Preventing cognitive impairment

 
 
 

Omega-3 polyunsaturated fatty acids (group to which EPA and DHA belong) have anti-inflammatory effects and neuronal protective functions, and may be beneficial in the prevention of dementia.

Dementia occurs when cells of the brain are damaged by some health condition, and it is characterized by the impairment of cognitive abilities such as attention, memory, language, logical reasoning, and problem-solving, as well as by the ocurrence of changes in mood or behaviour. This impairment may be mild at first, but becomes severe enough to affect daily life over time.

A healthy lifestyle can help reduce the risk of dementia: exercising regularly, maintaining a healthy weight, not smoking, drinking in moderation, and to follow a balanced diet (low in saturated fat, salt, dairy and meat; abundant in fish, fruits and vegetables). To be socially and mentally active when we get older may also help lower the risk of dementia.

Higher intake of fish and additional daily omega-3 intake (specially DHA) for more than six months can prevent dementia in persons with mild memory or cognitive impairment.
