A few years ago, a nurse came to my Dad's home to conduct some cognitive tests on my Dad (MoCA,Trail Making Test, and MMSE). At that time he was 83 years old, had been a JW for over 25 years, and had been retired for some time (he took early retirement at age 55). He was definitely exhibiting signs of depression as well as dementia.
The nurse told me that they are finding common risk factors amongst people who suffer from dementia/alzheimers. She listed these for me:
- Lack of post secondary school education
- Chronic Depression
- Long term substance abuse including smoking
- Poor lifestyle habits such as bad diet and poor physical activity
From the Alzheimer's Society website ( http://www.alzheimer.ca/en/About-dementia/Alzheimer-s-disease/Risk-factors ), they list:
A healthy lifestyle can help reduce the risk of Alzheimer’s disease and
other dementias. It has been estimated that up to half the cases of
Alzheimer’s disease worldwide may be the result of seven key modifiable
risk factors: diabetes, high blood pressure, obesity, smoking,
depression, cognitive inactivity or low education, and physical
inactivity.
What can I do to maintain or improve my brain health?
• Be physically active
• Avoid smoking and excessive alcohol consumption
• Track your numbers: keep your blood pressure, cholesterol, blood sugar and weight within recommended ranges
• Stay connected socially and interact regularly with others
• Make healthy food choices, eat a well-balanced and healthy diet rich in cereals, fish, legumes and vegetables
• Reduce stress
• Challenge your brain by trying something new, playing games or learning a new language
• Protect your head by wearing a helmet when you engage in sporting activities
Of course there is a genetic link as well (and a test one can take to see if one has the genetic marker) but there are several risk factors that JWs would be prone to. I have/had at least 3 JW family members who suffer(ed) from mental illness.There may be more family members but I don't know as they don't have much to do with me.
