It seems to me that this is not schizophrenia. Most likely, with such behavior, he wants to attract attention. And he did it very well.
According to my doctor friend, to whom I showed several videos of Gennady Gorin from the city of Oryol, he clearly suffered a stroke (judging by aphasia), schizophrenia and / or mental retardation are also quite possible. In general, the person is clearly unwell.
Gennady Gorin has similar symptoms to Huntington's disease. But it is possible that he also has schizophrenia. It is difficult to give an exact answer based only on his video.
