PSYCHOGENIC y SKIN LESIONS - WHAT ARE THEY
?
Words For The Family.
Introduction
Many disorders of the skin are very
difficult to diagnose with certainty, and may often have multiple causes.
Sometimes there is a psychological factor involved as either the principle or
contributing cause of the problem. The psychological factors may be very mild
or they may be severe, and a person's awareness of these factors as important
in their skin disorder may range from acknowledgment to absolute denial.
There are three principle categories of
psychogenic skin disorders. In each case the skin lesions are caused or at
least exacerbated by the patient.
Care must be taken when offering any of these three diagnoses that every
attempt is made to find any evidence of even the smallest initiating lesion due
to primary skin infection, inflammation, or other cause. While it often happens
that a patient can make a treatable skin condition appear much worse by
nervously picking at the lesions, this is to be differentiated from primary
psychogenic lesions which are in each case initiated by the patient.
Before describing the various kinds of
conditions that can result in psychogenic lesion, let us consider parallels to
more common behaviors, seen every day. Have you ever known someone who
nervously pulled out strands of their hair? Or someone who always chewed off
their fingernails, often leading to infections? How
many of us grind or clench our teeth at times of stress - thinking
subconsciously that we can relieve the stress by doing damage to our teeth? The
skin disorders that we are discussing here are not so different from the above
examples of common behaviors. But, as with everything, there can be extremes of
behavior that can have unfortunate consequences - these behaviors must be
understood and treated.
What
causes it?
As mentioned above, there are three
categories of psychogenic skin disorders, represented by the people who tend to
be involved. They may be described as follows: Type A, generally an
obsessive-compulsive individual, insisting on perfection; Type B, a person who
is given to spells of depression or mania, mostly the type of depression that
leads to agitation rather than lethargy; and Type C, generally involving a
person with strong psychotic tendencies, with more profound mental
disturbances. Type C usually shows distorted behavior of a different character
from that seen for Types A and B. While types A and B are more of the anxious,
depressed or manic types, type C includes those with organic brain conditions
such as Alzheimer's, dementia, and schizophrenia.
One must realize that for each of these
three types of individuals, there are specific types of chemical imbalances or
deficiencies that can be identified in the central nervous system. The skin
disorders are usually a manifestation of a mental disorder which is chemical in
nature, and is a disease where the organ involved happens to be the most
complex of all organs, the brain.
The cause of the brain dysfunction is
generally not known, but since the disorders are sometimes well treated by the
use of medications, it seems clear that chemical imbalances are involved. For
some individuals it appears that certain regions of the brain are not as active
as they should be, or sometimes are more active than desired. In any event, a
chemical imbalance may lead to an undesirable stress reaction and thus result
in behaviors, that in susceptible individuals,
generate sites of chronic skin infection or inflammation.
How
does it progress?
In many people it is the onset of a
depressed state or an anxious state that leads to initiation of skin lesions -
by scratching or picking generally. In the most severe Type C person, other
methods of damaging the skin may be seen, including the use of heat or chemical
agents. In this latter case, surprisingly, the person is the most convinced
that they themselves have nothing to do with their skin disorder. For most,
when the lesions are generated at a time of depression or stress, the lesions
themselves can then make a secondary contribution to the stress or depressed
state, and thus, the disorder feeds on itself, is self-perpetuating, and
promotes a viscious cycle.
How
is it diagnosed?
Failing to find any evidence of primary
skin disease, the most thorough psychological evaluation of the patient is
necessary. Years can be spent trying to treat a skin disorder using
antibiotics, anti-inflammatory agents, and antifungal drugs, only to find out
that a complete cure is effected with an anti-anxiety
drug. For the depressive, Type B disorder, one looks for decreased mood,
feelings of helplessness, insomnia (particularly toward dawn), and loss of
appetite. An irritable or agitated demeanor would be expected, and the patient
is often found to ascribe their skin condition to other causes, even parasitic
infections. The Type B patient doesn't adhere strongly to this parasitic
conviction when shown evidence to the contrary. The Type A, obsessive-compulsive,
person generally will be aware of their behavior toward their skin. Often they
describe an "itch", but upon observation it is generally found that
they look and feel for self perceived imperfections in their skin which they
then seek to eliminate. The signs of a generalized anxiety disorder, common for
this type, are worry, muscle tension, and palpitations. The episodes may be
triggered by events, but the condition is chronic and slowly evolves. The Type
B depressive or manic individual described above is more likely to have a
sudden onset of the condition. The more severe Type C individual will display
all of the signs of serious psychosis, and will generally deny any activity
which could lead to the observed skin condition. The diagnosis is made, then,
on the basis of an observed skin condition without infectious, inflammatory, or
neoplastic cause, along with the observation of associated psychologic states known to possibly predispose to initiation of skin lesions. Often, the
pattern of the lesions is a supplemental diagnostic aid, in that lesions are
generally found only where the person can easily reach.
How
is it treated?
In general, all three of these
psychogenic disorders are treated with psychopharmacologic drug therapy. For
Type A, the anti anxiety drugs are often effective. For Type B, antidepressants
or lithium find great success. And for the Type C, more serious case,
antipsychotic drugs are often combined with group, recreational, and
occupational therapy.
What
to expect.
The treatments suggested above are
continued for some number of months, and can then be tapered off with no
recurrence of the disorder. For those patients who denied the cause of the skin
lesions before treatment, most recover with no awareness of the true nature of their
previous illness. Occasionally such a patient will gain a sudden insight into
their role in the disorder. Sound psychiatric evaluation, diagnosis, drug
treatment, and psychotherapy can be expected to take these people from a state
of near incapacity to full function in fairly short order. The most important
factor in providing such a cure is the awareness of the potential nature of the
problem.
