title: [Neurologic complications of drug addiction. General aspects. Complications caused by cannabis, designer drugs and volatile substances].
abstract: When a patient presents a neurological disorder, it is important to consider drugs is a possible cause. The risk to suffer neurological complications by drugs is unknown. It is difficult to calculate the number of drug addicts or the number of occasional drug users. It is important take into account that some patients are using more than one drug. The acute use of cannabis induces important changes in cognition and psychomotor performance. No signs of neurotoxicity were found in chronic marihuana users. Some "designer drugs" can induce neurotoxicity. MDMA, that have hallucinogenic activity, is a neurotoxin in animals. MPTP kill dopaminergic neurons in the substantia nigra, inducing Parkinson's disease. Volatile substances containing toluene or n-hexane are usually abused by young people. They can produce neurological damage when are used chronically (p. ex. cerebral atrophy or peripheral neuropathies).
