Brain Decline starts at 40s: Study

The brain begins to decline at the age of 45 affecting our memory and comprehension skills, claimed a new study. However, the beginning of dementia can be delayed by living a healthy lifestyle.

Researchers said that the reasoning and comprehension skills start deteriorated at 40s. The study published online by the British Medical Journal suggested that a healthy heart is good for the brain.

In fact, the full-blown dementia usually is seen at old age. But the current stressful lifestyle is responsible for decline of the brain much earlier than old age of 60.

The study was conducted over 7,000 civil servants between 1997 and 2007. The subjects were aged between 45 and 70. They were assessed three times on memory, vocabulary and aural and visual comprehension skills.

The assessment showed that the cognitive scores declined in all categories and the faster decline was noticed in older people. While 3.6 per cent decline was recorded in mental reasoning in men aged 45 between 49, 9.6 per cent decline in aged 65-70 and the decline was noticed in women categories were 3.6 per cent and 7.4 per cent respectively.

However, the decline can be delayed if the lifestyle will be improved at the age of 40. People, who are suffering from risk of heart disease, can avoid such brain decline by following a healthy lifestyle.
