Ryan O?Neill is only 30 years old. He has a unique and exceptional family story. Ryan?s father died at the early age of 48 from a very rare form of Alzheimer?s disease. Of his father?s 11 brothers and sisters ? 8 of them died at a young age from Alzheimer?s. Ryan has a fifty/fifty chance of having inherited the gene from his father ? if so - he too will die at an early age just like his Dad. Should he do a genetic test and know whether he carries the gene or not?
