Neurogenis and Dementia

Those of you who read my earlier blog will remember what neurogenesis is. To recap, its the growth of new brain cells which happens when certain stimulus conditions are reached. In the past it was taught that this was entirely impossible once you're of adult age. So a lot of programs were devised and sold to parents emphasising early development of the brain. Years ago I was one of those who bought into this concept for my daughter when she came into this world. There are still many products out there which pitch on early brain stimulus and concerned Singaporean parents are buying. Right brain development; Shuhida methods; Montessori, Multiple Intellgence, etc sell big ticket items and courses still.

Scientists also use the term neuro-plasticity in conjunction with neurogenesis. What is recently discovered is that there are stem cells in the brain. More about that later.

Today I am heartened to read form BBC that activity will easily preclude dementia! If you want details, follow the link by clicking on the word.

'Dementia is caused by the massive loss of cells in the brain, and experts believe one way to guard against it is to build up as many connections between cells as possible by being mentally active throughout life. This is known as a "cognitive reserve".' These connections are between the dendrites of the various neurons and are called synapses. The more synapses you care to build, the more connections and therefore the more cognitive reserve!

So what causes the loss of cells? I think it is no more than what we generally know as "Use it or lose it"

Does 'connections' ring a bell with you? For me it means as we age, we should reach out and find more friends and even blog. Build your connections now. Let there be no lack of synapses in your grey matter.

Neurogenesis

Okay here's one for those my age. What happens when you try new things, will you be able to learn again? Will your brain still grow new brain cells? (called neurons)

One of the most important developments in neuroscience was when the official dogma claiming that there was no neurogenesis (production of new brain cells) in the adult brain was toppled. Now we know that the brain is “plastic” meaning that, under the right circumstances, the brain can change in terms of both producing new cells and getting more cells connected to each other.

This is good news to all seniors. Its time to get off the couch and live life to the full! Learn a new musical instrument or start blogging - its good for the brains. I now have blogging neurons; hoorah!

Ahem,... I assume brains are needed for blogging. Last night, a good friend pointed out that brainless blogs do attract quite a readership too.

Also, I went to the mensa page (www.mensa.org.sg)and it looks like a blog or run by a blog engine. Is it or isn't? Any one care to elucidate?
