Are all Switzerland people kill talent? Thomas Oertli, many of us would like know the answer!

"Albert Einstein's son Eduard had a breakdown at about age 20 and was diagnosed with schizophrenia.^[67] His mother cared for him and he was also committed to asylums for several periods, finally, after her death, being committed permanently to Burghölzli, the Psychiatric University Hospital in Zürich, Switzerland.^[68]"~https://en.wikipedia.org/wiki/Albert_Einstein

What would be the diagnosis procedure to confirm one with Schizophrenia Disorder until one must commit permanently in a Psychiatric Wad or Hospital?  We want to know!

What type of test or questionnaire for this type of sickness assessment or diagnosis?

Or, only listen to the third party and confirm his sickness.  If the third party is a storyteller or lier, how are you going to handle this, Thomas Oertli from Switzerland?
