- These findings have been ascribed to vascular complications or hypoxia-ischemia.
- Neuropathological studies showed widespread impairment of the cellular elements.
- Recent studies provided evidence of accelerated brain aging and neurodegeneration.
The predominantly abused illicit substances include cannabis, opiates, cocaine, amphetamine, methamphetamine and their derivatives. Recently, the abuse of new psychoactive substances has become an increasing problem. In human drug abusers a broad spectrum of changes affecting the central nervous system are seen.
