NEUROLOGICAL SYMPTOMS COMMON IN COVID-19 PATIENTS: A RETROSPECTIVE OBSERVATIONAL STUDY.

ABSTRACT

In December 2019, a novel coronavirus outbreak spread rapidly all over the world. The virus is known to be neuroinvasive, but much is still unknown. In this study, we aimed to present the main neurologic symptoms in patients who were diagnosed with coronavirus disease 2019 (COVID-19). The study was conducted retrospectively by phoning 156 patients in Turkey diagnosed with COVID-19 through real-time polymerase chain reaction; only 100 patients could be reached. Data about their demographics, initial symptoms, neurological symptoms, and sleeping habits were collected. During the disease process, 66% had at least one neurological symptom, 55% had central nervous system symptoms, 42% had peripheral nervous system symptoms, and 64% had sleep disturbances and myalgia. Impaired consciousness, smell and taste impairments, and sleep disturbances were significantly higher in patients with positive chest computed tomography imaging (p < 0.05). Neurological symptoms were observed in COVID-19, as in other coronaviruses. Headache in particular was the most common symptom in our population. In patients with respiratory system findings, the detection of certain neurological symptoms such as smell-taste impairments, impaired consciousness, and sleep disorders were more common. We concluded that COVID-19 patients should be approached in a more holistic way, taking the nervous system into account.
