Analysis had indicated a beneficial effect of the substance on neurons.
However, molecule has jumbled connections between nerve cells.
Some years ago a scientific study supported the thesis that nicotine could have a beneficial effect in the brain of patients with Alzheimer's disease. The hope of finding something good in the habit of smoking fell to the ground with the observation that, in fact, smokers have an increased risk of suffering from dementia with age.

Alzheimer's disease is a devastating picture in which people gradually lose brain functions. The disease is characterized by two types of damage to the brain: the accumulation of a substance, forming a kind of plate and development of a bundle of filaments between the nerve cells.

The initial research with nicotine showed that the plate was lower in smokers, which would be a beneficial effect, but more recent studies show that the development of bundles of filaments increases and appears earlier with exposure to nicotine. To reach this result were studied laboratory mice genetically modified to produce the two types of brain changes.

Currently there are around 20 million people with Alzheimer's in the world, and it is estimated that by 2025 this number should be around 34 million, according to the World Health Organization as the disease becomes more common with age, developing countries which are experiencing an acceleration of the aging of its population, are paying the price ever higher. The perspective is that two thirds of the victims in the year 2025 are in those countries.

Here's another good reason to avoid the smoke.
