What is MPTP?

MPTP is a chemical compound that can cause severe and irreversible damage to dopaminergic neurons in the brain. This results in symptoms resembling Parkinson's disease. In the 1980s, there was an outbreak of Parkinsonian symptoms among young opioid addicts who unknowingly consumed MPTP instead of the intended drug, MPPP. The ingestion of MPTP left many of these individuals completely paralyzed and unable to move or communicate, as MPTP effectively destroyed the dopaminergic neurons responsible for movement and motivation 1.

MPTP specifically targets the dopaminergic neurons in the substantia nigra and the mesocorticolimbic pathway, which are crucial for motor control and mood regulation. The damage it causes is irreversible, making it a potent neurotoxin that can drastically alter the victims' quality of life 2.
