Dr. Alexander Villareal, MD, has been an integral part of the multidisciplinary team at the Geisinger Sleep Disorders Centers. Dr. Villareal earned his medical degree from Nuestra Senora de La Paz University in Bolivia in 1999. In 2005, he completed a 3-year residency in internal medicine at Henry Ford Hospital in Detroit, followed by a 2-year fellowship in sleep medicine at the same institution. Board certified in internal medicine and sleep medicine and director of sleep medicine at Geisinger Sleep Disorders Centers, Dr. Villareal became interested in this health niche during his pulmonary medicine residency. “I found the topic of sleep apnea fascinating and asked to have an elective in sleep medicine. That [experience] increased my interest and passion in the subject,” Dr. Villareal says. Dr. Villareal treats adult patients who present with sleep apnea; insomnia; parasomnias, including sleep walking, night terrors, teeth grinding, and other sleep issues; restless legs syndrome; and narcolepsy. Additionally, his patient load includes adolescents and school age children with non-sleep apnea problems, such as narcolepsy, insomnia, and delayed sleep syndrome. Dr. Villareal bases his treatment options on standard medical care and scientific evidence in collaboration with the patient. “I always involve the patient in the decision. I ask them their preference,” he says, adding that he attempts to increase the patient’s understanding of their particular sleep condition. “I educate them about the diagnosis and treatment options and share the reasons behind my advice. If they understand, they can make better choices, which leads to better compliance.”
