caused by stressful events, is linked to the risk of developing a rare and sometimes fatal heart condition, according to research published in the European Heart Journal [1]. The study found the greater the activity in nerve cells in the amygdala region of the brain, the sooner the condition known […]
High blood pressure in midlife is linked to increased brain damage in later life
Higher than normal blood pressure is linked to more extensive brain damage in the elderly, according to a new study published in the European Heart Journal [1]. In particular, the study found that there was a strong association between diastolic blood pressure (the blood pressure between heart beats) before the age of 50 and brain […]
Scientists discover what happens in our brains when we make educated guesses
Researchers have identified how cells in our brains work together to join up memories of separate experiences, allowing us to make educated guesses in everyday life. By studying both human and mouse brain activity, they report that this process happens in a region of the brain called the hippocampus. The study, published in the scientific […]
