Drugs And Mental Health
Bayani Gaba-gaba
Paracetamol, alcohol, caffeine and heroin are all, in the strict biological sense, drugs: substances that alter how the body or the nervous system functions once they are absorbed into the blood. What separates them is not whether they act on the brain, but how they act, how strong that action is, and what legal controls exist around their use.
This topic explains what a drug is and the difference between legal and illegal drugs, the specific dangers of heroin, cannabis and cocaine, and how paracetamol acts on the nervous system. It then covers the effects of alcohol on the nervous system and liver, before turning to the biology of two common mental illnesses, schizophrenia and depression, and three conditions that progressively affect brain function: Alzheimer's disease, vascular dementia and Parkinson's disease.
