Analyzing the disease-related web searches of Internet users provides insight into the interests of the general population as well as the healthcare industry, which can be used to shape health care policies.
We analyzed the searches related to neurological diseases and drugs used in neurology using the most popular search engines in the US, Google and Bing/Yahoo.
We found that the most frequently searched diseases were common diseases such as dementia or Attention Deficit/Hyperactivity Disorder (ADHD), as well as medium frequency diseases with high social impact such as Parkinson's disease, MS and ALS. The most frequently searched CNS drugs were generic drugs used for pain, followed by sleep disorders, dementia, ADHD, stroke and Parkinson's disease. Regarding the interests of the healthcare industry, ADHD, Alzheimer's disease, MS, ALS, meningitis, and hypersomnia received the higher advertising bids for neurological diseases, while painkillers and drugs for neuropathic pain, drugs for dementia or insomnia, and triptans had the highest advertising bidding prices.
Web searches reflect the interest of people and the healthcare industry, and are based either on the frequency or social impact of the disease.
分析互联网用户与疾病相关的网络搜索情况，有助于洞察普通民众以及医疗行业的关注点，进而用于制定医疗保健政策。
我们使用美国最受欢迎的搜索引擎谷歌以及必应/雅虎，分析了与神经系统疾病及神经科用药相关的搜索。
我们发现，搜索频率最高的疾病是痴呆症或注意力缺陷多动障碍（ADHD）等常见疾病，以及帕金森病、多发性硬化症和肌萎缩侧索硬化症等具有较高社会影响的中等频率疾病。搜索频率最高的中枢神经系统药物是用于止痛的非专利药，其次是睡眠障碍、痴呆症、ADHD、中风和帕金森病相关药物。关于医疗行业的关注点，ADHD、阿尔茨海默病、多发性硬化症、肌萎缩侧索硬化症、脑膜炎和特发性嗜睡症在神经系统疾病方面获得了较高的广告出价，而止痛药和治疗神经性疼痛的药物、治疗痴呆症或失眠的药物以及曲坦类药物的广告出价最高。
网络搜索反映了民众和医疗行业的关注点，且这些关注点基于疾病的发生频率或社会影响。
