Several drug companies have abandoned Alzheimer's disease treatments recently after setbacks. But the Wall Street Journal says scientists keep moving forward with a focus on earlier intervention. Last year, the National Institutes of Health will have poured an estimated $1.35 billion into Alzheimer's disease, almost triple its investment for fiscal year 2013.

Amazon founder and CEO Jeff Bezos is now worth more than Bill Gates ever was. The internet retailer's shares have risen 6.6 percent, making him worth $105 billion, according to Bloomberg's Billionaires Index. Gates, though, would be worth $150 billion if he'd held onto assets that he's given away.

Tax refunds encourage spending on health care. Fox Business says data collected by the JPMorgan Chase Institute found that the overall level of health care spending is 60 percent higher in the week after receiving a tax refund payment than in a typical week over the 100 days before. They say it shows many Americans put off health care until their refund is put into their bank accounts.

Weight Watchers, whose stock has skyrocketed since Oprah Winfrey bought 10 percent of the company in October 2015, got another lift Monday. The dieting company's shares jumped 12 percent in trading. Investors are presumably thrilled at the enormous and unexpected round of positive publicity for Winfrey's brand after she gave a speech at the Golden Globes awards ceremony.
