Pre-existing conditions
For 111 of 194 PCC patients, we also obtained their history of pre-existing neurological/psychiatric conditions.
31 of them (27.9%) had pre-existing neurological or psychiatric conditions.
16 of them had a history of depression (n=14) and/or anxiety (n=3).
One had a suspected addiction to alcohol.
One had a history of bulimia.
Nine of them had various neurological conditions, for example, migraine, tinnitus, trigeminal neuralgia, rotatory vertigo, amyloid angiopathy, fibromyalgia, polyneuropathy.
Unfortunately, we did not acquire the information about preexisting conditions from our controls but based on their self-reported no history of neurological and psychiatric diseases, suggesting that they would have no pre-existing conditions.
