COVID can literally “suck out” motivation: people with COVID were found to have damage to the brain’s dopamine system associated with apathy and memory problems, — eBioMedicine
📍People with long COVID were found to have a significantly lower density of dopaminergic nerve endings in brain regions associated with motivation, movement, and thinking.
📍The stronger the changes in the dopamine system, the more pronounced the apathy, slowed movements, and memory problems were.
📍In other words, the state in which after COVID someone doesn’t want to do anything, finds it hard to make themselves do anything, and experiences reduced concentration and memory, may have a wholly physiological basis in some people.
📍The study included 24 people with long COVID and 24 healthy participants of the same age. Brain changes were studied using PET scanning.
📍Importantly, some participants had experienced mild or moderate COVID, meaning such changes were found not only after a critical course of illness.
📍The researchers suggest that damage to the dopamine system may be one cause of prolonged fatigue, loss of motivation, and cognitive problems after COVID.
