Scientists Explain Why the Brain Weakens with Age
The weakening of the brain with aging is a natural process influenced by multiple scientific factors. According to experts, neurons gradually shrink and die, reducing memory and cognitive speed.
Neurotransmitters such as dopamine and serotonin decline with age, affecting mood and focus. In addition, narrowing blood vessels reduce oxygen supply to the brain, limiting energy.
Researchers highlight that oxidative stress, accumulation of toxic proteins, and hormonal changes further increase the risk of neurological diseases such as Alzheimer’s and Parkinson’s.
