Non-hospitalized COVID-19 patients with long-term symptoms have a 85 percent chance of reporting cognitive dysfunction.Some COVID-19 patients experience prolonged symptoms over weeks or months. These individuals are sometimes referred to as "long-haulers." Non-hospitalized COVID-19 long haulers reportedly experience neurological symptoms such as cognitive dysfunction and brain fog.

According to a study by the Annals of Clinical and Translational Neurology, the neurological symptoms in long haul COVID-19 can be persistent. Researchers studied 100 people with COVID-19 long-haul from May to November and found 85 percent reported four or more neurologic symptoms.

The study also showed that 81 percent of respondents reported ongoing issues with memory and thinking (brain fog) while 68 percent said they had headaches, and nearly had problems with loss of taste and smell, numbness or tingling, or muscle pain. Less common symptoms included dizziness, blurred vision, and tinnitus.
