Research recently published in the journal Neurology has
suggested that one in seven Americans could be suffering from a
worrying sleep condition classed as confusion arousal or 'sleep
Completely different from morning tiredness, sleep drunkenness includes symptoms such as forgetfulness, brief mo-ments of confusion, personality changes and even violent behaviour upon sudden awakening. It is believed to affect around 15 percent of Americans.
Of those 19,000 people interviewed, episodes of sleep drunkenness were most common in individuals already suffering from sleep disorders (around 70 per cent), as well as those with mental health disorders such as bipolar (37 per cent) and those on medication, particularly antidepressants (31 per cent).
Lead author of the report, Dr Maurice Ohayon of Stanford University said, "These episodes of confused awakening have not gotten much attention, but given that they occur at a high rate in the general population, more research should be done on when they occur and whether they can be treated."
