HYSTERIA (HYSTERICAL
CONVERSION REACTION) IN CHILD
In hysteria, now recognized as a dissociative (conversion)
disorder, the child (usually a preadolescent or an adolescent) with a
psychopathic personality presents with manifestations simulating an organic
disease, say recurrent abdominal pain, sensation of compression of the throat
(globus hystericus), blindness, gait disturbances, paralysis, sensory loss,
urinary retention, seizures or dyspnea.
A good history-taking and clinical workup usually lead to
the correct diagnosis without resorting to painstaking investigations. The
patients has a tendency to be indifferent to the queries and relates
manifestation in a detached manner.
Common Presentations
Hysterical seizures, a common presentation, are remarkable
by absence of tongue-biting, apnea and incontinence. The patient tends to
forcibly to hold the eyes closed and
seizure activity is bizarre. Quite
often, seizures are marked by rhythmic thrusting and writing of trunk.
Nocturnal seizures, stereotyped aura, cyanotic skin changes and postictal
confusion are infrequent in pseudo-seizures seen in hysteria. Moreover, serum
prolactin level remain normal after the pseudo-seizures. EEG too shows no spike
and wave forms or postictal slowing.
Hysterical blindness is characterized by tunnel vision and
absence of papillary abnormality and fundoscopic abnormality.
Hysterical ataxia is characterized by inability to stand or
walk without any deficit on neurologic examination when tested in lying
position. The gait is bizarre and there is extreme lurching on the sides. In
cerebellar ataxia, on the other hand, the patient walks on a wide base and has
difficulty in maintaining in balance.
Hysterical paralysis is characterized by presence of normal
muscle tone, tendon reflexes and plantars, and positive Hoover test. The last
named consists in keeping hand under the allegedly paralysed leg and asking the
patient to raise the normal leg against resistance. As the patient forcefully
lifts the leg, the examiner’s hand can feel downward pressure of the effected
leg against the examiner’s hand. This occurs only in hysteria.
Hyperventilation syndrome is a state characterized by
dyspnea, tightness or stabbing pain in chest, headache, abdominal pain, muscle
pains, paresthesia, palpitations, dryness of mouth, vertigo, choking, weakness,
blurred vision, confusion and syncope. The syndrome occurs in episodes. The
causes include acute anxiety state, uremia, salicylate poisoning, hypernatremic
dehydration, diabetic ketoacidosis, and Reye syndrome. Treatment is primarily
of the cause.
Management
Treatment of hysteria is primarily early detection and
symptom removal. The symptom removal (normalization) can be attained by
insisting on adherence to routine and contracting differential reinforcing and
removal of secondary reinforcers. The child should never be accused of feigning
the symptoms. Appropriate antidepressants and anxiolytics may be warranted.
