An ounce of prevention is worth a pound of cure

 
 
 

It’s known that Omega-3 fatty acids have an important role in the development of cognitive functions, but some recent studies have showed that they, besides, may be useful in the prevention of cognitive decline and dementia.

In aged persons, there’s a transitional phase between mild cognitive decline and disabling dementia when it’s not clear whether the deficits predict dementia or not and the mild memory or cognitive impairment cannot be explained by any medical or psychiatric condition. In this phase, according to these studies, appropriate dietary measures and supplementation with Omega-3 fatty acids achieve the maintenance of adequate cognitive functioning and possibly have beneficial effect on the risk of dementia (of degenerative or vascular origin), preventing or delaying its onset. It’s important to emphasise that this has been observed during this period, with mild cognitive disorders (with different features, manifestations and probable cause) associated with aging, but not when the disease process has already taken over.
