my husband has epilepsy and also pseudo seizures or anxiety induced. Lately he has other things happening and I am concerned He has a hard time staying awake and then also times where he cant sleep at all for long periods of time. He loses his balance very easy, he cant get his words out or finish sentences, his legs will sometimes collapse under him, he drops things a lot like his glass or plate. he is very slow moving and sometimes shuffles when he walks instead of his usual long strides, forgets things very easily. He has a cpap machine. Is there something we should be having him tested for
