In addition, searches are also conducted by physicians and medical students, who make up a higher percentage of the population in smaller university cities.

“The high search volume regarding therapy suggests a need for more information about the disease and its treatment options,” the investigators commented. “Furthermore, the influence of climate on search volume indicates higher medical need during the winter months, which should be considered in everyday clinical healthcare and medical guideline development. Combining seasonal adjustment of treatment plans with holistic therapies and patient education programs can optimize effective AD management and improve future allocation of healthcare resources.”
