Finding: Adults Can Make New Brain Cells Even in 70's

In summary, a new study published in the journal Cell Stem Cell has found that adults continue to make new neurons in the hippocampus, even in their 70s. This discovery challenges the previous belief that humans stop producing new brain cells after birth and offers hope for our aging brains. These new neurons have been shown to help with memory and emotional regulation, and may have implications for disorders such as bipolar disorder. While previous studies have shown the benefits of meditation for building brain cells, this new research suggests that age may also play a role.

Whether or not adults make new brain cells has been a constant topic of debate. A new study published today offers hope for our aging brains with the discovery that adults continue to make neurons even in old age. https://www.ncbi.nlm.nih.gov/pubmedhealth/PMHT0024269/help us perform daily functions by sending message from our brains to the body.

Until the 1960s, scientists believed that humans stopped making neurons not long after birth, Scientific American reported in March 2018. But as research grew, scientists found more evidence to indicate that our brains continued to evolve. Last month, research published in the journal Nature challenged this belief with a study that determined adult brains had no traces of new neurons.

Now, a study published in the journal Cell Stem Cell indicates that our brains continue to make neurons in the hippocampus as we age. This has been shown to help in making memories and managing emotions during stressful times, according to study co-author Dr. Maura Boldrini of Columbia University.

Cool stuff.

Interesting. As a layman, this makes me wonder if this could somehow be related to the development of affective disorders such as bipolar disorder.
 

1. How is it possible for adults to make new brain cells in their 70s?

It was previously believed that the brain cells, or neurons, in adults were fixed and could not be replaced. However, recent studies have shown that certain areas of the brain, such as the hippocampus involved in memory and learning, continue to produce new neurons throughout adulthood. This process is known as neurogenesis.

2. What are the benefits of adults being able to make new brain cells?

Neurogenesis has been linked to improved cognitive function, such as memory and learning, as well as increased resilience to stress and anxiety. It may also play a role in the treatment and prevention of certain brain disorders, such as Alzheimer's disease and depression.

3. Can lifestyle factors affect the production of new brain cells in adults?

Yes, lifestyle factors such as exercise, diet, and social interactions have been shown to promote neurogenesis. Engaging in regular physical activity, consuming a healthy diet rich in omega-3 fatty acids and antioxidants, and maintaining social connections can all support the production of new brain cells in adults.

4. Is there a limit to the number of new brain cells that can be produced in adulthood?

While neurogenesis does occur in adults, it is not a limitless process. The rate of neurogenesis tends to decline with age and can also be affected by various factors such as chronic stress and certain medications. However, research has shown that the brain has the potential to continue producing new neurons well into old age.

5. How can we encourage neurogenesis in adults?

In addition to maintaining a healthy lifestyle, there are other ways to promote neurogenesis in adults. These include engaging in mentally stimulating activities, such as learning a new language or musical instrument, and getting enough quality sleep. Additionally, certain supplements, such as omega-3 fatty acids and curcumin, have been shown to support neurogenesis in adults.
