Does the Brain Power Deteriorate with Age – Are Young People Smarter Than Old People? Smart Pill Wiki 3

Just like all other parts of the body, brain languishes with each passing year. However, transmutations of the brain could bring a hefty impact since the brain is the ‘engine’ of the human body. A brain has sundry regions that perpetrate different functions like manoeuvrability, ability to remember, learning, speech, and even other internal functions like metabolism. Wear out of the nervous system impacts on cognitive ability and reduces the brain power generally.

How does the Brain Change with Age?

Neuroscientists claim that an individual’s age can be reckoned by looking at the brain’s depict. Brain changes start from the fetus, infants all through to the old age. Individuals have a far much distinct brain during old age.

Neurons get run-out over years whilst the neurology hyperventilates reduces the cognitive ability especially when a human being hits the belatedly 20s. The changes in the brain with age are eerie, but aging is a natural and irremissible process for every individual. By and large, not all the alterations that occur due to age impact negatively.

  • Fetus
  • Even before the little one is delivered the nervous system is already working. Neuroscientists have stated that even when the fetus is 22 weeks old in the uterus, the fetus nervous system is able to grasp. As an exemplary, a fetus reacts to reiterated stimulation such as sound, yet after some time the response is shrugged off.

    Neuroscientists claim that a newborn is able to recall certain music auscultated while inside the uterus. Henceforth, to ensure the fetus brain is healthy, pregnant mothers should observe vigorous practices, eating a nutritive diet, physical work out, avoiding the hassle, and keep off from inebriant and tobacco.

  • Infants
  • When the neonate is delivered, the brain contains 100 billion brain cells which surprisingly maintain the same figure up till weakness. The infant has elementary lastingness swings and five stimulations (touch, sight, hearing, taste, smell.) Within the 2 years after the bambino is born rapid brain alterations occur. Brain cells or neurons multiply in numbers and as well become more efficient.

    Neurons also connect with one another causing sensations to take the perception form. Proper nutrient involving sufficient brain nutritious and sensations make the five senses finer. Although the capability to learn starts even before birth, during infants’ years the capability advances incredibly. By the time the bairn is two years, the brain has undergone immense changes; it almost 80% of the adult brain.

  • Childhood
  • As the nipper crosses the age milestones brain functions improve. The kiddy becomes more intelligent. At this stage, a progeny is able to saunter, communicate, socialize with others, and blackboard learns. The mental prowess is well-developed; the mesencephalon is able to comprehend, gain acquaintance, and retain information. Motor, personal, and cordial expertise improves each passing day during nonage.

    Amazingly in this phase, the child starts to imagine. Surprisingly, the nervous system at this stage has twofold the numeral of neural connections as an adult’s brain. A baby is delivered with 2510 neural connections in each neuron and over time (1-3 years) the number reaches 15000.

    However, they undergo pruning. Synapses that are used e.g. synapses associated with language are reinforced whereas unused synapses taper off and die naturally. Brain pathways are established during juvenility and therefore it is necessary to feed the child with sufficient healthy proteins like eggs and fish to assist in brain growth. Additionally, if possible sugary foods should be kept a bay.

  • Adolescent/ Puerile
  • At jejune, the brain is already three pounds by weight of an adult’s brain. Although a human’s brain at this stage has the same size like a fully developed person’s brain, inner wiring is still taking place, and such a phenomenon could be explained by the weird behaviors of teens at times. The frontal lobes become enormously energetic allowing the adolescent to perform different skills at the same time. Pruning also occurs with sensory and motor handiness strengthened more.

  • Adulthood
  • Dorsolateral prefrontal cortex which is answerable for controlling whim, opinion and decision-making matures at adulthood (the 20s.) The region manages feelings and is frequently regarded as the CEO of the neurology. At late 20s process creeps in.
    Cognitive skills such as reasoning, reaction time, and spatial skills start to deteriorate.
    The brain decreases in volume and the myelin sheath starts to degrade. During the late 30s memorizing things or learning new things becomes difficult. The progression is sluggish, stable, calm, and progresses all through to when one is old.

  • Middle Age
  • Between mid-the 40s to mid-50s, the way of thinking gets worse. Brain functions (logical reasoning, ability to remember, and oral glibness) slow down progressively. This is due to wearing and tearing of neurons due to aging. However, not every change is bad. Researchers claim that a few brain functions improve during middle age such as moral decision-making, management of emotions, and evaluation of common circumstances. Generally, a person becomes smart and wiser. This explains why older people are smarter than young people. Also, as a person grows cognitive content and knowledge increases too.

  • The 60s or Old Age
  • Old age memory loss kicks in at such a stage. The human brain has mislaid efficiency in using the knowledge acquired over the years. A person has gained lots of knowledge and experience but the brain cannot access. At 60s people are at higher risk of suffering from Alzheimer’s disease.

  • The 70s and 80s
    The rate of neurons damage and loss of cognitive ability is very high at this age. Brain volume reduces speedily and debris builds up in the hippocampus which affects long-term memory.

How does Aging affect the Brain?

Aging affect

Age affects the structure, chemistry, and the function of the brain. Additionally, cognitive functions are also affected by age. Changes due to age include shrinking of the brain both in size and volume, dendritic sprouting, and reduction in the number of synapses. White matter lesions or deposits build up in the hippocampus putting a person at very high risk of getting Alzheimer’s disease. The myelin sheath starts deteriorating which slows down the speed of signals


There are quite a number of changes to the brain due to age. The size and volume reduce causing decreased brain functions such as reasoning and memory. Although, the aging process cannot be avoided or reversed there are various things that can help in keeping the brain well-functioning and healthy.
Such things include eating wisely, exercising both physically and mentally, learning new things, and avoiding stress. Moreover, memory loss at young age occurs and has been associated with brain tumors, drugs, and other medical conditions.
