Materials and methods

Type of sensitisation studied:
respiratory
Study type:
case report
Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
In a 5-year follow-up study was described the social consequences for 21 painters who had been diagnosed with chronic toxic encephalopathy. The diagnosis was based on detailed clinical examinations, including interviews about exposure (levels and duration) and subjective symptoms, neuropsychological testing, and neurological and neurophysiological examinations.

The diagnosis was based on detailed clinical examinations, including interviews about exposure (levels and duration) and subjective symptoms, neuropsychological testing, and neurological and neurophysiological examinations.

Results and discussion

Results of examinations:
At the time of diagnosis all the painters had given up their job and five years later 11 worked in other jobs while 10 were receiving the highest disability pension. Clear differences were noted between those who were still working and those who were awarded a pension. The former group were considerably younger, had a history of lower exposure and were less impaired in their intellectual functioning.
