Dr. Niman,
My nephew contracted a severe case of H1N1, was hospitalized for a couple of weeks with greatly diminished lung function. He was tested positive for the virus.
Last year he suffered a severe neurological disorder, characterized by muscular tics, Tourettes like verbal outbursts, and seizures. After about a year, the symptoms have subsided somewhat.
I am now seeing reports of high school age students suffering very similar symptoms, most notable in Le Roy High School in New York. This cluster was publicized mostly by one of the sufferers on you-tube, and has since been followed by the media. However, I suspect that isolated cases, like my nephew, are not being noticed. The HIPAA act would tend to discourage communications about isolated instances of these symptoms. Particularly because, as in my nephew's case, they are likely to withdraw from public education until the symptoms subside.
Has there been any coordinated follow up of diagnosed teenagers for neurological symptoms? I am beginning to suspect there should be.
Do you think that this is a possible consequence of teenage infection with the virus?
Rob

Rob,

Neurological isues with flu have been around for some time. In fact the first influenza ever isolated, WS/33, in 1933 was passed in mouse brains to produce WSN/33, which was neurotropic (and was also H1N1). Similarly, the Qinghai stain of H5N1 was neurotropic, as were other H5N1 isolates.
Although I remain suspect of the cluster in New York, potential neurological complications of influenza infections, especially for a novel virus like H1N!pdm09, are a very real possibility.

The efforts to create WSN/33 were associated with reports of schizophrenia in survivors of the 1918 pandemic, caused by an H1N1 which had many similarities to H1N1pdm09.

Influenza virus infection of the respiratory tract is associated with a range of neurologic complications. The emergence of 2009 pandemic influenza A (H1N1) virus has been linked to neurological complications, including encephalopathy and encephalitis.

Perhaps the most commonly cited paper is one by researchers at Columbia University, which associated a mother's influenza with her child's risk of mental illness. In that landmark study, researchers collected blood samples from 12,000 pregnant women in Alameda County, California, between 1959 and 1966 and monitored their sons and daughters for more then three decades. Children born to women who had been infected with flu were three to seven times more likely to develop schizophrenia later in life, the study concluded.

Epidemiological, viral, behavioral and neuropathological evidence suggests that some influenza epidemics were neurovirulent. Re-examination of the data from the lethal 1918 pandemic armed with recent observations about the influenza virus implicates a neurovirulent influenza virus in manic-depressive disease, schizophrenia and Parkinson's disease. The neurovirulence seems to have been related to the species of neuraminidase.

Neurotropic E627K PB2 Mutations in All Qinghai H5N1 Isolates

Recombinomics Commentary
July 7, 2005

The paper in tomorrow's Science describes sequences in 4 more isolates from Qinghai lake. There are two isolates from bar headed geese (A/BH Goose/QH/1/05(H5N1) and A/BH Goose/2/05) as well as greater black headed gull, Gbh Gull/QH/1/05 (H5N1) and a brown headed gull, Bh Gull/QH/1/05 (H5N1)...
