Although Alzheimer's is the most common cause of dementia - a catchall term for cognitive deficits that impact daily living, like the loss of memory or language - it's not the only one. Because multiple causes of dementia can happen simultaneously, reaching a definitive diagnosis isn't easy or quick. And often by then, it’s too late to intervene.
Boston University's Vijaya B. Kolachalama, an expert on using computers to aid medical diagnoses, has created an artificial intelligence tool that can determine what’s causing a person's cognitive decline, and assist doctors in more efficiently zeroing in on an accurate diagnosis.
