My husband has been diagnosed for 13 years now. He is 73. The first five years he did very well with lots of biking then walking after several bike crashes. Then two broken legs from two different falls, both in the home simply walking and turning.
Since then the dementia has steadily progressed. His neurologist has him on namenda. He has no other ideas about what to do .
It really breaks the families heart to see such a steep decline in a once smart and active person.
