Psychological and Neurological Impacts of Stress and COVID-19

These flashcards focus on key concepts related to the psychological and neurological impacts of stress and COVID-19, including the role of oxytocin, cognitive deficits observed in COVID-19 patients, and the benefits of exercise on brain health.

Oxytocin

A hormone that is considered a potential treatment for depression, anxiety, and PTSD, showing mixed results in clinical studies.

HPA Axis

The hypothalamic-pituitary-adrenal axis, a major part of the stress response system that oxytocin dampens.

Anhedonia

A reduced ability to experience pleasure, which oxytocin is noted to counteract.

Cognitive Deficits

Impairments in cognitive functions such as attention, memory, and problem-solving, as seen in COVID-19 patients.

BDNF (Brain-Derived Neurotrophic Factor)

A growth factor that promotes the differentiation of new neurons and supports neuron survival; increased by exercise.

Neurogenesis

The process by which new neurons are formed in the brain, enhanced by exercise and learning.

Cortisol

A stress hormone whose production is elevated by prenatal stress, affecting receptor density in the hippocampus.

Bidirectional Relationship

A mutual influence where COVID survivors are at risk for psychiatric illnesses, which in turn increase the risk for COVID.

Synaptic Plasticity

The ability of synapses to strengthen or weaken over time, influenced by oxytocin and experiences.

Active Lifestyle

Engagement in activities that promote physical health, cognitive function, and brain plasticity throughout life.
