Answer

Distal sensory loss, uncoordinated limb movements, resting tremors, gait ataxia, and a positive Romberg sign have been described after exposure to organic and inorganic mercury. A 2004-2005 study of 197 Minamata Bay residents who were exposed to methylmercury before 1968 found 90% with sensory impairments on the bedside neurologic examination. [64]
