Which source and year define biological aging as progressive physiological decline?
López-Otín dkk., 2023.
How can aging-cell molecules disrupt cell function in the microbiological theory?
They connect, adhere, and accumulate, potentially stopping vital biochemical cycles and causing further damage.
How does aging affect the immune system’s ability to fight infection?
Its ability to recognize and fight bacteria and viruses diminishes, increasing susceptibility to infection.
When does aging begin?
In early adulthood.
What happens to neuron numbers in older adults?
They lose some neurons.
Which brain regions shrink especially with age?
The prefrontal cortex and hippocampus.
What cognitive changes define dementia, and which type is most common?
It affects memory, thinking, and behavior; Alzheimer's disease is the most common type.
What functions does Alzheimer's disease gradually impair?
Short-term memory, thinking ability, and personality.
When does visual decline begin, and what happens to the lens?
Visual decline begins in middle adulthood, and the lens loses elasticity.
What sensory changes can cochlear deterioration cause?
It reduces hearing ability and, in severe cases, hearing may be limited to murmurs.
