Câu hỏi:

Read the following passage and choose the best answer to each of the following questions from 27 to 34.

1. As people grow older, their brains also go through aging. Every cell in the brain changes, including how genes behave. The brain is made up of many different types of cells, each with special roles and connections. Scientists have discovered that gene activity changes differently in various brain cells as we age. One particular type of neuron is affected the most. These discoveries could lead to ways to slow down brain aging and delay diseases like Alzheimer’s.

2. Researchers from the Max Planck Institute of Psychiatry studied gene activity in brain cells using tissue samples from 90 people aged 25 to 85 who donated their brains after death. Their research focused on the prefrontal cortex, an important area for thinking, planning, and problem-solving.

3. They investigated the activity of genes in individual cells using a method known as single nucleus RNA sequencing. They found that gene expression changes during aging in all types of brain cells, but the specific genes involved differ. Genes that help neurons communicate and produce proteins show changes as people get older.

4. Since age is the main risk factor for neurodegenerative diseases like Alzheimer’s, the researchers compared gene changes during normal aging with those in Alzheimer’s patients. They found many similarities, suggesting that normal aging changes might become harmful if they go beyond a certain point. One type of inhibitory neuron seems particularly affected by both aging and Alzheimer’s disease.

5. The study also compared brains of people with and without mental health disorders. Those with psychiatric illnesses showed signs of faster biological aging, meaning their brains looked older at the gene level. This could explain why people with conditions like schizophrenia might be more prone to brain aging and related diseases.

Which of the following is TRUE according to the passage?

A.

It is important to recognize the need to consider the long-term neurological impacts of mental disorders.

B.

Research on slowing brain aging at the cellular and genetic level is beginning to show promising results.

C.

Focusing on the prefrontal cortex reveals that changes in this area have major impacts on mental health.

D.

Mental health disorders might place additional stress or burden on brain cells, leading to increased aging.
