title: [Spongiform leucoencephalopathy after inhaling illicit heroin and due to carbon monoxide-intoxication].
abstract: A spongiform leucoencephalopathy sometimes develops as a result of inhaling illicit heroin as well as due to carbon monoxide-intoxication. Clinically psychiatric symptoms precede a neurological deterioration. Some patients die. After a brief description of several epidemiological and historical-cultural aspects regarding the smoking of opiates, the typical neuroradiological signs such as hypodensity of the white matter in CCT and signal alterations in MRT, and neuropathological sequelae such as intramyelinic vacuolisation are listed. Pathophysiologically an edema of the white matter in the beginning is suspected. Second, a dysfunction of the mitochondria is addressed relying on the particular metabolism of the oligodendrocytes. Since smoking of heroin is an increasingly preferred way of application in all continents and therapeutic options are still lacking, the need of further explanation of the underlying processes is stressed.
