title: [Risk, cause and disease in the occupational environment. Neurologic risk factors].
abstract: OBJECTIVE
  In this paper we study the epidemiological criteria and those of etiological investigation which should be considered when analysing and investigating problems with health due to exposure to occupational hazards, with special attention to neurological damage due to chemical or physical contamination or to the ergonometric requirements of the task.
  
  
  METHODS
  We define the part played by occupational hazards in causing disease both professional and related to other occupations. The different preventive models used in the history of prevention of professional hazards are analysed. Particular attention is paid to the so-called socio-technical model which considers illness as dysfunction of the relation man/work. The neurological risk factors are analysed separately; therefore we emphasize the different neurotoxic chemicals, physical and ergonomic agents (the latter may be considered a pandemic in the workplace), and we establish the relationships with the main clinical and functional disorders of the central and peripheral nervous systems and the musculoskeletal system.
