Damage to the brainstem – the brain’s ‘control centre’ – is behind long-lasting physical and psychiatric effects of severe Covid-19 infection, a study suggests.

Using ultra-high-resolution scanners that can see the living brain in fine detail, researchers from the Universities of Cambridge and Oxford were able to observe the damaging effects Covid-19 can have on the brain.

The study team scanned the brains of 30 people who had been admitted to hospital with severe Covid-19 early in the pandemic, before vaccines were available. The researchers found that Covid-19 infection damages the region of the brainstem associated with breathlessness, fatigue and anxiety.

The majority of people experience extreme fatigue and many suffer post-stress discomfort, a kind of energy crash. Brain fog, lack of concentration and memory loss are also common symptoms.

Some people develop conditions and syndromes such as postural orthostatic tachycardia syndrome (POTS), characterized by dizziness and palpitations when a person is in a upright position. Others develop dysautonomia, which causes palpitations, pressure rises or falls, dizziness and gastric problems.
