Comedian and actor Robin Williams, who had fought substance abuse and depression, was found dead in his California home August 11. The Marin County sheriff’s office said the cause of death was suspected to be “suicide due to asphyxia.” Mr. Williams, 63, had been “battling severe depression,” his publicist said in a statement. After starring in the TV show “Mork and Mindy” in the 1970s, Mr. Williams had an honored film career. He created memorable characters in “Good Morning, Vietnam,” “Aladdin,” “Dead Poets’ Society” and “Mrs. Doubtfire,” among others. He won an Oscar in 1998 for playing a therapist in “Good Will Hunting.” Mr. Williams struggled at times with addictions to cocaine and alcohol. In 2006, he checked himself into a rehab center to be treated for alcohol addiction. He said at the time that he had fallen off the wagon after 20 years of sobriety.
Home testing can help to diagnose sleep apnea just as well as an overnight stay in a sleep lab, new guidelines from a major group of doctors say. People with sleep apnea stop breathing, briefly, many times each night. This can cause daytime sleepiness. The condition also has been linked with a higher risk of heart attack and stroke. Sleep apnea is usually diagnosed after overnight monitoring in a sleep lab. But home monitors have been used increasingly because they cost less and can be used by people who are not near a sleep lab. And research suggests the home monitors do the job, the American College of Physicians (ACP) says. ACP doctors provide primary care for adults. The new AAP guidelines say these home studies are fine for diagnosis of sleep apnea in most people.
Older adults who have low blood levels of vitamin D may be more likely to develop dementia, a study suggests. The analysis is based on data from a study of heart health. Researchers gave tests of mental function to more than 1,600 adults age 65 or older. They also measured vitamin D levels in the blood. They repeated the tests of mental function 6 years later. The new study analyzed the links between vitamin D levels and dementia risk in this group. People with low levels of vitamin D were 70% more likely to develop Alzheimer’s disease as those with normal levels. Those with very low vitamin D levels were more than twice as likely to develop Alzheimer’s. Results were similar for the risk of dementia from all causes. People with low levels of vitamin D had a 53% higher risk of dementia.
