People who want to find out if something has affected their loved ones or themselves can access cheap DNA tests to confirm or deny the possibility of what they have, according to a recent report.
The Scotsman looked into a range of diseases which affect hundreds of thousands of people in the UK alone, noting that in particular, Huntington's disease, dementia and Parkinson's disease can be picked up through scientific methods.
Perhaps the easiest one to detect is Huntington's, on account of its transmission, it was argued.
The Scotsman continued: "If you have a parent with Huntington's disease, there is a 50-50 chance of inheriting the faulty gene. Anyone who inherits the faulty gene will, at some stage, develop the disease."
Earlier in the month, it was announced that Dimebon, an Alzheimer's disease drug, appears to be safe and effective for Huntington's disease patients and has minimal side-effects, according to the journal Archives of Neurology.
