After any brain injury, even a mild one, there tends to be a drop or loss of IQ, but this score usually improves as time passes. This fact leads researchers to argue that most “intelligence loss” after brain injury is really just a result of trauma.
Pump up the pink noise
But pink noise, in which lower frequency sounds are more powerful—like the rush of a waterfall or pounding rain—may boost your brain, according to a study published in 2017 in Frontiers in Human Neuroscience.
The IQ was calculated by dividing the individual’s mental age (determined by performance on the test) by his or her chronological age and multiplying by 100. Today, the most commonly-used IQ test is the Wechsler Adult Intelligence Scale.

What Is The Lowest IQ Score? The lowest IQ score is 0/200, but nobody in recorded history has officially scored 0.

That’s why a glass of OJ or another fruit juice can offer a short-term boost to memory, thinking, and mental ability. Have too much, though, and memory can be impaired — along with the rest of you. Go easy on the added sugar, as it has been linked to heart disease and other conditions.
REM sleep, or the dreaming phase of sleep, has been shown to enhance learning, memory and emotional well-being. Sleep disruptions affect your levels of neurotransmitters and stress hormones, which may make it more difficult to think and regulate your emotions.
As we turn our clocks back one hour this weekend for daylight saving time, if we sleep that extra hour many of us will become smarter because of it. Studies show that when we allow our bodies to rest more, it helps our brains — with memory, concentration and focus.
We call it white noise because it has basically equal power for all frequencies of audible sound—just like white light has equal power for all frequencies of visible light. And just as we call different frequencies of light different colors, we call different mixes of sound frequencies different colors of noise.
Apart from his physical abilities, Peter is an intellectually-gifted scientific teen genius and has a prodigious aptitude in the physical sciences, with a high IQ level of around 250.
