Mikhail Gorbachev (Михаи́л Серге́евич Горбачёв; 1931-2022) was the last leader of the Soviet Union (USSR; Chairman of the Presidium of the Soviet Supreme) from 1988 to its fall in 1991.
He is famous for having implemented policies to end the cold-war:
- -glasnost (“openness”)
- -perestroika (“restructuring”)
To this end, he was awarded to Nobel Peace Prize in 1990.
He is known for a port-wine stain on the right forehead. It is on the dermatome of the ophthalmic branch of the trigeminal nerve (V.I)
At birth, involvement of the V.I branch requires exclusion of a vascular malformation of blood vessels located in the pia matter of the brain. This associated malformation to these port-wine stains is known as the Sturge-Weber syndrome
