All other conditions and ailments are preventative and are a product of mistreatment...Simply NOT true !

A statement at Ivyology says:

" A popular misconception is that physical or mental ailments are a result of old age. A fading memory, dementia, aches and pains are not a result of ageing! There have been so many times when I’ve heard, “oh, it’s just old age”. The only things that are a result of old age are wrinkles and grey hair. Yup! All other conditions and ailments are preventative and are a product of mistreatment or simply not knowing how to avert them."

The high lighted part of the statement is a misconception in itself.
Memory loss is a symptom that can be associated with dementia.There is currently no prevention or cure for most forms of dementia; however, symptoms may be reduced with medication. Wrinkles and grey hair are NOT symptoms of or caused by old age alone. Not all forms of dementia are a result of mistreatment nor are ALL forms of dementia preventative. Some of the most common forms of dementia

* Alzheimer’s disease
* Vascular dementia
* Parkinson’s disease
* Dementia with Lewy bodies
* Huntington’s disease
* Alcohol related dementia – Korsakoff’s syndrome
* AIDS related dementia
* Fronto Temporal Lobar Degeneration (FTLD)
* Creutzfeldt-Jakob disease.

There are many other rarer causes of dementia, including progressive supranuclear palsy and Binswanger's disease. People with multiple sclerosis, motor neurone disease, Parkinson's disease and Huntington's disease can also be at an increased risk of developing dementia. A lot of these are not preventable and some may even be hereditary. See the following link:
