Cholesterol for Brain Development

When an adult received his or her medical report from the pathlab or any related medical institutes, he or she would normally look closely at the number shown besides the words "cholesterol level".

Laymen out there often regard cholesterol as a bad constituents and they usually hope that they could put a efforts in eliminating these so-called hazardous cholesterol. But as a matter of fact, cholesterol actually can be generally categorized into two different categories, namely good cholesterol, HDL (High density lipoprotein) and bad cholesterol LDL (Low density lipoprotein).

If the amount of LDL cholesterol appears to be too much in the bloodstream. Eventually, this could lead to the formation of plagues and this consequently impair the flexibility of the arteries. Gradually, diseases such as atherosclerosis could occur.

On the other hand, when the high amount of HDL cholesterol present in the blood stream, they tend to carry the fats away from the arteries and bring them back to the liver. Thus, this could lower the risk of heart disease occurrence.

The details above are just for your additional information, but what we are going to discuss today, is about a new study which indicates that cholesterol proves to be a vital substances in brain development.

The research, led by Professor Ernest Arenas from a Swedish medical university, Karolinska Institutet, had demonstrated that a specific receptor in the brain by an oxidised form of a type of cholesterol called oxysterol is responsible in the formation of dopamine-producing neurons during brain development in mice.

Professor Arenas further postulated that the loss of oxysterol could be one of the main causal factors in the stimulation of Parkinson's Disease.
