“…It was characterized by increased somnolence, behavioral disturbances, catatonic states and movement disorders. Similar encephalitis sequelae with altered consciousness have been reported during the H1N1 influenza and MERS infection ( Alakare et al, 2010 ). Though initially reported as a rare association in the current pandemic, multiple case reports of encephalitis have been reported since the first wave of infection.…”

Highlights Coronavirus disease 2019 (COVID-19) has emerged as a global health threat. The direct effects of the virus (SARS-CoV-2) on the nervous system are largely unknown. Research on earlier coronavirus infections (SARS, MERS) shows they are neurotropic. Delirium, anosmia, acute behavioral changes, stroke and encephalopathy are common complications of COVID-19. Current and long-term neuropsychiatric effects of COVID-19 and possible pathogenesis are reviewed.

“…There have been 28 reported cases of IAE in adults with 7 further differentiating the clinical syndromes including 3 cases of PRES, 2 cases of MERS, and 2 cases of AHLE (Table ) . In these reports, men are more often affected (19/28; 68%) and patients range in age between 20 and 86 years old.…”

Severe influenza infection represents a leading cause of global morbidity and mortality. Although influenza is primarily considered a viral infection that results in pathology limited to the respiratory system, clinical reports suggest that influenza infection is frequently associated with a number of clinical syndromes that involve organ systems outside the respiratory tract. A comprehensive MEDLINE literature review of articles pertaining to extra‐pulmonary complications of influenza infection, using organ‐specific search terms, yielded 218 articles including case reports, epidemiologic investigations, and autopsy studies that were reviewed to determine the clinical involvement of other organs. The most frequently described clinical entities were viral myocarditis and viral encephalitis. Recognition of these extra‐pulmonary complications is critical to determining the true burden of influenza infection and initiating organ‐specific supportive care.

“…Influenza associated neurologic complications (IANC) include 5 clinical syndromes, eg., encephalitis, myopathy, chorea, transverse myelitis, Guillain-Barre syndrome. Autoimmune post-infectious acute disseminated encephalomyelitis (ADEM) is a late rare complication ( Table 1 ) [ [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] ]. In hospitalized adults with influenza A, influenza associated encephalitis (IAE) is rare, and potentially lethal complication.…”

Influenza A in hospitalized adults uncommonly may present with neurologic manifestations, e.g., encephalitis. Encephalitis is the most common influenza related neurologic complication in adults, However, seizures in hospitalized adults due to influenza are extremely rare. This is a case of a 58 year old female hospitalized for influenza A. On admission, she was confused and obtunded. Her EEG showed diffuse global slowing indicative of encephalitis. On hospital day (HD) #2, she had a seizure. She had no history of a seizure disorder, and was not febrile at the time of the seizure. While seizures are not uncommon in children (febrile seizures) with influenza B, but in adults with influenza A, only a few cases of seizures have been reported. This case was most interesting in having both encephalitis and seizure complicating influenza A. If present, neuropsychiatric manifestations may be due to ostelamivir, but encephalitis and seizures are not among the neurologic adverse effects of ostelamivir. In adults hospitalized with influenza A, clinicians should be alert to the possibility of neurologic complications.
