A new study published in The Lancet Psychiatry revealed that one-third of individuals who survived COVID-19 have long-term neurological symptoms. 

The study, published Tuesday, examined the “effects of COVID-19 on brain health.”

It concluded that COVID-19 was “associated with increased risk of neurological and psychiatric outcomes.” 

The study’s authors learned that the risk of stroke and dementia was elevated due to a COVID-19 diagnosis. 

They also found a connection between COVID-19, anxiety and mood disorders. 

According to CNN, this study is the largest of its kind and involved 236,000 COVID-19 patients. 

Researchers observed that those with COVID-19 had a 44% increased risk for neurological and psychiatric illness than people recovering from other respiratory conditions like the flu. 

Similar studies on COVID-19 and its relationship with neurological disorders have been conducted in the past. 

A study titled Posttraumatic Stress Disorder in Patients After Severe COVID-19 Infection was published in JAMA Psychiatry in February. 

This study evaluated 381 White patients who recovered from COVID-19. Out of this group, 30% were found to have PTSD, while others suffered from anxiety and psychotic disorders. 

Another study, published in the Journal Neurology: Clinical Practice in December, revealed that neurological complications could occur even in moderate cases of COVID-19. 

A limitation of the Lancet Psychiatry study is its use of routine healthcare data instead of research data, CNN reported.
