Psychological Disorders Excessive alcohol consumption is associated with depression, a common problem among the elderly. Physiologically, levels of serotonin and norepinephrine are altered in the brain as people get older. Symptoms of depression may result from physical illnesses such as diabetes, thyroid disorders or Parkinson's disease. Depression can result from side effects of medications used to treat these diseases. After age 65, drinkers are 16 times more likely to die of suicide, which is often precipitated by depression.
Older adults have a higher suicide rate than any other subgroup.
Making the Diagnosis Because symptoms can be so similar for alcoholism, diseases of later life and adverse drug reactions, it is important to develop diagnostic procedures. No one sign is indicative of alcoholism in the elderly, but several indicators, especially in multiples, are highly suspicious. On physical exams, remember to note bruises, abrasions and scars that can suggest frequent falls. Cigarette burns on the fingers can suggest falling asleep or passing out. Lab values need to be compared with elderly patients that are not alcoholic.
