There aremany questions and conflicting research concerning
the nature of the relationship between depression and
dementia, i.e., are they coincidental, unidirectionally
causal, mutually influencing or do they share a common
pathophysiology. Normal and pathological aging will be
reviewed with a focus on the differences between crystallized
and fluid intelligence. Effects of depression on cognition
as individual’s age are addressed. Depression primarily
impairs reaction time and some executive functions, such as
mental flexibility, such that executive functions can appear
impaired. There has been no demonstration of a consistent
disturbance inmemory functioning resulting fromdepression
alone, whereas dementia is characterized by memory loss.
Nonetheless memory complaints are ubiquitous amongst the
elderly, regardless of whether they are healthy, depressed
or dementing. No consistent and agreed upon terminology
is apparent throughout the literature on the relationship
between dementia and depression, confounding a current
understanding. For example, DSM-5 criteria for a diagnosis
of depression may currently result in an under-reporting of
major depression because elder patients tend demonstrate
fewer symptoms and tend to focus on somatic and/or
cognitive complaints rather than on mood issues. Thus, a
nosology is proposed to help clarify these issues. Depression
confounds the diagnosis of dementia and vice versa. Current
research has not provided a definitive understanding of this
complex relationship. Recent studies have suggested that
the magnitude and trajectory of depressive symptomatology
have been underappreciated. Perhaps the single greatest
problem in understanding the relationship between
dementia and depression is the heterogeneous nature of
the illnesses themselves. Clarification can only come when
careful specification of each group is made. In effect, apples
must be compared with apples and not with oranges.
