Previously our research showed in petrol sniffers of nearly 10 years with serious neurological damage, some evidence of brain function recovery after 2 years of abstinence from further sniffing. 

Here we are following up the same sniffers who have now not sniffed for nearly 15 years to determine if there was further recovery in the long term. We will also find out what psychological and lifestyle factors affected long term recovery or sustained impairment among these ex-sniffers.

The aim of this work is to determine what happens to the brain functions in the long term after heavy petrol sniffing and also determine positive and negative impacts on brain function for petrol sniffers to assist the treatment and intervention of current petrol sniffers.
