Your brain starts to decline at age 27 – WTF?

Mental powers start to dwindle at 27 after peaking at 22, marking the start of old age, US research suggests.

Professor Timothy Salthouse of Virginia University found reasoning, speed of thought and spatial visualisation all decline in our late 20s. Therapies designed to stall or reverse the ageing process may need to start much earlier, he said.

In nine out of 12 tests the average age at which the top performance was achieved was 22.

The first age at which there was any marked decline was at 27 in tests of brain speed, reasoning and visual puzzle-solving ability.

Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60.

I guess I’m not surprised. There’s a corollary in education that most people stop learning after age 26.

    The silver lining:

    abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60.

    This is a pretty big silver lining, for those who might otherwise lose heart at such studies.
