ADA terms us Older Adults and I use
elderly. Maybe I am not politically correct, but I use the term(s) I
am comfortable with and I don't always worry about being politically
correct.
Diabetes is an important health
condition for the aging population. The ADA says 26 percent of
patients over the age of 65 years have diabetes and this number is
expected to increase rapidly in the coming decades. Older
individuals with diabetes have higher rates of premature death,
functional disability, and coexisting illnesses, such as
hypertension, coronary heart disease, and stroke, than those without
diabetes – and the list goes on. Older adults with diabetes have
more geriatric syndromes, such as polypharmacy, cognitive impairment,
urinary incontinence, injurious falls, and persistent pain.
Screening for diabetes complications in
older adults also should be individualized and periodically
revisited, since the results of screening tests may impact
therapeutic approaches and targets. Older adults are at increased
risk for depression and should therefore be screened and treated
accordingly. Diabetes management may require assessment of medical,
functional, mental, and social domains. This may provide a framework
to determine targets and therapeutic approaches. Particular
attention should be paid to complications that can develop over short
periods of time and/or that would significantly impair functional
status, such as visual and lower-extremity complications.
Diabetes increases the incidence of
all-cause dementia, Alzheimer disease, and vascular dementia when
compared with rates in people with normal glucose tolerance. The
effects of hyperglycemia and hyperinsulinemia on the brain are areas
of intense research interest. Poor glycemic control is associated
with a decline in cognitive function, and longer duration of diabetes
worsens cognitive function. Older adults with diabetes should be
carefully screened and monitored for cognitive impairment.
It is important to prevent hypoglycemia
to reduce the risk of cognitive decline and to carefully assess and
reassess patients’ risk for worsening of glycemic control and
functional decline. Older adults are at higher risk of hypoglycemia
for many reasons, including insulin deficiency and progressive renal
insufficiency. In addition, older adults tend to have higher rates
of unidentified cognitive deficits, causing difficulty in complex
self-care activities - glucose monitoring, adjusting insulin doses,
etc.. These deficits have been associated with increased risk of
hypoglycemia and with severe hypoglycemia linked to increased
dementia. Therefore, it is important to routinely screen older
adults for cognitive dysfunction and discuss findings with the
caregivers. Hypoglycemic events should be diligently monitored and
avoided, whereas glycemic targets and pharmacological interventions
may need to be adjusted to accommodate for the changing needs of the
older adult.
At least they do make the following
statements. For patients with advanced diabetes complications,
life-limiting comorbid illness, or substantial cognitive or
functional impairment, it is reasonable to set less intensive
glycemic target goals. These patients are less likely to benefit
from reducing the risk of microvascular complications and more likely
to suffer serious adverse effects from hypoglycemia. However,
patients with poorly controlled diabetes may be subject to acute
complications of diabetes, including dehydration, poor wound healing,
and hyperglycemic hyperosmolar coma. Glycemic goals at a minimum
should avoid these consequences.
