High altitude residency potentially reshapes the brain's emotional processing mechanisms
Living at high altitudes can have a significant impact on emotional neural processing, according to a recent study. The research, conducted with participants who had moved to high altitudes for university, reveals that chronic mild oxygen deprivation (hypoxia) disrupts brain neurochemistry and mood regulation, potentially leading to emotional dysregulation or mood disturbances.
Hypoxia at high altitude specifically targets serotonin, a key neurotransmitter in mood regulation, in the prefrontal cortex. This disruption can impair neural circuits responsible for regulating emotions and stress responses, increasing vulnerability to anxiety, depression, or other mood fluctuations.
The alteration may manifest as a reduced "positive bias" in how the brains of high-altitude individuals process the emotional world around them. High-altitude residents showed a reduced response to happy faces, taking longer to recognize emotional expressions compared to those living near sea level.
Moreover, high-altitude exposure can cause physiological stress combined with emotional challenges, requiring resilience and adaptability. Psychological resilience appears crucial in managing such emotional fluctuations, though most of the detailed research on resilience focuses more on cold exposure than altitude specifically.
High-altitude hypoxia may also reduce cortical communication efficiency and increase neural excitability in emotion-related brain regions, potentially heightening anxiety or emotional reactivity. Neural pathways connecting the heart and brain, such as the vagus nerve, also play a role in emotional regulation and cognitive flexibility. Better vagal tone (cardiac vagal activity) is linked to improved executive functioning and emotional resilience, which could be relevant in mitigating altitude-related emotional processing challenges.
Understanding the neural pathways connecting hypoxia to emotional processing could potentially lead to better treatments for conditions like sleep apnea, COPD, and cardiovascular conditions. Short periods of oxygen supplementation might help counteract chronic mild hypoxia for those living at high elevations who experience symptoms of depression.
People living at high elevations face up to three times higher rates of depression and suicide compared to those at sea level. The brain changes identified in this study offer a potential explanation for the higher rates of depression among soldiers, migrants, and native populations living at high altitudes.
Limited mental health resources are a factor in the high-altitude/depression link, as rural mountain areas frequently lack adequate psychological services. Social isolation is another factor, as remote mountain communities often offer fewer opportunities for social connection.
Whether genetic adaptations in indigenous high-altitude populations extend to protective effects on emotional processing remains an open question. The new research reveals that chronic mild oxygen deprivation at high altitudes produces specific changes in how the brain processes emotional information, offering a potential neurological explanation for the long-observed connection between high-altitude living and increased rates of depression and anxiety.
