Connection between Down Syndrome and Alzheimer's

Scientists are attempting to learn more about Alzheimer's by studying and testing patients with Down syndrome.

The genetic disorder, Down syndrome, is related genetically with Alzheimer's.  Persons with Down syndrome have an extra chromosome 21.

Chromosome 21 contains the gene that is responsible for the "sticky plaques" found in Alzheimer's patients.

A SECOND LANGUAGE DELAYS DEMENTIA

A recent study shows that persons who know a second language have significantly later onset of dementia than those who speak only one language.

Previous research had suggested that a person's level of education directly correlated with the age that dementia began, with the most highly educated individuals having later onset dementia. However, this study included geriatric patients who were illiterate, eliminating formal education as a factor, and putting the focus on second language skills.

In the test group of approximately 650 patients, knowing a second language delayed the start of dementia by an average of 6 years.

The patients studied suffered from various forms of dementia including Alzheimer's disease.

The study, reported in Neurology, can be accessed here:

A Frightening 4th - When I Was 6

I was sick on the 4th of July when I was 6 years old. Dad promised, though, that I could use my sparklers when I was well. I was visiting my aunts and grandma at their house a few days later and excitedly told them that I was going to use my sparklers that night. Grandma called an aunt over and asked if it was the 4th of July.

I was terrified at Grandma's question! At the age of 6, I was absolutely certain that adults knew everything. Yet here was my Grandma not knowing if it was the 4th of July! Unthinkable. I didn't tell anyone that I was frightened and no one realized that I was upset about something. I kept trying to puzzle out what was happening. I can still feel how scary it was to realize that an adult might not even know what day it was!

And so all these years later I have written the story of Johnny, a little boy who thinks his grandmother doesn't love him anymore because she is acting differently. Mommy explains about grandmother's illness in a way that makes Johnny happy.

Unlike me, Johnny is sad rather than afraid. Also unlike my true-life experience, Johnny's mom realizes something has upset him and helps him.

I wrote the story to help families cope with a difficult problem that occurs so often: a child dealing with the decline of a loved one. I hope my story is of help to you.Special Secret Hearts: a Child's Introduction to Dementia  http://amzn.to/KhvXA8
