A recent neurological study has found that social isolation not only affects a person's mood, but can also cause physical changes in the brain. According to research, being alone for long periods can lead to shrinkage of certain areas of the brain, decreased dopamine, and impaired memory.
Scientists have observed polar expedition teams for a 14-month period and have found a significant decrease in the protein BDNF (Brain-Derived Neurotrophic Factor), which is essential for the growth and survival of neurons. At the same time, a shrinkage of the hippocampus, the area of the brain associated with learning, memory and spatial orientation, was also observed.
According to researchers, while a short period of solitude, such as two weeks, does not necessarily cause permanent damage, prolonged isolation can lead to a significant decline in cognitive abilities. Tasks that require concentration and memory become more difficult over time.
However, experts emphasize that the effects of short-term isolation are reversible. The study highlights the importance of social interaction and environmental stimulation for maintaining neurological health in the long term.
