As attention turns to new drugs that can address the growing burden of Alzheimer’s disease (AD) in an aging global population, Retispec Inc. has developed a noninvasive test that may be able to detect early signs of the neurodegenerative disease decades before clinical symptoms appear – and when therapies appear to be most helpful in slowing or reversing Alzheimer’s. By using “off-the-shelf” ophthalmic equipment, the Toronto-based company’s solution enables assessment by optometrists or other eye professionals during a standard eye exam.
