I had a short psychotic episode. what are the chances of having another? i do not suffer from psychosis or any mental disorders. the diagnosis was made after the doctors could not find a medical reason for the quick onset of psychotic features with halluc

That : That is a very tough question to answer. A brief reactive psychosis normally lasts one day to less than one month. First, i can not find literature that pins down an actual percentage for recurrence. Most often a person with a brief reactive psychotic episode will return to normal function and the majority will not suffer another psychotic event. Most often there is a markedly stressful triggering event. When the psychosis occurs in the absence of a stressor or trigger the chance of a recurrence is higher. Chances or recurrence are also higher in people with particular types of personality disorders. It the psychotic event is acutally just the initial episode in someone with bipolar disorder (when depressed or manic) or in someone who is schizoprhenic then more psychotic episodes would be likely.

Impossible to predic: Without a diagnosis as to why it occurred it is impossible to predict if it would reoccur. I have seen this occur from sleep apnea which was overlooked. If you temporarily lose oxygen to your brain by not breathing enough at night or during a nap it can easily happen. I know because it happened to me. It is often overlooked. Have that looked into. Otherwise view it as a temporary glitch.
