A study being reported in the September 12, 2006, issue of Neurology, finds that adults over the age of 60 who complain of severe memory problems may actually be losing brain tissue. Despite scoring well on standard memory tests, the adults in the study who complained of significant memory loss were found to have loss of grey matter of about 3% on MRI brain scans. Patients diagnosed with mild cognitive impairment (early Alzheimer's ) show about 4% loss of brain tissue in the same areas of the brain - the areas where memory is stored.

Beginning in 2007 Medicare beneficiaries who earn more money will pay higher premiums for their Medicare Part B coverage. A provision of the 2003 Medicare Modernization Act calls for a change in the formula for assessing Part B premiums. The Part B premium has been based on Medicare covering 75% of the premium costs and the beneficiary paying for 25%. With the changes, higher income beneficiaries will pay a higher percentage of premium costs. For those making more than $80,000 (single) or $160,00 for couples the percentage of the premium will increase to 28.3 % in 2007, 31.6% in 2008 and 35% in 2009. Those beneficiaries with even higher incomes will see large percentage increases.
