Scientists have discovered that the human brain has the capacity to regenerate cells during adulthood, a process known as neurogenesis. This finding challenges the long-held belief that the brain is fixed and unchangeable post-childhood. The study focused on the hippocampus, the area of the brain associated with memory and learning, where the most significant regeneration was observed.
The study also revealed that stress and ageing can negatively affect neurogenesis. High-stress levels can halt cell regeneration, leading to memory and cognitive issues, while ageing slows down the process. On a positive note, certain lifestyle changes such as regular exercise, a balanced diet, quality sleep, and reducing stress can boost neurogenesis.
In addition to lifestyle changes, certain drugs can stimulate the growth of new neurons. Antidepressants, for instance, promote neurogenesis, which might explain their effectiveness in treating depression. The study suggests that enhancing neurogenesis could be a potential treatment for neurodegenerative disorders like Alzheimer’s disease.
These findings open up new possibilities for understanding the brain’s plasticity and its potential for regeneration. It offers hope for developing new treatments for various mental health disorders and neurodegenerative diseases.
