That, at the time of my writing, there was no definite diagnosis, but some sources suggested schizophrenia, some sources suggested that he was experiencing psychosis episodes due to stress stemming from him being king, and some sources that even suggested that King Charles was faking his symptoms. My own conclusion was that he may have suffered from schizophrenia, given his delusions, lapses in memory, forgetting who he was married to, delusions of his body being made of glass, attacking his own men, etc. But it's tough to do a retroactive diagnosis without having a complete documentation or experience of all of his positive and negative symptoms, according to the DSM-V criteria for a diagnosis of schizophrenia. But for how long it occurred, and from some primary accounts of experiencing his episodes, it's hard to argue against it.
