Chronic exposure

Referral to a neurologist for electroneurophysiological assessment is recommended for any individual with suspected neuropathy. The prognosis of n-hexane-induced polyneuropathy is usually good (Huang et al., 1989; Chang, 1990), although it depends on the severity (Smith and Albers, 1997). Recovery may be slow. In a study of 11 patients with moderate to severe neuropathy, all were able to resume normal daily activities within 1-4 years. The sensory disturbance usually resolves much earlier than motor disturbances (Huang et al., 1989; Chang, 1991).
