About 20 percent of journalists and 16 percent of seamen in Greece suffer from symptoms of mild cognitive impairment (MCI), which refers to difficulty in remembering recently acquired information, recent research has found. Most of those in the group of 200 journalists interviewed, all from Attica, attributed their symptoms to work-related stress, while the remainder linked it to high blood pressure, the use of alcohol or psychotropic drugs. Of the 1,140 Greek seamen interviewed, 185 presented symptoms of MCI. Nearly all suffered from intense stress and 176 were taking daily medication for chronic diseases. MCI, first described two years ago by scientists at the Mayo Clinic in the US, usually appears in middle age and can be due to genetic, metabolic or cardiovascular causes, injury, an unhealthy lifestyle or overwork.
