Conversation: The conversation between human and AI assistant.
[|Human|] My son is 11 yrs old and has complained twice over the past two days of having blackened vision for short bursts of time (3-4 sec) as he describes it. He also indicates he looses orientation and for slpit moment does not know where or why he is in the place that he is? Can you please advise me? Thank you Rene Calafato
[|AI|]  Blackened vision for short period of time it can be an emergency, serious causes and disorders can do this, and the fact he feels disoriented too is a red flag. A detailed history and complete physical exam and possible imaging is warranted I highly recommend visiting his doctor as soon as possible to role out TIA (transient ischemic attacks) , it's rare in child Chat Doctor. Another neurological disorder to worry about is narcolepsy apoplexy disorder, in which the child seems to black out and loss his tone and never recall it, which can present it your children case. I hope this helps
