Brown was a member of the Spongiform Encephalopathy Advisory Committee (SEAC), a British government advisory board on BSE and related diseases.
Since then he has pursued research related to other neurodegenerative diseases.

Prion research
Brown advanced research related to the role of metals in the cause of prion diseases such as vCJD. Media attention focused on this work when it became associated with that of the farmer
Mark Purdey, who argued that human cases of vCJD might be caused by exposure to
manganese
Manganese is a chemical element; it has Symbol (chemistry), symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition m ...
rather than eating beef from BSE-infected cattle (the medical consensus).
[Charles backs controversial CJD research](_blank)
Lorraine Fraser, ''The Telegraph'', 13 Jan 2002 Both Purdey and Brown agreed that exposure to elevated levels of manganese in the environment could increase the incidence of BSE.
Brown's research showed that manganese causes the protein to change conformation, similar to that seen in prion diseases such as BSE. Additionally, his research also showed that animals with BSE and humans with vCJD had elevated levels of manganese in their brains, and that prion protein extracted from their brains retained some of this manganese. Brown agreed with Purdey only in as far as the potential for manganese to be a risk factor, increasing the likelihood that BSE or another prion disease would occur. Brown supported Purdey in his quest to investigate the potential role of manganese in prion disease and this led to the filming of a program for the BBC in which both Brown and Purdey appeared.
While Purdey pursued the notion that environmental manganese was a cause of BSE (something that arguably could never be proven), Brown suggested that a
