Blood-Vessel Damage Studied in Alzheimer’s

Damage to small blood vessels in the brain may play a role in causing Alzheimer’s disease, a small study suggests. The study included 20 people who had been diagnosed with Alzheimer’s and 21 who did not have it. It also included 59 people who had mild cognitive impairment. People with this milder memory problem have an increased risk of Alzheimer’s disease. Researchers looked at information from brain scans. In some people, the scans showed amyloid plaque deposits in the brain. This has long been considered a sign of Alzheimer’s disease. Some people also had areas of intense white matter in the brain. These areas indicate damage in small blood vessels. People with amyloid deposits who had been diagnosed with Alzheimer’s had larger areas of intense white matter than normal subjects.

Most Breastfeeding Mothers Stop Early

In a new survey, about 60% of new mothers who started breastfeeding said they had stopped before they planned. The study included 1,177 U.S. women. They responded to monthly surveys that began when their babies were 2 months old and ended at age 1 year. Women were asked each time whether they had stopped breastfeeding. If the answer was yes, they were asked whether they breastfed as long as they wanted. They also rated the importance of 32 possible reasons for stopping. Problems with breastfeeding ranked at the top of the list. These included difficulties with getting the baby to latch on, cracked or bleeding nipples and infected breasts. The other most common reasons were concerns about the baby’s nutrition and weight, the mother’s illness or need to take medicine, and the effort required to pump milk.
